• Safe use involves the operator, the PowerSweep, and its proper application.

Operator's Physical Condition:

• Be in good physical and mental health.
• Do not operate under the influence of drugs, alcohol, or anything that impairs vision, dexterity, or judgment.
• Do not operate when fatigued. Take breaks if you become tired, as tiredness can lead to loss of control.
• If you have any condition that could be aggravated by strenuous work, consult your doctor before operating.

Vibration and Health Risks:

• Prolonged exposure to vibrations can cause whitefinger disease (Raynaud's phenomenon) or carpal tunnel syndrome, affecting hand sensation, temperature regulation, and potentially causing nerve damage.
• Factors contributing to these conditions include cold weather, smoking, poor circulation, high vibration levels, and long exposure times.

Reducing Vibration Exposure:

• Most STIHL power tools are equipped with an anti-vibration (AV) system. Ensure the AV system is well-maintained; loose or worn AV buffers increase vibration levels.
• Wear gloves and keep your hands warm.
• Maintain a firm grip but avoid excessive pressure; take frequent breaks.
• Regular users should monitor their hands and fingers for symptoms and seek medical advice if symptoms appear.

Pacemaker Warning:

• The STIHL unit's ignition system produces a low-intensity electromagnetic field that may interfere with pacemakers. Consult your physician and the pacemaker manufacturer before operating.

Proper Clothing and Footwear:

• Wear sturdy, snug-fitting clothing that allows freedom of movement. Avoid loose items like scarves or jewelry.
• Wear long pants made of heavy material. Do not wear shorts, sandals, or go barefoot. Secure long hair.
• Ensure good footing with sturdy boots that have nonslip soles.
• Wear an approved safety hard hat if there is a risk of head injury.

The Power Sweep

Refer to the "Parts and Controls" chapter for illustrations and definitions of PowerSweep components.

Modifications:

• Never modify the PowerSweep. Only use attachments supplied or expressly approved by STIHL for your specific model. Unauthorized attachments can be extremely dangerous.

The Use of the Power Sweep

Transporting the PowerSweep:

• Always turn off the engine and ensure the attachment has stopped before setting the PowerSweep down.
• When transporting in a vehicle, secure it properly to prevent turnover, fuel spillage, and damage.

Preparation for Use:

• Adjust the carrying harness and hand grip to suit your size for proper balance and control.
• Before starting, check your PowerSweep for proper condition and operation, including the throttle trigger, stop switch, sweeper drums, rubber sleeve, and harness.
• The throttle trigger must move freely and spring back to idle.
• Ensure sweeper drums and belts are properly tightened and in safe operating condition.
• Inspect for loose or worn parts and replace as necessary.

Fueling:

• Your STIHL PowerSweep uses an oil-gasoline mixture (50:1 ratio). Refer to the "Fuel" chapter for details.
• ⚠ Warning: Gasoline is highly flammable. Use extreme caution when handling. Do not smoke or bring flames near fuel.

Fueling Instructions:

• Fuel outdoors in a well-ventilated area.
• ⚠ Warning: Gasoline vapor pressure can build up. Remove the fuel filler cap slowly to release any pressure build-up.
• After fueling, tighten the fuel cap securely by hand.
• Change the fuel pick-up body every year.
• Before long-term storage, drain and clean the fuel tank, and run the engine until the carburetor is dry.

Attaching Machine to Harness:

• Attach the spring hook (1) to the clamp (2).

Working Conditions

Operate and start your PowerSweep only outdoors in a well-ventilated area.

Safety Zone:

• To reduce the risk of injury from thrown objects or contact with sweeper belts, keep all other persons at least 5 meters (16 ft) away from your position.
• Stop the engine immediately if someone approaches.
• Start and operate the PowerSweep without assistance.

Operation Area:

• Place the PowerSweep on firm ground in an open area. Maintain good balance and secure footing.

Starting Procedure:

• ⚠ Warning: When pulling the starter grip, do not wrap the rope around your hand. Guide the starter rope to rewind properly; do not let it snap back. Failure to do so may result in hand/finger injury or damage to the starter mechanism.
• With the engine running at idle, attach the PowerSweep to the spring hook of your harness.

Reversing the PowerSweep:

• ⚠ Warning: Reversing the PowerSweep will cause debris to be thrown back towards the operator. Use lower throttle settings and be aware that thrown debris may affect your footing.

Operating Instructions

Starting:

• ⚠ Warning: The PowerSweep is a one-person machine. If you start the engine in the "start position", the sweeper belts may rotate when the engine starts, potentially moving the PowerSweep towards the operator.
• Loosen the screw (3) that secures the clamp.
• Slide the clamp up or down the drive tube so that the sweeper belts touch the ground. Tighten the screw firmly.

