are technically identical. If you have any

questions in this respect, consult your

dealer.

Use only high quality parts and

accessories. in order to avoid the risk of

accidents and damage to the machine.

STIHL recommends the use of original

STIHL tools, cutting attachments 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.

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.

Sturdy shoes with non-slip shoes are

permissible only when using mowing

heads.

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.

Always wear a hard hat during thinning

work, in high brush, and whenever there

is a risk of injury due to falling objects.

STIHL can supply a comprehensive

range of personal protective equipment.

Transporting the machine

Always stop the engine.

Carry the machine hanging on the

harness or by the shaft so that it is

balanced.

To reduce the risk of cut injuries, fit

transport guard on the cutting

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

– Safety devices (e. g., deflector for

cutting attachments, rider plate) for

damage and/or wear. Always

replace damaged parts. Do not use

the machine with a damaged

deflector or worn rider plate (if the

writing and arrows are no longer

discernible)

– Do not attempt to modify the

controls or safety devices in any

way – only work with the deflector

fitted

– Keep the handles dry and clean –

free from oil and dirt – this is

important for safe control of the

machine

– Adjust the harness and handle(s) 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!

To prepare for emergencies when using

a harness: Practice setting down the

machine quickly. To avoid damage, do

not throw the unit to the ground when

practicing.

Holding and guiding the machine

Always hold the unit firmly with both

hands on the handles.

Make sure you always have good

balance and secure footing.

For versions with bike handle

Right hand on control handle, left hand

on grip on handlebar.

For versions with loop handle

For versions with loop handle and loop

handle with barrier bar, left hand on the

loop handle, right hand on the control

handle – even if you are left-handed.

Wrap your fingers and thumbs around

the handles.

While working

Make sure you always have good

balance and secure footing.

In the event of impending danger or in

an emergency, switch off the engine

immediately by moving the slide

control/stop switch/stop button to

0 or STOP.

Within a wide area around the

workplace, there is a risk of accident by

ejected objects, therefore 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 a distance

over 15 m, 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. STIHL

recommends you have this work done

by a STIHL servicing dealer.

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!

Only work while standing on the ground,

never on a ladder or mobile elevated

work platform.

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.

Be particularly careful when working on

difficult, densely grown terrain.

When mowing in high shrubbery, under

shrubbery and hedges: Hold the cutting

tool at a working height of at least 15 cm

– avoid risks to 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

– Ensure that the cutting blades are

sharp

– Replace damaged or blunt cutting

attachments immediately, even in

the event of minor hairline cracks

Clean grass and plant residue off the

cutting attachment mounting at regular

intervals – remove any build up of

material from the cutting attachment and

deflector.

To reduce the risk of injury, shut off the

engine before replacing the cutting

attachment.

Using mowing heads

Enhance the cutting attachment

deflector with the attached parts

specified in the User Manual.

Only use the protection with properly

mounted blade to ensure that the

mowing line is restricted to the

permissible length.

Always switch off the engine to adjust

the mowing line for manually adjustable

mowing heads – risk of injury!

Misuse with mowing lines that are too

long reduces the working speed of the

engine. The constant slipping of the

clutch causes 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!

Never work with

-

out protection

suitable for the

respective

machine and cut

-

ting tool – risk of

injury by ejected

objects!

Check the work site –

rocks, metal objects etc.

may be caught up and

ejected – possibly over a

distance of 15 m – risk of

injury! – They can also

damage the cutting

attachment and other

property (e. g. parking

vehicles, windows).

The gear head becomes

hot during operation. To

reduce the risk of burn

injury, do not touch the

gear housing!

When using metal cutting attachments

STIHL recommends the use of original

STIHL metal cutting attachments. These

have been optimized for the machine

and the user’s requirements.

Metal cutting attachments rotate very

fast, generating forces acting on the

attachments and on the cuttings.

Metal cutting attachments must be

sharpened in regular intervals in

accordance with the instructions.

Unevenly sharpened metal cutting

attachments generate an imbalance

which may cause extreme loads on the

machine – risk of breakage!

Dull or improperly sharpened cutting

edges can put a higher load on the

cutting attachment and increase the risk

of injuryfrom cracked or broken parts.

After each contact of the metal cutting

attachment with hard objects (e.g.

stones, rocks, metal parts), check it for

damage (e.g. tears and deformation).

Burrs and other visible material

accumulations must be removed since

they may come loose at any time while

the machine is running and then be

ejected – risk of injury!

If a rotating metal 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 metal cutting attachments in the

vicinity of combustible materials, dried-

out plants or brushwood. It is mandatory

that you ask the responsible forestry

office about the current fire hazard.

Do not continue using or attempt to

repair damaged or cracked cutting

attachments by welding, straightening or

modifying the shape (out of balance).

Particles or pieces may come off and hit

the operator or a bystander at a high

speed – risk of most severe injuries!

To reduce the above-named risks

involved in operating a metal cutting

attachment, ensure that the diameter of

your metal cutting attachment is not too

big. Also, the attachment must not be

too heavy. It must be made of high-

quality materials and have a suitable

geometry (shape, thickness).

