Equipment and features
This instruction manual may refer to
several models with different
features. Components that are not
installed on all models and related
applications are marked with an
asterisk (*). Such components may
be available as special accessories
from your STIHL dealer.
Engineering improvements
STIHL’s philosophy is to continually
improve all of its products. As a result,
engineering changes and improvements
are made from time to time. If the
operating characteristics or the
appearance of your machine differ from
those described in this manual, please
contact your STIHL dealer for
assistance.
Therefore some changes, modifications
and improvements may not be covered
in this manual.
Special safety
precautions must be
taken when working with
this power tool because of
the very high speed of the
cutting tool.
It is important that you
read and understand both
instruction manuals
(CombiEngine and
CombiTool) before using
the unit for the first time.
Keep the manuals in a safe place for
future reference.
Non-observance of the safety
precautions in the instruction manuals
may cause serious or even fatal injury.

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 to operate your
power tool or attend a special course of
training in power tool operation.
Minors should never be allowed to use a
power tool.
Bystanders, especially children, and
animals should not be allowed in the
area where a power tool is in use.
When the machine is not in use (work
break), shut it off so that it does not
endanger others and secure it against
unauthorized use.
The power tool user is responsible for
avoiding injury to third parties or damage
to their property.
Do not lend or rent your power tool
without the CombiEngine and
CombiTool instruction manuals. Be sure
that anyone using your power tool

Safety Precautions and
Working Techniques

4
English
FSB-KM
Do not operate the power tool if you are
under the influence of any substance
(drugs, alcohol) which might impair
vision, dexterity or judgment.
Depending on the cutting tool fitted, use
your power tool only for mowing grass,
cutting wild growth and similar materials.
Do not use your power tool for any other
purpose since this may result in
accidents or damage to the machine.
Never attempt to modify your power tool
in any way since this may also result in
accidents or damage to the machine.
Only mount cutting tools and
accessories that are explicitly approved
for this power tool model by STIHL or
are technically identical. If you have any
questions in this respect, consult a
servicing dealer.
To reduce the risk of accidents or
damage to the machine, use only high
quality tools and replacement parts.
STIHL recommends the use of STIHL
original tools and accessories. The
characteristics of these components are
specifically designed to match your
machine and meet your performance
requirements.
The deflector provided with your
machine may not protect the operator
from all foreign objects (stones, glass,
wire, etc.) thrown by the rotating cutting
tool. Thrown objects may also ricochet
and strike the operator.
Clothing and Equipment
Wear proper protective clothing and
equipment.
Clothing must be sturdy
but allow complete
freedom of movement.
Wear snug-fitting clothing,
e.g. an overall and jacket
combination, do not wear
a work coat.
Avoid loose-fitting jackets, scarves,
neckties, jewellery or anything that could
get caught on wood or brush or moving
parts of the machine. Tie up and confine
long hair (cap, hard hat, etc.).
Wear sturdy boots
with non-slip soles.
To reduce the risk of injury
from thrown objects,
always wear a face shield
and safety glasses.
Warning! A face shield
alone does not provide adequate eye
protection.
Wear hearing protection, e.g. ear plugs
or ear muffs.
Wear heavy-duty
gloves, preferably made
of leather.
STIHL offers a comprehensive range of
safety clothing and equipment for
personal protection.

Transporting the Power Tool
Always turn off the engine.
Carry the unit properly balanced by the
drive tube or loop handle.
By vehicle: Properly secure the power
tool to prevent turnover and damage.
Before Starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the
CombiEngine and CombiTool instruction
manuals:
– The combination of cutting tool,
deflector, handle and shoulder strap
must be approved and all parts
properly assembled.
To reduce the
risk of injury, do
not use metal
cutting tools.
– Cutting tool: Check for correct and
secure assembly and good
condition.
– Check protective devices (e.g.
deflector for cutting tool) for damage
and wear. Always replace damaged
parts. Do not operate your machine
with a damaged deflector.
– Never attempt to modify the controls
or safety devices.
– Keep the handles dry and clean,
free from oil and dirt, for safe
control.
– Adjust shoulder strap and handle(s)
to suit your height and reach.
See chapter on “Fitting the Shoulder
Strap”.
To reduce risk of accidents and personal
injury, do not operate your machine if it is
damaged or not properly assembled.
If you use a shoulder strap or full
harness: Practise removing and putting
down the machine as you would in an
emergency. To avoid damage, do not
throw the machine to the ground when
practising.
See also notes in chapter “Before
Starting” in the CombiEngine instruction
manual.

