Safety Precautions and
Working Techniques
Because a KombiEngine
equipped with a power
scythe KombiTool is a
high-speed, fast-cutting
power tool with sharp cutting blades, special
safety precautions must
be observed to reduce
the risk of personal injury.
It is important that you
read, fully understand
and observe the following
safety precautions and
warnings. Read the
instruction manuals and
the safety precautions of
your KombiEngine and
KombiTool periodically.
Careless or improper use
may cause serious or
fatal injury.
Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable local safety regulations,
standards and ordinances.
WARNING
Do not lend or rent your power tool
without the instruction manuals of your
KombiEngine and KombiTool. Be sure
that anyone using it understands the
information contained in these manuals.
WARNING
The use of this machine may be
hazardous. If the cutting tool comes in
contact with your body, it will cut you.
Use your KombiEngine equipped with
the power scythe KombiTool only for
cutting grass, weeds, hedges, shrubs,
scrub, bushes and similar material.
WARNING
Do not use it for other purposes, since
misuse may result in personal injury or
property damage, including damage to
the machine.
WARNING
Minors should never be allowed to use
this power tool. Bystanders, especially
children, and animals should not be
allowed in the area where it is in use.
WARNING
To reduce the risk of injury to bystanders
and damage to property, never let your
power tool run unattended. When it is
not in use (e.g. during a work break),
shut it off and make sure that
unauthorized persons do not use it.
Most of these safety precautions and
warnings apply to the use of all STIHL
power scythes. Different models may
have different parts and controls. See
the appropriate section of your
KombiEngine and KombiTool instruction
manuals for a description of the controls
and the function of the parts of your
model.
Safe use of a power tool involves
1. the operator
2. the power tool
3. the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol, etc.) which might impair vision,
dexterity or judgment. Do not operate
this machine when you are fatigued.
WARNING
Be alert – if you get tired, take a break.
Tiredness may result in loss of control.
Working with any power tool can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
this machine.
Proper Clothing
WARNING
To reduce the risk of injury, the operator
should wear proper protective apparel.
FH-KM

English
WARNING
To reduce the risk of
injury to your eyes never
operate your power tool
unless wearing goggles
or properly fitted protective glasses with
adequate top and side
protection complying with
ANSI Z87 "+" (or your
applicable national standard). To reduce the risk of
injury to your face STIHL
recommends that you
also wear a face shield or
face screen over your
goggles or protective
glasses.
Wear an approved safety
hard hat to reduce the
risk of injury to your head
when there is a danger of
head injuries.
Power tool noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
protect your hearing.
Continual and regular
users should have their
hearing checked
regularly.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Always wear heavy duty
work gloves (e.g. made of
leather or other wear
resistant material) when
handling the cutting
attachment. Heavy-duty,
nonslip gloves improve
your grip and help to protect your hands.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs. Do not wear
shorts, sandals or go
barefoot.
Avoid loose-fitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become caught on branches,
brush or the moving parts of the unit.
Secure hair so it is above shoulder level.
Good footing is very
important. Wear sturdy
boots with nonslip soles.
Steel-toed safety boots
are recommended.
For further instructions on proper
clothing see the safety precautions in
the instruction manual of the
KombiEngine you are using.
THE POWER TOOL (KOMBIENGINE
EQUIPPED WITH POWER SCYTHE
KOMBITOOL)
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts."
WARNING
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL KombiEngine
model are authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
If this 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. Check in particular that
the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
THE USE OF THE POWER TOOL
(KOMBIENGINE EQUIPPED WITH
POWER SCYTHE KOMBITOOL)
Transporting the Power Tool
WARNING
To reduce the risk of injury from blade
contact, never carry or transport your
power tool with the cutting blades
moving.
4
FH-KM
English
002BA254 KN
WARNING
Always switch off the engine and fit the
scabbard over the cutting blades before
transporting the power tool over long
distances.