Controls:

• The controls include the throttle trigger interlock (1), throttle trigger (2), and slide control (3).
• The slide control has positions for: START (4), I - normal run position (5), and ∅ - stop (6). To stop the engine, move the slide control to the stop position (7).

Starting Procedure:

• Hold down the throttle trigger interlock and squeeze the throttle trigger.
• While holding both levers, move the slide control to the START position and hold it there.
• Release the throttle trigger, slide control, and throttle trigger interlock in that order. This sets the starting throttle position.

Choke Lever and Fuel Pump:

• Set the choke lever (8):
• For cold start, set to ≠ (choke on).
• For warm start, set to ≡ (choke off/run), even if the engine has been running but is still cold.
• Press the fuel pump bulb (9) at least five times.

Cranking the Engine:

• Hold the unit securely with a firm footing. Hold the unit with your left hand and press it down firmly.
• ⚠ Warning: If you crank the engine in the "Start" position, the sweeper belts may rotate when the engine starts, potentially moving the PowerSweep.
• Do not stand or kneel on the drive tube.
• Pull the starter grip slowly with your right hand until you feel it engage, then give it a brisk, strong pull. Do not pull the starter rope all the way out, as it might break.
• Do not let the starter grip snap back; guide it slowly back into the housing so the rope rewinds properly.
• Continue cranking until the engine runs.
• When the engine begins to fire, move the choke lever to ≡ and continue cranking.

After the Engine Runs:

• Blip the throttle trigger; the slide control should move to the run position (I), and the engine should settle to idle speed.
• Ensure the carburetor is correctly adjusted; the sweeper drums must not rotate when the engine is idling.
• Your machine is now ready for operation.

To Shut Down the Engine:

• Move the slide control in the direction of ∅ (stop).

Operation at Very Low Outside Temperatures:

• Allow the engine to warm up.
• As soon as the engine runs, blip the throttle trigger to disengage the starting throttle position. The slide control should move to the run position (I), and the engine should return to idling speed.
• Open the throttle slightly and allow the engine to warm up for a brief period.

If the Engine Does Not Start:

• If the choke lever was not moved to ≡ quickly enough after the engine began to fire, the combustion chamber may be flooded. Move the choke lever to ≠, set the slide control, interlock lever, and throttle trigger to the starting throttle position. Crank the engine briskly (10-20 pulls may be necessary).
• If the engine still does not start: Move the slide control to the stop position (∅). Pull off the spark plug boot (10). Unscrew and dry the spark plug. Open the throttle wide. Crank the engine several times with the starter to clear the combustion chamber. Refit the spark plug and connect the spark plug boot firmly. Move the slide control to START. Set the choke lever to ≠, even if the engine is cold. Now start the engine.

Fuel Tank Run Until Dry and Then Refueled:

• Press the fuel pump bulb at least five times, even if it appears filled with fuel.
• Now start the engine.

Using the PowerSweep

During Break-in Period:

• A new machine should not be run at high revolutions (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads. Frictional resistances are greater during this period, and maximum power is developed after about 5 to 15 tank fillings.

During Operation:

• After extended periods of full-throttle operation, allow the engine to run at idle speed for a while to dissipate heat through cooling air. This protects engine-mounted components from thermal overload.

After Finishing Work:

• Wait for the engine to cool down. Drain the fuel tank. Store the machine in a dry place.
• Regularly check the tightness of nuts and screws (excluding adjustment screws) and retighten as necessary.

General Use:

• Use the PowerSweep for sweeping sand, stones, gravel, leaves, and snow on grass, concrete, or asphalt, and for removing standing water from solid surfaces.
• To reduce the 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 to reduce dust creation.
• Push the PowerSweep steadily at a walking pace.
• Always keep the drive tube at a shallow angle (see illustration). A steeper angle makes the PowerSweep more difficult to control.
• Do not push the PowerSweep into the ground.

Sweeping Narrow Areas:

• Guide the sweeper drum at right angles to the direction of travel (1). Sweepings are thrown forwards. The PowerSweep pushes back toward the operator.

Sweeping Wide Areas:

• Guide the sweeper drum at an angle to the direction of travel (1). Sweepings are thrown forwards to one side. The PowerSweep pushes back toward the operator.

Sweeping Corners:

• Turn the PowerSweep over. Sweepings are thrown back toward the operator. For this reason, run the PowerSweep at a low throttle setting only. The PowerSweep pulls the operator forward, and debris thrown back may affect footing.

Disconnecting Machine from Harness:

• Press down the bar (1) on the spring hook (2).
• Pull the clamp (3) out of the spring hook.

