In the STIHL KombiSystem a number of
different KombiEngines and KombiTools
can be combined to produce a power
tool. In this instruction manual the
functional unit formed by the
KombiEngine and KombiTools 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.

operate your power tool or attend a
special course in its operation.
Minors should never be allowed to use a
power tool.
Keep bystanders, especially children,
and animals 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 machine only to
persons who are familiar with this model
and its operation – do not lend of rent
your machine without the KombiEngine
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
aggravated by strenuous work, check
with your doctor before operating a
power tool.
Persons with pacemakers only: The
ignition system of your power tool
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce health risks, STIHL recommends
that persons with pacemakers consult
their physician and the pacemaker
manufacturer before operating this tool.
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 KombiTool you are using.
Do not use your power tool for any other
purpose since this may result in
accidents.
Do not operate the KombiEngine without
a properly mounted KombiTool since
this may result in damage to the
machine.
Only use KombiTools and accessories
that are explicity 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 parts and accessories in order to
avoid the risk of accidents and damage
to the machine.
STIHL recommends the use of original
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
Never attempt to modify your power tool
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.
Clothing and Equipment
Wear proper protective clothing and
equipment.
See also notes on "Clothing and
Equipment" in the instruction manual of
the KombiTool you are using.
Safety Precautions and
Working Techniques
Special safety precau-
tions must be observed
when working with a
power tool.
Always read and and
make sure you under-
stand both instruction
manuals (KombiEngine
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.

Transporting the Power Tool
Always turn off the engine.
Transporting in a 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.
Fueling
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 immediately – if fuel gets on
your clothing, change immediately.
Your power tool comes standard with
either a screw-type or bayonet-type fuel
cap. After fueling,
This reduces the risk of unit vibrations
causing the fuel cap to loosen or come
off and spill quantities of fuel.
To reduce the risk of serious or fatal
burn injuries, check for fuel leakage. If
fuel leakage is found, do not start or run
the engine until leak is fixed.
Before starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the instruction
manuals.
–Use only an approved combination
of cutting attachment, deflector,
handle and harness. All parts must
be assembled properly and
securely.
–Slide control / stop switch must
move easily to STOP or 0
–Smooth action of throttle trigger
lockout and throttle trigger – the
throttle trigger must return
automatically to the idle position.
–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 the safety devices in any way.
–Keep the handles dry and clean –
free from oil and dirt – for safe
control of the power tool.
–Adjust harness and handle to suit
your height and reach.
To reduce the risk of personal injury,
do not operate your power tool if it is
damaged or not properly assembled.
If you use a shoulder strap or full
harness: Practice 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.
Starting the Engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The working tool 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 working tool.
Gasoline is an
extremely flammable
fuel. Keep clear of naked
flames. Do not spill any
fuel – do not smoke.
tighten down the screw-
type fuel cap as securely
as possible.
Insert the fuel cap with
hinged grip (bayonet-type
cap) correctly in the
opening, turn it clockwise
as far as stop and fold the
grip down.

Do not drop start the power tool – start
the engine as described in the
instruction manual. Note that the
working tool continues to run for a short
period after you let go of the throttle
trigger – flywheel effect.
Check idle speed setting: The working
tool 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 combustible materials (e.g.
wood chips, bark, dry grass, fuel).
See also notes on "Starting / Stopping
the Engine" in the instruction manual of
the KombiTool you are using.
Holding and Controlling the Power
Tool
Always hold the unit firmly with both
hands on the handles.
Make sure you always have good
balance and secure footing.
Left hand on loop handle, right hand on
control handle, even if you are left-
handed.
During Operation
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch to STOP or 0.
The correct engine idle speed is
important to ensure that the working tool
stops moving when you let go of the
throttle trigger. If the working tool
continues to move when the engine is
idling, have your dealer check the
machine and make proper adjustments
or repairs. Check and correct the idle
speed setting at regular intervals. STIHL
recommends you have this work done
by a 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 for those
applications described in the KombiTool
instruction manual.
To reduce the risk of serious or fatal
injury from breathing toxic fumes,
ensure proper ventilation when working
in trenches, hollows or other confined
locations.
To reduce the risk of accidents, stop
work immediately in the event of
nausea, headache, visual disturbances
(e.g. reduced field of vision), problems
with hearing, dizziness, deterioration in
ability to concentrate. Apart from other
possibilities, these symptoms may be
caused by an excessively 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 for cutting.
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 conditions.
002BA273 KN
Your power tool produces
toxic exhaust fumes as
soon as the engine is
running. These fumes
may be colorless and
odorless and contain
unburned hydrocarbons
and benzol. Never run
the engine indoors or in
poorly ventilated loca-
tions, even if your model
is equipped with a cata-
lytic converter.

