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 (A) out into
main aisle (B) 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.

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.

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.
