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.

products periodically.
Therefore, some changes, modifications and
improvements may not be covered in this man‐
ual.
3 Safety Precautions and
Working Techniques
Special safety precautions must be
observed when working with this
power edger because it has a sharp
cutting blade that rotates at very high
speed.
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.
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.
Use the power edger only for cutting the edges
of paths, flower beds and lawns.
Do not use your power tool for any other purpose
because of the increased risk of accidents.
Only use blades and accessories that are explic‐
itly approved for this power tool by STIHL or are
technically identical. 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.
The deflector on this power edger cannot protect
the operator from all objects thrown by the cut‐
ting blade (stones, glass, wire, etc.). Such
objects may ricochet and then hit the operator.
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.
Clothing must be sturdy but allow
complete freedom of movement.
Wear snug-fitting clothing, an overall
and jacket combination, do not wear
a work coat.
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.
Wear steel-toed safety boots with
non-slip soles.
WARNING
To reduce the risk of eye injuries,
wear close-fitting safety glasses in
accordance with European Standard
EN 166. Make sure the safety
glasses are a comfortable and snug
fit.
Wear hearing protection, e.g. earplugs or ear
muffs.
Wear a face shield and make sure it is a good fit.
A face shield alone does not provide adequate
eye protection.
Wear heavy-duty work gloves made
of durable material (e.g. leather).
STIHL offers a comprehensive range of personal
protective clothing and equipment.
3.2 Transporting the Power Tool
002BA079 KN
Always shut off the engine.
Carry the power tool properly balanced by the
drive tube – cutting blade in front of you.
Do not touch hot parts of the machine since burn
injury will result.
Transporting by vehicle: Properly secure your
power tool to prevent turnover, fuel spillage and
damage.
3.3 Before Starting
Check that your power tool is properly assem‐
bled and in good condition – refer to appropriate
chapters in the KombiMotor and KombiTool
instruction manuals.
–Blade correctly and securely mounted and in
good condition (clean, move freely, not war‐
ped).
–Inspect the deflectors for damage and wear.
Do not operate the machine with a damaged
deflector – replace damaged parts.
–Never attempt to modify the controls or safety
devices – work only with a properly mounted
deflector.
–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.
3 Safety Precautions and Working Techniques English
0458-471-0121-C 3
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.
3.4 Holding and Controlling the
Power Tool
Make sure you always have good balance and
secure footing.
Always hold the power tool firmly with both
hands on the handles.
3.4.1 Models with loop handle