It may be carried only in a horizontal
position. Grip the shaft in a manner that
the machine is balanced horizontally.
Keep the hot muffler away from your
body and the cutting attachment behind
you.
WARNING
To reduce the risk of burn injury, do not
touch hot parts of the machine and the
gear housing when they are hot.
WARNING
When transporting it in a vehicle,
properly secure it to prevent turnover,
fuel spillage and damage to the unit.
On machines with an adjustable cutter
bar: Make sure the cutter bar is secured
in position. See chapter in this
instruction manual entitled "Adjusting
the Cutter Bar." On machines with a
transport position: Move cutter bar to
transport position and secure.
Before Starting
WARNING
Always check your power tool for proper
condition and operation before starting.
Never attempt to modify the controls or
safety devices.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
WARNING
The cutting attachment must be properly
tightened and in safe operating
condition. Inspect for loose parts (nuts,
screws, etc.) and for cracked, bent,
warped or damaged blades. Regularly
check the condition of the cutting blades
– with the engine stopped! Replace
damaged cutting blades before using
the power tool. Always keep blades
sharp.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
STIHL recommends that you always
spray the cutting blades with STIHL
resin solvent before starting work – with
the engine stopped! You can obtain this
protective spray from your dealer. Apply
generously.
Adjust harness and hand grip to suit
your size before starting work. To be
better prepared in case of an
emergency, practice releasing the unit
from the harness as quickly as possible.
Starting
On machines with an adjustable cutter
bar: Secure the cutter bar in the starting
position as described in the chapter
"Starting / Stopping the Engine." If this
starting position is not the desired
cutting position, you will then need to
carefully adjust the machine to the
desired position once the engine has
returned to idle and the blades are no
longer moving.
On machines with a defined transport
position (cutter bar folded against the
drive tube): Never start the machine in
the transport position, since the blades
are not engaged in that position and you
therefore cannot visually check to see
that they will be stopped at idle when
you start to adjust the cutter bar to the
desired cutting position (where the
blades are engaged).
Start the engine at least 10 feet (3 m)
from the fueling spot, outdoors only.
For specific starting instructions, see the
appropriate section of your
KombiEngine and KombiTool manuals.
Place the power tool on firm ground or
other solid surface in an open area.
Maintain good balance and secure
footing.
WARNING
To reduce the risk of injury from loss of
control, do not attempt to "drop start"
your power tool.
FH-KM
5
English
WARNING
To reduce the risk of injury from loss of
control, be absolutely sure that the
cutting tool is clear of you and all other
obstructions and objects, including the
ground, because when the engine starts
at starting-throttle, engine speed will be
fast enough for the clutch to engage and
move the blades on the cutting tool.
Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to
idle.
With the engine running only at idle,
attach the power tool to the spring hook
of your harness (see appropriate
chapter of this manual).
WARNING
Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
See also the Safety Precautions on
Starting in the instruction manual of your
KombiEngine.
During Operation
Holding and Controlling the Power Tool
Always hold the unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
around the handles.
Models with loop handle
Right hand on control handle, left hand
on loop handle on drive tube, even if you
are left-handed. Wrap your fingers and
thumbs around the handles.
Models with handle hose
Right hand on control handle, left hand
on handle hose on drive tube, even if
you are left-handed. Wrap your fingers
and thumbs around the handles.
WARNING
Never attempt to operate
your power tool with one
hand. Loss of control of
the power tool resulting in
serious or fatal injury may
result. To reduce the risk
of cut injuries, keep
0000-GXX-1677-A00000-GXX-1678-A0
hands and feet away
from the cutting tool.
Never touch a moving
cutting tool with your
hand or any other part of
your body.
WARNING
Do not overreach. Keep proper footing
and balance at all times. Special care
must be taken in slippery conditions (wet
ground, snow) and in difficult, overgrown
terrain. Watch for hidden obstacles such
as tree stumps, roots and ditches to
avoid stumbling. For better footing, clear
away fallen branches, scrub and
cuttings. Be extremely cautious when
working on slopes or uneven ground.
