Safety Precautions and
Working Techniques
Because a pole pruner is
a high-speed, fast-cutting
power tool with a very
long reach, special safety
precautions must be
observed to reduce the
risk of personal injury.
It is important that you
read, fully understand and
observe the following
safety precautions and
warnings. Read the
instruction manual and
the safety precautions periodically.
Careless or improper use may cause
serious or fatal injury.
Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable local safety regulations,
standards and ordinances.
!Warning!
Do not lend or rent your power tool
without the instruction manual. Be sure
that anyone using it understands the
information contained in this manual.
!Warning!
The use of this machine may be
hazardous. The pole pruner chain has
many sharp cutters. If the cutters contact
your flesh, they will cut you, even if the
chain is not moving.
HT 100, HT 101, HT 130, HT 131
Do not cut any material other than wood
or wooden objects. Use your pole pruner
for limbing only. It must not be used for
any other purposes, since such misuse
may result in an accident or damage to
the machine.
!Warning!
Minors should never be allowed to use
this power tool. Bystanders, especially
children, and animals should not be
allowed in the area where it is in use.
!Warning!
To reduce the risk of injury to bystanders
and damage to property, never let your
power tool run unattended. When it is
not in use (e.g. during a work break),
shut it off and make sure that
unauthorized persons do not use it.
THE OPERATOR
Physical Condition
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol, etc.) which might impair vision,
dexterity or judgment. Do not operate
this machine when you are fatigued.
!Warning!
Be alert – if you get tired, take a break.
Tiredness may result in loss of control.
Working with any power tool can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
this machine.
Most of these safety precautions and
warnings apply to the use of all STIHL
pole pruners. Different models may have
different parts and controls. See the
appropriate section of your instruction
manual for a description of the controls
and the function of the parts of your
model.
Safe use of a pole pruner involves

English / USA
!Warning!
Prolonged use of a power tool (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:
Most STIHL power tools are available
with an anti-vibration (“AV”) system
designed to reduce the transmission of
vibrations created by the machine to the
operator's hands. An AV system is
recommended for those persons using
power tools on a regular or sustained
basis.
Keep the AV system well maintained. A
power tool with loose components or
with damaged or worn AV buffers will
tend to have higher vibration levels.
Maintain a firm grip at all times, but do
not squeeze the handles with constant,
excessive pressure. 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 closely monitor the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.
!Warning!
The ignition system of the STIHL unit
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce the risk of serious or fatal injury,
persons with a pacemaker should
consult their physician and the
pacemaker manufacturer before
operating this tool.
Proper Clothing
!Warning!
To reduce the risk of injury, the operator
should wear proper protective apparel.
!Warning!
To reduce the risk of injury
to your eyes never
operate your power tool
unless wearing goggles or
properly fitted protective
glasses with adequate top
and side protection complying with ANSI
Z 87.1 (or your applicable national
standard). To reduce the risk of injury to
your face STIHL recommends that you
also wear a face shield or face screen
over your goggles or protective glasses.
Wear an approved safety hard hat to
reduce the risk of injury to your head.
Power tool noise may damage your
hearing. Wear sound barriers (ear plugs
or ear mufflers) to protect your hearing.
Continual and regular users should have
their hearing checked regularly.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Wear gloves and keep your hands
warm.

HT 100, HT 101, HT 130, HT 131
English / USA
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs. Do not wear shorts, sandals
or go barefoot.
Avoid loose-fitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become caught on branches,
brush or the moving parts of the unit.
Secure hair so it is above shoulder level.
Good footing is very
important. Wear sturdy
boots with nonslip soles.
Steel-toed safety boots
with cut retardant inserts
are recommended.

