serious or fatal injury.
Some Important Safety Precautions for Chain Saw Users
A Summary of Warnings on
kickback and other Selected
Risks – Taken Primarily from
ANSI B 175.1 (See also “Safety
Precautions“ section of this
Owner’s Manual)
Do not rely exclusively upon the safety
devices built into your saw. As a
chainsaw user, you should take several
steps to keep your cutting jobs free from
accident or injury.
Kickback may occur when the nose or
tip of the guide bar touches an object, or
when the wood closes in and pinches
the saw chain in the cut. Tip contact in
some cases may cause a lightning fast
reverse reaction, kicking the guide bar
up and back towards the operator.
Pinching the saw chain along the top of
the guide bar may push the guide bar
rapidly back towards the operator. Either
of these reactions may cause you to lose
control of the saw which could result in
serious personal injury.
Section 5.11 of ANSI B 175.1-2000 sets
certain performance and design criteria
related to chainsaw kickback. STIHL has
developed a color code system using
green and yellow to help you select a
powerhead, bar and chain combination
that complies with the kickback
requirements of the ANSI Standard.
See the sections entitled "Safety
Precautions" and "Specifications" of this
With a basic understanding of
kickback, you can reduce or
eliminate the element of surprise.
Sudden surprise contributes to
Keep a good firm grip on the saw
with both hands, the right hand on
the rear handle, and the left hand on
the front handle, when the engine is
running. Use a firm grip with thumbs
and fingers encircling the chainsaw
handles. A firm grip will help you
reduce kickback and maintain
control of the saw. Don't let go.
Make sure the area in which you are
cutting is free from obstructions. Do
not let the nose of the guide bar
contact a log, branch, or any other
obstruction that could be hit while
you are operating the saw.
Cut at high engine speeds.
Do not overreach or cut above
shoulder height.
Follow manufacturer's sharpening
and maintenance instructions for
the saw chain.
Only use replacement bars and
chains specified by the
manufacturer or the equivalent.
Reduced kickback bars and low
kickback chains are designed to
reduce the risk of kickback injury.
Ask your STIHL dealer about these
Other Safety Precautions
Do not operate a chainsaw with one
hand! Serious injury to the operator,
helpers, bystanders, or any
combination of these persons may
result from one-handed operation. A
chainsaw is intended to be used
with two hands.
Do not operate a chainsaw when
you are fatigued.
Use safety footwear; snug-fitting
clothing; protective gloves; and eye,
hearing, and head protection

This Manual contains operating and
safety instructions for all STIHL 009
series power saws.
Pay special attention to the safety
precautions outlined on pages 4 to 24.
Allow only persons who understand this
Manual to operate your chain saw.
To receive maximum performance and
satisfaction from your STIHL chain saw,
it is important that you read and understand the maintenance and safety
precautions before using your saw.
Contact your STIHL dealer or the
STIHL distributor for your area if you do
not understand any of the instructions in
this Manual.
Because a chain saw is a high-speed
wood-cutting tool, some special safety
precautions must be observed as with
any other power saw to reduce the risk of
personal injury. Careless or improper use
may cause serious or even fatal injury.
STIHL’s philosophy is to continually
improve all of its products. As a result,
engineering changes and improvements
are made from time-to-time.
If the operating characteristics or the
appearance of your saw differs from
those described in this Manual,

