HOPPER DOOR SEALS
The hopper door seals prevent debris from spilling out of the hopper before dumping. There are two hopper door side seals, one hopper door lower seal and one hopper door upper seal. The upper seal can only be replaced by removing the hopper door from the hopper. The hopper door seals should be inspected for wear or damage daily. They do not require adjustment.
REPLACING DOOR SEALS
1.Empty the debris hopper.
2.Park the machine on a smooth, level floor.
3.Raise the hopper and engage the hopper safety arm.
Raised hopper may fall. Engage hopper safety arm.
4.Partially open the hopper dump door so that both sides of the hopper door can be accessed.
5.Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing machine, stop on level surface, apply parking brake, turn off machine and remove key.
6.Remove the retainer bar from the worn or damaged seal.
7.Remove the old seal and place the new seal in position.
NOTE: When replacing the lower door seal, a new seal cord must be used.
8.Replace the seal retaining bar. Replace and tighten the screws.
HOPPER
The hopper holds debris swept by the main broom. The hopper should be dumped after each day of operation and cleaned every 200 hours of operation. For efficient sweeping, the correct hopper floor clearance must be maintained.
1.Empty the hopper.
2.Park the machine on a smooth, level floor.
3.Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing machine, stop on level surface, apply parking brake, turn off machine and remove key.
MAINTENANCE
4.Check the distance from the lower rear edge of the hopper to the floor. The correct clearance is 2 inches (51 mm). The clearance should be equal from side to side. A good method for checking this clearance is to slide a 2 inch (51mm) high bar under the hopper.
5.If necessary, loosen the two rear hopper attachment bolts, raise or lower the rear of the hopper to obtain the correct floor clearance, and tighten bolts.
HOPPER DUST FILTER
The hopper dust filter cleans the dust laden air that is drawn up from the hopper by the vacuum impeller. The filter is located above the hopper and is accessed by raising the filter cover. The filter should be cleaned daily by pressing the filter shaker button for
TO REMOVE AND REPLACE HOPPER DUST FILTER
