Safety Precautions and
Working Techniques
Special safety precautions must be taken when
working with the cut-off
machine, due to the very
high rotational speed of
the abrasive wheel.
It is important you read
and understand the
Instruction Manual before
first use and keep the
manual in a safe place for
future reference. Nonobservance of the safety
instructions may result in
serious or even fatal
injury.
Comply with national safety regulations,
e.g. issued by employers' liability
insurance associations, social security
institutions, occupational safety and
health authorities or other organizations.
For employers within the European
Union, Directive 2009/104/EC is binding
– Minimum safety and health
requirements for the use of work
equipment by workers at work.
Anyone using the power tool for the first
time: Let the retailer or another expert
explain to you how to handle it safely –
or attend a training course.
Minors are not allowed to use the power
tool, except adolescents above 16 years
of age receiving instruction under
supervision.
Keep children, animals and bystanders
at a safe distance.

TS 410, TS 420
English
When the machine is not in use, put it
down safely so that it does not endanger
anyone. The machine must be secured
against unauthorized access.
The user is responsible for accidents or
hazards to third parties or damage to
their property.
Hand over or lend the power tool only to
persons who are familiar with this model
and its handling – always give them the
instruction manual as well.
The use of noise-emitting machines may
be restricted to certain times by national
or local regulations.
The machine may only be operated by
people who are fit, in good physical
health and in good mental condition.
If you have any condition that might be
aggravated by strenuous work, check
with your doctor before operating a
power tool.
If you have a pacemaker: The ignition
system of this machine produces an
electromagnetic field of very low
intensity. An effect on individual
pacemaker types cannot be excluded
entirely. STIHL recommends that you
consult your doctor and the
manufacturer of your pacemaker in
order to avoid health hazards.
Never work with the machine while
under the influence of alcohol,
medication or drugs capable of impairing
your reaction speed.
Postpone the work if the weather is bad
(snow, ice, wind) – higher risk of
accidents!
The machine is designed only for cutting
as specified. It is not suitable for cutting
wood or wooden objects.
TS 410, TS 420
Asbestos dust is extremely toxic – the
machine must therefore never be used
to cut asbestos!
Do not use the machine for any other
purpose because of the increased risk of
accidents and damage to the machine.
Do not modify the machine – otherwise
safety may be compromised. STIHL
excludes all liability for personal injury
and damage to property caused by
using unauthorized attachments.
Only use abrasive wheels or
accessories which have been approved
by STIHL for this machine or which are
technically equivalent. If you have any
questions in this respect, consult a
servicing dealer. Only use high-quality
abrasive wheels and attachments.
Otherwise there may be a risk of
accidents or damage to the machine.
STIHL recommends the use of genuine
STIHL abrasive wheels and
accessories. These have been
optimized for the product and the user's
requirements.
Do not use a pressure washer to clean
the machine. The strong water jet can
damage parts of the machine.
Do not spray the machine with water.
Never use circular saw
blades, carbide, rescue
or wood cutting attachments or saws of any
kind – these may cause
fatal injuries! Instead of
uniformly removing particles as when cutting with
an abrasive wheel, the
teeth of a circular saw
blade may snag in the
material. This causes the
machine to react in a
highly aggressive manner
with uncontrolled and
extremely dangerous
kickback.
Clothing and equipment
Wear proper protective clothing and
equipment.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear closefitting clothes such as a
boiler suit, not a loose
jacket
When cutting steel, always wear clothing
made of barely flammable material (e.g.,
leather or cotton with flame-retardant
finish) – no man-made fibers – risk of fire
due to flying sparks!
Ensure that there are no flammable
deposits (chips, fuel, oil, etc.) on your
clothing.
Remove any clothes that could be
trapped by moving parts, such as a
scarf, tie or jewelry. Long hair must be
tied up and covered.
3
English
Wear safety boots with
steel toe caps and nonslip soles.
WARNING
To reduce the risk of eye
injuries, wear tight-fitting
safety goggles conforming to standard EN 166.
Make sure that the safety
goggles fit correctly.
Wear a face mask and make sure it fits
correctly. A face mask alone is not
sufficient to protect the eyes.
Wear a hard hat wherever there is any
risk of falling objects.
While working, dust (for example,
crystalline material from the object to be
cut), vapor and smoke may be produced
– danger to health!
Transporting the machine
Always turn off the engine first.
