1 KombiSystem
In the STIHL KombiSystem a number of different
KombiEngines and KombiTools can be com‐
bined to produce a power tool. In this instruction
manual the functional unit formed by the Kom‐
biEngine and KombiTool is referred to as the
power tool.
Therefore, the separate instruction manuals for
the KombiEngine and KombiTool should be used
together for the power tool.
Always read and and make sure you understand
both instruction manuals before using your
power tool for the first time and keep them in a
safe place for future reference.

3 Safety Precautions and
Working Techniques
Special safety precautions must be
observed when working with a power
tool.
Always read and and make sure you
understand both instruction manuals
(KombiMotor and KombiTool) before
using your power tool for the first time
and keep them in a safe place for
future reference. Non-observance of
the safety precautions may result in
serious or even fatal injury.
Observe all applicable local safety regulations,
standards and ordinances.
If you have not used this type of power tool
before: Have your dealer or other experienced
user show you how it is operated or attend a
special course in its operation.
Minors should never be allowed to use a power
tool.
Keep bystanders, especially children, and ani‐
mals away from the work area.
When the power tool is not in use, shut it off so
that it does not endanger others. Secure it
against unauthorized use.
The user is responsible for avoiding injury to third
parties or damage to their property.
Lend or rent your power tool only to persons who
are familiar with this model and its operation – do
not lend your power tool without the KombiMotor
and KombiTool instruction manuals.
The use of noise emitting power tools may be
restricted to certain times by national or local
regulations.
To operate the power tool you must be rested, in
good physical condition and mental health.
If you have any condition that might be aggrava‐
ted by strenuous work, check with your doctor
before operating a power tool.
Persons with pacemakers only: The ignition sys‐
tem of your power tool produces an electromag‐
netic field of a very low intensity. This field may
interfere with some pacemakers. STIHL recom‐
mends that persons with pacemakers consult
their physician and the pacemaker manufacturer
to reduce any health risk.
Do not operate the power tool if you are under
the influence of any substance (drugs, alcohol)
which might impair vision, dexterity or judgment.
Use your power tool only for the applications
described in the instruction manual of the Kombi‐
Tool you are using.
Do not use your power tool for any other purpose
because of the increased risk of accidents.
Do not operate the KombiEngine without a prop‐
erly mounted KombiTool since this may result in
damage to the machine.
Only use KombiTools and accessories that are
explicitly approved for this power tool by STIHL
or are technically identical. It is important that
you read the chapter on "Approved KombiTools".
If you have any questions in this respect, consult
a servicing dealer. Use only high quality tools
and accessories in order to avoid the risk of acci‐
dents and damage to the machine.
STIHL recommends the use of genuine STIHL
tools and accessories. They are specifically
designed to match the product and meet your
performance requirements.
Never attempt to modify your machine in any
way since this may increase the risk of personal
injury. STIHL excludes all liability for personal
injury and damage to property caused while
using unauthorized attachments.
Do not use a pressure washer to clean your
power tool. The solid jet of water may damage
parts of the power tool.
3.1 Clothing and Equipment
Wear proper protective clothing and equipment.
Avoid clothing that could get caught
on branches or brush or moving parts
of the machine. Do not wear a scarf,
necktie or jewelry. Tie up long hair so
that it is above shoulder level.
See also notes on "Clothing and Equipment" in
the instruction manual of the KombiTool you are
using.

3.2 Transporting the Power Tool
002BA079 KN
Always shut off the engine.
Transporting by vehicle: Properly secure your
power tool to prevent turnover, fuel spillage and
damage.
See also notes on "Transporting the Machine" in
the instruction manual of the KombiTool you are
using.
3.3 Fueling
Gasoline is an extremely flammable
fuel. Keep clear of naked flames. Do
not spill any fuel – do not smoke.
Always shut off the engine before refueling.
Do not fuel a hot engine – fuel may spill and
cause a fire.
Open the fuel cap carefully to allow any pressure
build-up in the tank to release slowly and avoid
fuel spillage.
Fuel your power tool only in well-ventilated
areas. If you spill fuel, wipe the machine immedi‐
ately – if fuel gets on your clothing, change
immediately.
After fueling, tighten down the fuel
tank cap as securely as possible.
This reduces the risk of unit vibrations causing
the fuel cap to loosen or come off and spill quan‐
tities of fuel.
To reduce the risk of serious or fatal burn inju‐
ries, check for fuel leakage. If fuel leak is found,
do not start the engine.
3.4 Before Starting
Check that your power tool is properly assem‐
bled and in good condition – refer to appropriate
chapters in the instruction manuals.
–Check the fuel system for leaks, paying spe‐
cial attention to visible parts such as the tank
cap, hose connections and the manual fuel
pump (on machines so equipped). If there are
any leaks or damage, do not start the engine –
risk of fire. Have your machine repaired by a
servicing dealer before using it again.
–Use only an approved combination of cutting
attachment, deflector, handle and harness. All
parts must be assembled properly and
securely.
–The stop switch must move freely.
–Check smooth action of choke knob, throttle
trigger lockout and throttle trigger – the throttle
trigger must return automatically to the idle
position. The choke knob must spring back
from the g and < positions to the run posi‐
tion F when the throttle trigger lockout and
throttle trigger are squeezed.
–Check that the spark plug boot is secure – a
loose boot may cause arcing that could ignite
combustible fumes and cause a fire.
–Never attempt to modify the controls or safety
devices in any way.
–Keep the handles dry and clean – free from oil
and dirt – for safe control of the power tool.
–Adjust the harness and handle(s) to suit your
height and reach.
To reduce the risk of accidents, operate your
power tool only if it is in a safe condition.