To reduce the risk of injury, a metal

cutting attachment not manufactured by

STIHL must not be heavier, thicker,

have a different shape or a diameter

larger than the largest metal cutting

attachment approved by STIHL for this

power tool model.

After finishing work

After finishing work or before leaving the

power tool unattended: Shut off the

engine.

Clean the cutting attachment regularly

after finishing work to remove dust, dirt,

soil and plant debris – wear gloves – risk

of injury!

Do not use any grease solvents when

cleaning.

After cleaning it thoroughly, coat the

surface of metal cutting attachments

with a corrosion-proofing agent.

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 shows the

correct direction of rotation of the cutting

attachments.

Some of the following symbols are

applied to the outside of the deflector to

indicate the approved combination of

cutting attachment and deflector.

Harness / Strap

The harness is included in the scope of

supply or available as a special

accessory.

N Use a shoulder strap.

N With the engine running, attach the

machine to the shoulder strap.

Grass cutting blades and brush knives

must always be used in combination

with a shoulder strap.

Circular saw blades must always be

used in combination with a full harness

with a quick-release system.

Mowing Head with Nylon Line

Nylon line achieves a soft cut for edging

and trimming around trees, fence posts,

etc. – less risk of damaging tree bark.

The mowing head comes with an

instruction leaflet. Refill the mowing

head with nylon line as described in the

instruction leaflet.

WARNING

To reduce the risk of serious injury,

never use wire or metal-reinforced line in

place of the nylon line.

Check the wear limit marks!

If one of the wear limit marks on the

PolyCut mowing head is worn through

(arrow): Do not continue using the

mowing head. Install a new one. There

is otherwise a risk of injury from thrown

parts of the head.

It is important to follow the maintenance

instructions for the PolyCut mowing

head.

The PolyCut can also be equipped with

mowing line in place of the polymer

blades.

The mowing head comes with

instruction leaflets. Equip the mowing

head with polymers blades or nylon line

as described in the instruction leaflets.

WARNING

Never use wire in place of the nylon

mowing line – risk of injury.

Risk of Kickout (Blade Thrust) with Metal

Cutting Attachments

WARNING

The risk of kickout is greatest when the

black area of the rotating cutting

attachment comes into contact with a

solid object.

Grass Cutting Blade

Use for grass and weeds only – sweep

the brushcutter in an arc like a scythe.

WARNING

Improper use may damage the grass

cutting blade – risk of injury from thrown

parts.

Resharpen the grass cutting blade

according to instructions when it has

dulled noticeably.

Brush Knife

For cutting matted grass, wild growth

and scrub and thinning young stands

with a stem diameter of no more than

2 cm – do not cut thicker stems – risk of

accidents.

002BA049 KN

When using metal cut

-

ting attachments there is

a risk of kickout when the

rotating blade comes into

contact with a solid object

such as a tree trunk,

branch, tree stump, rock

or similar. The machine is

thrown to the right or to

the rear – opposite to the

attachment's direction of

rotation.

002BA135 KN

000BA020 KN

FS-KM

Use the brushcutter like a scythe (sweep

it to the right and left) at ground level

when cutting grass and thinning young

stands.

To cut wild growth and scrub, lower the

brush knife down onto the growth to

achieve a shredding effect – always

keep the cutting attachment below hip

level during this process.

Exercise extreme caution when using

this method of cutting. The higher the

cutting attachment is off the ground, the

greater the risk of injury from cuttings

being thrown sideways.

Warning! Improper use of a brush knife

may cause it to crack, chip or shatter –

risk of injury from thrown parts.

To reduce the risk of injury it is essential

to take the following precautions:

– Avoid contact with stones, rocks,

pieces of metal and other solid

foreign objects.

– Never cut wood or shrubs with a

stem diameter of more than 2 cm –

use a circular saw blade for such

work.

– Inspect the brush knife at regular

short intervals for signs of damage.

Do not continue working with a

damaged brush knife.

– Resharpen the brush knife regularly

and whenever it has dulled

noticeably, and have it balanced if

necessary (STIHL recommends a

STIHL servicing dealer).

Circular Saw Blade

Suitable for cutting shrubs and trees with

a maximum stem diameter of 4 cm.

Before starting the cut, accelerate the

engine up to full throttle. Perform cut

with uniform pressure.

Use circular saw blades only with a

matching limit stop of the correct

diameter.

WARNING

To reduce the risk of blade damage,

avoid contact with stones and the

ground. Resharpen the blade properly in

good time – dull teeth may result in the

blade cracking and shattering and

causing serious injury.

When felling, maintain a distance of at

least two tree lengths from the next

felling site.

Risk of kickout

The risk of kickout is highest in the black

area of the blade: Do not use this area of

the circular saw blade for cutting.

There is also a risk of kickout when

using the lighter shaded areas of the

blade: These areas of the blade should

only be used by experienced operators

with specialized training.

STIHL recommends that you use the

non-shaded area of the circular saw

blade. Always start the cut with this area

of the blade.