Carry the machine by the handlebar only
– abrasive wheel pointing to the rear –
hot muffler away from the body.
Do not touch hot machine parts, in
particular the muffler surface – risk of
burns!
Different cut-off machines may be
equipped with different filler caps:
In vehicles: Properly secure the machine
to prevent turnover, damage and fuel
spillage.
Bayonet filler cap
Refueling
Gasoline is an extremely
flammable fuel – keep
clear of naked flames and
fire – do not spill any fuel
– no smoking.
Switch off the engine before refueling.
If fumes or smoke are anticipated (e.g.,
when cutting composite materials), wear
respiratory protection.
Never refuel the machine while the
engine is still hot – the fuel may spill over
– risk of fire!
Wear "personal" hearing protection – for
example, ear defenders.
Open the fuel filler cap carefully so that
any excess pressure is relieved
gradually and fuel does not splash out.
STIHL can supply a comprehensive
range of personal protective clothing
and equipment.
4
Look out for leaks! Never
start the engine if fuel has
been spilled or is leaking
- Fatal burns may result!
Never transport the power tool with
cutting wheel fitted – risk of breakage!
Always wear a dust mask if dust is
generated.
Wear sturdy protective
gloves made of a resistant material (e.g.
leather).
Dust may collect on the engine unit,
especially around the carburetor. If dust
gets mixed with fuel – risk of fire!
Remove the dust from the engine unit
regularly.
The machine may only be refueled in a
well ventilated place. If fuel has been
spilled, immediately clean the machine –
do not allow your clothes to be splashed
with fuel. If that happens, change your
clothes at once.
Never use a tool to open or close the
bayonet filler cap. The cap can be
damaged and fuel may escape.
Secure the bayonet filler cap tightly after
refueling.
Filler cap with screw thread
Close the filler cap as
tightly as possible after
refueling.
This helps reduce the risk of engine
vibrations causing an incorrectly
tightened filler cap to loosen or come off
and spill quantities of fuel.

English
Cut-off machine, spindle bearing
Correct spindle bearings ensure the
concentricity and axial running of the
diamond-tipped abrasive wheel – if
necessary, get it checked by an
approved dealer.
Abrasive wheels
Selecting the abrasive wheels
Abrasive wheels must be approved for
hand-held cutting. Do not use other
cutting wheels and attachments – risk of
accident!
Abrasive wheels are suitable for
different materials: Observe the
identification of the abrasive wheels.
STIHL generally recommends wet
cutting.
Observe the outer diameter of the abrasive wheel.
Spindle hole diameter of
the abrasive wheel and
shaft of cut-off machine
must match.
Check the spindle hole for damage. Do
not use cutting wheels with a damaged
spindle hole – risk of accident!
The permissible speed of
the abrasive wheel must
be equal to or greater
than the maximum spindle speed of the cut-off
machine. – Refer to the
chapter "Specifications".
Before fitting a used abrasive wheel,
check that it is not cracked, chipped,
undercut or uneven, and does not
display any signs of core fatigue or
overheating (discoloration); check also
that there are no damaged or missing
segments and that the spindle hole is
not damaged.
Never use cracked, chipped or bent
abrasive wheels.
Substandard and/or unapproved
diamond abrasive wheels can shimmy
during cutting. This shimmying can
cause such diamond abrasive wheels to
be abruptly braked or become stuck in
the cut – Danger of kickback! Kickback
can result in fatal injuries! Diamond
abrasive wheels that shimmy constantly
or even only intermittently must be
replaced immediately.
Position the front pressure plate –
tighten up the clamping screw – rotate
the cutting wheel by hand and take a
sight check for concentricity and axial
running.
Storing abrasive wheels
Store cutting wheels in a dry and frostfree place, on an even surface, at
constant temperature – risk of breakage
and splintering!
Always protect the abrasive wheel
against sudden contact with the ground
or objects.
Before starting
Inspect the cut-off machine to check that
it is in full working order – observe the
respective chapters in the instruction
manual:
–
Check the fuel system for leaks,
especially the visible parts, e.g.,
filler cap, hose connections, manual
fuel pump (only on machines with a
manual fuel pump). In case of
leakage and damage, do not start
the engine – risk of fire! Have the
machine serviced by a servicing
dealer before using it.
–
The abrasive wheel must be
suitable for the material to be cut. It
must be in good condition and fitted
correctly (direction of rotation,
secure).
