It is important that you
read, fully understand
and observe the following
safety precautions and
warnings. Read the
instruction manuals and
the safety precautions of
your MultiEngine and
MultiTool periodically.
Careless or improper use
may cause serious or
fatal injury.
Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable local safety regulations,
standards and ordinances.
WARNING
Do not lend or rent your power tool
without the instruction manuals of your
MultiEngine and MultiTool. Be sure that
anyone using it understands the
information contained in these manuals.
WARNING
The use of this machine may be
hazardous. When it comes in contact
with solid foreign objects such as rocks
or bits of metal, it may fling them directly
or by ricochet in the direction of
bystanders or the operator. Striking such
objects could damage the MultiTool.
Thrown objects may result in serious or
fatal injury to the operator or bystanders.
Use your MultiEngine equipped with the
KW-MM PowerSweep MultiTool only for
moving wet materials, such as leaves or
dirt, clearing snow and removing
standing water from solid surfaces.
Use the KB-MM Bristle Brush MultiTool
only for sweeping areas and paths,
including uneven and jointed surfaces,
and natural stone paving.
WARNING
Do not use it for other purposes, since
misuse may result in personal injury or
property damage, including damage to
the machine.
WARNING
Minors should never be allowed to use
this power tool. Bystanders, especially
children, and animals should not be
allowed in the area where it is in use.
WARNING
To reduce the risk of injury to bystanders
and damage to property, never let your
power tool run unattended. When it is
not in use (e.g. during a work break),
shut it off and make sure that
unauthorized persons do not use it.
Most of these safety precautions and
warnings apply to the use of all STIHL
power tools. Different models may have
different parts and controls. See the
appropriate section of your MultiEngine
and MultiTool instruction manuals for a
description of the controls and the
function of the parts of your model.
Safe use of a power tool involves
1. the operator
2. the power tool
3. the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol, etc.) which might impair vision,
dexterity or judgment. Do not operate
this machine when you are fatigued.
WARNING
Be alert – if you get tired, take a break.
Tiredness may result in loss of control.
Working with any power tool can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
this machine.
Proper Clothing
WARNING
To reduce the risk of injury, the operator
should wear proper protective apparel.

the rotating MultiTool.
WARNING
To reduce the risk of injury from loss of
control, be absolutely sure that the
MultiTool is clear of you and all other
obstructions and objects, including the
ground, because when the engine starts
at starting-throttle, engine speed will be
fast enough for the clutch to engage and
move the MultiTool. This may cause the
power tool to move toward the operator.
Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to
idle.

around the handles, keeping the
handles cradled between your thumb
and forefinger. Keep your hands in this
position to have your power tool under
control at all times.
WARNING
Never attempt to operate
your power tool with one
hand. Loss of control of
the power tool may result
in serious or fatal injury.
To reduce the risk of
injury, keep hands and
feet away from the
MultiTool. Never touch a
moving MultiTool with
your hand or any other
part of your body.
WARNING
Do not overreach. Keep proper footing
and balance at all times. Special care
must be taken in slippery conditions (wet
ground, snow) and in difficult, overgrown
terrain. Watch for hidden obstacles such
as tree stumps, roots and ditches to
avoid stumbling. For better footing, clear
away scrub and cuttings. Be extremely
cautious when working on slopes or
uneven ground.
Operate the power tool only at a normal
walking pace.
WARNING
To avoid the risk of injury from contact
with the rotating attachment, be
