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 precautions 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 understand 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-compliance with the user
manuals may cause serious or even fatal injury.

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 freedom 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-fitting safety glasses in
accordance with European 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 resistant 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
the drive tube.
Do not touch hot parts of the machine risk of burn injury!
By vehicle: When transporting in a
vehicle, properly secure your machine to
prevent turnover, 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:
– 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.

Always hold the unit firmly with both
hands on the handles.
For versions with bike handle
7
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 hydrocarbons and benzene.
Never run the engine
indoors or in poorly ventilated 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.
