Before Starting
Check that your power tool is properly
assembled and in good condition – refer
to appropriate chapters in the instruction
manuals:
To reduce risk of injury from MultiTool
rotating in the wrong direction, check
that position of gearbox is correct and
adjust if necessary.
See chapter on "Mounting the
MultiTool".
Correct Position of Gearbox:
(for bristle brush and PowerSweep)
The axle (1) must be above the drive
shaft (2) so that the MultiTool rotates in
the direction of the arrow (3).
Position the gearbox for sweeping
attachments (bottom illustration) so that
the axle is above the drive shaft.
See also notes on "Before Starting" in
the MultiEngine instruction manual.
– Sweeping attachments must be
correctly and securely mounted and
in good condition.
– Both sweeping attachments must
be mounted.
– Bristle brush: Mount both deflector
extensions.
– Never attempt to modify the controls
or safety devices.
– Keep the handles dry and clean for
safe control.
– Set the handlebar to the normal
operating position and tighten down
firmly with the rotary knob. See
chapter on "Adjusting the
Handlebar" in the MultiEngine
instruction manual.
Always check your power tool for proper
condition and operation before starting.

Starting the Engine
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. To reduce the risk of damage,
be sure that the sweeping attachments
are clear of the ground and all other
obstructions.
Your power tool is a one-person unit. To
reduce the risk of injury from thrown
objects or contact with the sweeping
attachment, do not allow other persons
within a radius of 5 meters of your own
position – even when starting. When the
engine is started in the START position,
the sweeping attachments begin to
rotate immediately. When starting,
always stand to one side of the machine
to avoid risk of injury from contact
with rotating tool.
Check engine idle speed setting. The
sweeping attachments must not rotate
when the engine is idling with the throttle
trigger released.
See also chapter on "Starting the
Engine" in the MultiEngine instruction
manual.
Holding and Controlling the
Power Tool
Always hold the unit firmly with both
hands on the handles.
For safe control wrap your fingers and
thumbs tightly around the control handle
and left handle.
Hold the control handle with your right
hand and left handle with your left hand.
During Operation
Note that the sweeping attachment
continues to rotate for a short period
after you let go of the throttle trigger
(flywheel effect).
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Stay alert at all times so as not to
endanger others.
Make sure you have good balance and
secure footing at all times, taking special
care in slippery conditions:
– damp, snow, ice
– on slopes, uneven ground etc.
Watch out for hidden obstacles such as
tree stumps and roots to avoid
stumbling.
To reduce the risk of a
dust explosion, spray
very dusty surfaces with
water before sweeping.
Always operate the power
tool in such a way that the sweeping
attachments cannot become jammed or
blocked.
Do not operate using the starting throttle
lock as you do not have control of the
engine speed.
To reduce the risk of injury from contact
with the sweeping attachment, do not
allow bystanders within 5 m of your
own position.

English
To reduce the risk of injury, keep your
hands and feet well away from the
attachment. Never touch a rotating
attachment.
Always stand behind the deflector or to
one side of the machine during work –
never in front of the attachments
Before starting work,
inspect the area for solid
objects such as stones
and pieces of metal.
Sweeping attachments could throw
objects of this kind and cause serious
injury, damage property (e.g. parked
vehicles, windows) and the sweeping
attachments themselves.
Be particularly cautious when working is
overgrown terrain.
When clearing leaves, take care not to
harm small animals (e.g. hedgehogs).
The correct engine idle speed is
important to ensure that the sweeping
attachments stop rotating when you let
go of the throttle trigger.
Check and correct the idle speed setting
at regular intervals – see MultiEngine
instruction manual. If the sweeping
attachments still rotate, have your
STIHL dealer check your power tool and
make proper adjustments or repairs.
Clean away any dirt and debris that has
accumulated between the sweeping
attachments, in the area of the gearbox
or between the sweeping attachments
and the deflector – always turn off the
engine before performing any cleaning
work.
To reduce the risk of unintentional
engine start and injury, always shut off
the engine and remove the spark plug
boot before changing attachments
See also notes on "During Operation" in
the MultiEngine instruction manual.
When the machine is not in use, put it
down so that it does not endanger
others. Protect it from unauthorized use
(e.g. by children).
General Precautions
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Keep within calling distance of others in
case help is needed.
Maintenance and Repairs
Do not attempt any maintenance or
repair work not described in the KB-MM,
KW-MM MultiTool and MultiEngine
instruction manuals.
Have all other worked performed by your
STIHL servicing dealer.
Only use original STlHL replacement
parts for repairs to the machine. The use
of replacement parts from other
manufacturers may result in damage to
the machine and increase the risk of
injury.
Never attempt to modify your power tool
in any way as this could result in serious
injury.
:Shut off the engine:
– Before performing any maintenance
or repair work.
– Before mounting or removing the
sweeping attachments.
– Before rectifying faults.
