OPERATING INSTRUCTIONS
WARNING!
Do not turn the steering wheel sharply when the machine is in motion. The sweeper is very
responsive to movement of the steering wheel. Do not make sudden turns.
Sweep in straight paths. Do not bump posts. Do not scrape the sides of the machine.
When the machine is in motion, do not push the directional/speed control pedal all the way forward. This is the same as starting in “High”
and will put a strain on the motor and drive system.
1. Plan your sweeping in advance. Try to arrange long runs with minimum stopping and starting. Sweep debris from narrow aisles
out into main aisle ahead of time. Do an entire floor, or section at one time.
2. Pick up oversize debris before sweeping.
3. Don’t turn steering wheel too sharply when machine is in motion. The machine is very responsive to movement of the steering
wheel - so avoid sudden turns.
4. Try to follow as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine.
5. When placing the machine in motion, avoid slamming the directional control pedal all the way forward quickly. This is equivalent
to starting out in “HIGH” and puts needless strain on the engine and drive system.
6. Always allow the machine to warm up before operating in cold temperatures.
7. Periodically turn sweeping (main) broom end for end to prevent the bristles from “setting” in one direction.
NOTE
Replace sweeping broom when bristles are worn to 3-inch (8-cm.) length.

2. To open hydraulic circuit to wheel drive motor turn shaft
90°.
3. After towing, turn shaft 90° to its original position.
DUST FILTERS
The Filter Panel can be periodically removed from the hopper and blown off with compressed air (not to exceed 100 P.S.I.) or cleaned
with soap and water. (Do not attempt to use Filter Panels that have not dried completely.)
THE DUST CONTROL SYSTEM
The baffle system that is built into the debris hopper is designed minimize dust in the air while the machine is sweeping.
The debris from sweeping is thrown into the hopper. The impeller vacuum fan pulls the lighter dust up and through a baffle system.
The Pre-Clean Flap separates the heavier dust particles to an area below the filter. The lighter dust particles are captured by the dust
filter. This allows the dust filter to remain cleaner and need less shaking to remove dust. When the dust filter becomes clogged the
filter shaker switch should be pushed to start the dust shaker cycle. This will extend the life of the filter.
NOTE
The main broom and impellor fan will shut off automatically when the shaker motor is cycling.

14. Put the broom lever in the “UP” position.
15. Back the machine off the test spot.
16. Inspect the polished area where the broom swept, for broom bristle contact with the floor. The area of broom bristle contact with
the floor should be 2 to 3 inches or 5 to 8 cm. wide.
MAIN BROOM LEVEL ADJUSTMENT
The main broom level is factory set and should not need adjustment, if the level gets out of adjustment and the broom bristle contact
pattern is not an even 2” to 3” wide, the broom arm lift frame will have to be adjusted. The frame is supported by two flange bearings.
These bearings are located inside the broom doors. The carriage bolts on the two end flanges will have to be loosened. The frame
can then be leveled and the bolts tightened.

HOW TO ADJUST MAIN BROOM WEAR PATTERN
When the bristles of the broom begin to wear out the following adjustments may be made to keep a 2 inch (5 cm) broom pattern.
1. Loosen the wing nut located in the engine compartment.
2. Set the broom lever to the “Sweep” position and adjust the torque knob to obtain a 2 inch (5 cm) broom pattern. The torque knob
will move the linkage rod that adjusts the sweeping pattern of the broom for wear.
3. Tighten the wing nut against the torque knob.
SIDE BROOM LEVEL ADJUSTMENT
As the side broom wears, simply loosen the two wear adjusting bolts and slide the broom-motor assembly into a position so that the
broom contacts the floor at a 3 degree angle when lowered.
SIDE BROOM REPLACEMENT
Put the side broom lift control in the “UP” position. Remove the retaining screw in the bottom middle of the side broom. Remove the
side broom. Transfer the side broom flange, spacer, screws, washers, and nuts to the replacement side broom. Put the replacement
side broom on the shaft. Put the retaining screw and washer in position and tighten.
BROOM FLAPS
The Urethane Flaps are susceptible to damage and should be inspected regularly and maintained in good condition. The side and
hopper flaps are adjustable and should be maintained even with the floor. The rear flap must be maintained 1/16” (16 cm.) above the
floor. All flaps should be replaced when worn or damaged to such an extent that they cannot perform their normal function.