The use of any chainsaw
may be hazardous.
The saw chain has many
sharp cutters. If the
cutters contact your flesh,
they will cut you, even if the chain is not
moving. At full throttle, the chain speed
can reach 45 mph (20 m/s). It is important that you read, fully understand
and observe the following safety precautions and warnings. Read the Owner’s
Manual DQG the safety instructions
Pay special attention to the section on
reactive forces.
Reactive forces, including kickback, can
be dangerous. Careless or improper use
of any chainsaw may cause serious or
fatal injury.
All safety precautions that are generally
observed when working with an ax or a
hand saw also apply to the operation of
chainsaws. However, because a chainsaw is a high-speed, fast-cutting power
tool, special safety precautions must be
observed to reduce the risk of personal
Have your STIHL dealer show you how
to operate your chainsaw. Observe all
applicable local safety regulations,
standards and ordinances.
Minors should never be allowed to use a
chainsaw. Bystanders, especially
children, and animals should not be
allowed in the area where a chainsaw is
in use. Never let the saw run unattended.
Store it in a locked place away from
children and empty the fuel tank before
storing for longer than a few days.
Do not lend or rent your
chainsaw without the
Owner‘s Manual. Be sure
that anyone using your
saw reads and understands the information contained in this
These safety precautions and warnings
apply to the use of all STIHL chainsaws.
Different models may have different
parts and controls. See the appropriate
section of your Owner’s Manual for a
description of the controls and function
of the parts of your model saw.
Safe use of a chainsaw involves
1. the operator
2. the saw
3. the use of the saw.
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol) which might impair vision,
dexterity or judgment.
Do not operate a chainsaw when you are
fatigued. Be alert – If you get tired while
operating your chainsaw, take a break.
Tiredness may result in loss of control.
Working with any chainsaw can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
a chainsaw.
Prolonged use of chainsaws (or other
machines) exposing the operator to
vibrations may produce whitefinger
disease (Raynaud’s phenomenon) or
carpal tunnel syndrome. These conditions
reduce the hand’s ability to feel and
regulate temperature, produce numbness and burning sensations and may
cause nerve and circulation damage and
tissue necrosis.
All factors which contribute to whitefinger
disease are not known, but cold weather,
smoking and diseases or physical conditions that affect blood vessels and blood
transport, as well as high vibration levels
and long periods of exposure to vibration
are mentioned as factors in the development of whitefinger disease. In order to
reduce the risk of whitefinger disease
and carpal tunnel syndrome, please
note the following:
The STIHL 009 is not equipped with an
antivibration (AV) system.
Many STIHL models are available
with an anti-vibration (“AV”) system
designed to reduce the transmission
of vibrations created by the engine
and cutting attachment to the
operator’s hands. An AV system is
recommended for those persons
using chainsaws on a regular or
sustained basis.
Wear gloves and keep your hands
warm. Heated handles, which are
available on most STIHL powerheads, are recommended for cold
weather use.
Keep the saw chain sharp and the
saw, including the AV system, well
maintained. A dull chain will increase cutting time, and pressing a
dull chain through wood will increase the vibrations transmitted to
your hands. A saw with loose components or with damaged or worn
AV buffers will also tend to have
higher vibration levels.
Maintain a firm grip at all times, but
do not squeeze the handles with
constant, excessive pressures.
Take frequent breaks.
All the above mentioned precautions do
not guarantee that you will not sustain
whitefinger disease or carpal tunnel
syndrome. Therefore, continual and
regular users should monitor closely the
condition of their hands and fingers.
If any of the above symptoms appear,
seek medical advice immediately.
To reduce the risk of injury, the operator
should wear proper protective apparel.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Avoid loosefitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become entangled with the saw or
brush. Wear overalls or jeans with a
reinforced cut retardant insert or cut
retardant chaps.
Protect your hands with
gloves when handling saw
and saw chain.
Heavyduty, nonslip
gloves improve your grip
and protect your hands.
Good footing is most
important in chainsaw
work. Wear sturdy boots
with nonslip soles.
Steel-toed safety boots
are recommended.
To reduce the risk of injury to your eyes
never operate a chainsaw unless
wearing goggles or properly fitted safety
glasses with adequate top and side
protection complying with your national
Wear an approved safety
hard hat to protect your
head. Chainsaw noise may
damage your hearing.
Always wear sound
barriers (ear plugs or ear mufflers) to
protect your hearing. Continual and
regular users should have their hearing
checked regularly.
Accidental acceleration of the engine
can cause the chain to rotate. During
operation, the powerhead muffler and
the material around it reach extremely
high temperatures. Avoid touching the
hot muffler, you could receive serious
Parts of the chainsaw; for illustrations
and definitions of the parts see the
chapter on “Main Parts of Saw”.
Never modify a chainsaw in any way.
Only attachments and parts supplied by
STIHL or expressly approved by STIHL
for use with the specific STIHL saw
models are authorized. Although certain
unauthorized attachments are useable
with the STIHL powerhead, their use
may, in fact, be extremely dangerous.
001BA115 KN
Always stop the engine before putting a
chainsaw down or carrying it. Carrying a
chainsaw with the engine running is
extremely dangerous.
%\KDQGWhen carrying your saw by
hand, the engine must be stopped and
the saw must be in the proper position.
The chain guard (scabbard) should be
over the chain and the guide bar, which
should point backwards. When carrying
your saw, the bar should be behind you.
%\YHKLFOHWhen transporting in a
vehicle, keep chain and bar covered with
the chain guard. Properly secure your
saw to prevent turnover, fuel spillage
and damage to the saw.
Grip the front handle and place the
muffler away from the body.
Take off the chain guard and inspect for
safety in operation. For assembly, follow
the procedure described in the chapter
“Mounting the Bar and Chain” of your
Owner’s Manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch.
Before replacing any bar and chain,
see the sections on “Specifications”,
"Kickback" and the "ANSI B 175.1-2000
chainsaw kickback standard" in this
Proper tension of the chain is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your manual.
Always make sure the hexagonal nut(s)
for the sprocket cover is (are) tightened
securely after tensioning the chain.
Never start the saw with the sprocket
cover loose. Check chain tension once
more after having tightened the nut(s)
and thereafter at regular intervals (whenever the saw is shut off). If the chain
becomes loose while cutting, shut off the
engine and then tighten. Never try to
tighten the chain while the engine is
Your STIHL chainsaw uses an oil-gasoline mixture for fuel (see chapter “Fuel”
of your Owner’s Manual).
Gasoline is an extremely flammable fuel.
If spilled or ignited by a spark or other
ignition source, it can cause fire and
serious burn injury or property damage.
Use extreme caution when handling
gasoline or fuel mix.
Do not smoke or bring any
fire or flame near the fuel
or the chainsaw. Note that
combustible fuel vapors
may be vented from the
fuel system.
the risk of burns or other personal injury
from escaping gas vapor and fumes,
remove the fuel filler cap on the STIHL
product carefully so as to allow any
pressure build-up in the tank to release
slowly. Never remove fuel filler cap while
engine is running.
Select bare ground for fueling and move
at least 10 feet (3 m) from fueling spot
before starting the engine. Wipe off any
spilled fuel before starting your saw, and
check for leakage.
Check for fuel leakage while refueling
and during operation. If fuel or oil leakage
is found, do not start or run the engine
until leak is fixed and spilled fuel has
been wiped away. Take care not to get
fuel on your clothing. If this happens,
change your clothing immediately.
Different models may have different fuel
Fuel your chainsaw in well-ventilated
areas, outdoors only. Always shut off the
engine and allow it to cool before refueling. Gasoline vapor pressure may build
up inside the gas tank of a two cycle
engine depending on the fuel used, the
weather conditions, and the venting
system of the tank. In order to reduce
In order to reduce the risk of fuel spillage
and fire from an improperly tightened
fuel cap, correctly position and tighten
the fuel cap in the fuel tank opening.
Unit vibrations can cause an improperly
tightened fuel filler cap to loosen or come
off and spill quantities of fuel. In order to
reduce the risk of fuel spillage and fire,
tighten fuel filler cap by hand with as
much force as possible.

STIHL combination wrench
or other similar tool can be
used as an aid in tightening
slotted fuel filler caps.

