Cartridge (Panel) Filter
To insure continued maximum efficiency of the dust control
system on your sweeper, the cartridge filter should be removed
and cleaned often. The frequency of this cleaning is related to
the sweeping appliaction; i.e., the dustier the area is, the more
frequently the filter should be cleaned.
Cleaning Panel Filter
Remove from machine and tap gently on flat surface, dirty side
down. (See Fig. 5)
OR
Use compressed air (100 psi maximum), directing it through
the panel opposite the direction of the arrows.
OR
Soak for fifteen minutes in water and a low-foaming, mild
detergent. Rinse with water until clean (maximum 40 psi).
Air Dry - Do not use compressed air.
Accordion Type Cloth Filter (Optional)
To insure continued maximum efficiency of the dust control
system on your sweeper, the cloth type filter should be
frequently shaken (See Fig. 6) using the handles provided.
The dustier an area is, the more often the shakedown should
be done. The dust hopper should then be emptied.
How to Clean the Cloth Filter
Remove filter assembly from the machine. Direct com-
pressed air through material opposite the normal air flow
direction. (See Fig. 7)
OR
Wash with a mild low-foaming detergent and water. Let dry
thoroughly before putting back into service.
NOTE: This filter is treated wuth a flame retardant chemical.
The washing method of cleaning neutralizes and/or
eliminates this resistance to burning.