–
Inspect the cutting wheel guard for
tight seat – if loose, contact your
specialist dealer.
Never straighten diamond abrasive
wheels.
Do not use a cutting wheel which has
fallen to the ground – damaged cutting
wheels may break – risk of accident!
Observe the expiration date where resin
abrasive wheels are concerned.
Fitting abrasive wheels
Inspect the spindle of the cut-off
machine. Do not use a machine if the
spindle is damaged – risk of accident!
TS 410, TS 420
Note the arrows indicating the direction
of rotation on diamond abrasive wheels.

English
–
Slide control / master control / stop
switch must move easily to
STOP or 0
–
Check that the spark plug boot is
secure. A loose boot can lead to
flying sparks which may ignite the
escaping fuel/air mixture – risk of
fire!
–
Never attempt to modify the controls
or safety devices in any way
–
Keep the handles clean, dry, and
free of oil and dirt – important for
good control of the cut-off machine.
–
The machine is operated by a single
person only – do not allow anyone else
within the working area – not even when
starting.
Do not drop-start the engine – start as
described in the Instruction Manual.
After releasing the throttle trigger, the
abrasive wheel keeps on running for a
while – danger of injury due to coasting
effect!
Holding and controlling the machine
The object to be cut has to be firmly
supported. Always guide the machine
towards the workpiece, never the other
way round.
Hand-held cutting
Cut-off machine cart
STIHL cut-off machines can be mounted
on a STIHL cut-off machine cart.
The machine should only be used if it is
in good working order – risk of accident!
On even ground, ensure a firm and
secure footing and hold the power tool
firmly – the cutting wheel must not touch
the ground or any objects and must not
be in the cut.
The abrasive wheel may begin to rotate
as soon as the machine is started.
Guard
002BA549 AM
Move at least 3 meters away from the
place at which the machine was refueled
and never start the machine in an
enclosed space.
When a cut-off machine with an abrasive
wheel rotating is moved in the direction
of the arrow, a force is produced which
causes the machine to tip sideways.
The cut-off machine may only be used
for hand-held cutting or when mounted
on a STIHL cut-off machine cart.
For wet applications, provide
sufficient water
Starting the engine
180BA022 KN
Both the throttle trigger and the
throttle trigger lockout must move
smoothly – the throttle trigger must
automatically return to the idle
position.
The adjustment range of the guard is
determined by a stop pin. Never push
the guard over the stop pin.
Always hold the machine firmly with both
hands: Right hand on the rear handle –
even if you are left-handed. To ensure
reliable control, wrap your thumbs tightly
around the handlebar and handle.

TS 410, TS 420
English
During operation
If there is imminent danger or in an
emergency, immediately stop the
engine – set the slide control / master
lever /stop switch to STOP or 0.
Check for correct idling so that the
abrasive wheel is no longer driven when
the throttle trigger is released and
comes to a complete halt.
Check and/or correct the idle setting
regularly. Have the machine repaired by
a STIHL servicing dealer if the cutting
wheel continues to turn nevertheless.
Keep the working area clear – bear in
mind obstacles, holes and pits.
Take care on ice, water, snow, on slopes
or uneven ground, etc. – risk of slipping!
Do not work while standing on a ladder –
or in unstable places – not above your
shoulder height – not with one hand only
– risk of accident!
Ensure you always have a firm and
secure footing.
Never work alone – always stay in
earshot of other persons who can help in
an emergency.
Keep everyone else away from the
working area – maintain a sufficient
distance from other people to protect
them from noise and flying objects.
Pay increased attention and take
greater care when wearing ear
defenders – the perception of sounds
indicating potential danger (shouts,
audible warnings, etc.) is restricted.
Take a break before it is too late.
TS 410, TS 420
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Work with particular care, do not
endanger others.
Your power tool produces
toxic exhaust fumes as
soon as the engine starts
running. These gases
may be colorless and
odorless and may contain
unburnt hydrocarbons
and benzene. Never use
the machine indoors or in
poorly ventilated areas –
even if your model is
equipped with a catalytic
converter.
operating a machine which is damaged.
In case of doubt, have the unit checked
by your servicing dealer.
Do not work with the throttle trigger in
the starting throttle position – in that
position of the throttle trigger, the engine
speed cannot be controlled.
Never touch a rotating abrasive wheel
with your hand or any other part of your
body.
Check the work area. Avoid danger due
to damage to pipes and electric power
lines.