To do this with this STIHL
cap, raise the grip on the
top of the cap until it is upright at a 90° angle. Insert
the cap and the fuel tank opening with
the triangular marks on the grip of the
cap and on the fuel tank opening lining
up. Using the grip, turn the cap firmly
clockwise as far as it will go (approx. a
quarter turn).
Fold the grip flush with the
top of the cap. If the grip
does not lie completely
flush with the cap and the
detent on the grip does not fit in the corresponding recess in the filler neck, the
cap is not properly seated and tightened
and you must repeat the above steps.
The chain brake must be engaged when
starting the saw.
Grip the front handlebar of the saw firmly
with your left hand and press down.
For saws with a rear handle level with
the ground, put the toe of your right foot
into the rear handle and press down.
With your right hand pull out the starter
grip slowly until you feel a definite
resistance and then give it a brisk,
strong pull.
Your chainsaw is a one-person saw.
Do not allow other persons to be near
the running chainsaw. Start and operate
your saw without assistance. For specific starting instructions, see the appropriate section of the Owner’s Manual.
Proper starting methods reduce the risk
of injury. Do not drop start. This method
is very dangerous because you may
lose control of the saw.
There are two recommended methods
for starting your chainsaw.
With the ILUVWPHWKRGthe chainsaw is
started on the ground. Make sure the
chain brake is engaged (see “Chain
Brake” chapter in your Owner’s Manual)
and place the chainsaw on firm ground
or other solid surface in an open area.
Maintain good balance and secure
The VHFRQGrecommended PHWKRGfor
starting your chainsaw allows you to start
the saw without placing it on the
ground. Make sure the chain brake is
engaged, grip the front handle of the
chainsaw firmly with your left hand.
Keep your arm on the front handle in a
locked (straight) position. Hold the rear
handle of the saw tightly between your
legs just above the knees. Maintain good
balance and secure footing. Pull the
starting grip slowly with your right hand
until you feel a definite resistance and then
give it a brisk, strong pull.
Be sure that the guide bar and chain are
clear of you and all other obstructions
and objects, including the ground. When
the engine is started, the engine speed
with the starting throttle lock engaged
will be fast enough for the clutch to
engage the sprocket and, if the chain
brake is not activated, turn the chain.
If the upper quadrant of the tip of the bar
touches any object, it may cause kickback to occur (see section on reactive
forces). To reduce this risk, always
engage the chain brake before starting.
Never attempt to start the chainsaw
when the guide bar is in a cut or kerf.
When you pull the starter grip, do not
wrap the starting rope around your
hands. Do not allow the grip to snap
back, but guide the starter rope slowly
back to permit the rope to rewind
properly. Failure to follow this procedure
may result in injury to hand or fingers
and may damage the starter mechanism.
To reduce the risk of personal injury from
loss of control or contact with the
running chain, do not use a saw with
incorrect idle adjustment. At correct idle
speed, the chain should not rotate. For
directions to adjust idle speed, see the
appropriate section of your Owner’s
Manual. If you cannot set the correct idle
speed, have your STIHL dealer check
your saw and make proper adjustments
or repairs.
After adjusting a chain, start the saw, let
the engine run for a while, then switch
engine off and recheck chain tension.
Proper chain tension is very important at
all times.
Operate the chainsaw under good
visibility and daylight conditions only.
Your chainsaw produces
poisonous exhaust fumes
as soon as the combustible
engine is running.
These gases (e.g. carbon
monoxide) may be colorless and odorless.
To reduce the risk of serious or fatal
injury from breathing toxic fumes, never
run the chainsaw indoors or in poorly
ventilated locations. Ensure proper ventilation when working in trenches or other
confined areas.
Use of this product (including sharpening the saw chain) can generate dust,
mists and fumes containing chemicals
known to cause respiratory disease, cancer, birth defects, or other reproductive
harm. If you are unfamiliar with the risks
associated with the particular dust, mist
or fume at issue, consult your employer,
governmental agencies such as OSHA
and NIOSH and other sources on
hazardous materials. California and
some other authorities, for instance,
have published lists of substances
known to cause cancer, reproductive
toxicity, etc.
Control dust (such as sawdust), mists
(such as oil mist from chain lubrication)
and fumes at the source where possible.
In this regard use good work practices
and follow the recommendations of
OSHA / NIOSH and occupational and
trade associations. When the inhalation
of toxic dust, mists and fumes cannot be
eliminated, the operator and any bystanders should always wear a respirator
approved by NIOSH / MSHA for the type
substance at issue.
Breathing asbestos dust is dangerous
and can cause severe or fatal injury, respiratory illness or cancer. The use and
disposal of asbestos containing products
have been strictly regulated by OSHA
and the Environmental Protection Agency. Do not cut or disturb asbestos, asbestos containing products (e.g. asbestos
containing drywall or other construction
products), or products such as pipes
which are wrapped or covered with asbestos insulation. If you have any reason
to believe that you might be cutting asbestos, immediately contact your employer
or a local OSHA representative.
The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
hot for a while after stopping the engine.
To reduce risk of burns do not touch the
muffler and other parts while they are
hot. Don’t work alone. Keep within calling
distance of others in case help is
Your chainsaw is equipped with a chain
catcher. It is designed to reduce the risk
of personal injury in the event of a thrown
or broken chain. From time to time the
catcher may be damaged or removed.
To reduce the risk of personal injury,
do not operate a chainsaw with a
damaged or missing catcher.
Inspect buffers periodically. Replace
damaged, broken or excessively worn
buffers immediately, since they may
result in loss of control of the saw.
A “sponginess” in the feel of the saw,
increased vibration or increased
“bottoming” during normal operation
may indicate damage, breakage or
excessive wear. Buffers should always
be replaced in sets. If you have any
questions as to whether the buffers
should be replaced, consult your STIHL
servicing dealer.
Take extreme care in wet and freezing
weather (rain, snow, ice). Put off the
work when the weather is windy, stormy
or rainfall is heavy.
Avoid stumbling on obstacles such as
stumps, roots or rocks and watch out for
holes or ditches. Clear the area where
you are working. Be extremely cautious
when working on slopes or uneven
ground. There is increased danger of
slipping on freshly debarked logs.
To reduce the risk
of serious or fatal
injury to the operator or bystanders,
never use the saw
with one hand.
You cannot control reactive forces and
you may lose control of the saw, which
can result in the skating or bouncing of
the bar and chain along the limb or log.
Even for those compact saws designed
for use in confined spaces, one-handed
operation is dangerous because the
operator may lose control.
001BA018 LA
001BA087 LÄ
Grip: Always hold the saw firmly with
both hands when the engine is running.
Place your left hand on front handle bar
and your right hand on rear handle and
throttle trigger. Left-handers should
follow these instructions too.
Wrap your fingers tightly around the
handles, keeping the handles cradled
between your thumb and forefinger.
With your hands in this position, you can
best oppose and absorb the push, pull
and kickback forces of your saw without
losing control (see section on reactive
forces). Make sure your chainsaw
handles and grip are in good condition
and free of moisture, pitch, oil or grease.
Do not operate your chainsaw with the
starting throttle lock engaged. Cutting
with the starting throttle lock engaged
does not permit the operator proper
control of the saw or chain speed.
Do not cut any material other than wood
or wooden objects.
Use your chainsaw for cutting only.
It is not designed for prying or shoveling
away limbs, roots or other objects.
When sawing, make sure that the saw
chain does not touch any foreign
materials such as rocks, fences, nails
and the like.
Such objects may be flung off, damage
the saw chain or cause the saw to
001BA031 LÄ
Never touch a chain with your hand or
any part of your body when the engine is
running, even when the chain is not
rotating. The chain continues to rotate
for a short period after the throttle trigger
is released.
Never work on a ladder, or on any other
insecure support. Never use the saw
above shoulder height.
Never work in a tree unless you have
received specific, professional training
for such work, are properly secured
(such as tackle and harness system or a
lift bucket), have both hands free for
operating the chainsaw in a cramped
environment and have taken proper
precautions to avoid injury from falling
limbs or branches.
In order to keep control of your saw,
always maintain a firm foothold.
Reactive forces may occur any time the
chain is rotating. Reactive forces can be
dangerous! In any chainsaw, the
powerful force used to cut wood can be
reversed (and work against the operator). If the rotating chain is suddenly
stopped by contact with any solid object
like a log or branch or is pinched, the
reactive forces may occur instantly.
These reactive forces may result in loss
of control which may, in turn, cause
serious or fatal injury. An understanding
of the causes of these reactive forces
may helpyou avoid loss of control.
The most common reactive forces are
– kickback,
– pushback,
– pull-in.
Kickback may occur when
the moving saw chain near
the upper quadrant of the
bar nose contacts a solid
object or is pinched.
001BA035 LÄ
Don’t put pressure on the saw when
reaching the end of a cut. The pressure
may cause the bar and rotating chain to
pop out of the cut or kerf, go out of
control and strike the operator or some
other object. If the rotating chain strikes
some other object, a reactive force may
cause the moving chain to strike the
001BA093 LÄ
001BA082 KN
Position the chainsaw in such a way that
your body is clear of the cutting attachment whenever the engine is running.
Stand to the left of cut while bucking.
The reaction of the cutting force of the
chain causes a rotational force on the
chainsaw in the direction opposite to the
chain movement. This may fling the bar
up and back in an uncontrolled arc
mainly in the plane of the bar. Under
some cutting circumstances the bar
moves towards the operator, who may
suffer severe or fatal injury.
Kickback may occur when the nose of
the guide bar is pinched unexpectedly,
unintentionally contacts solid material in
the wood or is incorrectly used to begin
a plunge or boring cut.
It may also occur during limbing.
The greater the force of the kickback
reaction, the more difficult it becomes for
the operator to control the saw. Many
factors influence the occurrence and
force of the kickback reaction. These
include chain speed, the speed at which
the bar and chain contact the object, the
angle of contact, the condition of the
chain and other factors.
The type of bar and saw chain you use
is an important factor in the occurrence
and force of the kickback reaction.
Some STIHL bar and chain types are
designed to reduce kickback forces.
STIHL recommends the use of reduced
kickback bars and low kickback chains.
Section 5.11 of ANSI standard B 175.1–
2000, sets certain performance and
design criteria related to chainsaw