handle.
3.5 During Operation
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the slide control / stop switch / button to
0 or STOP.
15m (50ft)
The cutting attachment may catch and fling
objects a great distance and cause injury - there‐
fore, do not allow any other persons within a
radius of 15 meters of your own position. To
reduce the risk of damage to property, also main‐
tain this distance from other objects (vehicles,
windows). Even maintaining a distance of 15
meters or more cannot exclude the potential dan‐
ger.
To reduce the risk of injury, avoid
contact with the blade.
The correct engine idle speed is important to
ensure that the blade stops moving when you let
go of the throttle trigger. Check and correct the
idle speed setting regularly. If the cutting blade
still rotates when the engine is idling, have your
dealer check your machine and make proper
adjustments or repairs – see KombiMotor instruc‐
tion manual.
To reduce the risk of injury from
thrown objects, never operate the unit
without the proper deflector for the
machine and cutting attachment
being used.
The gearbox becomes hot during
operation. To reduce the risk of burn
injury, do not touch the gear housing.
Take special care in slippery conditions (ice, wet
ground, snow) – on slopes or uneven ground.
Watch out for obstacles: Roots and tree stumps
which could cause you to trip or stumble.
Inspect the work area: Stones, pieces
of metal or other solid objects may be
thrown more than 15 meters and
cause personal injury or damage the
cutting attachment and property (e.g.
parked vehicles, windows).
To avoid the risk of electric shock,
never use your power tool in areas
where electrical lines are laid on the
surface or buried just below the sur‐
face. Striking and damaging such
lines with the KombiTool could cause
serious or even fatal injury.
English 3 Safety Precautions and Working Techniques
4 0458-471-0121-C
Make sure you always have good balance and
secure footing.
Special care must be taken when working in diffi‐
cult, over-grown terrain.
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.
Do not touch the cutting blade while the engine
is running. If the blade becomes jammed by an
obstruction, switch off the engine immediately
before attempting to remove the obstruction –
risk of injury.
Opening the throttle while the blade is blocked
increases the load and reduces engine speed.
The clutch then slips continuously and this cau‐
ses overheating and damage to important com‐
ponents (e.g. clutch, polymer housing compo‐
nents) – and this can increase the risk of injury
from the cutting attachment moving while the
engine is idling.
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". 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.
Check the cutting blade at regular short intervals
during operation or immediately if there is a
noticeable change in cutting behavior:
–Turn off the engine. Hold the unit firmly and
press the blade into the ground to bring it to a
standstill.
–Check condition and tightness, look for cracks.
–Replace a damaged blade immediately, even
if it has only superficial cracks.
Clean the cutting attachment and deflector at
regular intervals during operation.
–Shut down the engine.
–Wear gloves.
–Remove grass, weeds, clumps of soil, etc.
To reduce the risk of injury, shut off the engine
before changing the cutting attachment.
Do not continue using or attempt to repair a dam‐
aged or cracked blade by welding or straighten‐
ing – risk of out of balance.
This may cause parts of the cutting attachment
to come off and hit the operator or bystanders at
high speed and result in serious or fatal injuries.
If a rotating metal cutting attachment makes con‐
tact with a rock or other solid object there is a
risk of sparking which may cause easily combus‐
tible material to catch fire under certain circum‐
stances. Dry plants and scrub are also easily
combustible, especially in hot and dry weather
conditions. If there is a risk of fire, do not use
metal cutting attachments near combustible
materials, dry plants or scrub. Always contact
your local forest authority for information on a
possible fire risk.
3.6 After Finishing Work
After finishing work or before leaving the power
tool unattended: Shut off the engine.
After finishing work, clean dirt, soil and plant resi‐
due off the cutting attachment – wear gloves to
reduce the risk of injury.
Do not use grease solvents for cleaning.
After thoroughly cleaning, coat surface of metal
cutting attachments with a corrosion inhibitor.
3.7 Maintenance and Repairs
Service the machine regularly. Do not attempt
any maintenance or repair work not described in
the KombiTool and KombiEngine instruction
manuals. Have all other work performed 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 genuine 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.

The arrow on the deflector shows the direction of
rotation of the blade – see "Use".
Operate the edger only the skirt attached to the
deflector – see "Replacing the skirt".
Handle the blade correctly – see "Use".
Optimum cutting performance: at full throttle and
with uniform feed.
STIHL recommends the use of genuine STIHL
blades – see "Special accessories".
Only use deflectors or attachments which have
been approved by STIHL for this machine or
which are technically equivalent.
4 Using the Unit
239BA015 KN
Your power edger is designed to produce sharp
contoured borders around lawns and flower
beds. It will cut almost all types of grass, weeds
and soft green plants.
4.1 Preparations
If the work area is very dry, spray it lightly with
water: this softens the soil and ensures that less
dust is created. Slightly damp green plants are
easier to cut.
WARNING
Clear away all obstacles and solid objects from
the work area.
► Plan the best route for edging. Always hold
and operate your edger on the right-hand side
of your body.
4.2 Adjusting Depth of Cut

the depth of cut again and correct it if neces‐
sary.
239BA015 KN
WARNING
Do not adjust the deflector.
The deflector has been set at the factory so that
the arrow on the deflector and the open side
point away from the operator. This ensures that
cuttings and other debris are directed away from
the power tool and operator.
