The STIHL interchangeable attachment may be
mounted to different STIHL power tools.
This includes KombiAttachmentEngines in some
markets. In these markets the KombiAttachmen‐
tEngines and interchangeable attachments are
part of the KombiAttachmentSystem.
The approved power tool models are listed in the
chapter on "Approved Basic Power Tools".
In this instruction manual the functional unit
formed by the basic power tool and interchange‐
able attachment is referred to as the power tool.
Therefore, the separate instruction manuals for
the basic power tool and attachment 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.

pliance with the user manuals may
cause serious or even fatal injury.
Lend or rent your power tool only to persons who
are familiar with this model and its operation. Do
not lend or rent your power tool without the User
Manuals for the basic power tool and tool attach‐
ment.
Use the cultivator only for tilling already cultiva‐
ted, packed or loose soil, furrowing and working
in mulches.
The machine must not be used for any other pur‐
poses – risk of accident!
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. Oth‐
erwise, there is a risk of accidents and damage
to the machine.
STIHL recommends the use of original STIHL
replacement parts, rotor blades and accessories.
They are specifically designed to match the prod‐
uct 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.
3.1 Clothing and Equipment
Wear proper protective clothing and equipment.
Clothing must be sturdy but allow
complete freedom of movement.
Wear close-fitting clothes such as a
boiler suit, not a loose jacket.
Do not wear clothing which could become trap‐
ped in wood, brush or moving parts of the
machine. Do not wear a scarf, necktie or jewelry.
Tie up and secure long hair above your should‐
ers.
Wear safety boots with steel toe caps
and non-slip soles.
WARNING
To reduce the risk of eye injuries,
wear close-fitting safety glasses in
accordance with European Standard
EN 166. Make sure the safety
glasses are a snug fit.
Wear face protection and make sure it is a good
fit. Face protection alone is not sufficient to pro‐
tect the eyes.
Wear "personal" sound protection, e.g. ear
defenders.
Wear sturdy protective gloves made
of a resistant material (e. g. leather).
STIHL offers a comprehensive range of personal
protective equipment.
3.2 Transporting the machine
Always stop the engine.
Carry the power tool hanging from the shoulder
strap or properly balanced by the drive tube.
Do not touch hot parts of the machine – risk of
burn injury!
By vehicle: When transporting in a vehicle, prop‐
erly secure your machine to prevent turnover,
damage and fuel spillage.
3.3 Before starting
Check that your power tool is properly assem‐
bled and in good condition. Refer to the appropri‐
ate chapters in the User Manuals for the basic
power tool and tool attachment.
–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 deflec‐
tor 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"
The power tool must only be operated when it is
in good operating condition – Risk of accident!
3 Safety Precautions and Working Techniques English
0458-504-0121-B 3

To prepare for emergencies when using a har‐
ness: Practice setting down the machine quickly.
To avoid damage, do not throw the machine to
the ground when practicing.
3.4 Holding and Guiding the Tool
Make sure you always have a firm and secure
footing.
Always hold the unit firmly with both hands on
the handles.
3.4.1 For versions with bike handle
002BA055 KN
Right hand on control handle, left hand on grip
on handlebar.
3.4.2 For versions with loop handle
002BA080 KN
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 han‐
dles.
3.5 While Working
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the slide control / stop switch/button to
0 or STOP.
7
Do not allow any other persons within 5 meters
of your own position. Risk of injury due to ejected
objects.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 rotor blades - risk of injury!
As soon as the engine starts running,
the power tool generates toxic
exhaust gas. These gases may be
odorless and invisible and may con‐
tain unburned hydrocarbons and ben‐
zene. Never run the engine indoors or
in poorly ventilated locations, even if
your model is equipped with a cata‐
lytic converter.
Arrows on the rotor 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 no longer rotate once the throt‐
tle trigger has been released. Check and correct
the idle speed setting at regular intervals. If the
rotor blades still rotate when the engine is idling,
have your dealer check your machine and make
proper adjustments or repairs – see User Manual
of basic power tool.
To reduce the risk of injury from thrown objects,
do not operate the unit without a suitable deflec‐
tor designed specifically for the unit and the
attachment.
Take special care in slippery conditions – damp,
snow, ice, on slopes or uneven ground!
English 3 Safety Precautions and Working Techniques
4 0458-504-0121-B

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 electrocution,
never use your power tool in areas
where electrical lines are laid on the
surface or buried just below the sur‐
face.Striking and damaging such
lines with the attachment could cause
serious or even fatal injury.
Make sure you always have a firm and secure
footing.
Operate your power tool at normal walking pace
only.
Take particular care when working close to fen‐
ces, 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
ear protection because your ability to hear warn‐
ings (shouts, alarms, etc.) is impaired.
Take breaks when you start getting tired or feel‐
ing 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 impor‐
tant 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 dam‐
aged or cracked rotor blades by welding or
straightening – risk of deformation (out of bal‐
ance).
Particles or pieces may come off and hit the
operator or a bystander at a high speed – risk of
most severe injuries!
3.6 After Finishing Work
After finishing work or before leaving the power
tool unattended: Shut off the engine.
After finishing work, regularly clean dust, dirt, soil
and plant residue off the attachment – wear
gloves to reduce the risk of injury!
Do not use any grease solvents when cleaning.
After thoroughly cleaning, coat metal surface of
attachments with a corrosion inhibitor.
3.7 Maintenance and Repairs
Service the machine regularly. Do not attempt
any maintenance or repair work not described in
the instruction manuals of the basic power tool
and attachment. Have all other work performed
by a servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized 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

power tool. 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.

4.1 General Information
381BA003 KN
4.2 Preparation
► Starting the engine
► Fitting the harness
4.3 Working technique
You can work with your cultivator in the for‐
ward (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 for‐
wards motion is particularly suitable for loosening
packed soil.
The rotor blades may only be mounted and oper‐
ated in one position. Arrows on the rotor blades
show the required direction of rotation.
WARNUNG
The cultivator moves away from the user during
work. Always ensure a secure footing to be able
to control the cultivator.
4.4 Example applications
►Breaking up soil
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 gar‐
den). 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.
English 4 Using the Unit
6 0458-504-0121-B

►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.
►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.
►Trenching or furrowing
Walk slowly backward and pull the cultivator to
create the furrow required. Repeat as necessary
to obtain deeper furrows.
4.4.1 Cleaning the Rotor Blades
Parts of plants, e.g. roots, can become tightly
wrapped around or between the rotor blades dur‐
ing 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
WARNUNG
Rotor blades are sharp edged. Wear gloves
while cleaning.