The machine must not be used in the
vicinity of flammable substances and
combustible gases.
Ensure proper ventilation when working
in trenches, hollows or similar locations
– risk of fatal injury from breathing toxic
fumes!
Do not cut into pipes, metal tanks or
other containers unless you are
absolutely sure that they do not contain
any volatile or flammable substances.
Stop working immediately if you feel
sick, have a headache, distorted vision
(for example, shrinking field of vision),
hearing impairment, dizziness, fading
powers of concentration – such
symptoms may be caused, among other
things, by excessive exhaust
concentrations – risk of accident!
Never leave the machine unattended
with the engine running. Stop the engine
before leaving the machine unattended
(e.g. for breaks).
–
Switch off the engine
No smoking when working with or near
the machine - risk of fire!
–
Wait until the abrasive wheel has
come to a standstill or brake the
abrasive wheel until it comes to a
standstill by carefully touching a
hard surface (e.g., concrete slab)
If the power tool has been exposed to
stress due to improper use (e.g. forceful
impact by striking or dropping), inspect
the machine to make sure it is in full
working order before continuing work, in
every case – see also "Before start-up".
Check the fuel system for leaks and
make sure the safety devices are
working properly. Do not continue
Before putting the cut-off machine down
on the ground:
7
English
In the event of changes in cutting
behavior (e.g., increased vibration,
reduced cutting performance), stop work
and eliminate the causes of the
changes.
Kickback occurs if, for example, the
abrasive wheel
–
gets jammed – especially the upper
quarter, or
–
is abruptly braked through friction
contact with a solid object
002BA555 AM
Frequently inspect the
cutting wheel – replace
the wheel right away if
there are visible cracks,
buckling or other damage
(for example, overheating) – risk of accident due
to breakage!
Reducing the risk of kickback
–
Work cautiously and methodically
–
Hold the cut-off machine firmly with
both hands and maintain a secure
grip
–
Avoid any wedge effect - the
severed part must not brake the
abrasive wheel
–
Always be aware that the object to
be cut may move and other factors
may cause the cut to close and jam
the abrasive wheel.
–
The object to be cut must be
secured and supported so that the
kerf remains open during and after
cutting
–
Objects to be cut must therefore be
fully supported and must be
secured against rolling away,
slipping off or vibrations
Reactive forces
002BA552 AM
The most frequently occurring reactive
forces are kickback and pull-in.
Danger of kickback –
Kickback can result in
fatal injuries.
Do not use the upper quarter of the
abrasive wheel for cutting. Use
extreme caution when guiding the
abrasive wheel into a cut, do not
twist or push into the cut
002BA551 AM
–
Kickback occurs when the cut-off
machine is suddenly thrown up and back
in an uncontrolled arc towards the
operator.
8
TS 410, TS 420
English
–
An exposed pipe must be provided
with a stable support that will bear
its weight, using wedges if
necessary – always bear in mind a
proper support and the nature of the
ground – material may crumble
away
–
Always work with water and wet
cutting when using diamond
abrasive wheels
–
Depending on the version, resin
abrasive wheels are only suitable
for dry cutting or only for wet cutting.
Always use wet cutting with
composite resin abrasive wheels
that are suitable only for wet cutting
Pulling away
The abrasive wheel must
be guided straight in the
cut, without wedging.
Never exert lateral pressure on the abrasive
wheel.
Do not use for lateral
grinding or roughing.
Do not stand in line with the abrasive
wheel. Ensure sufficient freedom of
movement, especially in construction
trenches there must be sufficient space
for the user and for the part being cut to
fall.
002BA553 AM
Do not lean too far forwards and never
bend over the abrasive wheel, especially
when the guard has been pulled back.
The cut-off machine pulls forwards,
away from the user, when the abrasive
wheel touches the object to be cut from
above.
TS 410, TS 420
Always decide the cutting direction
before positioning the cut-off machine.
Do not change the cutting direction.
Never use the machine to push or hit
into the cutting gap – do not let the
machine fall into the gap – risk of
breakage!
Diamond abrasive wheels: If cutting
performance begins to deteriorate,
check the sharpness of the diamond
cutting wheel, resharpen as needed. To
do this, briefly cut through abrasive
material, e.g., sandstone, aerated
concrete or asphalt.
At the end of the cut, the cut-off machine
is no longer supported in the cut by the
abrasive wheel. The user has to absorb
the weight force – risk of loss of control!