Never operate your chainsaw without a
front hand guard. In a kickback situation
this guard helps protect your left hand or
other parts of your body. In addition,
removal of the hand guard on a saw

the chain brake.
STIHL recommends the use of the STIHL
Quickstop chain brake on your powerhead with green labeled reduced kickback bars and low kickback chains.

system designed to reduce the risk of
injury in certain kickback situations.
It is called a Quickstop chain brake.
The Quickstop is available as standard
equipment on your STIHL chainsaw and
is available for installation on most older
STIHL saws. Ask your dealer to retrofit
your older model saw with a chain brake.
When a kickback occurs, the guide bar
may rotate around the front handle. If the
cutting position is such that the operator’s
left hand is gripping the front handle
behind the hand guard, and if the left
hand rotates around the front handle and
makes a sufficiently forceful contact with
the front hand guard, which is the Quickstop activating lever, this contact will
activate the Quickstop. The chain brake
on most new model STIHL chainsaws
can also be activated by inertia. See the
chapter entitled “Chain Brake” of your
Owner’s Manual.
No Quickstop or other chain brake
device prevents kickback. These devices
are designed to reduce the risk of
kickback injury, if activated, in certain
kickback situations. In order for the
Quickstop to reduce the risk of kickback
injury, it must be properly maintained
and in good working order. See the
chapter entitled “Chain Brake” and
“Maintenance, Repair and Storing” of
your Owner’s Manual. In addition, there
must be enough distance between the
bar and the operator to ensure that the
Quickstop has sufficient time to activate
and stop the chain before potential
contact with the operator.
An improperly maintained chain brake
may increase the time needed to stop
the chain after activation, or may not
activate at all.
Never run the chainsaw above idle
speed for more than 3 seconds when
the chain brake is engaged or the chain
is pinched or otherwise caught in the cut.
Clutch slippage can cause excessive
heat, leading to severe damage of the
motor housing, clutch and oiler component and may interfere with the operation
of the chain brake. If clutch slippage in
excess of 3 seconds has occured, allow
the motor housing to cool before proceeding and check the operation of your
chain brake as described in the chapter
entitled “Chain Brake”. Also make sure
that the chain is not turning at idle speed
(see above “Important Adjustments”).
STIHL offers a variety of bars and
chains. STIHL reduced kickback bars
and low kickback chains are designed to
reduce the risk of kickback injury. Other
chains are designed to obtain higher cutting efficiency or sharpening ease but
may result in higher kickback tendency.
STIHL has developed a color code
system to help you identify the STIHL
reduced kickback bars and low kickback chains. Cutting attachments with
green warning decals or green labels on
the packaging are designed to reduce
the risk of kickback injury. The matching
of green decaled powerheads under 3.8
cubic inch displacement with green
labeled bars and green labeled chains
gives compliance with the computed
kickback angle requirements of ANSI B
175.1-1991 when the products are in
their original condition. Products with
yellow decals or labels are for users with
extraordinary cutting needs and
experience and specialized training for
dealing with kickback.
Please ask your STlHL dealer to properly
match your powerhead with the appropriate bar/chain combinations to reduce
the risk of kickback injury. Green labeled
bars and chains are recommended for all
powerheads. See your “STIHL Bar and
Chain Information” leaflet for details.
Use of other, non-listed bar/chain combinations may increase kickback forces
and increase the risk of kickback injury.
New bar/chain combinations may be
developed after publication of this literature, which will, in combination with
certain powerheads, comply with § 5.11
of ANSI B 175.1-2000. Check with your
STIHL dealer for such combinations.
Reduced kickback bars and low kickback
chains do not prevent kickback, but they
are designed to reduce the risk of kickback injury. They are available from your
STIHL dealer.
Even if your saw is equipped with a
Quickstop, a reduced kickback bar
and/or low kickback chain, this does not
eliminate the risk of injury by kickback.
Therefore, always observe all safety
precautions to avoid kickback situations.
Some types of saw chain have specially
designed components to reduce the
force of nose contact kickback. STIHL
has developed low kickback chain for
your powerhead.
“Low kickback saw chain” is a chain
which has met the kickback performance
requirements of § of
ANSI B 175.1-2000 (Safety Requiree
ments for Gasoline-Powered ChainSaws) when tested in its original
condition on a selected representative sample of chainsaws below
3.8 cubic inch displacement specified in
ANSI B 175.1-2000.
There are potential powerhead and bar
combinations with which low kickback
saw chains can be used which have not
been specifically certified to comply with
the 45° computer derived kickback angle
of § 5.11 of ANSI B 175.1-2000.
Some low kickback chains have not
been tested with all powerhead and bar
A dull or improperly sharpened chain
may reduce or negate the effects of the
design features intended to reduce
kickback energy. Improper lowering or
sharpening of the depth gauges or
shaping of the cutters may increase the
chance and the potential energy of a
kickback. Always cut with a properly
sharpened chain.
STIHL green labeled reduced kickback
bars are designed to reduce the risk of
kickback injury when used with STIHL
green labeled low kickback chains.
When used with other, more aggressive
chains, these bars may be less effective
in reducing kickback, and may result in
higher kickback forces.
Do not mount a bow guide on any
STIHL chainsaw.
Any chainsaw equipped with a bow
guide is potentially very dangerous.
The risk of kickback is increased with a
bow guide because of the increased
kickback contact area. Low kickback
chain will not significantly reduce the risk
of kickback injury when used on a bow
The best protection from personal injury
that may result from kickback is to avoid
kickback situations:
1. Hold the chainsaw firmly with both
hands and maintain a secure grip.
2. Be aware of the location of the guide
bar nose at all times.
3. Never let the nose of the guide bar
contact any object. Do not cut limbs
with the nose of the guide bar.
Be especially careful when cutting
small, tough limbs, small size brush
and saplings which may easily catch
the chain.
4 Don’t overreach.
5. Don’t cut above shoulder height.
6. Begin cutting and continue at full
7. Cut only one log at a time.
8. Use extreme caution when reentering
a previous cut.
9. Do not attempt to plunge cut if you
are not experienced with these
cutting techniques.
10. Be alert for shifting of the log or other
forces that may cause the cut to
close and pinch the chain.
11. Maintain saw chain properly. Cut with
a correctly sharpened, properly
tensioned chain at all times.
12. Stand to the side of the cutting path
of the chainsaw.

