DEBRIS HOPPER
HOPPER DUST FILTER
The dust filter filters the air which is drawn up from
the main brush compartment through the hopper.
The dust filter is equipped with a shaker motor to
remove the accumulated loose dust particles. The
dust filter shaker motor is operated by the filter
shaker switch. Shake the dust filter before dumping
the hopper and at the end of every work shift.
Inspect and clean or replace the dust filter after every
100 hours of operation.
To clean the dust filter, use one of the following
methods:
* 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.
* 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 dust filter in the machine. Always wear eye
protection when using compressed air.
* 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
dust filter; do not use compressed air.
NOTE: Be sure the dust filter is dry before reinstalling
it in the machine.
