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.

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.
The machine should only be provided or
loaned to people familiar with this model
and its operation. The KombiEngine and
KombiTool User Manuals should always
be handed over with the machine.
Use the bristle brush only for sweeping
areas and paths, including uneven and
jointed surfaces, and natural stone
paving.
Use the sweeper drum assembly only
for sweeping areas and paths, moving
wet materials, such a leaves or dirt to a
central point, clearing snow and
removing standing water from solid
surfaces.
The machine must not be used for any
other purposes – risk of accidents!
Only mount accessories that are
explicitly approved for this power tool
model by STIHL or are technically
identical. If you have any questions in
this respect, consult a servicing dealer.
Special safety precautions must be observed
when working with the
sweeper drum assembly
and bristle brush.
Both user manuals (KombiEngine and KombiTool)
must be read through
attentively before using
the unit for the first time
and kept in a safe place
for future reference. Noncompliance with the user
manuals may cause serious or even fatal injury.

accessories. in order to avoid the risk of
accidents and damage to the machine.
STIHL recommends the use of original
STIHL tools and accessories. They are
specifically designed to match the
product and meet your performance
requirements.
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.

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 sturdy shoes with
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 "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 machine by the carrying
handle, sweeping attachment in front of
you, hot muffler away from your body.
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.
– Tool: correctly fitted, secure and in
perfect condition
– Both sweeping attachments must
be mounted.
– Never attempt to modify the controls
or safety devices
– Inspect the deflectors for damage
and wear. Do not operate the
machine with a damaged deflector –
replace damaged parts.
– 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 user's
body height. Observe the chapter
"Fitting the Harness"

If you use sweeping attachments,
position the gearbox so that the axle is
above the shaft.
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.
Replace damaged sweeping
attachments.
See also notes on "Before Starting" in
the user manual of the KombiEngine you
are using.

Holding and guiding the machine
Make sure you always have good
balance and secure footing.
Always hold the unit firmly with both
hands on the handles.
Right hand on control handle, left hand
on loop handle, even if you are lefthanded.
To ensure reliable control, wrap your
thumbs tightly around the control handle
and handle.
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!
The correct engine idle speed is
important to ensure that the attachment
stops moving when you let go of the
throttle trigger. Check and correct the
idle speed setting at regular intervals. If
the sweeping attachment still rotates
when the engine is idling, have your
dealer check your machine and make
proper adjustments or repairs – see
KombiEngines user manual.
Electrostatic charges may build up when
working on synthetic surfaces – risk of
electric shock and accidents!
Take special care in slippery, wet
conditions, in snow and on slopes,
uneven ground, etc. – Risk of slipping!
Watch out for obstacles: tree stumps,
roots – risk of tripping or stumbling!
Make sure you always have good
balance and secure footing.
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.
Dust, fumes and smoke
produced while working
may be hazardous to
health! If dust levels are
high, wear a suitable
respirator.
To reduce the risk of a dust explosion,
spray very dusty surfaces with water
before sweeping.
KB-KM, KW-KM
English
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.
To reduce the risk of injuryfrom thrown
objects, never operate the unit without a
properly mounted deflector designed
specifically for the unit and the
attachment.
Check the work site –
rocks, metal objects etc.
may be caught up and
ejected – risk of injury!
Special care must be taken when
working in overgrown terrain.
When clearing leaves, take care not to
harm small animals.
Check the sweeping attachments at
regular short intervals during operation
or immediately if there is a sudden
change in behavior:
– Shut off the engine, hold the
machine securely.
– Check condition and proper
mounting.
– Replace damaged sweeping
attachments immediately.
Before you leave the machine: Shut the
engine off.
Regularly clean the cutting attachment
mounting and remove any blockages
and material that has accumulated
between the sweeping attachments or
around the deflector.
To reduce the risk of injury, shut off the
engine before changing attachments.
Maintenance and Repairs
Only carry out the maintenance
operations and repairs described in the
KB-KM, KW-KM KombiTool and
KombiEngine instruction manuals. All
other repairs must be performed by an
authorized STIHL service shop.
Only use original STIHL replacement
parts for maintenance and repairs.
Using replacement parts from other
manufacturers may result in damage to
the machine or personal injury.
Never attempt to modify the sweeping
attachments in any way. You may be
putting your own safety at risk.
Shut off the engine
– before carrying out any maitenance
or repair work
– before removing and installing
sweeping attachments
– before rectifying problems.
Store the power tool as described in the
instruction manuals – see chapter on
"Storing the Machine".
