Basic PowerBoss® safety
PowerBoss® sweepers should never be operated unless:
- The operator is trained and authorized to operate the equipment and,
- The equipment is free of malfunctions. Malfunctioning equipment should be removed from service.
Keep cigarettes, matches and all other flame sources away from the sweeper. Gasoline, LP gas and diesel fuel are highly flammable. Lead acid batteries are equally dangerous due to the highly explosive hydrogen gas they emit.
Before starting the engine, make sure that:
- You are securely seated in the operator’s seat.
- The parking brake is locked.
- The directional control pedal is in neutral.
- The throttle is in idle.
- Hydraulic controls are in the OFF position.
During operation:
- Keep your hands and body clear of moving parts, especially when the hopper or lift arms are partially or fully raised.
- Make sure others in the area stay clear of the equipment and moving parts.
- Never attempt to dump debris from a dock or mezzanine. Dump from ground level only.
When leaving the sweeper unattended:
- Place the controls in the OFF position.
- Set the parking brake.
- Shut off the engine.
When servicing or repairing the fuel system:
- Work in a properly ventilated area, do not smoke or allow an open flame near the fuel system.
- Never bypass safety components unless you are testing them.
- Never bypass the fuel filter lock, except when testing them (and always reconnect them after testing).
- Wear gloves to disconnect the tank coupling.
During cleaning and maintenance:
- Always stop the engine and set the parking brake before servicing.
- Never use detergents or cleansers that are flammable or combustible.
- Never inflate a pneumatic tire without using a safety cage.
- Do not attempt any impeller adjustment unless you have shut off the engine. Never place your hands near the intake hoses or inlet when the engine is running.
- Always engage the safety arm before servicing the hopper. Do not rely on the hydraulic cylinder to keep the hopper raised.
- Never test for hydraulic hose leaks using your hand or any other part of your body. High pressure leaks can be very dangerous and should only be checked using a piece or paper.
Do not operate an LP powered sweeper when any component in the fuel system is malfunctioning or leaking.
Replace any defective safety components before operating the sweeper.
Do not drive with the hopper in the raised position except the few feet necessary to position the hopper over the dumpster or receptacle. Driving with the hopper raised reduces visibility and creates conditions for striking over-head objects, throwing the machine off-balance and other hazards.
Travel slowly on grades.
Place a block or chock behind the wheels when parking on inclines.
Use special care when traveling on wet surfaces.
Observe all proper procedures for operation and maintenance of the sweeper, as outlined in this manual.
Remain alert at all times to people and equipment in and around your area of operation.
Do not operate the #2 RTR lever before the #1 RTR lever light illuminates.
Never push or tow a machine faster than 1 mph (1.6 km/hr).
Engage tow valve before towing or pushing.

- Push Lever 2 forward to the RETURN position until the hopper rotates back and stops.
- Push Lever 1 forward to the LOWER position until the hopper returns to the normal operating position.
- Move the throttle to the RUN position and resume sweeping.
Transporting the machine
Using a trailer or transport vehicle
- Position the machine on the transport vehicle or trailer and apply the parking brake.
- Tie the machine down using the tie down holes in the frame forward of the front wheels and the hook bracket in the rear center of the frame.
NOTE: Attach the tie downs to the frame only.
Pushing the machine
Push the machine from the front or rear using the bumpers only.
Do not tow or push the machine a distance of more than 0.5 mi (0.8 km) or faster than 1 mph (1.6 km/hr). Exceeding these restrictions may cause damage to the hydraulic system. If towing will exceed the above restrictions, the rear wheel must be raised or supported by a dolly.
Options
Neutral start sensor
The Neutral Start Sensor safety option will not allow the engine to be started, if the Directional Control Pedal is pressed in the forward or backward position. The Pedal must remain in the neutral position to start the engine.
Operator seat sensor
The Operator Seat Sensor safety option senses when the operator of the vehicle is sitting in the driver seat. This sensor will automatically turn off the running engine, if the operator leaves the seat for longer than 3 seconds.
Second hand operation pushbutton
The second hand operation pushbutton is for operator safety when lowering the debris hopper. The operator must hold the yellow pushbutton on the side of the steering box. Once the pushbutton is held the operator may lower the hopper using the manual lever of the main spool valve. If the pushbutton is released at any point the hopper will stop lowering. The hopper may be lifted without holding the pushbutton as this is for lowering only.