Cleaning the Air Filter

Dirty air filters reduce engine power, increase fuel consumption, and make starting more difficult.

If there is a noticeable loss of engine power:

• Move the choke lever to ≠ (choke on).
• Press the tab (1).
• Ease the filter cover (2) over the tab and remove it.
• Clean away loose dirt from around the filter.
• Remove the foam and felt filter elements.
• Wash the foam element in a clean, non-flammable cleaning solution (e.g., warm soapy water) and then dry it.
• For the felt element, as a temporary measure, you can knock it out on the palm of your hand or blow it out with compressed air. Do not wash the felt element.
• Replace damaged parts.
• Install the foam element (3) in the filter cover (2).
• Place the felt element (4) (with lettering facing inward) in the filter housing (5).
• Fit the filter cover so that it snaps into position.

Motor Management

Exhaust emissions are controlled by the design of the fundamental engine parameters and components, such as carburation, ignition, timing, and valve or port timing, without the addition of any major hardware.

Adjusting the Carburetor

The carburetor is set at the factory to provide an optimum fuel-air mixture under all operating conditions.

Adjusting with Idle Speed Screw (LD):

• Standard Setting:
• Mount the sweeper drum assemblies.
• Check the spark arresting screen and clean or replace it as necessary.
• Check the air filter and replace it as necessary.
• Carefully screw the idle speed screw (LD) down onto its seat (counterclockwise, left-hand thread). Then open it two full turns clockwise for the standard setting.

Adjusting with Idle Speed Screw LA:

• Standard Setting:
• Mount the sweeper drum assembly and ensure it is in good condition.
• Check the spark arresting screen and clean or replace it as necessary.
• Check the air filter and replace it as necessary.
• Turn the high speed screw (H) counterclockwise (max. 3/4 turn) as far as stop.
• Carefully screw the low speed screw (L) down onto its seat. Then open it one turn counterclockwise.
• Start the engine and allow it to warm up as necessary.
• Adjust the idle speed with the idle speed screw (LA) so that the sweeper drums do not rotate.
• Fine Tuning: A slight correction of the high speed screw (H) may be necessary if engine power is unsatisfactory when working at high altitudes or at sea level.

Adjusting Idle Speed:

• Carry out the standard setting. Start the engine and allow it to warm up.
• Engine stops while idling: Turn the idle speed screw (LD) slowly clockwise until the engine runs smoothly; the sweeper drums must not rotate.
• Sweeper drums rotate when engine is idling: Turn the idle speed screw (LD) counterclockwise until the sweeper drums stop rotating, then turn the screw about another 1/2 to 1 turn in the same direction.
• Erratic idling behavior, poor acceleration: Turn the idle speed screw (LD) slowly counterclockwise, no more than one half turn.

Adjusting Carburetor for High Altitudes and Sea Level:

• Carry out the standard setting. Run the PowerSweep for about 3 to 5 minutes to warm up the engine.
• Rule of thumb: Turn the high speed screw (H) about 1 to 2 notches for every 1000 meter change in altitude. Open the throttle wide.
• At high altitudes: Turn the high speed screw (H) clockwise (leaner) no further than stop until there is no noticeable increase in engine speed.
• At sea level: Turn the high speed screw (H) 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 (LA):

• 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 the engine.
• Engine stops while idling: Turn idle speed screw (LA) slowly clockwise until the engine runs smoothly – the sweeper drum must not rotate.
• Sweeper drum rotates when engine is 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.
• Idle setting too rich: Turn low speed screw (L) clockwise (about 1/4 turn) until the engine runs and accelerates smoothly.

Checking the Spark Plug

Wrong fuel mix (too much engine oil), a dirty air filter, and unfavorable running conditions can affect the spark plug, causing deposits on the insulator nose which may result in operational trouble.

If the engine is down on power, difficult to start, or runs poorly at idling speed, first check the spark plug.

• Remove the spark plug as described in the "Starting" chapter.
• Clean the dirty spark plug.
• Check the 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.
• Dirty air filter.
• Unfavorable running conditions.
• Fit a new spark plug after approximately 100 operating hours, or earlier if the electrodes are badly eroded.

⚠ Warning: To reduce the risk of fire and burn injury, use only spark plugs authorized by STIHL. Always press the spark plug boot (2) snugly onto the spark plug boot (1) of the proper size. (Note: If the boot has a detachable SAE adapter nut, it must be attached.) A loose connection between the spark plug boot and ignition wire connector can create arcing that could ignite combustible fumes and cause a fire.

