DEBRIS HOPPER AND DUST FILTER
DEBRIS HOPPER
The debris hopper collects debris swept by the
machine. It should be dumped after every work
shift. It should also be flushed out after every 100
hours of operation. The hopper floor clearance
should be checked and adjusted if necessary after
every 100 hours of operation.
TO CHECK AND ADJUST HOPPER FLOOR
CLEARANCE
1. Empty the hopper and park the machine on
a smooth, level surface.
2. Place the hopper in the “operating” position.
3. Stop the motor and set the parking brake.
FOR SAFETY: Before Leaving Or
Servicing Machine; Stop On Level
Surface, Set Parking Brake, And Turn
Off Machine.
4. Check the distance between the floor and
the bottom edge of the hopper. It should be
equal side to side. To adjust the hopper floor
clearance, raise the hopper and adjust the
hopper stop bolts. A good starting point is to
adjust both bolts so they extend 1.25 in
(30 mm) from their mounting position.

HOPPER DUST FILTER
The hopper dust filter filters the air which is drawn
up from the main brush compartment by the
vacuum fan. It is located inside the dust filter
compartment. Shake the excess dust from the
filter daily. Inspect and clean or replace the dust
filter after every 50 hours of operation.
To clean the dust filter use one of the following
methods:
D
TAPPING -- Tap the filter gently on a flat
surface with the dirty side down. Do not
damage the edges of the filter element or
the filter will not seat properly in the filter
frame.
D
AIR -- Blow compressed air, 35 psi (240
kPa) maximum, through the dust filter
opposite the direction of the arrows. This
may be done with the filter in the machine.
Always wear eye protection when using
compressed air.
D
WATER -- Soak the dust filter in a water and
mild detergent solution. Rinse the dust filter
until it is clean. The maximum water
pressure allowable is 40 psi (275 kPa). Air
dry the wet filter; do not use compressed air.
NOTE: Be sure the dust filter is dry before
reinstalling it in the machine.