Raise hopper - main broom shut off
The Main Broom Shut Off (when hopper is raised) is a safety option that automatically shuts the main broom off, once the hopper is raised.
Automatic diesel shutoff switch
Only on the Diesel machines, this switch is an automatic diesel shutdown that occurs if the oil pressure is too low, below 5 psi (34 kPa), and/or the water temperature is too high, above 200°F (93.3°C). To start the engine, press and hold the switch while turning the ignition switch. This will action will reset and clear the error code. Auto shutdown will continue if the oil pressure remains low or the water temperature is to high.
Low LP indicator
The low LP indicator is an option on machines powered by LP gas. The light is connected to a pressure valve mounted in the LP lines. When the pressure gets low in the LP tank (approximately 40 PSI) the indicator light will illuminate red. The indicator light is located on the operator dash area. When the light comes on the machine has approximately five minutes of running time left. The operator should go to the refueling station as soon as it is safely possible.
Parking brake bypass switch
The parking brake bypass switch allows the machine to keep running when the operator gets off of a machine equipped with a seat switch and options requiring the operator to get off the machine to use. The parking brake must be engaged with the operator in the seat for this option to work. The operator is then able to use machine options that require being off of the machine (i.e. Blower wand, Vacuum wand). Engaging the parking brake keeps the machine from moving.
This option should not be used on inclines greater than 2%.
Air conditioning
Air conditioning is available on units equipped with enclosed cabs. The air conditioning is mounted on the roof of the cab. The Air conditioning fan and temperature controls are mounted in the ceiling inside of the cab. The operator can control the direction of the air with integrated louvers in the blower outlets.
Heater
The heater option is mounted in the seat frame near the back of the operator’s legs. The three speed blower control (plus off position) for the heater is located on the side wall of the operator console near the operators left leg. To turn off the heat when it will no longer be required for long periods of time, there is a shut off located on the engine. The shut off is a “T” valve that can be shut down to prevent hot coolant to circulate thru the heater.
Cabin pressurizer
On units equipped with an enclosed cab, a Pressurizer is available. The Pressurizer mounts to the outside back of the cab and blows clean air in from behind the operator’s seat. The Pressurizer brings in outside air thru a removable filter mounted inside of its housing. The filtered air creates a positive pressure inside of the cab. This prevents dust from migrating into the cab as the machine is sweeping. There is a three speed blower control (plus off position) for the Pressurizer located on the operator console near the operators left leg. The Pressurizer filter should be cleaned or replaced every 50 hours or sooner depending on usage and environment.
Vacuum wand
This option takes the vacuum being created for the normal sweeping operation and allows it to be used for vacuuming debris that the machine’s brooms can’t reach. To use this option remove the yellow port plug in the hopper access door, by loosening the “T” handle. Plug in the vacuum hose to the port in the hopper access door.
Make sure the main broom handle is all the way back and locked so that the main broom is not on the ground as this might cause damage to the broom or the floor it is operating on.
Put the brooms lever in the “Main Broom Only” position, which will turn on the vacuum impeller. Press the hopper door close rocker switch to the on position, this will create more vacuum by sealing the hopper opening.
Make sure the hopper door is back in the open position before sweeping with the machine again.
Blower wand
The blower wand option take the vacuum impeller exhaust air and diverts it to a port that comes out at the rear of the machine. There is a hose and wand attachment that connects to the port. Once the hose is placed over the end of the port, the diverter cable may now be moved into the bypass position. The impeller exhaust air will now flow out of the hose and wand for moving debris that can’t be reached by the machine brooms. For this option to operate the machine must have the vacuum impeller operating at full engine RPM. The machine parking brake must be engaged, which activates the seat switch bypass switch so the operator may get of the machine and use the blower wand.
Caution: Never direct the wand toward bystanders or yourself.
Dual curb broom
The dual curb broom option adds a second side broom to the left front of the machine. The left side broom is activated by the left side broom rocker switch. When the switch is moved to the on position the left side broom is lowered by an actuator to the operating position. The brooms lever must be in the side brooms position for both side brooms to rotate. The side brooms may be lowered independently of each other but both brooms will turn when the brooms lever is move into the side brooms position.