THE POWER TOOL
THE USE OF THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
“Main Parts and Controls.”
Transporting the Power Tool
!Warning!
!Warning!
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may, in
fact, be extremely dangerous.
If this tool is subjected to unusually high
loads for which it was not designed (e.g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
390BA000 KN
Always wear gloves when
handling the machine and
the cutting tool. Heavyduty, nonslip gloves
improve your grip and
help to protect your
hands.
This power tool should be carried only in
a horizontal position. Grip the shaft in a
manner that the machine is balanced
horizontally. Keep the hot muffler away
from your body and the cutting
attachment behind you. Accidental
acceleration of the engine can cause the
chain to rotate and cause serious
injuries.
!Warning!
Always switch off the engine and fit the
scabbard over the cutting attachment
before transporting the power tool over
long distances. When transporting it in a
vehicle, properly secure it to prevent
turnover, fuel spillage and damage to the
unit.
5
English / USA
Fuel
Your STIHL power tool uses an oilgasoline mixture for fuel (see the chapter on “Fuel” of your instruction manual).
!Warning!
Gasoline is an extremely
flammable fuel. If spilled
and 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 power tool. Note that
combustible fuel vapor may escape from
the fuel system.
Select bare ground for fueling and move
at least 10 feet (3 m) from the fueling
spot before starting the engine. Wipe off
any spilled fuel before starting your
machine.
!Warning!
Check for fuel leakage while refueling
and during operation. If fuel leakage is
found, do not start or run the engine until
the leak is fixed and any 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 be equipped with
different fuel caps.
Cap with grip
Fueling Instructions
!Warning!
Fuel your power tool in well-ventilated
areas, outdoors. Always shut off the
engine and allow it to cool before
refueling. Gasoline vapor pressure may
build up inside the fuel tank depending
on the fuel used, the weather conditions
and the tank venting system.
In order to reduce the risk of burns and
other personal injury from escaping gas
vapor and fumes, remove the fuel filler
cap on your power tool carefully so as to
allow any pressure build-up in the tank
to release slowly. Never remove the fuel
filler cap while the engine is running.
6
!Warning!
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.
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 in 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.
Screw cap
!Warning!
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 the fuel filler cap
by hand as securely as possible.
HT 100, HT 101, HT 130, HT 131
English / USA
Take off the chain guard (scabbard) and
inspect the pole pruner for proper
condition and operation. (See the
maintenance chart near the end of the
instruction manual.)
!Warning!
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger interlock, stop switch and cutting
attachment. The throttle trigger must
move freely and always spring back to
the idle position. Never attempt to
modify the controls or safety devices.
!Warning!
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
!Warning!
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
Starting
!Warning
To reduce the risk of fire and burn
injuries, start the engine at least 10 feet
(3 meters) from the fueling spot,
outdoors only.
Start and operate your pole pruner
without assistance.
For specific starting instructions, see the
appropriate section of your manual.
Proper starting methods reduce the risk
of injury.
For proper assembly of the bar and
chain follow the procedure described in
the chapter “Mounting the Bar and
Chain“ of your instruction manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch.
!Warning!
Proper chain tension is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your
manual. Always make sure the hex
nut(s) for the sprocket cover is (are)
tightened securely after tensioning the
chain. Check chain tension once more
after having tightened the nut(s). Never
start the pole pruner with the sprocket
cover loose.
275BA006 KN
Before Starting
Place the pole pruner on firm ground or
other solid surface in an open area or, in
the alternative, as shown in the above
picture. Maintain good balance and
secure footing.
Adjust carrying harness and hand grip to
suit your size before starting work.
HT 100, HT 101, HT 130, HT 131