002BA554 AM
002BA556 AM
Working – cutting
Do not work above shoulder height.
The cut-off machine may only be used
for cutting. It must not be used as a lever
or shovel.
Do not press down on the cut-off
machine.
When cutting steel: glowing metal particles may
cause fires!
Keep water and sludge away from live
electrical cables – risk of electric shock!
Pull the cutting wheel into the workpiece
– do not push it into the material. Do not
use the cut-off machine to correct
severing cuts. Do not re-cut – remove
any webs or breaking edges manually
(for example, with a hammer).
When using diamond-coated cutting
wheels, make a wet cut – for example,
use the STIHL water connector.
Depending on the version, resin
abrasive wheels are only suitable for dry
cutting or only for wet cutting.
9
English
When using cutting wheels made from
synthetic resin which are suitable for wet
cuts only, make wet cuts only – for
example, use the STIHL water
connector.
When using abrasive wheels made from
synthetic resin, which are suitable for dry
cuts only, make dry cuts only. If
composite resin abrasive wheels of this
type become wet, their cutting
performance is reduced and they
become dull. If composite resin abrasive
wheels of this type become wet while
working (e.g., due to puddles or water in
pipes), do not increase the cutting
pressure, but continue working with the
same pressure – risk of breakage! Use
up such composite resin abrasive
wheels immediately.
Cut-off machine cart
Clear a path for the cut-off machine cart.
If the cart is pushed over objects, the
abrasive wheel may become wedged in
the cut and shatter!
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
–
Hand protection (wearing warm
gloves)
–
Work breaks
10
The period of usage is shortened by:
–
Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
–
Low outside temperatures.
–
The force with which the handles
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and repairs
The machine must be serviced regularly.
Do not attempt any maintenance or
repair work not described in the
Instruction Manual. All other work should
be carried out by a servicing dealer.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers. STIHL
dealers receive regular training and are
supplied with technical information.
Use only high-quality replacement parts,
in order to avoid the risk of accidents or
damage to the machine. Contact a
dealer if in doubt.
injury if the engine starts up
inadvertently! – Exception: adjustment
of carburetor and idle speed.
To reduce the risk of fire due to ignition
outside the cylinder, move the slide
control / stop switch to STOP or 0 before
turning the engine over on the starter
with the spark plug boot removed or the
spark plug unscrewed.
Do not service or store the machine near
a naked flame – risk of fire due to the
fuel.
Check fuel cap regularly for tightness.
Use only spark plugs that are in perfect
condition and have been approved by
STIHL – see Specifications.
Inspect ignition lead (insulation in good
condition, secure connection).
Check that the muffler is in perfect
working condition.
Do not use the machine if the muffler is
damaged or missing - risk of fire! –
Hearing damage!
Never touch a hot muffler – risk of burns!
Check the rubber buffers underneath
the machine - the housing must not rub
against the ground - risk of damage!
The condition of the antivibration
elements influences vibration behavior –
inspect antivibration elements
periodically.
STIHL recommends the use of genuine
STIHL spare parts. Such parts have
been optimized for the machine and the
user's requirements.
Before starting any maintenance or
repair work and before cleaning the
machine, always stop the engine and
disconnect the spark plug boot – risk of

During dry cutting, wear a suitable dust
mask.
TS 410, TS 420
With openings, recesses, etc., the
sequence of the cuts is important.
Always make the last cut so that the
abrasive wheel does not become
jammed and so that the operator is not
endangered by the severed or
separated part.
If necessary, leave small ridges that hold
the part that is to be separated in
position. Break these ridges later.
Extend service life and increase cutting
speed
Always ensure a supply of water to the
abrasive wheel.
Severed parts
To bind dust, the abrasive wheel must
be supplied with at least 1 liter of water
per minute. To avoid a reduction in
cutting performance, the abrasive wheel
must be supplied with not more than
4 liters of water per minute.
After using the abrasive wheel, the
wheel should be allowed to continue
spinning at operating speed for
approx. 3 to 6 seconds without water in
order to spin off the water remaining on
it.

Diamond Abrasive Wheels
The product code is a combination of
letters and numbers, consisting of up to
four characters:
–
the letters denote the main field of
application of the abrasive wheel
–
the numbers denote the
performance class of the STIHL
diamond abrasive wheel
An excessively high radial run-out
deviation (A) overloads individual
diamond segments, which overheat in
the process. This can lead to stress
cracks in the parent wheel or to
annealing of individual segments.