Dust suppression system
The dust suppression system limits the amount of dust in the air around the machine while operating and aids in the sweeping process. The system has an air compressor, water tank and spray nozzle as the main components of the system. The water tank should be filled before operating the system and checked periodically during operation to make sure there is water for the spray nozzle. The system is controlled by the dust suppression system rocker switch. When this switch is moved to the on position the compressor will start and continue to run. There are two solenoids with the system one for the water and one for the compressed air. Both solenoids also turn on when the rocker switch is pressed on, which allows the air and water to come out of the spray nozzle in a fine mist pattern in front of the side broom. The spray nozzle is set at the factory so no adjustment should be necessary.

- Loosen the locking nut on each of the adjusting bolts on the side of the bracket closest to the pump mounting plate.
- From the operator's seat, start the engine and run at half throttle.
- Turn the adjusting bolts while watching the rear wheel. Continue to adjust until the rear wheel does not turn in either direction.
- Fully open the throttle. Push the directional control pedal forward and backward to be sure the pump stays in neutral. Check the wheel again and adjust as needed until the wheel remains motionless.
- Retighten all the locking nuts and bolts.
- Turn the engine off and lower the machine to the floor.
Sweep components
Broom door flap inspection
NOTE: Perform this inspection when the machine is parked on a level surface.
- Turn the machine off and lock the parking brake.
- Inspect broom door flaps for wear and damage. Flap clearance should be 0.125 in (0,3 cm) above the floor.
- Worn and damaged flaps should be replaced immediately to maintain proper dust control.
Broom door flap replacement and adjustment
The flaps are attached to the broom doors by a retainer bar, hex bolts and nuts. To remove the flaps, remove the nuts, bolts and retainer bar. To adjust the flaps, loosen the nuts and bolts, slide the flap up or down as needed. Retighten the nuts and bolts.
Main broom adjustment
NOTE: Perform this adjustment on a flat, smooth test surface.
- Drive the machine onto the test surface with the main broom in the RAISE position.
- Set the parking brake and position the main broom to the NORMAL position.
- Push the broom control switch to the ON position to activate the broom motor and open the throttle to full RPM.
- Allow about 45 seconds for the broom to operate, then deactivate the broom motor and raise the broom.
NOTE: Test time will vary according to the test surface used.
- Drive the machine clear of the test site.
- Examine the polished pattern made by the broom on the test area.
NOTE: A rectangular shape the length of the main broom, 2 in (5,08 cm) wide, indicates the main broom is properly adjusted. A pattern smaller then 2 in (5,08 cm) indicates need for lower adjustment. A pattern wider than 2 in (5,08 cm) indicates a need for higher adjustment. If pattern is tapered from end to end instead of rectangular, see Taper Adjustment on the next page.
Main broom height adjustment
- Turn the machine off and lock the parking brake.
- Position the main broom lever in the LOWER position.
NOTE: The adjustment knob is located in the engine compartment on the broom control handle pivot.
- Turn the broom adjusting knob clockwise one-eighth turn to free the wing nut.

- Grasp the main broom by the plastic drive hub, pull the main broom straight out and clear of the broom chamber.
- Depending on broom condition, you can either rotate the old broom end-to-end and re-install it or you can install a new broom. Slide the main broom into the broom chamber and align the broom with the metal drive hub located at the far side of the broom chamber.
If a worn broom is being replaced, install the new broom by first adjusting the broom arms up, to better match the position of the drive hub with the hub on the new broom.
- Once the broom is started onto the drive hubs, rotate the broom counter-clockwise while pushing lightly against the broom.
- Once the broom is fully engaged, replace the idler hub while aligning the seats in the idler hub with the broom's drive hub ears.
- Install the retaining bolt into position and tighten with the wrench.
- Close and latch the left broom door.
- Perform a main broom adjustment test and adjust as needed.
Side broom angle adjustment
The angle adjustment is controlled with a stop bolt. This stop bolt is located at the top front of the side broom arm (under the spring). To increase the angle of the side broom, loosen the jam nut and turn the stop bolt counter-clockwise. Be sure to retighten the jam nut back down once the adjustment is made.
Side broom height (wear) adjustment
The height of the side broom is adjusted with the use of a stop bolt located at the lower rear of the curb broom arm. As the side broom wears, it will be necessary to lower the arm.
