Engineering improvements

STIHL’s philosophy is to continually
improve all of its products. As a result,
engineering changes and improvements
are made from time to time. If the
operating characteristics or the
appearance of your machine differ from
those described in this manual, please
contact your STIHL dealer for
assistance.

Therefore, we cannot be responsible for
changes, modifications or
improvements not covered in this
manual.

Warning!

Because a Combi Engine
equipped with a
PowerSweep CombiTool
is a high-speed power

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

owner's manuals and the
safety instructions of your CombiEngine
and CombiTool periodically. Careless or
improper use of any power tool 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!

Minors should never be allowed to use a
power tool. Bystanders, especially
children, and animals should not be
allowed in the area where a power tool is
in use!

Never let the PowerSweep run
unattended.

!Warning!

Do not lend or rent your power tool
without the owner's manuals. Be sure
that anyone using your power tool
understands the information contained
in these manuals.

Most of these safety precautions and
warnings apply to the use of all STIHL
PowerSweeps. Different models may
have different parts and controls. See
the appropriate section of your
CombiEngine and CombiTool owner's
manual for a description of the controls
and function of the parts of your power
tool 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 a
power tool when you are fatigued.

3KW-KM

English / USA

Be alert - if you get tired while operating
your power tool, 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 a
PowerSweep.

!Warning!

Prolonged use of a power tool (or other
machines) exposing the operator to
vibrations may produce whitefinger
disease (Raynaud's phenomenon) or
carpal tunnel syndrome. These con­ditions reduce the hand's ability to feel
and regulate temperature, produce
numbness and burning sensations and
may cause nerve and circulation
damage and tissue necrosis.

All factors which contribute to white­finger disease are not known, but cold
weather, smoking and diseases or
physical conditions that affect blood
vessels and blood transport, as well as
high vibration levels and long periods of
exposure to vibration are mentioned as
factors in the development of whitefinger
disease.

In order to reduce the risk of whitefinger
disease and carpal tunnel syndrome,
please note the following:

– Most STIHL power tools are

equipped with an anti-vibration
("AV") system designed to reduce
the transmission of vibrations
created by the engine to the
operator's hands. An AV system is
recommended for those persons
using power tools on a regular or
sustained basis.

– Wear gloves and keep your hands

warm.

– Keep the AV system well

maintained. A power tool with loose
components or with damaged or
worn AV buffers will tend to have
higher vibration levels.

– Maintain a firm grip at all times, but

do not squeeze the handles with
constant, excessive pressure, take
frequent breaks.

All the above mentioned precautions do
not guarantee that you will not sustain
whitefinger disease or carpal tunnel
syndrome. Therefore, continual and
regular users should monitor closely the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.

Proper Clothing

!Warning!

To reduce the risk of injury, the operator
should wear proper protective apparel.

!Warning!

Never operate a
PowerSweep unless
wearing goggles or
properly fitted safety
glasses with adequate top
and side protection

complying with your National Standard.

!Warning!

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.

Protect your hands with
gloves when handling the
power tool. Heavy-duty,
nonslip gloves improve
your grip and protect your
hands.

English / USA

Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement.

Avoid loose- fitting jackets,
scarfs, neckties, jewelry,
flared or cuffed pants,
unconfined longhair or
moving parts of the unit.

Wear long pants made of heavy material
to protect your legs. Do not wear shorts,
sandals or go bare foot. Secure hair so it
is above shoulder level.

Good footing is important
in PowerSweep work.
Wear sturdy boots with
nonslip soles.

Wear an approved safety
hard hat to reduce the risk
of injury to your head
when there is a danger of
head injuries.

THE POWER SWEEP
COMBITOOL

For illustrations and definitions of the
PowerSweep CombiTool parts see the
chapter on "Parts and Controls".

!Warning!

Never modify a CombiTool in any way.
Only CombiTools supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL power tool
models are authorized. Although certain
unauthorized CombiTools may be
useable for the STIHL power tool, their
use may, in fact, be extremely
dangerous.

THE USE OF THE POWER SWEEP
(COMBI ENGINE EQUIPPED WITH
POWER SWEEP COMBITOOL)

Transporting the PowerSweep

!Warning!

Always turn off the engine and make
sure the CombiTool has stopped before
putting a PowerSweep down. When
transporting your PowerSweep in a
vehicle, properly secure it to prevent
turnover, fuel spillage and damage to the
PowerSweep.

