5. LUBRICATION SCHEDULE
Refer to the following table for correct sweeper lubrication.
6. FILTERS
Because of the dusty conditions under which a sweeper operates, filters are considered a priority maintenance
item. Failure to properly follow filter change schedules may result in poor performance or costly component
replacement.
6.1 Hydraulic Tank Filters
The hydraulic tank has a single in-tank return filter, to remove foreign particles from the hydraulic oil that might
cause failure in the hydraulic system’s components.
6.2 Dust Suppression System Filter
Water filter maintenance is an important part in keeping the sweeper’s water system functioning properly. The
strainer should be emptied and its strainer screen flushed and cleaned daily. However, the frequency of filter
cleaning varies and largely depends on the purity of the fill source’s water.
7. SEALS
It is important that the sweeper’s seals on the fan housing be kept in the best condition possible. These include
the seals on the suction hose inlet, around the hopper’s inspection door opening and on the rear door. Pickup
power is vacuum-dependent, so a tight seal can make a significant difference in pickup ability. Maintain
resilience by keeping the seals well lubricated with a good grade of petroleum-based jelly or grease.
It is not necessary to lubricate the side inspection door seals, dump door and roof access door.
For longer seal life, when the sweeper is parked for an extended period of time, leave the hopper raised
several inches so the fan and intake seals can regain their shape.
Eventually the seals will become worn or non-resilient and must be replaced. When this occurs, a loss of
vacuum power results. To maintain sweeping efficiency, replace these seals periodically.