Felling is cutting down a tree.
Before felling a tree, consider carefully all
conditions which may affect the direction
of fall, including:
The intended direction of the fall.
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The reaction
of the chain pulls the saw forward and
may cause the operator to lose control.
Pushback occurs when the chain on the
top of the bar is suddenly stopped when
it is pinched, caught or encounters a
foreign object in the wood. The reaction
of the chain drives the saw straight back
toward the operator and may cause loss
of saw control. Pushback frequently
occurs when the top of the bar is used for
The natural lean of the tree.
Pull-in frequently occurs when the
bumper spike of the saw is not held
securely against the tree or limb and
when the chain is not rotating at full
speed before it contacts the wood.
Use extreme caution when cutting small
size brush and saplings which may easily
catch the chain and pull you off balance.
1. Always start a cut with the chain
rotating at full speed and the bumper
spike in contact with the wood.
2. Pull-in may also be prevented by using
wedges to open the kerf or cut.
Any unusually heavy limb structure.
Surrounding trees and obstacles.
The wind direction and speed.
Always observe the general condition of
the tree. Inexperienced users should
never attempt to cut trees which are
decayed or rotted inside or which are
leaning or otherwise under tension.
Do not cut more than one log at a time. There is an increased risk that such trees
could snap or split while being cut and

least 21/2 tree lengths from the nearest
When felling in the vicinity of roads,
railways and power lines, etc., take extra
precautions. Inform the police, utility
company or railway authority before
beginning to cut.
The noise of your engine may drown any
warning call.
First clear the tree base and work area
from interfering limbs and brush and
clean its lower portion with an ax.
If the tree has large buttress roots, cut
into the largest buttress vertically first
(horizontally next) and remove the
resulting piece.
There are a number of factors that may
affect and change the intended direction
of fall, e.g. wind, lean of tree, sloping
ground, one-sided limb structure, wood
structure, decay, snow load, etc. To reduce the risk of severe or fatal injury to
yourself or others, look for these conditions prior to beginning the cut, and be
alert for a change in direction during fall.
Then, establish two paths of escape (%)
and remove all obstacles. These paths
should be generally opposite to the planned direction of the fall of the tree ($)
and about at a 45° angle. Place all
tools and equipment a safe distance away
from the tree, but not on the escape paths.

Helps control the falling tree
Do not cut through the hinge you could lose control of the
direction of the fall
In order to reduce the risk of personal
injury, never stand directly behind the
tree when it is about to fall, since part of
the trunk may split and come back
towards the operator (barber-chairing),
or the tree may jump backwards off the
stump. Always keep to the side of the
falling tree. When the tree starts to fall,
withdraw the bar, shut off the engine and
walk away on the preplanned escape
path. Watch out for falling limbs.
Be extremely careful with partially fallen
trees which are poorly supported.
When the tree hangs or for some other
reason does not fall completely, set the
saw aside and pull the tree down with a
cable winch, block and tackle or tractor.
If you try to cut it down with your saw,
you may be injured.
Engage the bumper spikes of the chainsaw directly behind the location of the
intended hinge and pivot the saw around
this point only as far as the hinge. The
bumper spike rolls against the trunk.
Felling a tree that has a diameter greater
than the length of the guide bar requires
use of either the sectioning felling cut or
plunge-cut method. These methods are
extremely dangerous because they
involve the use of the nose of the guide
bar and can result in kickback. Only
properly trained professionals should
attempt these techniques.
For the sectioning method make the first
part of the felling cut with the guide bar
fanning in toward the hinge. Then, using
the bumper spike as a pivot, reposition
the saw for the next cut.
001BA048 LÄ
001BA047 LÄ
001BA046 LÄ
Avoid repositioning the saw more than
necessary. When repositioning for the
next cut, keep the guide bar fully engaged
in the kerf to keep the felling cut straight.
If the saw begins to pinch, insert a
wedge to open the cut. On the last cut,
do not cut the hinge.
Timber having a diameter more than
twice the length of the guide bar requires
the use of the plunge-cut method before
making the felling cut.
First, cut a large, wide felling notch.
Make a plunge cut in the center of the
The plunge cut is made with the guide
bar nose. Begin the plunge cut by
applying the lower portion of the guide
bar nose to the tree at an angle. Cut until
the depth of the kerf is about the same as
the width of the guide bar. Next, align
the saw in the direction in which the
recess is to be cut.
With the saw at full throttle, insert the
guide bar in the trunk.
Enlarge the plunge cut as shown in
There is an extreme danger of kickback
at this point. Extra caution must be taken
to maintain control of the saw. To make
the felling cut, follow the sectioning
method described previously.
Limbing is removing the branches from
a fallen tree.
There is an extreme danger of kickback
during the limbing operation. Do not
work with the nose of the bar. Be extremely
cautious and avoid contacting the log or
other limbs with the nose of the guide bar.
001BA033 LÄ
001BA089 LÄ
If you are inexperienced with a chainsaw,
plunge-cutting should not be attempted.
Seek the help of a professional.
Do not stand on a log while limbing it –
you may slip or the log may roll.
Start limbing by leaving the lower limbs to
support the log off the ground. When
underbucking freely hanging limbs,
a pinch may result or the limb may fall,
causing loss of control. If a pinch occurs,
stop the engine and remove the saw,
by lifting the limb.
Be extremely cautious when cutting
limbs or logs under tension (spring poles).
The limbs or logs could spring back
toward the operator and cause loss of
control of the saw and severe or fatal
injury to the operator.
Bucking is cutting a log into sections.
When bucking, do not stand on the
log. Make sure the log will not roll
downhill. If on a slope, stand on the
uphill side of the log.
Watch out for rolling logs.
Cut only one log at a time.
Shattered wood should be cut very
carefully. Sharp slivers of wood
may be caught and flung in the
direction of the operator of the saw.
When cutting small logs, place log
through “V” - shaped supports on
top of a sawhorse. Never permit
another person to hold the log.
Never hold the log with your leg or