English / USA
To reduce the risk of injury from loss of
control, do not attempt to “drop start”
your power tool.
!Warning!
To reduce the risk of injury from loss of
control be absolutely sure that the guide
bar and chain are clear of you and all
other obstructions and objects, including
the ground, because when the engine
starts at starting-throttle, engine speed
will be fast enough for the clutch to
engage the sprocket and turn the chain.
Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to idle
With the engine running only at idle,
attach the power tool to the spring hook
of your harness (see appropriate
chapter of this manual).
!Warning!
When you pull the starter grip, do not
wrap the starter rope around your hand.
Do not let the grip snap back, but guide
the starter rope to rewind it properly.
Failure to follow this procedure may
result in injury to your hand or fingers
and may damage the starter
mechanism.
8
Important Adjustments
During Operation
!Warning!
Holding and controlling the power
tool
To reduce the risk of personal injury from
loss of control or contact with the
running cutting tool, do not use your unit
with incorrect idle adjustment. At correct
idle speed, the saw chain should not
move. For directions on how to adjust
idle speed, see the appropriate section
of your instruction manual.
Always hold the unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
around the handles.
If you cannot set the correct idle speed,
have your STIHL dealer check your
power tool and make proper
adjustments and repairs.
Proper chain tension is very important at
all times. Check it at regular intervals
(whenever the pole pruner is shut off). If
the chain becomes loose while cutting,
switch off the engine and then tighten.
Never try to tighten the chain while the
engine is running.
390BA026 KN
!Warning!
Place your left hand on the shaft and
your right hand on rear grip and throttle
trigger. Left handers should follow these
instructions too. Keep your hands in this
position to have your pole pruner under
control at all times.
HT 100, HT 101, HT 130, HT 131
English / USA
!Warning!
!Warning!
!Warning!
Never attempt to operate your power
tool with one hand. Loss of control of the
power tool resulting in serious or fatal
injury may result.
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.
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work
practices, such as always cutting with a
properly sharpened chain (which
produces wood chips rather than fine
dust) and operating the unit so that the
wind or operating process directs any
dust raised by the power tool away from
the operator. Follow the
recommendations of EPA/OSHA/
NIOSH and occupational and trade
associations with respect to dust
(“particulate matter”). When the
inhalation of dust cannot be substantially
controlled, i.e., kept at or near the
ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH/
MSHA for the type of dust encountered.
!Warning!
In order to properly control your pole
pruner, always maintain good balance
and a firm foothold. Never work on a
ladder, in a tree or on any other insecure
support. Never hold the machine above
shoulder height. Do not overreach.
When working at a height above 15 feet
(4.5 m) use a lift bucket. For pole pruner
with adjustable shaft, expand the shaft
only as far as necessary for the intended
application.
!Warning!
Special care must be taken in slippery
conditions (wet ground, snow) and in
difficult, overgrown terrain. Watch for
hidden obstacles such as tree stumps,
roots, rocks, holes and ditches to avoid
stumbling. For better footing, clear away
fallen branches, scrub and cuttings. Be
extremely cautious when working on
slopes or uneven ground.
HT 100, HT 101, HT 130, HT 131
Working conditions
Operate and start your power tool only
outdoors in a well ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
!Warning!
As soon as the engine is
running, this product
generates toxic exhaust
fumes containing
chemicals, such as
unburned hydrocarbons
(including benzene) and carbon
monoxide, that are known to cause
respiratory problems, cancer, birth
defects, or other reproductive harm.
Some of the gases (e.g. carbon
monoxide) may be colorless and
odorless. To reduce the risk of serious or
fatal injury/illness from inhaling toxic
fumes, never run the machine indoors or
in poorly ventilated locations. If exhaust
fumes become concentrated due to
insufficient ventilation, clear
obstructions from work area to permit
proper ventilation before proceeding
and/or take frequent breaks to allow
fumes to dissipate before they become
concentrated.