WARNING
To reduce the risk of injury from loss of
control, never work on a ladder, in a tree
or any other insecure support. Never
hold the machine above shoulder
height.
Working Conditions
Operate and start your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.

WARNING
If the vegetation being cut or the
surrounding ground is coated with a
chemical substance (such as an active
pesticide or herbicide), read and follow
the instructions and warnings that
accompanied the substance at issue.
WARNING
Inhalation of certain
dusts, especially organic
dusts such as mold or
pollen, can cause susceptible persons to have
an allergic or asthmatic
reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. Control dust at the source
where possible. Use good work
practices, such as operating the unit so
that the wind or operating process
directs any dust raised by the power tool
away from the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust
("particulate matter"). When the
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH /
MSHA for the type of dust encountered.
Operating Instructions
WARNING
Do not operate your power tool using the
starting throttle lock, as you do not have
control of the engine speed.
In the event of an emergency, switch off
the engine immediately – move the slide
control / stop switch / momentary stop
switch to 0 or STOP.
See section of your KombiEngine
instruction manual on the proper use of
the slide control / stop switch /
momentary stop switch.
WARNING
The cutting blades continue to move for
a short period after the throttle trigger is
released.
Accelerating the engine while the blades
are blocked increases the load and will
cause the clutch to slip continuously.
This may result in overheating and
damage to important components (e.g.
clutch, polymer housing components) –
which can then increase the risk of injury
from the blades moving while the engine
is idling.
WARNING
On units with an adjustable cutter bar:
Carefully adjust the cutter bar to the
desired cutting position.To reduce the
risk of injury, never touch the cutting
blades while making adjustments. Only
adjust the cutter bar when the blades are
no longer moving.
WARNING
The power tool
has a large range.
In order to reduce
the risk of personal or even fatal
injury to bystanders from falling
objects or inadvertent contact
with the moving
cutting blades of
your power tool
always keep
bystanders at least
50 feet (15 m)
away when the
power tool is
running.
Stop the engine immediately if you are
approached.
WARNING
Before you start work, examine the area
where you will be working for stones,
glass, fence wire, metal, trash or other
solid objects which could damage the
cutting blades.
Take particular care when cutting next to
wire fences. Do not touch the wire with
the cutting blades. When working close
to the ground, make sure that no sand,
grit or stones get between the cutting
blades.
Striking solid foreign objects such as
stones, fence wire or metal could
damage the cutting attachment and may
cause blades to crack, chip or break.
STIHL does not recommend the use of
FH-KM
7
English
your power tool when cutting in areas
where the blades could contact such
objects.
WARNING
Observe the cutting blades at all times –
do not cut any areas that you cannot
see.
DANGER
Your power tool is not
insulated against electric
shock. To reduce the risk
of electrocution, never
operate this power tool in
the vicinity of any wires or
cables (power, etc.)
which may be carrying
electric current.
WARNING
If the cutting tool becomes clogged or
stuck, always shut off the engine and
make sure the cutting tool has stopped
before cleaning. Grass, weeds, etc.
should be cleaned off the cutting tool at
regular intervals.
Check the cutting blades at regular short
intervals during operation, or
immediately if there is a noticeable
change in cutting behavior:
– Shut off the engine.
– Wait until the cutting blades have
come to a complete standstill.
– Check condition and tightness, look
for cracks.
– Check sharpness.
– Replace damaged or dull cutting
tools immediately, even if they have
only superficial cracks.
WARNING
The gearbox becomes
hot during operation. To
reduce the risk of burn
injury, do not touch the
gear housing when it is
hot.
MAINTENANCE, REPAIR AND
STORING
WARNING
Always stop the engine and make sure
that the cutting attachment is stopped
before doing any maintenance or repair
work or cleaning the power tool. Do not