Logs under strain: Risk of pinching!
Always start relieving cut () at
compression side ($).
Then make bucking cut () at
tension side (%).
If the saw pinches, stop the engine
and remove it from the log.
Only properly trained professionals
should work in an area where the
logs, limbs and roots are tangled.
Working in blowdown areas is
extremely hazardous.
Drag the logs into a clear area before
cutting. Pull out exposed and cleared
logs first.
Never operate a chainsaw that is
damaged, improperly adjusted or not
completely or securely assembled.
Follow the maintenance and repair
instructions in the appropriate section of
your Owner’s Manual, especially those
in the chapters “Mounting the Bar and
Chain”, “Maintaining and Sharpening”
and “Chain Brake”.
Use only STIHL replacement parts for
maintenance and repair. Use of parts
manufactured by others may cause
serious or fatal injury.
Always stop the engine and ensure that
the chain is stopped before making any
adjustments, maintenance or repair work,
changing the saw chain or cleaning the
saw. Do not attempt any maintenance or
repair work not described in your
Owner’s Manual. Have such work performed at your STIHL service shop only.
Never test the ignition system with
ignition wire terminal removed from spark
plug or with unseated spark plug, since
uncontained sparking may cause a fire.
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug terminal of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug terminal and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire. Keep spark plug clean, and
make sure ignition lead is in good
Do not operate your chainsaw if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or burn will
result. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire (e. g. in the USA, Canada and
Australia), never operate your saw if the
screen is missing or damaged. Remember that the risk of forest fires is greater
in hot or dry weather.
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains.
Keep the chain sharp.
You can spot a dull chain when easy-tocut wood becomes hard to cut and burn
marks appear on the wood.
Keep the chain at proper tension. Tighten
all nuts, bolts and screws except the
carburetor adjustment screws after each
In order for the chain brake on your
STIHL chainsaw to properly perform its
function of reducing the risk of kickback
and other injuries, it must be properly
maintained. Like an automobile brake,
a chainsaw chain brake incurs wear
each time it is engaged.
The amount of wear will vary depending
upon usage, conditions under which the
saw is used and other factors. Excessive
wear will reduce the effectiveness of the
chain brake and can render it inoperable.
For the proper and effective operation of
the chain brake the brake band and
clutch drum must be kept free of dirt,
grease and other foreign matter which
may reduce friction of the band on the
For these reasons, each STIHL chainsaw should be returned to trained
personnel such as your STIHL servicing
dealer for periodic inspection and
servicing of the brake system according
to the following schedule:
Heavy usage - every three months,
Moderate usage - twice a year,
Occasional usage - annually.
The chainsaw should also be returned
immediately for maintenance whenever
the brake system cannot be thoroughly
cleaned or there is a change in its
operating characteristics.
For any maintenance please refer to the
maintenance chart DQGWRWKHZDUUDQW\
VWDWHPHQW near the end of this manual.
Additionally, the daily maintenance
schedule for your chainsaw set forth in
your STIHL Owner’s Manual should be
strictly followed.
Store chainsaw in a dry place and away
from children. Before storing for longer
than a few days, always empty the fuel
tank (see chapter "Storing the Machine"

This engine is certified to operate on
unleaded gasoline and oil with the
mix ratio 50:1.
Your two-stroke engine requires a
mixture of brand-name gasoline and
quality two-stroke engine oil with the
Use regular branded unleaded gasoline
with a minimum octane rating of
90 ROZ (U.S.A./Canada: pump octane
min. 89!). If the octane number of the
regular grade gasoline in your area is
lower, use premium unleaded fuel.
Fuel with a lower octane rating may
result in preignition (causing “pinging”)
which is accompanied by an increase in
engine temperature. This, in turn,
increases the risk of piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines etc.), but magnesium castings as
well. This could cause running problems
or even damage the engine. For this
reason it is essential that you use only
branded fuels!
Use only STIHL two-stroke engine oil or
equivalent branded two-stroke aircooled engine oils with the classification

Before starting work: Run engine at
idle speed, engage the chain brake

1RWHAlways disengage chain brake
before accelerating engine and before
starting cutting work. The only exception
to this rule is when you check operation
of the chain brake. High revs with the
chain brake engaged (chain locked) will
quickly damage the powerhead and
chain drive (clutch, chain brake).
The chain brake is subject to normal
wear and tear. It must therefore be
checked and serviced regularly by
trained personnel (e.g. STIHL dealer) at
the following intervals:
Full-time professional
every 3 months
every 6 months
every 12 months
A factory new machine should not be
run at high revs (full throttle off load)
for the first three tank fillings. This avoids
unnecessary high loads during the
break-in period.
A new chain has to be retensioned more
often than one that has been in use for
some time.
As all moving parts have to bed in
during the break-in period, the frictional
resistances in the engine are greater
during this period. The engine develops
its maximum power after about 5 to 15
tank fillings.
1RWH Always disengage chain brake
before accelerating engine and before
starting cutting work. High revs with the

Tension is correct when chain fits snugly
against the underside of the bar and can
still be pulled along the bar by hand.
Retension if necessary see section "Tensioning the Saw Chain".
Slacken off the chain if you have retensioned it at

cutting work.
The chain contracts as it cools down.
If it is not slackened off, it could damage
the crankshaft and bearings.

Retension the chain see section "Tensioning the Saw Chain".
Always slacken off the chain after
finishing work.
The chain contracts as it cools down.
If it is not slackened off, it can damage
the crankshaft and bearings.
Allow engine to run for a short while
at idling speed so that engine heat can
be dissipated by flow of cooling air.
This protects engine-mounted components (ignition, carburetor) from thermal

You can hold the saw in one of two ways for starting:
Hold the rear handle tightly between your legs, just
above the knees. Grip the front handle () securely
with your left hand.
Pull starter grip slowly with your right hand until
you feel the starter engage and then give it a quick,
strong pull. Do not pull out starter rope more than
70 cm (27.5 in) as it might otherwise break.
Do not allow starter grip to snap back. Guide it
back slowly so that starter rope can rewind correctly.

Hold the saw firmly on the ground with your left hand
on the front handle ().
Pull starter rope three or four times, then move choke

cranking it over, immediately open the choke. Then
continue cranking.