Removing the Gearbox

• Straighten the ends of the cotter pin and remove the cotter pin.
• Pull the sweeper drum off the shaft.
• Examine the gear housing for signs of oil. If leaks are found, have your STIHL dealer check the gearbox.
• Repeat the above procedure on the other side.
• Release the clamp screw (1).
• Pull the gearbox (2) off the drive tube (3) – turn the gearbox back and forth at the same time to ease removal.

Replacing the Rubber Sleeve

The rubber sleeve protects the drive tube from wear caused by contact with the sweeper belts. It is fitted on either the drive tube or the gearbox. A worn sleeve must be replaced as follows:

• Remove the gearbox (refer to "Removing the Gearbox").
• Remove the worn sleeve from the drive tube. Cut it open with a knife if necessary.
• Pull the worn sleeve off the gearbox.
• Push the new sleeve onto the gearbox.
• Install the gearbox (refer to "Installing the Gearbox").

Replacing Sweeper Drum

• Straighten the ends of the cotter pin and remove the cotter pin.
• Pull the sweeper drum off the axle. Repeat the procedure on the other side.
• Examine gear housing for signs of oil. If leaks are found, have your STIHL dealer check the gearbox.
• Fit a new cotter pin (7) in the end of axle (2) and bend over the ends (8) of the cotter pin as shown. Repeat the procedure on the other side.
• Always replace sweeper drum assemblies in pairs.
• Push the new sweeper drum (6) onto the axle (2).

Replacing the Starter Rope and Rewind Spring

• Take out the screws (1).
• Remove the cable lug.
• Lift the starter cover (2) away from the tank (3) and pull it out from under the shroud (4).
• Take out the screw (5).
• Remove the rope rotor very carefully, as the rewind spring is seated within it and may pop out and uncoil if care is not taken.
• Use a screwdriver to ease the cap (6) out of the starter grip.
• Remove remaining rope from the rotor and grip, ensuring the ElastoStart sleeve is not pushed out of the grip.
• Tie a simple overhand knot in the end of the new starter rope and thread the rope through the top of the grip and the rope bush (7).
• Refit the cap in the grip.
• Pull the rope through the rotor and secure it with a simple overhand knot.
• Coat the rope rotor bearing bore with non-resinous oil.
• Slide the rotor onto the starter post, turn it back and forth until the rewind spring anchor loop (8) engages.
• Insert the screw and tighten down securely.
• Proceed to "Tensioning the rewind spring".

Replacing a Broken Rewind Spring

• Lubricate the new spring with a few drops of non-resinous oil; do not open the wire retainer.
• Remove the rope rotor.
• Remove parts of the old spring.
• Fit the new spring, positioning the outer spring loop in the recess. The wire retainer slips off in this process.
• If the spring has popped out: Refit it in the counterclockwise direction, starting outside and working inward.
• Install the rope rotor.
• Check dimension "a" on the inner spring loop and bend it to size if necessary.
• Proceed to "Tensioning the rewind spring".

Tensioning the Rewind Spring:

• Make a loop in the unwound starter rope and use it to turn the rope rotor six full revolutions counterclockwise.
• Hold the rotor steady, straighten the twisted rope, and release the rotor. Let the rope go slowly so that it winds onto the rotor.

Starter Grip and Spring Tension

The starter grip must be firmly seated in the rope guide bush. If the grip droops to one side, add one more turn on the rope rotor to increase spring tension. When the starter rope is fully extended, it must be possible to rotate the rotor another half turn. If this is not the case, the spring is overtensioned and could break; take one turn of rope off the rotor.

Fitting the Starter Cover:

• To fit the starter cover, push the upper mounting boss under the shroud, line up the tank, and push the lower part of the cover onto the tank.
• Insert and tighten down the housing screws.
• Secure the cable lug in position.

Spark Arresting Screen in Muffler:

• If the engine is low on power, check the spark arresting screen in the muffler.
• Lift the spark arresting screen and pull it out sideways.
• Clean the spark arresting screen if necessary.
• If the screen is damaged or coked up, fit a new one.
• Refit the spark arresting screen.

Engine Running Behavior

If engine running behavior is unsatisfactory, even though the air filter is clean and the carburetor is properly adjusted, the cause may be in the muffler. Have the muffler checked for contamination (coking) by a STIHL dealer.

Storing the Machine

For periods of about 3 months or longer:

• Drain and clean the fuel tank in a well-ventilated area.
• Run the engine until the carburetor is dry; this helps prevent carburetor diaphragms from sticking together.
• Remove and clean the sweeper drums; inspect belts for damage or wear.
• Thoroughly clean the machine, paying special attention to the cylinder fins and air filter.
• Store the machine in a dry, high, or locked location – out of the reach of children and other unauthorized persons.
