KombiSystem Guide to Using this Manual Safety Precautions and

Working Techniques

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.

Pictograms

All the pictograms attached to the
machine are shown and explained in this
manual.

WARNING

Warning where there is a risk of an
accident or personal injury or serious
damage to property.

NOTICE

Caution where there is a risk of
damaging the machine or its individual
components.

Engineering improvements

STIHL's philosophy is to continually
improve all of its products. For this
reason we may modify the design,
engineering and appearance of our
products periodically.

Therefore, some changes, modifications
and improvements may not be covered
in this manual.

Lend or rent your machine only to
persons who are familiar with this model
and its operation – do not lend or rent
your machine without the KombiEngine
and KombiTool user manuals.

Use the cultivator only for tilling
previously cultivated, packed or loose
soil, furrowing and working in mulches.

The machine must not be used for any
other purposes – risk of accidents!

Only mount rotor blades and
accessories that are explicitly approved
for this power tool by STIHL or 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.

Special safety precau
tions must be observed
when working with the
cultivator because its
pointed and sharp-edged
rotor blades rotate at high
speed.

Always read and and
make sure you under
stand both user manuals
(KombiEngine and
KombiTool) before using
your power tool for the
first time and keep them
in a safe place for future
reference. Non-compli
ance with the user

STIHL recommends the use of original
STIHL replacement parts, rotor blades
and accessories. They are specifically
designed to match the product and meet
your performance requirements.

The deflector on this power tool cannot
protect the operator from all objects
thrown by the blade (stones, glass, wire,
etc.). 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.

Clothing must be sturdy
but allow complete free
dom of movement. Wear
close-fitting clothes such
as a boiler suit, not a
loose jacket.

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.

-

Wear safety boots with
steel toe caps and non­slip soles.

WARNING

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 "personal" sound protection, e.g.
ear defenders.

Wear sturdy protective
gloves made of a resist
ant material (e. g.
leather).

STIHL can supply a comprehensive
range of personal protective equipment.

Transporting the machine

Always stop the engine.
Carry the power tool hanging from the

shoulder strap or properly balanced by

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:

– Rotor blades, correctly fitted, secure

and in perfect condition (clean,
moves freely, not warped)

– Inspect the deflectors for damage

and wear. Do not operate the
machine with a damaged deflector –
replace damaged parts.

– 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 carrying harness and

handles in accordance with body
height. 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 machine to the ground
when practicing.

Holding and guiding the machine

BF-KM

Make sure you always have good
balance and secure footing.

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.

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 0 or STOP.

To reduce the risk of injury from ejected
objects, do not allow any other persons
within 5 meters of your own position.
This distance must also be maintained in
relation to objects (vehicles, window
panes) – risk of property damage!

Ensure that the gear unit
and the rotor blades are
correctly attached and
aligned and avoid contact
with the chopping stars ­risk of injury!

As soon as the engine is
running, the power
machine generates toxic
exhaust gas. These
gases may be odorless
and invisible and may
contain unburned hydro

-

carbons and benzene.
Never run the engine
indoors or in poorly venti
lated locations, even if
your model is equipped
with a catalytic converter.

Arrows on the blades show the direction
of rotation. The arrows on the rotor
blades must point in the same direction
as the arrows on the gear.

Make sure the idle speed setting is
correct. The rotor blades must not rotate
when the engine is idling with the throttle
trigger released. Check and correct the
idle speed setting at regular intervals. If
the rotor blades still rotate, have your
dealer check your machine and make
proper adjustments or repairs – see
KombiEngine instruction manual.

Never work without suitable protection
for the unit and KombiTool - risk of injury
from thrown objects!

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!
Check the work site – rocks, metal

objects etc. may be caught up and
ejected – risk of injury! - and may
damage the rotor blades.

To avoid the risk of elec
trocution, never use your
power tool in areas where
electrical lines are laid on
the surface or buried just
below the surface.Strik
ing and damaging such
lines with the KombiTool
could cause serious or
even fatal injury.

