KombiSystem Guide to Using this Manual

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 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.

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 (KombiEngine
and KombiTool) before
using your power tool for
the first time and keep
them in a safe place for
future reference. Non­observance 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 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 power tool only to
persons who are familiar with this model
and its operation – do not lend your
power tool 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. STIHL
recommends 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 KombiTool you are using.

Do not use your po we r tool for any other
purpose because of the increased risk of
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 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 accidents 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.

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 and con­fine long hair (e.g. with a
hair net, cap, hard hat,
etc.).

See also notes on "Clothing and
Equipment" in the instruction manual of
the KombiTool you are using.

Transporting the Power Tool

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.

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 well­ventilated areas. If you spill fuel, wipe
the machine immediately – 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 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.

– Check the fuel system for leaks,

paying special 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 position 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, 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.

Start the engine.

Start the engine at least 3 meters from
the fueling spot, outdoors only.

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 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 power tool firmly with
both hands on the handles.

Make sure you always have good
balance and secure footing.

Models with bike handle

Right handle on control handle, left hand
on left handle.

Models with loop handle

Left hand on loop handle, right hand on
control handle, even if you are left­handed.

During Operation

In the event of imminent danger or in an
emergency, switch off the engine
immediately – operate 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
recommends 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

0000-GXX-0492-A0

may be colorless 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 cata­lytic converter.

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

KM 111 R, KM 131, KM 131 R

English

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 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 conditions.

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, consult
your servicing dealer.

Do not operate your power tool in the
starting throttle position – 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 attachment.

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 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
adjustments.

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 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.
