Safety Precautions and Working Techniques
english / USA
Warning!
Because a PowerSweep
is a 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 manual and the
safety instructions periodically. Careless
or improper use of any PowerSweep
may cause serious or fatal injury. Have
your STIHL dealer show you how to
operate your PowerSweep. Observe all
applicable local safety regulations,
standards and ordinances.
!Warning!
Minors should never be allowed to use a
PowerSweep. Bystanders, especially
children, and animals should not be
allowed in the area where a
PowerSweep is in use.
Never let the PowerSweep run
unattended.
!Warning!
Do not lend or rent your PowerSweep
without the owner's manual. Be sure that
anyone using your PowerSweep
understands the information contained
in this manual.
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 owner's
manual for a description of the controls
and function of the parts of your model
PowerSweep.
Safe use of a PowerSweep involves
1. the operator
2. the PowerSweep
3. the use of the PowerSweep .
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
PowerSweep when you are fatigued.
Be alert - if you get tired while operating
your PowerSweep, take a break.
Tiredness may result in loss of control.
Working with any PowerSweep 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 PowerSweep (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.
3KW 85
Page 5
english / USA
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 PowerSweep 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.
persons with pacemaker should consult
their physician and the pacemaker
manufacturer before operating this tool.
Proper Clothing
!Warning!
To reduce the risk of injury, the operator
should wear proper protective apparel.
Never operate a
PowerSweep unless
wearing goggles or
properly fitted safety
glasses with adequate top
and side protection
complying with your
National Standard.
PowerSweep 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
PowerSweep. Heavyduty, nonslip gloves
improve your grip and
protect your hands.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Avoid loosefitting 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.
!Warning!
The ignition system of the STIHL unit
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce the risk of serious or fatal injury,

THE POWER SWEEP
For illustrations and definitions of the
PowerSweep parts see the chapter on
"Parts and Controls"
!Warning!
Never modify a PowerSweep in any
way. Only attachments supplied by
STIHL or expressly approved by STIHL
for use with the specific STIHL
PowerSweep models are authorized.
Although certain unauthorized
attachments may be useable for the
STIHL Power Sweep, their use may, in
fact, be extremely dangerous.
THE USE OF THE POWER SWEEP
Transporting the PowerSweep
!Warning!
Always turn off the engine and make
sure the attachment 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 throttle trigger must move freely and
always spring back to the idle position.
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 (see the chapter on "Fuel" of your owner's manual).
!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.
Fueling Instructions
Fuel your PowerSweep in wellventilated areas, outdoors only.
!Warning!
Gasoline vapor pressure may build up
inside the gas tank of a two cycle engine
depending on the fuel used, the weather
conditions, and the venting system of
the tank. In order to reduce the risk of
burns and other personal injury from
escaping gas vapor and fumes, remove
the fuel filler cap on your PowerSweep
carefully so as to allow any pressure
build-up in the tank to release slowly.
5KW 85
Page 7
english / USA
Never remove fuel filler cap while engine
is running. Select bare ground for fueling
and move at least 10 feet (3 m) from the
fueling spot before starting the engine.
Wipe off any spilled fuel before starting
your PowerSweep and check for
leakage.
!Warning!
Check for fuel leakage while refueling
and during operation. If fuel or oil
leakage is found, do not start or run the
engine until leak is fixed and spilled fuel
has been wiped away. If this happens,
change your clothing immediately.
!Warning!
Unit vibrations can cause
an improperly tightened
fuel cap to loosen or come
off and spill quantities of
fuel. In order to reduce
risk of fuel spillage and
fire, tighten fuel cap by hand with as
much force as possible.
OPERATING INSTRUCTIONS
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 (15 f) 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 your manual.
Place the PowerSweep on firm ground
or other solid surface in an open area.
Maintain a good balance and secure
footing.
!Warning!
When you pull the starter grip, don't
wrap the starter rope around your hand.
Do not allow the grip to snap back, but
guide the starter rope to rewind it
properly. Failure to follow this procedure
may result in injury to hand or fingers
and may damage the starter
mechanism.
With the engine running but at idle,
attach the PowerSweep to the spring
hook of your harness (see appropriate
chapter of this manual).
Working Conditions
Operate and start your PowerSweep
only outdoors in a well ventilated area.

ventilated locations.
monoxide) may be
!Warning!
Use of this product can generate dust
and fumes containing chemicals known
to cause respiratory disease, cancer,
223BA002 KN
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!
The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
hot for a while after stopping the engine.
To reduce risk of burns do not touch the
muffler and other parts while they are
hot.
Operate the PowerSweep under good
visibility and daylight conditions only.
Work carefully.
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.