Deviations in axial run-out (B) result in
higher thermal loading and wider cuts.
Axial and radial run-out
A faultless spindle bearing of the cut-off
machine is necessary for a long service
life and efficient functioning of the
diamond abrasive wheel.
Using the abrasive wheel on a cut-off
machine with a faulty spindle bearing
can lead to deviations in radial and axial
run-out.
Do not cut any other materials – Risk of
accident!
Never use diamond abrasive wheels
with side plating as they jam in the cut
and can result in extreme kickback –
Risk of accident!

Undercut
Do not cut into the base course
(frequently chipped stones and gravel)
when cutting roadway pavement –
cutting in chipped stones and gravel is
revealed by light-colored dust –
excessive undercut may occur as a
result – Danger of shattering!
Built-up edges increase vibration,
reduce cutting performance, and cause
formation of sparks.
Electronic Water Control
At the first signs of built-up edges,
immediately "sharpen" the diamond
abrasive wheel – to do this, briefly cut
through abrasive material such as e. g.
sandstone, aerated concrete or asphalt.
STIHL cut-off machines may be
equipped with an electronic water
control system.
Addition of water prevents the formation
of built-up edges.
The electronic water control makes it
possible to feed the optimum amount of
water to the abrasive wheel. No water is
fed to the abrasive wheel during idling.
Before starting work
N
Familiarize yourself with the
sequence of motions while the
engine is switched off
N
All of the control panel buttons can
be operated with the thumb of the
right hand – the right hand always
remains on the rear handle while
doing so
N
The left hand always remains on the
handlebar
Built-up edges take the form of a light
gray deposit on the tops of the diamond
segments. This deposit on the segments
clogs the diamonds and blunts the
segments.
Built-up edges can form:
–
when cutting extremely hard
materials, e. g., granite
–
with incorrect handling, e. g.,
excessive feed effort
TS 410, TS 420
If work continues with dull segments,
these may soften due to the high heat
generated – the parent wheel is
annealed and its strength is
compromised – this can lead to stresses
that are clearly recognizable by
gyrations of the abrasive wheel. Do not
continue to use the abrasive wheel –
Risk of accident!

STIHL recommends the use of STIHL
MotoMix. This ready-to-use fuel mix
contains no benzol or lead, has a high
octane rating and ensures that you
always use the right mix ratio.
STIHL MotoMix uses STIHL HP Ultra
two-stroke engine oil for an extra long
engine life.
MotoMix is not available in all markets.
Mixing Fuel
NOTICE
Unsuitable fuels or lubricants or mix
ratios other than those specified may
result in serious damage to the engine.
Poor quality gasoline or engine oil may
damage the engine, sealing rings, hoses
and the fuel tank.
Gasoline
Use only high-quality brand-name
gasoline with a minimum octane rating
of 90 – leaded or unleaded.
TS 410, TS 420
English
If your machine is equipped with a
catalytic converter, you must use
unleaded gasoline.
NOTICE
A few tankfuls of leaded gasoline will
greatly reduce the efficiency of the
catalytic converter.
Gasoline with an ethanol content of
more than 10% can cause running
problems in engines with a manually
adjustable carburetor and should not be
used in such engines.
Engines equipped with M-Tronic deliver
full power when run on gasoline with an
ethanol content of up to 25% (E25).
Engine oil
Use only high-quality two-stroke engine
oil – preferably STIHL HP, HP Super or
HP Ultra, which are specially formulated
for use in STIHL engines. HP Ultra
guarantees high performance and a
long engine life.
These engine oils are not available in all
markets.
Use only STIHL 50:1 two-stroke engine
oil for the fuel mix in models with a
catalytic converter.

add gasoline and mix thoroughly.
Storing Fuel
Store fuel only in approved safety-type
fuel canisters in a dry, cool and safe
location protected from light and the sun.
Fuel mix ages – only mix sufficient fuel
for a few weeks work. Do not store fuel
mix for longer than 30 days. Exposure to
light, the sun, low or high temperatures
can quickly make the fuel mix unusable.
STIHL MotoMix may be stored for up to
2 years without any problems.

In the long-life air filter system with the
cyclone pre-separation system, dirty air
is drawn in and deliberately rotated. The
larger and heavier particles carried in
the air are thus expelled and extracted.
Only pre-cleaned air enters the air filter
system and the result is extremely long
filter life.