KM 110 R, KM 130 R

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 particular for leaks and make sure the
safety devices are working properly. Do
not continue operating your power tool if
it is damaged. In case of doubt, have the
machine checked by your servicing
dealer.
Do not operate your power tool with the
starting throttle lock engaged – engine
speed cannot be controlled 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 working tool.
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 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
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized 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, always shut
off the engine before carrying out any
maintenance or repairs or cleaning the
machine. – Exception: Carburetor and
idle speed adjustments.
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed unless the slide control /
stop switch is on STOP or 0since 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 intervals.
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 condition, 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. –
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.
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

A properly adjusted throttle cable is the
precondition for correct operation in the
full throttle, starting throttle and idle
positions.
NAdjust the throttle cable only when
the unit is completely and properly
assembled.
NUse a suitable tool to push the slide
to the end of the slot (see
illustration).
NPress down the throttle trigger
lockout (1) and squeeze the throttle
trigger (2) (full throttle) – this sets
the throttle cable correctly.
The STIHL 4-MIX engine features
mixture lubrication and must be run on a
fuel mixture of gasoline and engine oil.
It operates otherwise on the 4-stroke
principle.
This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your engine requires a mixture of high-
quality premium gasoline and high-
quality two-stroke air-cooled engine oil.
Use premium branded unleaded
gasoline with a minimum octane rating
of 89 RON.
Note: Models equipped with a catalytic
converter require unleaded gasoline. A
few tankfuls of leaded gasoline can
reduce the efficiency of the catalytic
converter by more than 50%.
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 the 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
high-quality fuels!
Fuels with different percentages of
ethanol are being offered. Ethanol can
affect the running behaviour of the
engine and increase the risk of lean
seizure.

Gasoline with an ethanol content of
more than 10% can cause running
problems and major damage in engines
with a manually adjustable carburetor
and should not be used in such engines.
Engines equipped with M-Tronic can be
run on gasoline with an ethanol content
of up to 25% (E25).
Use only STIHL two-stroke engine oil or
equivalent high-quality two-stroke air-
cooled engine oils for mixing.
We recommend STIHL 50:1 two-stroke
engine oil since it is specially formulated
for use in STIHL engines.
Do not use BIA or TCW (two-stroke
water cooled) mix oils!
Use only STIHL 50:1 heavy-duty
engine oil or an equivalent quality two-
stroke engine oil for the fuel mix in
models equipped with a catalytic
converter.
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapour.
The canister should be kept tightly
closed in order to avoid any moisture
getting into the mixture.
The fuel tank and the canister in which
fuel mix is stored should be cleaned
from time to time.
Fuel mix ratio
Only mix sufficient fuel for a few days
work, not to exceed 3 months of storage.
Store in approved safety fuel-canisters
only. When mixing, pour oil into the
canister first, and then add gasoline.
Dispose of empty mixing-oil canisters
only at authorized disposal locations.
Preparations
NBefore fueling, clean the filler cap
and the area around it so that dirt
cannot fall into the tank.
NAlways position the machine so that
the filler cap is facing upwards.
A number of different filler caps are
installed as standard at the factory.

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.
During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat can be dissipated by the flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Storing for a short period: Wait for the
engine to cool down. Empty the fuel tank
and keep the machine in a dry place,
well away from sources of ignition, until
you need it again. For longer out-of-
service perionds – see "Storing the
Machine".