english / USA
Always hold the PowerSweep firmly with
both hands. Wrap your fingers tightly
around the handles, keeping the
handles cradled between your thumb
and fore-finger. Keep your hands in this
position, to have your PowerSweep
under control at all times. Make sure
your PowerSweep handles and grip are
in good condition and free of moisture,
pitch, oil or grease.
!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.).
002BA054 KN
!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 your
owner's manual.
If you cannot set the correct idle speed,
have your STIHL dealer check your
PowerSweep and make proper
adjustments and repairs.
MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However if you claim
warranty for a component which has
not been serviced or maintained
properly or if nonapproved
replacement parts were used, STIHL
may deny warranty.
8
KW 85
Page 10
english / USA
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Follow the maintenance and repair
instructions in the appropriate section of
your owner's manual. Please refer to the
maintenance chart at the last pages of
this manual.
!Warning!
Always stop the engine and make sure
that the sweeper belts have stopped
before doing any maintenance or repair
work or cleaning the PowerSweep. Do
not attempt any maintenance or repair
work not described in your owner's
manual. Have such work performed at
your STIHL dealer shop only.
!Warning!
Check condition of sweeper belts at
regular intervals. Loose particles or
pieces of the belts could be thrown and
injure the operator or bystanders. To
reduce risk of injury from broken parts
replace damaged sweeper belts
immediately and always in pairs. Do not
reuse or attempt to repair damaged or
worn sweeper belts.
!Warning!
To reduce the risk of fire and burn
injuries, check fuel filler cap for leaks at
regular intervals. Use the specified
spark plug and make sure it and the
ignition lead are always in good
condition.
!Warning!
Never test the ignition system with
ignition wire boot removed from spark
plug or with unseated spark plug, since
uncontained sparking may cause a fire.
!Warning!
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug boot of the
proper size. (Note: If boot has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug boot and ignition wire
connector in the boot may create arcing
that could ignite combustible fumes and
cause a fire. Keep spark plug clean, and
make sure ignition lead is in good
condition.
!Warning!
Do not operate your PowerSweep if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or burn will
result. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire (e.g. in the USA, Canada and
Australia), never operate your
PowerSweep if the screen is missing or
damaged. Do not modify or remove any
part of the muffler or spark arresting
screen. Remember that the risk of forest
fires is greater in hot or dry weather.
Tighten all nuts, bolts and screws,
except the carburetor adjustment
screws, after each use.
Additionally, the daily maintenance
schedule for your PowerSweep set forth
in your STIHL Owner's Manual should
be strictly followed.
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of this manual.
Store PowerSweep in a dry, high or
locked location out of reach of children.
Before storing for longer than a few
days, always empty the fuel tank.

This engine is certified to operate on
unleaded gasoline and with the mix ratio
50:1.
Your two-stroke engine requires a
mixture of brand-name gasoline and
quality two-stroke engine oil with the
classification TC.
Use regular branded unleaded gasoline
with a minimum octane rating of 89
RON. If the octane rating of the regular
grade gasoline in your area is lower use
premium unleaded fuel.
Fuel with a lower octane rating may
result in preignition (causing "pinging")
which is accompanied by an increase in
engine temperature. This, in turn,
increases the risk of the piston seizure
223BA010 KN
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines etc.), but magnesium castings as
well. This could cause running problems
or even damage the engine. For this
reason it is essential that you use only
name branded fuels!
Use only STIHL two-stroke engine oil or
equivalent branded two-stroke aircooled engine oils with the classification
TC for mixing.
We recommend STIHL 50:1 two-stroke
engine oil since it is specially formulated
for use in STIHL engines.
Do not use BIA or TCW (two-stroke
water cooled) mix oils!
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapour.
The canister should be kept tightly
closed in order to avoid any moisture
getting into the mixture.
The fuel tank and the canister in which
fuel mix is stored should be cleaned
from time to time.
Fuel mix ages
Only mix sufficient fuel for a few days
work, not to exceed 3 months of storage.
Store in approved safety fuel-canisters
only. When mixing, pour oil into the
canister first, and then add gasoline.

Fueling
Before fueling, clean the filler cap and
the area around it to ensure that no dirt
falls into the tank.
Always thoroughly shake the mixture in
the canister before fueling your
machine.
In order to reduce the risk of burns
or other personal injury from
escaping gas vapor and fumes,
remove the fuel filler cap carefully
so as to allow any pressure build-up
in the tank to release slowly.
After fueling, tighten fuel cap as
securely as possible by hand.