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. If you have any reason to
believe that you might be cutting
asbestos, immediately contact your
employer or a local OSHA
representative.
In the event of an emergency, switch off
the engine immediately – move the slide
control / stop switch to 0 or STOP.
15m (50ft)
!Warning
This power tool has a large range. In
order to reduce the risk of personal or
even fatal injury to bystanders from
falling objects or inadvertent contact with
the moving chain of your power tool
always keep bystanders at least 50 feet
(15m) away when the power tool is
running.
!Warning!
Even though bystanders should be kept
away from the running saw, never work
alone. Keep within calling distance of
others in case help is needed.
Stop the engine immediately if you are
approached.
10
Danger!
Your power tool is not
insulated against electric
shock. To reduce the risk
of electrocution, never
operate this power tool in the vicinity of
any wires or cables (power, etc.) which
may be carrying electric current.
Electricity can jump from one point to
another by means of arcing. Higher
voltage increases the distance electricity
can arc. Electricity can also move
through branches, especially if they are
wet. Maintain a clearance of at least
50 feet (15 m) between the pole pruner
(including any branches it is contacting)
and any electrical line carrying live
current. Before working with less
clearance, contact your electric utility
and make sure the current is turned off.
!Warning
To reduce the risk of cut injuries, keep
hands and feet away from the saw
chain. Never touch a moving chain with
your hand or any other part of your body.
The saw chain continues to move for a
short period after the throttle trigger is
released (inertia effect).
Accelerating the engine while the chain
is blocked increases the load and will
cause the clutch to slip continuously.
This may result in overheating and
damage to important components (e.g.
clutch, polymer housing components) –
which can then increase the risk of injury
from the chain moving while the engine
is idling.
!Warning!
If the chain becomes clogged, always
turn off the engine and make sure the
chain has stopped before cleaning.
HT 100, HT 101, HT 130, HT 131
English / USA
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 and injure the
operator or bystanders, or damage the
saw chain.
Watch for falling wood! As soon as the
limbed branch starts to fall, step aside
and keep a sufficient distance away from
the falling wood.
!Warning!
Always pull the unit out of the cut with
the chain running to reduce the
possibility of pinching the cutting
attachment. Don't put pressure on the
pole pruner 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 some
other object.
!Warning
Prior to limbing, clear the working area
from interfering limbs and brush. Then,
establish an escape area away from
where the cut limbs can fall, and remove
all obstacles.
275BA005 KN
Keep work area clear – move away
fallen limbs. Place all tools and
equipment at a safe distance from the
branches being limbed, but not in the
escape area.
!Warning!
Always observe the general condition of
the tree. Look for decay and rot in the
trunk and branches. If it is rotted inside,
it could snap and fall toward the operator
while being cut. Also look for broken or
dead branches which could vibrate
loose and fall on the operator.
If branch is thick or heavy, make a
shallow relief cut on the bottom of the
branch before cutting down from the top
to help prevent splitting of the branch.
HT 100, HT 101, HT 130, HT 131
!Warning!
To reduce the risk of severe or even fatal
injury from falling objects do not cut
vertically above your body. Hold the pole
pruner at an angle of not more than 60°
from the horizontal level (see picture).
Objects may fall in unexpected
directions. Do not stand directly
underneath the limb being cut!
If the bar becomes pinched and caught
in the branch so that the chain can no
longer move, shut off the pole pruner
and carefully move the branch to open
the pinch and release the bar.
!Warning!
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.
11
English / USA
!Warning!
!Warning!
To reduce the risk of fire and burn injury,
keep the area around the muffler clean.
Remove excess lubricant and all debris
such as pine needles, branches or
leaves. Let the engine cool down sitting
on concrete, metal, bare ground or solid
wood (e.g. the trunk of a felled tree)
away from any combustible substances.
Since a muffler with a catalytic converter
cools down less rapidly than conventional mufflers, always set your power
tool down in the upright position and
never locate it where the muffler is near
dry brush, grass, wood chips or other
combustible materials while it is still hot.
!Warning!
Never modify your muffler. The muffler
could be damaged and cause an
increase in heat radiation or sparks,
thereby increasing the risk of fire and
burn injury. You may also permanently
damage the engine. Have your muffler
serviced and repaired by your STIHL
servicing dealer only.
Catalytic converter
!Warning!
Some STIHL power tools
are equipped with a
catalytic converter, which
is designed to reduce the
exhaust emissions of the
engine by a chemical
process in the muffler. Due to this
process, the muffler does not cool down
as rapidly as conventional mufflers when
the engine returns to idle or is shut off.
To reduce the risk of fire and burn
injuries, the following specific safety
precautions must be observed.
12
!Warning!
An improperly mounted or damaged
cylinder housing or a damaged/
deformed muffler shell may interfere
with the cooling process of the catalytic
converter. To reduce the risk of fire or
burn injury, do not continue work with a
damaged or improperly mounted
cylinder housing or a damaged/
deformed muffler shell.
Your catalytic converter is furnished with
screens designed to reduce the risk of
fire from the emission of hot particles.
Due to the heat from the catalytic
reaction, these screens will normally
stay clean and need no service or
maintenance. If you experience loss of
performance and you suspect a clogged
screen, have your muffler maintained by
a STIHL servicing dealer.
Reactive forces
!Warning!
Reactive forces may occur any time the
chain is rotating.The 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 such as a branch or is
pinched, the reactive forces may occur
instantly. These reactive forces may
result in loss of control, which, in turn,
may cause personal injury. An
understanding of the causes of these
reactive forces may help you avoid the
element of surprise and loss of control.
Because of the design of the pole
pruner, the reactive forces experienced
when working with it are generally not as
severe as those encountered with a
chainsaw. Nevertheless, you should
always maintain a proper grip and good
footing to control the power tool when
you experience such forces.
HT 100, HT 101, HT 130, HT 131

The most common reactive forces are:
To avoid kickback
To avoid pull-in
–
1.
Be alert to forces or situations that
may cause material to pinch the
chain at the bottom of the bar.
2.
Always start a cut with the chain
rotating at full speed
–
pushback,
The best protection from kickback is to
avoid kickback situations:
–
pull-in.
1.
2.
Kickback
Kickback may occur when the moving
saw chain near the upper quadrant of
the bar nose contacts a solid object or is
pinched.
3.
Be aware of the location of the guide
bar nose at all times.
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 near wire fences
and when cutting small, tough
limbs, which may easily catch the
chain.
B = Pushback
Cut only one limb at a time.
001BA038 KN
kickback,
A = Pull-in
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 cause the
bar to move upward.
A
001BA037 KN
002BA230 KN
B
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.
Pull-in frequently occurs when the chain
is not rotating at full speed before it
contacts the wood.
HT 100, HT 101, HT 130, HT 131
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 may drive the saw rapidly
straight back toward the operator.
Pushback frequently occurs when the
top of the bar is used for cutting.
To avoid pushback
1.
Be alert to forces or situations that
may cause material to pinch the
chain at the top of the bar.
2.
Do not cut more than one limb at a
time.
3.
Do not twist the bar when
withdrawing it from an underbuck
cut because the chain can pinch.

MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However, if you make a
warranty claim for a component
which has not been serviced or
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
!Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Strictly follow the maintenance and
repair instructions in the appropriate
sections of your instruction manual.
Please refer to the maintenance chart in
this manual.
!Warning!
Always stop the engine and make sure
that the chain is stopped before doing
any maintenance or repair work or
cleaning the power tool. Do not attempt
any maintenance or repair work not
described in your instruction manual.
Have such work performed by your
STIHL servicing dealer only.
!Warning!
!Warning!
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. 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 securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire.
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut or burn marks appear on the
wood.
!Warning!
Store the power tool in a dry and high or
locked location out of reach of children.
Never test the ignition system with the
ignition wire boot removed from the
spark plug or with a removed spark plug,
since uncontained sparking may cause
a fire.
!Warning!
Do not operate your power tool if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
If your muffler was equipped with a
spark-arresting screen to reduce the risk
of fire, never operate your power tool if
the screen is missing or damaged.
Remember that the risk of forest fires is
greater in hot or dry weather.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
For maintenance items please also refer
to the maintenance chart in this manual.
Before storing for longer than a few
days, always empty the fuel tank. See
chapter "Storing the machine" in this
manual.
Store fuel and chain oil in approved and
properly labeled safety-type canisters
only. Take care when handling gasoline!
Avoid direct contact with the skin and
avoid inhaling fuel vapor!
Wear gloves when handling or
performing maintenance on the cutting
attachment.

:
Wear suitable protective clothing
and equipment – see "Safety
Precautions".
:
Adjust telescopic shaft to the
required length (HT 101, HT 131
only)
Hold the control handle with your right
hand, and the shaft with your left hand.
Your left arm should be extended to the
most comfortable position.
:
Start the engine.
:
Put on the shoulder strap.
HT 100, HT 130:
Always hold the shaft with your left hand
in the area of the handle hose.
Cross-cut
390BA052 KN
Never throw cuttings into the
household garbage can – cutting
can be composted.
The most convenient working position is
a tool angle of 60°, but any lesser angle
may be used to suit the situation
concerned.
Never stand directly underneath the
branch you are cutting – be wary of
falling branches. Note that a branch
may spring back at you after it hits
the ground.
To avoid pinching the bar in the cut,
position the cutting attachment with the
hook against the branch and then
perform the cross-cut from the top
downwards.
Cutting sequence
390BA018 KN
To allow branches a free fall, always cut
the lower branches first. Prune heavy
branches (large diameter) in several
controllable pieces.
The shaft should always be held at an
angle of 60° or less.

Relieving cut
Flush-cutting thick branches
Cutting above obstacles
:
To avoid tearing the bark on thick
branches, always start by
performing a relieving cut (1) on the
underside of the branch.
:
:
To do this, apply the cutting
attachment and pull it across the
bottom of the branch as far as the
bar nose.
The unit's long reach makes it possible
to prune branches that are overhanging
obstacles, such as rivers or lakes. The
tool angle in this case depends on the
position of the branch.
:
Locate the hook against the branch
and then perform the cross-cut (2).
16
If branch diameter is more than 4"
(10 cm), first perform undercut (3)
and then cross-cut at a distance of
about 8" (20 cm) (A) from the final
cut.
Then carry out the flush-cut (4),
starting with a relieving cut and
finishing with a cross-cut.