The choke lever is mechanically connected to the carburetor’s choke valve. The choke valve is closed when the choke
lever is on I and open when the choke lever is moved away
from I.
125BA021 LA
Disengage the chain brake before starting cutting work
by pulling the hand guard back toward the handlebar .
The engine is shut down by sliding the stop switch to G.
When starting a cold engine only keep the choke slide in the
I position until the engine begins to fire. Even if you do not
hear the engine firing, always open the choke after pulling
the starter rope three or four times. If you leave the choke
slide in the I position, the combustion chamber will flood
and stall the engine.
If you have moved the choke slide away from I after the
engine has fired or after three or four pulls on the starter
rope and the engine still refuses to start, you can assume
that the combustion chamber is already flooded. In such a
case, remove and dry off the spark plug. With the spark plug
still removed and the stop switch on G, clear the combustion chamber by cranking the engine several times on the
starter. When you now try to start, move the choke lever
away from I and set the throttle trigger to the start position.
The stop switch should again be moved away from G.
In very cold weather only open the choke partially after the
engine begins to fire – move choke lever to about the center
position. Allow engine to warm up for a brief period with the
throttle in the start position. Then move choke lever completely away from I and disengage the starting throttle
A new engine or one which has been run until the fuel tank
is dry will not start first time after fueling because the fuel
pump only begins to deliver sufficient fuel of the carburetor