Adjust side broom height
To lower the side broom, loosen the jam nut on the stop bolt. Turn the stop bolt in a counter-clockwise direction, check the side broom for proper contact and re-tighten the jam nut.
Side broom lift cable adjustment
This adjustment is made at the cable clevis attached to the side broom assembly. It controls the height of the side broom in the RAISED position. This adjustment must be made with the hopper fully lowered.
- Pull the side broom lever into the RAISED position.
- Loosen the locknut on the threaded rod at the clevis.
- Turn the threaded rod in or out to set the side broom in the maximum raised position.
- Secure the cable adjustment by tightening the locknut.
Side broom replacement
NOTE: Broom should be replaced if bristles worn to a length of 3 in (7,6 cm) or less.
NOTE: The side broom features a quick release mechanism which enables the operator to remove the brush in seconds.
- Raise the side broom and lock in the RAISE position.
- Turn the side broom by hand until the brush retainer bar is accessible.
- Lift the bar and turn the broom clockwise (about one eighth of a turn) until the lock pins in the broom disengage from the drive plate.
- Install the new broom by positioning the three drive pins into the pilot holes of the drive plate.
- Lift and rotate the broom until the broom retainer bar springs into the locked position.
- Check to make sure all three drive pins are properly engaged.
Hopper
NOTE: It is not usually necessary to remove the hopper on high dump models. However, if it becomes necessary for maintenance or to install an option, use the following procedure to remove:
High dump hopper removal
- Park the machine on a level surface and engage the parking brake.
- Raise the hopper and position the high dump hopper dolly, a platform truck or similar four wheeled cart under the hopper.
- Set the hopper down on the truck and turn the engine off.
- Cycle the rotation control handle (#2) in both positions to relieve any residual hydraulic pressure.
- Remove three bolts, washers, nuts and backing plate.
- Disconnect the wire harness connections at the right side of the hopper.
- While spreading the dump arms slightly, roll the hopper away from the machine.
High dump hopper replacement
- Position the hopper on the dolly so as to align the mounting holes in the sides of the hopper with the rotation mounts on the arms. Lift arms should be positioned about ⅓ of the way up.
- Engage the lift arm rotation plates with the mounting bolts on each side of the hopper.
- Start the machine and lift the hopper.
- Drive away from the hopper dolly or cart.
- Lower the hopper.
- Engage the wire connections at the right side of the hopper.
Floor clearance and dump angle adjustment
NOTE: In order to perform properly, the hopper must maintain a distance of 3.5 in (8,9 cm) from the floor to the rear hopper entrance lip. The front of the hopper should be adjusted so that the front bumper aligns with the hopper frame where the two meet. When properly adjusted, the front edge of the hopper will be 5 in - 6 in (12,7 cm - 15,2 cm) from the floor.
- Park the machine on a level surface, shut off the engine and engage the parking brake.
- Adjust the lift arm stop bolts located on top of the wheel wells as low as possible while still allowing the side broom assembly to clear the lift arms when the hopper is in the NORMAL position. Be sure that both lift arms contact the stop bolts at the same time.
NOTE: This may involve raising and lowering the hopper several times.
Hopper clearance diagram
- After adjustment, with the hopper down, use the two adjustable stops located on the rotation plates on both sides of the hopper to establish 3.5 in (8,9 cm) clearance between the rear hopper entrance lip and the floor.
NOTE: The stop on the driver's side is located immediately below the cylinder rod end and is threaded into the cylinder mount arm. The stop on the left side is located directly above the arm rotation plate.
- After the 3.5 in (8,9 cm) clearance is established, make sure both stops make contact simultaneously. The lower front edge of the hopper should be 5 in - 6 in (12,7 cm - 15,2 cm) from the floor. A balanced adjustment of both sets of adjustment bolts is required to correctly adjust the hopper in the lower position. If the bumper is lower than the frame, after the hopper is correctly adjusted, loosen the bumper attachment bolts and reposition the front bumper.
- Raise the hopper and rotate fully.
- Turn the engine off.
- Adjust the rotation cylinder stops on the hopper rotation arms on each side of the hopper so that clearance between the lift arms and the cut-outs in the bumper is 0.25 in (0,63 cm) maximum.