Starting the Engine
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The cutting tool must be clear
of the ground and all other obstructions
because it may begin to rotate when the
engine starts.
Your power tool is a one-person unit. To
reduce the risk of injury from thrown
objects, do not allow other persons
within a radius of 15 meters of your own
position – even when starting.
To reduce the risk of
injury, avoid contact with
the cutting tool.
Start the engine as
described in the CombiEngine and
CombiTool instruction manuals.
Note that the cutting tool
continues to rotate for a
short period after you let
go of the throttle trigger –
flywheel.
Check engine idle speed setting. The
cutting tool must not rotate when the
engine is idling with the throttle trigger
released – see CombiEngine instruction
manual.
Holding and Controlling the
Machine
Always hold the unit firmly with both
hands on the handles. Make sure you
always have good balance and secure
footing.
On loop-handled machines with barrier
bar: Left hand on loop handle, right hand
on control handle. Left-handers should
follow these instructions too.
During Operation
In the event of imminent danger or in an
emergency, switch off the engine
immediately – move the slide control /
stop switch to 0or STOP.
To reduce the risk of injury from thrown
objects, do not allow bystanders within
15 meters of your own position.
To reduce the risk of damage to
property, also maintain this distance
from other objects (vehicles, windows).
Check and correct the engine idle speed
setting regularly. If the cutting tool still
rotates when the engine is idling, have
your dealer make proper adjustments
and repairs.
Take special care in slippery conditions
– damp, snow, ice, on slopes, uneven
ground, etc.
Watch out for obstacles: Roots, tree
stumps or holes which could cause you
to trip or stumble.

Make sure you always have firm and
secure footing.
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 – ensure you do not endanger
others – stay alert at all times.
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 in particular that 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.
To reduce the
risk of personal
injury from
thrown objects,
never operate the
unit without the deflector specified for
the cutting tool being used.
Before cutting, inspect the
area for stones, pieces of
metal or other solid
objects which could be
thrown and cause serious
injury, damage the power
tool and property (e.g. parked vehicles,
windows).
Special care must be taken when
working in difficult, over-grown terrain.
When cutting high scrub, under bushes
and hedges: Keep cutting tool at a
minimum height of 15 cm so as to avoid
harming small animals (e.g.
hedgehogs).
Always shut off the engine before
leaving the unit unattended.
Check the cutting tool at regular short
intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
– Turn off the engine. Hold the
machine firmly and press the cutting
tool into the ground to bring it to a
standstill.
– Check condition and tightness, look
for cracks.
– Replace a damaged or dull cutting
tool immediately, even if it has only
superficial cracks.
Always clean grass and plant residue off
the cutting tool mounting flange –
remove blockages from around cutting
attachment and deflector.
To reduce the risk of unintentional
engine start and injury, always shut off
the engine before and remove the spark
plug boot before replacing the cutting
tool.

Never continue using or attempt to
repair damaged or cracked cutting tools.
This may cause parts of the cutting tool
to come off and hit the operator or
bystanders at high speed, and result in
serious or fatal injuries.
Use only the deflector with properly
mounted line limiter blade to ensure that
the nylon lines are automatically
trimmed to the approved length.
To reduce the risk of injury, always shut
off the engine before adjusting length of
the nylon line on manually adjustable
mowing heads.
Using the unit with over-long nylon
cutting lines increases the load on the
engine and reduces its operating speed.
This causes the clutch to slip
continuously and results in overheating
and damage to important components
(e.g. clutch, polymer housing
components). There is also a risk of
injury from the cutting tool rotating while
the engine is idling.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the CombiTool and
CombiEngine 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 authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and receive technical
information bulletins on engineering
changes.
Use only high quality replacement parts
since there is otherwise a risk of
accidents or damage to the machine. If
you have any questions in this respect,
consult a servicing dealer.
STIHL recommends you use only
original STlHL replacement parts. The
characteristics of these parts are
specifically designed to match your
machine 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.
Symbols on Deflectors
Arrows on the deflector (one inside and
one outside) show the direction of
rotation of the cutting tools.

Shoulder Strap
:Use a shoulder strap.
:Start the engine and then attach the
power tool to the shoulder strap.
:Observe all safety precautions.
The power tool may be used without
a shoulder strap. The shoulder strap
and carrying ring are special
accessories.
Mowing Head with Nylon Line
Produces a "soft" cut for edging and
trimming around trees and fence posts
– less risk of damaging tree bark.
To reduce the risk of serous injury,
never use wire in place of nylon
cutting line.