If you use a shoulder strap or full harness: Prac‐
tice removing and putting down the machine as
you would in an emergency. To avoid damage,
do not throw the machine to the ground when
practicing.
See also notes on "Before Starting" in the
instruction manual of the KombiTool you are
using.
3.5 Starting the Engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
English 3 Safety Precautions and Working Techniques
4 0458-436-0121-B
Place the power tool on firm ground in an open
area. Make sure you have good balance and
secure footing. Hold the power tool securely. The
attachment must be clear of the ground and all
other obstructions because it may begin to run
when the engine starts.
To reduce the risk of injury, avoid contact with
the attachment.
Do not drop start the power tool – start the
engine as described in the instruction manual.
Note that the attachment continues to run for a
short period after you let go of the throttle trigger
– flywheel effect.
Check idle speed setting: The attachment must
be stationary when the engine is idling with the
throttle trigger released.
To reduce the risk of fire, keep hot exhaust
gases and hot muffler away from easily combus‐
tible materials (e.g. wood chips, bark, dry grass,
fuel).
See also notes on "Starting / Stopping the
Engine" in the instruction manual of the Kombi‐
Tool you are using.
3.6 Holding and Controlling the
Power Tool
Always hold the power tool firmly with both
hands on the handles.
Make sure you always have good balance and
secure footing.
3.6.1 Models with bike handle
002BA257 KN
Right handle on control handle, left hand on left
handle.
3.6.2 Models with loop handle
0000-GXX-0492-A0
Left hand on loop handle, right hand on control
handle, even if you are left-handed.
3.7 During Operation
In the event of imminent danger or in an emer‐
gency, switch off the engine immediately – oper‐
ate the stop switch.
The correct engine idle speed is important to
ensure that the attachment stops moving when
you let go of the throttle trigger. If the attachment
continues to run when the engine is idling, have
your dealer check your machine and make
proper adjustments or repairs. Check and correct
the idle speed setting regularly. STIHL recom‐
mends an authorized STIHL servicing dealer.
Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.
To reduce the risk of accidents, take a break in
good time to avoid tiredness or exhaustion.
Work calmly and carefully – in daylight conditions
and only when visibility is good. Stay alert so as
not to endanger others.
Use your power tool only in the areas specified in
the KombiTool instruction manual.
Your power tool produces toxic
exhaust fumes as soon as the engine
is running. These fumes may be col‐
orless and odorless and contain
unburned hydrocarbons and benzol.
Never run the engine indoors or in
poorly ventilated locations, even if
your model is equipped with a cata‐
lytic converter.
To reduce the risk of serious or fatal injury from
breathing toxic fumes, ensure proper ventilation
when working in trenches, hollows or other con‐
fined locations.
To reduce the risk of accidents, stop work imme‐
diately in the event of nausea, headache, visual
disturbances (e.g. reduced field of vision), prob‐
3 Safety Precautions and Working Techniques English
0458-436-0121-B 5
lems with hearing, dizziness, deterioration in abil‐
ity to concentrate. Apart from other possibilities,
these symptoms may be caused by an exces‐
sively high concentration of exhaust gases in the
work area.
Operate your power tool so that it produces a
minimum of noise and emissions – do not run the
engine unnecessarily, accelerate the engine only
when working.
To reduce the risk of fire, do not smoke while
operating or standing near your power tool. Note
that combustible fuel vapor may escape from the
fuel system.
The dusts, vapor and smoke produced during
operation may be dangerous to health. Wear a
suitable respirator in very dusty or smoky condi‐
tions.
If your power 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 – see also
"Before Starting". Check the fuel system in par‐
ticular for leaks and make sure the safety devi‐
ces are working properly. Do not continue oper‐
ating your power tool if it is damaged. In case of
doubt, consult your servicing dealer.
Do not operate your power tool in the starting
throttle position – engine speed cannot be con‐
trolled in this position.
Before leaving the power tool unattended: Shut
off the engine.
To reduce the risk of injury, always shut off the
engine before changing the KombiTool or attach‐
ment.
3.8 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
The period of usage is shortened by:
–Any personal tendency to suffer from poor cir‐
culation (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.
3.9 Maintenance and Repairs
Service the machine regularly. Do not attempt
any maintenance or repair work not described in
the instruction manual. Have all other work per‐
formed by a servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer. STIHL dealers are
regularly given the opportunity to attend training
courses and are supplied with the necessary
technical information.
Only use high-quality replacement parts in order
to avoid the risk of accidents and damage to the
machine. If you have any questions in this
respect, consult a servicing dealer.
STIHL recommends the use of original STIHL
replacement parts. They are specifically
designed to match your model and meet your
performance requirements.
To reduce the risk of injury from unintentional
engine startup, always shut off the engine and
disconnect the spark plug boot before performing
any repairs, maintenance or cleaning work. –
Exception: Carburetor and idle speed adjust‐
ments.
Do not turn the engine over on the starter with
the spark plug boot or spark plug removed since
there is otherwise a risk of fire from uncontained
sparking.
To reduce the risk of fire, do not service or store
your machine near open flames.
Check the fuel filler cap for leaks at regular inter‐
vals.
Use only a spark plug of the type approved by
STIHL and make sure it is in good condition –
see "Specifications".
Inspect the ignition lead (insulation in good con‐
dition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to hearing,
do not operate your machine if the muffler is
damaged or missing. –
English 3 Safety Precautions and Working Techniques
6 0458-436-0121-B
Do not touch a hot muffler since burn injury will
result.
Vibration behavior is influenced by the condition
of the AV elements – check the AV elements at
regular intervals.
