DEBRIS HOPPER
HOPPER DUST FILTER
The dust filter filters the air pulled up from the
hopper. The dust filter is equipped with a shaker
to remove the accumulated dust particles. The
dust filter shaker is operated by the filter shaker
switch.
The standard dust filter works well for normal
sweeping applications. The synthetic filter works
well for humid or wet applications.
Shake the dust filter before emptying the hopper
and at the end of every work shift. Check and
clean or replace the dust filter every 100 hours of
operation.
To clean the dust filter, use one of the following
methods:
D
SHAKING -- Press the filter shaker switch.
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 -- Always wear eye protection when
using compressed air. Blow air through the
dust filter opposite the direction of the
arrows. Never use more than 690 kPa
(100 psi) of air pressure and never closer
than 50 mm (2 in) away from the filter. This
may be done with the dust filter in the
machine.
FOR SAFETY: When servicing machine,
wear eye and ear protection when using
pressurized air or water.
D
WATER -- Rinse the synthetic filter with a
low pressure garden hose through the dust
filter opposite the direction of the arrows.
The standard dust filter can also be rinsed,
but the filter will degrade with each rinsing
and should be replaced after rinsing five
times.
NOTE: Be sure the dust filter is dry before
reinstalling it in the machine.