4-MIX Engine
Fuel
The STIHL 4-MIX engine features gas
oil lubrication and must be run on a fuel
mixture of gasoline and engine oil.
This engine is certified to operate on
unleaded gasoline and the STIHL twostroke engine oil at a mix ratio of 50:1.
It operates otherwise on the 4-stroke
principle.
Your engine requires a mixture of highquality gasoline and quality two-stroke
air cooled engine oil.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 (R+M/2). If
the octane rating of the mid-grade
gasoline in your area is lower, use
premium unleaded fuel.
Fuel with a lower octane rating may
increase engine temperatures. 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 and
catalytic converters as well. This could
cause running problems or even
damage the engine. For this reason
STIHL recommends that you use only
nationally recognized high-quality
unleaded gasoline!
20
HT 100, HT 101, HT 130, HT 131
English / USA
Fueling
We recommend STIHL 50:1 two-stroke
engine oil since it is specially formulated
for use in STlHL engines.
Do not use BIA or TCW rated (twostroke water cooled) mix oils or other
mix oils that state they are for use in both
water cooled and air cooled engines
(e.g., outboard motors, snowmobiles,
chainsaws, mopeds, etc.).
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapor. When filling at
the pump, first remove the canister from
your vehicle and place the canister on
the ground before filling. Do not fill fuel
canisters that are sitting in or on a
vehicle.
The canister should be kept tightly
closed in order to avoid any moisture
getting into the mixture.
The machine‘s fuel tank and the canister
in which fuel mix is stored should be
cleaned as necessary.
HT 100, HT 101, HT 130, HT 131
Fuel mix ages
Only mix sufficient fuel for a few days
work, not to exceed 3 months of storage.
Store in approved fuel-canisters only.
When mixing, pour oil into the canister
first, and then add gasoline. Close the
canister and shake it vigorously by hand
to ensure proper mixing of the oil with
the fuel.

only in air cooled two-cycle engines.
Before fueling, clean the filler cap and
the area around it to ensure that no dirt
falls into the tank.
Always thoroughly shake the mixture in
the canister before fueling your
machine.
In order to reduce the risk of burns
or other personal injury from
escaping gas vapor and fumes,
remove the fuel filler cap carefully
so as to allow any pressure build-up
in the tank to release slowly.

Turn the cap clockwise as far as
stop (approx. a quarter turn).
Turn the cap counterclockwise
(approx. a quarter turn).
:
Remove the filler cap.
249BA056 KN
:
Biological chain oil must be resistant
to aging (e.g. STIHL BioPlus) since
it will otherwise quickly turn to resin.
This results in hard deposits that are
difficult to remove, especially in the
area of the chain drive and chain. It
may even cause the oil pump to
seize.
The service life of the chain and guide
bar depends on the quality of the
lubricant. It is therefore essential to use
only a specially formulated chain
lubricant.
249BA054 KN
:
For automatic and reliable
lubrication of the chain and guide
bar – use only an environmentally
compatible quality chain and bar
lubricant with non-fling additive
or the rapidly biodegradable
STIHL BioPlus is recommended.

A full chain oil tank is sufficient
for only half a tankful of fuel.
Check the oil level regularly
during cutting work. Never allow
the oil tank to run dry!
The bayonet-type oil tank filler cap with
its hinged grip can be opened and
closed without tools.
:
:
To open the tank, swing the grip (1)
to the vertical position.
Thoroughly clean the filler cap and
area around it so that no dirt can fall
into the tank.
:
Turn the filler cap counterclockwise
as far as stop and remove.
:
Position the unit so that the filler cap
faces up.

:
Waste oil does not have the
necessary lubricating properties
and is unsuitable for chain
lubrication.
If the oil level in the tank does not go
down, the reason may be a problem in
the oil supply system: Check chain
lubrication, clean the oilways, contact
your servicing dealer for assistance if
necessary. STIHL recommends that you
have maintenance and repair work
performed only by a STIHL servicing
dealer.

Operating Instructions
Throttle cable adjustment
During break-in period
:
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. 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.
Check adjustment of throttle cable –
see "Adjusting the Throttle Cable".
Tank run until dry
:
After refueling, press the fuel pump
bulb at least five times – even if bulb
is filled with fuel.
:
Set choke knob according to engine
temperature.
:
Now start the engine.
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see chapter "Adjusting the
Carburetor".
During operation
Check chain tension frequently!
A new chain has to be tensioned more
often than one that has been in use for
some time.
HT 100, HT 101, HT 130, HT 131
Cold chain
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand.
Retension if necessary –
see chapter "Tensioning the Saw
Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links on the underside of the
bar must not come out of the bar groove
– the chain may otherwise jump off the
bar.
Retension the chain –
see chapter "Tensioning the Saw
Chain".
Always slacken off the chain again
after finishing work. The chain
contracts as it cools down. If it is not
slackened off, it may damage the
crankshaft and bearings.