Checking chain lubrication
A minimum bar groove depth must be maintained in order
to prevent the drive links contacting the bottom of the groove
(the heels of the cutter and tie strap would no longer on the
guide bar rails). The groove depth varies according to chain
type and pitch:
Chain type
Chain pitch
Minumum depth
3/8 "
5 mm (0.2")
The groove depth should be measured at the point where
the bar is stressed most. That is the bar nose on Duromatic
bars and the area where most of the cutting is done in
Rollomatic bars. The guide bar must be replaced when
groove depth is less than the specified minimum.
On Rollomatic guide bars it is not necessary to separately
lubricate the sprocket nose bearing because the chain oil
which flows to the bearing by way of the bar groove during
normal operation is adequate for lubrication.
125BA022 LA
The nose and underside of the guide bar are subject to a
particularly high rate of wear. To avoid one-sided wear, turn
the bar over every time you resharpen or preplace the chain.
Regular cleaning of the oil inlet holes and guide bar groove
is also important. The bar can be examined for signs of wear
at the same time.
Every new chain has to be broken in for about 2 to 3 minutes.
Ample chain lubrication is essential during this period. After
breaking in, stop the engine, check chain tension and adjust
if necessary.
Never operate the chain saw without proper chain lubrication. If the chain is allowed to run dry the whole cutting
attachment will be irretrievably damaged within a very short
time. For this reason you should always check operation of
the chain lubrication system and the level in the oil tank
before starting work.
Start the saw and hold the cutting attachment over a light
patch of ground. Take care – the Oilomatic chain must not
touch the ground; hold it at least 20 cm (8 in) clear of the
ground. Run the engine at about half throttle. If an increasing
film of oil can be seen on the ground, chain lubrication is
operating correctly. If this is not the case, refer to "Troubleshooting on Chain Oiling System".
Worn chain sprocket
As it warms up to normal operating temperature the chain
expands and sags noticeably. The saw chain must be
retensioned when the drive links begin to come out of the
groove on the underside of the bar. If this is not done, there
is a risk of the chain jumping off the bar.
If the chain is retensioned during cutting work it must always
be slackened off again after finishing work. This is necessary because high contraction stresses would otherwise
occur as the chain cools down to ambient temperature,
especially at extremely low outside temperatures, and
cause damage to the crankshaft and bearings.
A new chain must be retensioned more frequently than a
used one because it stretches during the initial break-in
125BA023 LA
Apart from chain lubrication, chain tension is the factor that
has the greatest influence of the cutting attachment’s useful
life. It is therefore necessary to check chain tension before
starting work and at regular short intervals during cutting
work. Chain tension is correct in the cold condition when the
chain fits snugly against the underside of the bar and can
still be pulled along the bar by hand (wear gloves!).
The stress and strain on the chain sprocket are particularly
high. If the wear marks on the teeth are very pronounced
(about 0.5 mm/0.02 in deep), the sprocket should be
replaced. A worn sprocket reduces the service life of the
saw chain. The chain sprocket should be replaced as a
matter of routine with every second Oilomatic chain. It is
best to use saw chains alternately with one sprocket.
Removing oil pump
Component parts of oil pump in correct sequence
125BA024 LA
If you have checked chain lubrication (see chapter "Guide
Bar, Saw Chain and Chain Sprocket") and found that no oil
is being delivered although the oil tank is full, switch off the
engine and start looking for the fault on the cutting attachment.
To do this, remove the chain sprocket cover, guide bar
and chain. Thoroughly clean the oil inlet holes as well
as the passage between the holes and the bar groove. Also
clean away dirt that may have collected at the end of the oil
hose and the area around it.
Now check oil delivery again. If no oil emerges from
the hose , the oil pump must be removed from the
machine and cleaned.
125BA025 LA
Drain the chain oil tank. Remove the fastening screws and withdraw the oil pump.
If the oil pump is stuck, use a screwdriver to carefully pry it
away from the crankcase.
Pull off the hose and remove the polymere disc . Take
the filter off the stub. Now pull the cover off the pump
housing, making sure that the diaphragm does not stick
to the cover and tear.
Take the plunger and diaphragm out of the pump
housing and remove the two gaskets Note the
spring between the pump housing and diaphragm. It
must not be lost.
Carefully wash the pump housing, cover, plunger with diaphragm and the filter in clean gasoline. Thoroughly clean
the gaskets and flange faces on the crankcase.
Reassemble the pump by reversing the above sequence.
Coat the plunger with a little lubricating oil before refitting.
Unscrewing the flat head screw
Filter cover removed
The air filter’s function is to hold back dust and dirt in the
intake air and thus reduce wear on engine components to
a minimum.
125BA026 LA
Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult.
Before removing the filter, clean loose dirt off the filter
cover and the area around it to be sure that no dirt can
get into the engine through the carburetor when the cover
is removed.
The intake air flows to the underside of the filter element. It
follows that only the underside of the element becomes
dirty. It is therefore necessary to remove the element and
turn it over to check its condition.
To clean the element, first knock it out on the palm of your
hand and then wash it in non-flammable cleaning solution
(warm soapy water) and blow out with compressed air if
possible. It is best to carry a spare filter with you at all times.
The element must be replaced immediately if the felt shows
any signs of damage (tears, holes).
125BA027 LA
Take out the M 4 flat head screw to remove the filter cover
and air filter element .
Refit the air filter by reversing the above sequence. When
placing the filter cover in position, make sure the lugs
engage in the recesses in the crankcase. Also make sure
that the choke valve in the filter cover is in good condition.
It is usually necessary to change the
setting of the idle speed adjusting screw
/$ after every correction to the low
speed screw /.
Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components
(e.g. carburetion, ignition, timing and
valve or port timing) without the addition
of any major hardware.
Turn the idle speed adjusting screw
/$ clockwise
until chain begins to run then back off the screw one quarter
of a turn.
Turn the idle speed adjusting screw
/$ counterclockwise until chain
stops running then turn screw another quarter
turn in the same direction.
Check the air filter and clean it if
Warm up the engine.
Turn screws only very slightly and
carefully - even minor changes
have a noticeable effect on the
engine’s running behavior.
Idle setting is too lean.
Turn the low speed adjusting screw
/ counterclockwise until engine
runs and accelerates smoothly.
Use only resistor type spark plugs
of the approved range.
Rectify problems which have caused
fouling of spark plug:
Incorrect carburetor setting, too much oil
in fuel mix, dirty air filter,
unfavorable running conditions, e.g.
operating at part load.
Fit a new spark plug after
approx. 100 operating hours –
or earlier if the electrodes are
badly eroded.
Wrong fuel mix (too much engine oil in
the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition of
the spark plug. These factors cause
deposits to form on the insulator nose
which may result in trouble in operation.
If engine is down on power, difficult to
start or runs poorly at idling speed,
first check the spark plug.
Remove spark plug –
see chapter “Starting”:
Clean dirty spark plug.
Check electrode gap –
it should be 0.5mm/0.02" $ –
readjust if necessary.
000BA036 TR
000BA002 KN
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL (see “Specifications”). Always
press spark plug boot snugly onto
spark plug terminal of the proper
size. (Note: If terminal has detachable
SAE adapter nut, it must be attached.)
A loose connection between spark plug
terminal and ignition wire connector in
the boot may create arcing that could
ignite combustible fumes and cause a
Locking screw in position
Removing the clutch
Parts in correct order
First disengage the chain brake (pull hand guard back
toward front handle) and then remove the chain sprocket
cover, guide bar and chain.
Turn clutch to rotate crankshaft clockwise until the piston
head butts against the lockig srew. Now use a suitable
19-mm wrench to unscrew the clutch.
125BA028 LA
Take out the spark plug and screw locking screw into
spark plug hole by hand until it is firmly seated.
125BA029 LA
After unscrewing the clutch, remove the chain sprocket and
needle cage from the crankshaft. Clean the stub of the
crankshaft. Wash out needle cage in clean gasoline and
lubricate it with anti-friction bearing grease.
Examine clutch shoes , springs , retainers and
clutch carrier for cracks. If any damage is found, replace
the parts concerned.
Reverse the above sequence to refit the parts. Take care to
ensure that the clutch shoes and retainers are correctly
positioned. Securely tighten down the clutch again.
Remove the locking srew, refit and tighten down the spark
plug. Fit the spark plug connector.
125BA030 LA
Only original STIHL chain sprockets may be installed.
Maintaining and Sharpening
Saw Chain
Correctly sharpened chain
Clean and check your chain
for cracks in the links and damaged
rivets – replace any damaged or worn
parts of the chain and match the new
parts to the shape and size of the
original parts.
It is absolutely essential to comply
with the angles and dimensions
specified below. If the saw chain is
incorrectly sharpened – and in
particular if the depth gauge is set
too low – there is a risk of increased
kickback of the chainsaw, with
resulting risk of injury.
Select sharpening tools according
to chain pitch.
See “Specifications” for permissible
chain pitches.
689BA020 KN
Do not work with a dull or damaged
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.
The chain pitch (e.g. 3/8") is marked on
the depth gauge end of each cutter.
Use only special saw chain
sharpening files. Other files have the
wrong shape and cut.
Select file diameter according to chain
pitch – see table “Sharpening Tools” at
the end of this chapter.
You must observe certain angles when
resharpening the chain cutter.
689BA021 KN
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
A = Filing angle
B = Side plate angle
Chain type
Rapid-Micro (RM)
Rapid-Super (RS)
Picco-Micro (PM/PMN)
Angle (°)
Cutter shapes:
Micro = Semi-chisel
Super = Full chisel
The specified angles A and B are
obtained automatically if recommended
files or sharpening tools and correct
settings are used.
689BA025 KN
As these requirements can be met only
after sufficient and constant practice:
Special Accessory
For checking angles
File correctly
STlHL filing gauge* (see table).
A universal tool for checking the filing
and side plate angles, depth gauge
setting and cutter length. Also cleans the
guide bar groove and oil inlet hole.
If you use a file holder, the FG 1 or
FG 3:
Leave the chain on the bar.
Clamp the bar in a vise if necessary.
Lock the chain – push hand guard
To rotate the chain – pull hand guard
against handle.
Sharpen chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
Always file from the inside to the
outside of the cutter.
The file only sharpens on the
forward stroke –
lift the file off the cutter on the
: Use a file holder*
A file holder must be used for manual
resharpening of Super chain. The
correct filing angle is marked on the file
689BA018 KN
85° 70° 60°
689BA022 KN
Furthermore, the angles must be the
same on all cutters. If angles are
uneven: Chain will run roughly, not in a
straight line, wear quickly and finally
Special Accessory
Avoid touching the tie straps and
drive links with the file.
Rotate the file at regular intervals
while filing to avoid one-sided wear.
Use a piece of hardwood to remove
burrs from cutting edge.
Check angles with the filing gauge.
All cutters must be the same length.
If the cutters are not the same length,
they will have different heights. This
makes the chain run roughly and can
cause it to break.
Find the shortest cutter and then file all
other cutters back to the same length.
This can be very time consuming – it is
best to have it done in the workshop on
an electric grinder.
The depth gauge setting is reduced
when the chain is sharpened. Use filing
gauge to check the setting every time
you sharpen the chain and, if necessary,
lower the depth gauge with a flat or
triangular file so that it is level with the
filing gauge.
Depth gauge setting
The depth gauge determines the height
at which the cutter enters the wood and
thus the thickness of the chip removed.
Specificed distance or setting between
depth gauge and cutting edge = a:
This setting may be increased by 0.2mm
(0.008") for cutting softwood in mild
weather season – no frost.

Hold the file horizontally for all
chain types (at right angle to side of
guide bar) and file according to the
angles marked on the filing tool.
689BA023 KN
Round off depth gauges parallel to the
stamped marking.
After sharpening
Clean the chain thoroughly, remove
filings or grinding dust – lubricate the
chain by immersing it in an oil bath.