Preparation for the use of the
PowerSweep

Adjust carrying harness and hand grip to
suit your size before starting work. The
machine should be properly balanced as
specified in your owner's manual for
proper control and less fatique in
operation.

Always check your PowerSweep for
proper condition and operation before
starting, particularly the throttle trigger,
throttle trigger interlock (if applicable),
stop switch, sweeper drums, rubber
sleeve and harness.

The sweeper must be properly tightened
and in safe operating condition. Both
sweeper belts must be mounted. The
rubber sleeve on the end of the drive
tube must be in good condition. Do not
operate your PowerSweep with
damaged sweeper drums or rubber
sleeve. Inspect for loose parts (nuts,
screws, etc) and for worn or damaged
parts. Replace worn or damaged parts.

Fueling

Your STIHL PowerSweep uses an oil­gasoline mixture for fuel. For further
instructions see the safety precautions
and the chapter on "Fuel" of the owner's
manual of the CombiEngine.

!Warning!

Gasoline is an extremely
flammable fuel. If spilled
and ignited by a spark or
other ignition source, it
can cause fire and serious

burn injury or property
damage. Use extreme caution when
handling gasoline or fuel mix.

Do not smoke or bring any fire or flame
near the fuel or PowerSweep.

OPERATING INSTRUCTIONS

The PowerSweep is designed only for
sweeping sand, stones, gravel, leaves
and snow on grass, concrete or asphalt
and removing puddles of water from flat
surfaces. To reduce the risk of injury, do
not use your PowerSweep for any other
purpose.

Starting

!Warning!

Your PowerSweep is a one-person
machine.

If you start the engine in the "start
position" the sweeper belts will rotate
when the engine starts - this may set the
PowerSweep in motion back towards
the operator.

5m (16ft)

To reduce the risk of injury from thrown
objects or contact with the sweeper
belts, do not allow any other person
within a radius of 5 m (16 ft) of your own
position.

Stop the engine immediately if you are
approached. Start and operate your
PowerSweep without assistance. For
specific starting instructions, see the
appropriate section of the owner’s
manual of the CombiEngine. Place the
power tool on firm ground or other solid
surface in an open area. Maintain a
good balance and secure footing.

birth defects, or other reproductive
harm. If you are unfamiliar with the risks
associated with the particular dust or
fume at issue, consult your employer,
governmental agencies such as OSHA
and NIOSH and other sources on
hazardous materials. California and
some other authorities, for instance,
have published lists of substances
known to cause cancer, reproductive
toxicity, etc.

Control dust and fumes at the source
where possible. In this regard use good
work practices and follow the
recommendations of OSHA/NIOSH and
occupational and trade associations.
When the inhalation of toxic dust and
fumes cannot be eliminated, the
operator and any bystanders should
always wear a respirator approved by
NIOSH/MSHA for the type of dust and /
or fumes encountered.

!Warning!

Never attempt to operate any
PowerSweep with one hand. Loss of
control of the PowerSweep may result in
personal injury.

Special care must be taken in slippery
conditions (wet ground, snow).

Examine work area and

check for solid objects

(such as stones, pieces of

metal, etc.) which could

be thrown and cause

injury or damage the
sweeper flaps or other property (e.g.
parked vehicles, windows, etc.).

!Warning!

This PowerSweep is to be used at
ground level with the sweeper belts
parallel to the ground. Use of a
PowerSweep above ground level may
increase the risk of injury, since the
brooming attachment is more fully
exposed and the PowerSweep may be
more difficult to control.

Do not operate the PowerSweep using
the starting throttle lock as you do not
have control of the engine speed. See
section of your owner's manual on the
proper use of the slide control.

If the sweeper belts become clogged or
stuck, always turn off the engine and
make sure the sweeper belts have
stopped, before cleaning.

Important adjustments

!Warning!

To reduce the risk of personal injury from
loss of control or contact with the
running sweeper drums, do not use your
PowerSweep with incorrect idle
adjustment. At correct idle speed, the
sweeper drums should not move. For
directions on how to adjust idle speed,
see the appropriate section of the
owner's manual of the CombiEngine.

If you cannot set the correct idle speed,
have your STIHL dealer check your
PowerSweep and make proper
adjustments and repairs.
