MAINTENANCE
HOPPER SEALS
The hopper seals prevent dust from exiting around the hopper where it meets the broom chamber. There are two side hopper seals and one upper hopper seal. These seals should be inspected for wear or damage daily. When correctly adjusted, the two hopper side seals should clear the floor by 0 to 1/8 inch (0 to 3mm).
REPLACING THE HOPPER SEALS
1.Park the machine on a smooth, level floor.
2.Raise the hopper and engage the hopper safety arm.
Raised hopper may fall. Engage hopper safety arm.
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.
4.Remove the retaining bolts and retaining bar.
5.Replace the worn hopper seal with a new seal.
6.Install the retaining bar and bolts.

HOPPER LIP SKIRTS
The hopper lip skirts seal the area between the lip of the hopper and the floor. They also help deflect debris into the hopper. The lip skirts should be inspected for wear or damage daily. The lip skirts do not require adjustment. They should be replaced when the lower edge is worn down to the “Perform Alert™” wear indicator line.
REPLACING THE HOPPER LIP SKIRTS
1.Empty the debris hopper.
2.Park the machine on a smooth, level floor.
3.Raise the hopper and engage the hopper safety arm.