Make sure you always have good
balance and secure footing.

Operate your power tool at normal
walking pace only.

Take particular care when working close
to fences, walls, stones, roots, trees and
areas of dense growth. The rotor blades
may snag –risk of injury!

Be extremely cautious when pulling the
power tool towards you because of the
risk of injury from contact with the
rotating blades.

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.

Do not touch the rotor blades while the
engine is running. If the rotor blades
become jammed by an object, switch off
the engine immediately before
attempting to remove the object – there
is otherwise a risk of injury!

Opening the throttle while the rotor
blades are blocked increases the load
and reduces engine speed. The clutch
then slips continuously and this causes
overheating and damage to important
components (e.g. clutch, polymer
housing components) – and this can
increase the risk of injury from the rotor
blades running while the engine is idling.

Check the rotor blades at regular short
intervals during operation or
immediately if there is a noticeable
change in operating behavior:

– Shut off the engine, hold the

machine securely.

– Check condition and secure fitting;

watch out for cracks

– Replace damaged rotor blades

immediately, even if they have only
superficial cracks.

Clean the rotor blades and deflector at
regular intervals during operation.

– Shut off the engine
– Use gloves
– Remove grass, weeds, clumps of

soil, etc.

Switch off the engine before changing
the rotor blades – Risk of injury!

Do not continue using or attempt to
repair damaged or cracked rotor blades
by welding or straightening – risk of
deformation (out of balance).

Particles or pieces may come off and hit
the operator or a bystander at a high
speed –

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 residue off the KombiTool – wear
gloves to reduce the risk of injury!

Do not use any grease solvents when
cleaning.

After thorough cleaning, wet the surface
of metal KombiTools with an
anticorrosive 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.

Using the Unit

General Information

Preparation

N Starting the engine
N Fitting the harness

Working techniques

You can work with your cultivator in the
forward (1) and backward (2) directions,
from left to right or vice versa (3) or in a
circular motion.

Choose the best method to suit your
purpose, i.e. this depends on the shape
and size of the area and soil conditions.

Working in an alternating backwards
and forwards motion is particularly
suitable for loosening packed soil.

0000097751_001

WARNING

The cultivator moves away from the user
during work. Always ensure a secure
footing to be able to control the
cultivator.

Example applications

N Breaking up soil

6

BF-KM

English

A few preparations are necessary before
you begin to break up soil which has
been previously tilled (e.g. last year's
vegetable or flower garden). First clear
away surface weeds and remains of
other plants as well as hard objects like
rocks, stones, bottles, pieces of wood
etc. which can be thrown up by the rotor
blades.

Hold the cultivator firmly with both hands
and till only a small area at a time to the
required depth.

Finish tilling the area by guiding the
cultivator in such a way that you leave
no footprints. Use a rake to level off the
entire area.

N Loosening soil around plants
Only loosen the surface soil around

plants. Avoid going too deep as this
could damage the shallow roots of some
plants.

To avoid any damage to the cultivator or
trees, be wary not to catch the blades on
the large roots of trees.

N Working in soil improvers
The cultivator can be used for mulching

with loam, compost, leaves, other
organic material or fertilizers.

Prepare the area by removing all old
roots, the remains of large plants and
hard objects (stones etc.). Spread the
mulch evenly on the ground.

Work in the mulch with a circular or back
and forth motion.

Finish off by leveling the area with a
rake.

N Trenching or furrowing
Walk slowly backward and pull the

cultivator to create the furrow required.
Repeat as necessary to obtain deeper
furrows.

Cleaning the Rotor Blades
Parts of plants, e.g. roots, can become

tightly wrapped around or between the
rotor blades during operation. To clean
the rotor blades:

– Switch off the cultivator and wait

until the blades come to a complete
standstill.

– Pull the hitch pins out of the axle
– Pull the rotor blades off the shaft
– Remove pieces of roots, plants and

soil

WARNING

Rotor blades are sharp edged. Wear
gloves while cleaning.