- Loosen the locking set screw in the bottom side of the rotation block.
- Using the hole in the cylinder rod, turn the rod to adjust the cylinder extended length to match the hopper rotation stops.
- Tighten the set screw.
- Rotate the hopper back, remove the safety arm and lower the hopper.
Hopper filter removal (dual filter)
- Release the latch on the hopper cover and raise the cover.
- Disconnect the wire harness connector leading to the filter shaker motor.
- Unscrew the four wing nuts (each having one conical washer and an isolator) securing the filter retainer bars to the hopper.
- Remove the shaker motor assembly and filter retainer bars.
- Lift out the panel filter.
Filter removal steps are the same for both filters.
Filter cleaning
The dust control filter is a polyester type element filter. It may be vacuumed, blown out with compressed air, tapped against the floor or washed with soap and water.
- If blown out with compressed air, use 100 psi (689 kPa) or less.
- If washed with soap and water, use 40 psi (275 kPa) water pressure or less.
NOTE: Make sure the filters are thoroughly dried while standing on their side before installing in the hopper. Do not install or use a wet filter.
Filter replacement
- Insert the panel filter.
- Install the shaker motor assembly.
- Install and tighten the four filter wing nuts, washers, and isolators.
- Reconnect the wire harness connector to the filter shaker motor.
- Close the hopper cover and secure the latch.
Vacuum gasket mount adjustment
- With the hopper in the normal position, observe contact between the back of the hopper and gasket. If complete seal is not maintained, raise the high dump hopper.
Loosen the mounting bolts in the gasket mount. Move the assembly toward the hopper. Tighten the bolts. Test and repeat if necessary.
Flap replacement
Flaps located at the entrance lip and on the sides of the hopper must be replaced when worn or damaged. The flap panels may be replaced separately.
- Park the machine on a level surface and engage the parking brake.
- Raise the hopper.
- Turn off the engine
- Remove the flap retaining angle and worn or damaged flaps.
- Install the new flaps.
- Replace the retaining angle.
Frame seal replacement
Front frame seal
The hopper frame seal bolts to the front edge of the engine pan. Install a new seal by folding it in half to align the holes. Doubled edge with holes goes on the bottom. Support the seal straight up while bolting the retainer bar in place. The seal should fall over the retainer bar after installation. Be certain that the seal edges are aligned to prevent twisting of the seal.
Side frame seal
The side frame seals should clear the floor by at least .125 in (0,32 cm). If the bottom of a side seal measures .50 in (1,27 cm) or more above the floor, readjust it or replace it by removing the bolts on the inside of the wheel wells, installing a new seal, and securing it with the bolts. The double edge with the holes goes toward the front.
Parking brake
Normal adjustment of the parking brake can be accomplished from the operator compartment. Locate the knurled handle on the parking brake lever. Turn the handle clockwise to increase brake tension.
NOTE: Two or three turns is usually adequate. DO NOT OVERTIGHTEN.
If this adjustment becomes ineffective, it will be necessary to adjust the cable length.
Adjusting the parking brake cable length
- Park the machine on a level surface and chock the wheels.
- Place the parking brake lever in the "OFF" position.
- Turn the knurled handle counter-clockwise as far as possible.
- Raise the hopper and engage the safety arm.
- Locate the cable clevis ends for the parking brake cables.
- Disconnect the clevis ends from the bar.
- Loosen the jam nuts at the base of the clevis.
- Turn the clevis clockwise three or four complete turns.
- Tighten the jam nuts and re-install the clevis ends onto the bar.
- Adjust the knurled handle on the parking brake lever.
Tires
Changing solid tires
NOTE: The procedures which follow apply to SOLID TIRES ONLY.
- Remove the tire from the vehicle by removing the five inner lug nuts.
- Remove the ten hex head bolts and nuts.

Miscellaneous adjustments
Anti-static chain adjustment
Each machine is equipped with an anti-static chain bolted to the back wall of the broom chamber. This should remain in contact with the floor at all times. Inspect the chain every 200 operating hours. Replace if at least one link does not drag the surface of the floor.
Latch and hinge maintenance
Latches and hinges should be inspected after every 500 hours of use. Retighten and oil if necessary.
Cables
Inspect all cables for wear every 500 hours.
