Safety Precautions and
Working Techniques
Because a MultiEngine
equipped with a Bristle
Brush or PowerSweep
MultiTool is a powerful
tool, special safety precautions must be
observed to reduce the
risk of personal injury.
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.
KB-MM, KW-MM

English
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 suitable deflector for your power
tool will not protect the operator from all
foreign objects (stones, glass, wire, etc.)
thrown by the rotating attachment.
Thrown objects may also ricochet and
strike the operator.
Warning!
To reduce the risk of
injury to your eyes never
operate your power tool
unless wearing goggles
or properly fitted protec-
tive glasses with
adequate top and side protection complying with ANSI Z 87.1 (or your
applicable national standard).
Power tool noise may damage your
hearing. Wear sound barriers (ear plugs
or ear mufflers) to protect your hearing.
Continual and regular users should
have their hearing checked regularly.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Always wear gloves
when handling the power
tool. Heavy-duty, nonslip
gloves improve your grip
and help to protect your
hands.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs. Do not wear
shorts, sandals or go
barefoot.
Avoid loose-fitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become caught on branches,
brush or the moving parts of the unit.
Secure hair so it is above shoulder level.
Good footing is very
important. Wear sturdy
boots with nonslip soles.
For further instructions on proper
clothing see the safety precautions in
the instruction manual of the
MultiEngine you are using.
THE POWER TOOL (MULTIENGINE
EQUIPPED WITH BRISTLE BRUSH
OR POWERSWEEP MULTITOOL)
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts."
Warning!
Never modify this power tool in any way.
Only attachments supplied by STIHL
and expressly approved by STIHL for
use with the specific STIHL power tool
models are authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
If this 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. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.

carry or transport your power tool with
the MultiTool moving.
Warning!
Always switch off the engine and make
sure the MultiTool has stopped before
putting a power tool down.
Grip the power tool by the carrying
handle with the attachment facing
forward.
Warning!
When transporting it in a vehicle, properly secure it to prevent turnover, fuel
spillage and damage to the unit.
Before Starting
Warning!
Always check your power tool for proper
condition and operation before starting.
Never attempt to modify the controls or
safety devices.
Warning!
Never operate your power tool if it is
damaged, improperly adjusted or maintained, or not completely or securely
assembled.
Unfold the bike handle into the working
position and secure it with the knob (see
chapter "Adjusting the bicycle handle" of
your MultiEngine instruction manual.)
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
Warning!
To reduce the risk of injury from the
MultiTool rotating in the wrong direction,
check that the position of the gearbox is
correct and change it if necessary.
On sweeping tools (bottom illustration),
position the gearbox so that the shaft is
above the drive tube.
Use for:
– KB-MM Bristle Brush
– KW-MM PowerSweep
Warning!
The MultiTool must be properly tightened and in safe operating condition.
Inspect for loose parts (hitch pins,
screws, etc.) and for damaged parts.
Replace damaged MultiTools before
using the power tool.
Warning!
Do not attach any MultiTool to a unit
without proper installation of all required
parts. Failure to use the proper parts
may cause the attachments to fly off and
seriously injure the operator or
bystanders.

Starting
Warning!
Start the engine at least 10 feet (3 m)
from the fueling spot, outdoors only.
For specific starting instructions, see the
appropriate section of your MultiEngine
and MultiTool manuals.
Place the power tool on firm ground or
other solid surface in an open area.
Maintain good balance and secure
footing.
Warning!
Always stand to one side of the unit to
avoid the risk of injury from contact with
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.
Warning!
Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
See also the safety precautions on
Starting in the instruction manual of the
MultiEngine.
During Operation
Holding and Controlling the Power Tool
Always hold the unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
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.

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
extremely cautious when pulling the
power tool toward you.
Be extremely cautious when changing
direction with the power tool – especially
on slopes.
Warning!
To avoid the risk of injury from loss of
control, never work on steep slopes.
KB-MM Bristle Brush
KB-MM PowerSweep
Warning!
To reduce the risk of injury from loss of
control, hold and guide the machine at a
shallow angle. If the machine is held at
too steep an angle, it tends to push back
toward the operator.
Working Conditions
Start and operate your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
English
Warning!
Inhalation of certain
dusts, especially organic
dusts such as mold or
pollen, can cause susceptible persons to have
an allergic or asthmatic
reaction. Substantial or repeated inhalation of dust and other airborne
contaminants, in particular those with a
smaller particle size, may cause respiratory or other illnesses. Control dust at
the source where possible. Use good
work practices, such as operating the
unit so that the wind or operating process directs any dust raised by the power
tool away from the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust ("particulate matter"). When the inhalation of
dust cannot be substantially controlled,
i.e., kept at or near the ambient (background) level, the operator and any
bystanders should wear a respirator
approved by NIOSH / MSHA for the type
of dust encountered.
Warning!
Static charges may build up when
cleaning synthetic floors – risk of electric
shock and accidents.
KB-MM, KW-MM

English
5m (16ft)
Warning!
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.
Warning!
Use the power tool at ground level only.
The risk of injury is increased if you use
MultiTools above ground level because
they are more exposed and the power
tool is more difficult to control.
Operating Instructions
Warning!
Do not operate your power tool using
the starting throttle lock, as you do not
have control of the engine speed.
In the event of an emergency, switch off
the engine immediately – move the slide
control / stop switch to 0 or STOP.
Warning!
The MultiTool continues to rotate for a
short period after the throttle trigger is
released (flywheel effect).
If the MultiTool or deflector becomes
clogged or stuck, always switch off the
engine and make sure the attachment
has stopped before cleaning. Dirt, grass,
weeds, etc. should be cleaned off the
attachment as necessary.
The rotating attachment may fling
foreign objects directly or by ricochet a
great distance. To reduce the risk of eye
and other injury ensure that bystanders
are at least 16 feet (5 m) away.
Bystanders should be encouraged to
wear eye protection. To reduce the risk
of damage to property, also maintain this
distance from such objects as vehicles
or windows.
Stop the engine immediately if you are
approached.
Warning!
Before you start work,
examine the area for
stones, glass, pieces of
metal, rubbish or other
solid objects. Such
objects could be hurled
by the sweeping tool and directly or indirectly strike the operator or bystanders.
Such objects may also damage the
sweeping tools.
Warning!
Never divert discharge of material
toward bystanders nor allow anyone
near the area of operation. Use care in
directing discharge to avoid damage to
surfaces, automobiles, and the like.
Warning!
During work, check the tightness and
the condition of the MultiTool at regular
intervals with the engine and attachment stopped. If the behavior of the
attachment changes during use, stop
the engine immediately and check the
attachment for cracks, wear and damage. Replace cracked or damaged
attachments immediately.
Warning!
The gearbox becomes hot during operation. To reduce the risk of burn injury,
do not touch the gear housing when it is
hot.
MAINTENANCE, REPAIR AND
STORING
Warning!
Always stop the engine and make sure
that the attachment is stopped before
doing any maintenance or repair work or
cleaning the power tool. Do not attempt
any maintenance or repair work not
described in your MultiEngine and
MultiTool instruction manuals. Have
such work performed at your STIHL
servicing dealer only.
Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