Operating Instructions Using the PowerSweep
During break-in period
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessary high loads during the
break-in period.
As all moving parts have to bed in during
the break-in period, the frictional
resistances in the engine are greater
during this period. The engine develops
its maximum power after about 5 to 15
tank fillings.
During operation
After a long period of full-throttle
operation, allow engine to run for a while
at idle speed so that the heat in the
engine can be dissipated by flow of
cooling air. This protects enginemounted components (ignition,
carburetor) from thermal overload.
After finishing work
Wait for engine to cool down. Drain the
fuel tank . Store the machine in a dry
place. Check tightness of nuts and
screws (not adjusting screws) at regular
intervals and retighten as necessary.
Use the PowerSweep for sweeping
sand, stones, gravel, leaves and snow
on grass, concrete or asphalt and
removing standing water from solid
surfaces.
: To reduce risk of accidents or injury,
remove all obstacles and objects
from the work area.
: If the work area is very dry, spray it
with water if necessary to reduce
the amount of dust created.
: Push the PowerSweep steadily at
walking pace.
: Always keep the drive tube at a
shallow angle (see illustration).
!!!! The steeper the angle between the
drive tube and the ground, the more
difficult it is to control the
PowerSweep.
: Do not push the PowerSweep into
the ground.

counterclockwise (richer) no further
than stop until there is no noticeable
increase in engine speed.
It is possible that maximum engine
speed may be reached with the
standard setting in each case.
Adjusting Idle Speed
It is usually necessary to change the
setting of the idle speed screw (LA)
after every correction to the low speed
screw (L).
: Warm up engine.
Engine stops while idling
: Turn idle speed screw (LA) slowly
clockwise until the engine runs
smoothly – sweeper drum must not
rotate.

idling
: Turn idle speed screw (LA) slowly
counterclockwise until sweeper
drum stops rotating and then turn
the screw about another
1
/2 to 1 turn
in the same direction.
Erratic idling behavior, engine stops
even though setting of LA screw is
correct, poor acceleration
Idle setting too lean:
: Turn low speed screw (L)
counterclockwise (about 1/4 turn)
until the engine runs and
accelerates smoothly.

Checking the Spark Plug
Wrong fuel mix (too much engine oil in
the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition of
the spark plug. These factors cause
deposits to form on the insulator nose
which may result in trouble in operation.
If engine is down on power, difficult
to start or runs poorly at idling speed,
first check the spark plug.
: Remove spark plug as discribed
in chapter “Starting“
: Clean dirty spark plug.
: Check electrode gap (A) -
it should be 0.5mm/0.02" readjust if necessary.
: Use only resistor type spark plugs
of the approved range.
Rectify problems which have caused
fouling of spark plug:
: Too much oil in fuel mix.
000BA002 KN
: Dirty air filter.
: Unfavorable running conditions.
Fit a new spark plug after approx. 100
operating hours
or earlier if the electrodes are badly
eroded.
1
000BA036 TR
To reduce the risk of fire and burn
injury, use only spark plugs
authorized by STIHL. Always press
spark plug boot (2) snugly onto
spark plug boot (1) of the proper
size. (Note: If boot has detachable
SAE adapter nut, it must be
attached.) A loose connection
between spark plug boot and
ignition wire connector in the boot
may create arcing that could ignite
combustible fumes and cause a fire.

Engine Running Behavior Storing the Machine
If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor properly
adjusted, the cause may be in the
muffler.
Have the muffler checked for
contamination (coking) by a STIHL
dealer.
For periods of about 3 months or
longer
: Drain and clean the fuel tank in a
well ventilated area.
: Run engine until carburetor is dry -
this helps prevent carburetor
diaphragms sticking together.
: Remove and clean the sweeper
drums, inspect belts for damage or
wear.
: Thoroughly clean the machine - pay
special attention to the cylinder fins
and air filter.
: Store the machine in a dry, high or

"repair or replace as necessary" will be
warranted for the warranty period.
Any warranted part which is scheduled
for replacement as required maintenance will be warranted for the period of
time up to the first scheduled replacement point for that part.
Diagnosis
You, as the owner, shall not be charged
for diagnostic labor which leads to the
determination that a warranted part is
defective. However, if you claim
warranty for a component and the
machine is tested as non-defective,
STIHL Incorporated will charge you for
the cost of the emission test.
Mechanical diagnostic work will be
performed at an authorized STIHL
servicing dealer. Emission test may be
performed either at STIHL Incorporated
or at any independent test laboratory.
Warranty Work
STIHL Incorporated shall remedy warranty defects at any authorized STIHL
servicing dealer or warranty station. Any
such work shall be free of charge to the
owner if it is determined that a warranted
part is defective. Any manufacturerapproved or equivalent replacement part
may be used for any warranty
maintenance or repairs on emissionrelated parts and must be provided
without charge to the owner. STIHL
Incorporated is liable for damages to
other engine components caused by the
failure of a warranted part still under
warranty.