The carburetor comes from the factory
with a standard setting.
The carburetor has been adjusted for
optimum performance and fuel
efficiency in all operating states.
The high speed adjusting screw and low
speed adjusting screw on this carburetor
can only be set within narrow limits.
Standard position
NSwitch off engine
NMount KombiTool with attached
working or cutting tool
NCheck air filter - clean or replace it if
necessary
NCheck throttle cable adjustment,
adjust if necessary – see "Adjusting
the throttle cable"
NCheck spark arresting screen -
clean or replace it if necessary
NCarefully turn both adjusting screws
counterclockwise until they are
seated firmly:
–High speed screw (H) is 3/4 of a
turn open
–Low speed screw (L) is 3/4 of a turn
open.
NStart the machine and let the engine
warm up
NUsing the idle speed screw (LA), set
the idle speed so that the working
tool does not move
Fine adjustment
A marginal adjustment of the setting of
the high speed screw (H) may be
necessary if the engine does not run
satisfactorily in mountain country, at sea
level or after changing working tools.
Approx. value
Turn the high speed screw (H) approx.
1/4 turn per 1000 m (3300 ft) difference
in elevation
NCarry out standard adjustment for
idle speed screw (L)
NLet the engine warm up for
approx. 3 min
NOpen the throttle fully
In the mountains
NTurn the high speed screw (H)
clockwise (leaner) – until there is no
longer a noticeable increase in
speed – max. as far as possible
At sea level
NTurn the high speed screw (H)
counterclockwise (richer) – until
there is no longer a noticeable
increase in speed – max. as far as
possible
It is possible that the maximum speed is
already obtained at the standard setting.
Setting the idle speed
Whenever the low speed screw (L) has
been adjusted, it is usually also
necessary to adjust the idle speed
screw (LA).
NLet the engine warm up for
approx. 3 min
Engine stops when idling
NSlowly turn idle speed screw (LA)
clockwise until the engine runs
smoothly – the working tool must
not move

NTurn the idle speed screw (LA)
counterclockwise until the working
tool stops moving – then turn
another 1/2 to 3/4 turn in the same
direction
Erratic idling behavior, engine stalls
despite correction of LA-setting, poor
acceleration
The idle setting is too lean:
NTurn the low speed screw (L)
counterclockwise until the engine
runs and accelerates smoothly – but
no further than the stop
Erratic idling behavior
The idle setting is too rich:
NTurn the low speed screw (L)
clockwise until the engine runs and
accelerates smoothly – but no
further than the stop
In some countries the muffler is
equipped with a spark arresting screen.
NIf the engine is down on power,
check the spark arresting screen in
the muffler.
NWait for the muffler to cool down.
NMove the slide control to STOP-0.
NTake out the screw (1).
NTake out the screws (2) and remove
the shroud (3).
NTake out the screw (4).
NLift the spark arresting screen (5)
and pull it out.
NClean the spark arresting screen. If
the screen is damaged or heavily
carbonized, fit a new one.
NRefit the spark arresting screen.
NInsert the screw and tighten it down
firmly.

NIf the engine is down on power,
difficult to start or runs poorly at idle
speed, first check the spark plug.
NFit a new spark plug after about 100
operating hours – or sooner if the
electrodes are badly eroded. Install
only suppressed spark plugs of the
type approved by STIHL – see
"Specifications".
Removing the spark plug
NMove the slide control to STOP-0.
NPull off the spark plug boot (1).
NUnscrew the spark plug.
Checking the spark plug
NClean dirty spark plug.
NCheck electrode gap (A) and
readjust if necessary – see
"Specifications".
NRectify the problems which have
caused fouling of the spark plug.
Possible causes are:
–Too much oil in fuel mix.
–Dirty air filter.
–Unfavorable running conditions.
Installing the spark plug
NScrew the spark plug (3) into the
cylinder and fit the boot (2) (press it
