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.

KombiSystem Guide to Using this Manual Safety Precautions and
Working Techniques
Some special safety pre-
cautions must be
observed to reduce the
risk of personal injury
when operating this
power tool because of the
very high speed of its cut-
ting attachment.
Both user manuals (Kom-
biEngine and KombiTool)
must be read through
attentively before using
the unit for the first time
and kept in a safe place
for future reference. Non-
compliance with the user
manuals may cause seri-
ous or even fatal injury.

STIHL recommends the use of genuine
STIHL tools and accessories. They are
specifically designed to match the
product and meet your performance
requirements.
The guard provided with your machine
may not protect the operator from all
foreign objects (gravel, glass, wire etc.)
ejected by the revolving cutting
attachment. Ejected objects may also
ricochet and strike the operator.
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 high-pressure washer to
clean the power tool. The solid jet of
water may damage parts of the unit.
Clothing and equipment
Wear proper protective clothing and
equipment.
Do not wear clothing which could
become trapped in wood, brush or
moving parts of the machine. Do not
wear a scarf, necktie or jewelry. Tie up
and confine long hair above your
shoulders.
WARNING
Wear face protection and make sure it is
a good fit. Face protection alone is not
sufficient to protect the eyes.
Wear "personal" sound protection, e.g.
ear defenders.
STIHL can supply a comprehensive
range of personal protective equipment.
Transporting the machine
Always stop the engine.
Carry the unit properly balanced by the
shaft or loop handle.
By vehicle: When transporting in a
vehicle, properly secure your machine to
prevent tipping over, damage and fuel
spillage.
Before starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the
KombiEngine and KombiTool user
manuals:
–Use only an approved combination
of cutting attachment, deflector,
handle and harness. All parts must
be assembled properly and
securely
–Check cutting attachment for
correct and secure assembly and
good condition
–Check safety devices (e. g.,
deflector for cutting attachments) for
damage and/or wear. Always
replace damaged parts. Never
operate the unit with a damaged
deflector
–Never attempt to modify the controls
or safety devices.
–Keep the handles dry and clean –
free from oil and dirt – this is
important for safe control of the
machine
–Adjust harness and handle to suit
your height and reach. Observe the
chapter "Fitting the Harness"
To reduce the risk of personal injury, do
not operate your power tool if it is
damaged or not properly assembled!
Clothing must be robust
but allow complete free-
dom of movement. Wear
close-fitting clothes such
as a boiler suit, not a
loose jacket.
Wear sturdy shoes with
non-slip soles.
To reduce the risk of eye
injuries, wear close-fit-
ting safety glasses in
accordance with Euro-
pean Standard EN 166.
Make sure the safety
glasses are a snug fit.
Wear sturdy protective
gloves made of a resist-
ant material (e. g.
leather).

To prepare for emergencies when using
a harness: Practice setting down the
machine quickly. To avoid damage, do
not throw the machine to the ground
when practicing.
See also notes on "Before Starting" in
the user manual of the KombiEngine you
are using.
Holding and guiding the machine
Always hold the unit firmly with both
hands on the handles.
On units with a loop handle and barrier
bar, left hand on loop handle, right hand
on control handle, even if you are left-
handed.
Make sure you always have a firm and
secure footing.
While working
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the slide control
/ stop switch/button to 0or STOP.
There is a risk of accident from ejected
objects within a wide area around the
working space, so you must ensure that
there is no-one within a 15 m radius of
the machine. This distance must also be
maintained in relation to objects
(vehicles, window panes) – risk of
property damage! Even at distances
beyond 15 m, the danger cannot be
ruled out.
Check that the engine is properly idling
so that the cutting tool will not continue
rotating after you release the throttle
trigger. Check and correct the idle speed
setting at regular intervals. If the
attachment still rotates when the engine
is idling, have your dealer check your
machine and make proper adjustments
or repairs – see KombiEngine user
manual.
Take special care in slippery conditions
– damp, snow, ice, on slopes or uneven
ground!
Watch out for obstacles: tree stumps,
roots – risk of tripping or stumbling!
Make sure you always have a firm and
secure footing.
Never operate your power tool with one
hand.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Take breaks when you start getting tired
or feeling fatigue – risk of accidents!
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Proceed with caution, do not put
others in danger.
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. Never use
a power tool that is no longer safe to
operate. In case of doubt, contact a
dealer.

15m (50ft)
Deflector may be
used with mowing
heads. Do not use
metal cutting
attachments – risk
of injury.
To reduce the risk
of injuryfrom
thrown objects,
never operate the
unit without the
proper deflector for
the type of cutting
attachment being
used.

FSB-KM

Be particularly careful when working on
difficult, densely grown terrain.
When cutting tall scrub, under bushes
and hedges: Keep cutting attachment at
a minimum height of 15 cm to avoid
harming small animals.
Examine the cutting attachment
periodically at short intervals and as
soon as you note any noticeable
changes:
–Turn off the engine, hold the device
securely, press the cutting
attachment against the ground to
stop it
–Check condition and secure fitting;
watch out for cracks
–Immediately replace defective
cutting tools, also in the event of
minor hairline cracks
Clean grass and plant residue off the
cutting attachment mounting at regular
intervals – remove any accumulated
material from the cutting attachment and
deflector.
To reduce the risk of injury, shut off the
engine before replacing the cutting
attachment.
After finishing work or before leaving the
power tool unattended: Shut off the
engine.
Never continue using or attempt to
repair damaged or cracked cutting
attachments.
Particles or pieces may come off and hit
the operator or a bystander at a high
speed – risk of very severe injuries!
If a rotating cutting attachment touches a
rock or another hard object, sparks may
be generated which may possibly ignite
combustible materials. Also dried-out
plants and brushwood are combustible,
above all in hot and dry weather. If there
is a risk of fire, do not use cutting
attachments in the vicinity of
combustible materials, dried-out plants
or brushwood. It is mandatory that you
ask the responsible forestry office about
current fire hazards.
Only use a deflector with a properly fitted
blade, which limits the mowing line to the
permissible length.
For manually adjustable mowing heads,
always switch off the engine before
adjusting the mowing line – risk of injury!
Misuse with mowing lines that are too
long reduces the working speed of the
engine. The constant slipping of the
clutch can cause overheating and
damage to important components (e.g.
clutch, plastic housing parts) – e.g. due
to the cutting attachment rotating during
idling – risk of injury!
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 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 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.
Symbols on Deflectors
An arrow on the deflector (inside and
outside) shows the correct direction of
rotation of the cutting attachments.
Check the work site –
rocks, metal objects etc.
could get caught up and
ejected – potentially
beyond a distance of
15 m – risk of injury! Such
objects can also damage
the cutting attachment
and other property (e.g.
parked vehicles,
windows).

Shoulder strap
The power tool may be used without a
shoulder strap. Shoulder strap and
carrying ring are special accessories.
NWith the engine running, attach the
machine to the shoulder strap.
Mowing Head with Nylon Lines
Nylon line achieves a soft cut for edging
and trimming around fence posts, trees,
etc. – less risk of damaging tree bark.
WARNING
To reduce the risk of injury, never use
steel wire in place of the nylon cutting
line.
STIHL PolyCut 6-3 Mowing Head with
Polymer Blades
For mowing unobstructed edges of
meadows (without posts, fences, trees
or similar obstacles).
It is important to follow the maintenance
instructions for the Polycut mowing
head.
Check the wear limit marks!
Wear limit marks are integrated in the
base of the PolyCut.
