CLEAN CAB AIR FILTER
Before servicing the filter, switch off the blower and
close all windows and one door. Forcibly close the
other door. The resulting back pressure will dislodge
most of the loose dirt from the underside of the filter.
NOTE: In humid conditions, such as occur on most
early mornings, do not switch on the blower prior to
servicing the filter. Damp particles drawn into the
filter may be difficult to remove without washing.
NOTE: The filter is made of specially treated paper
with a rubber sealing strip bonded to the upper
surface. Do not damage the element during removal.
To clean the filter:
1. Loosen the filter cover retaining screw, 1.
2. Lower the front of the filter cover, 2.
NOTE: The filter cover is hinged at the rear.
3. Remove the filter element, 3.
4. Clean the filter using compressed air not
exceeding 2 bar (30 PSI). Hold the nozzle at least
300 mm (12″) from the filter to prevent damage
to the paper pleats. Direct the compressed air
through the filter opposite the normal air flow.
5. Clean the filter chamber with a damp, lint-free
cloth.
6. Install the filter with the rubber seal, 4, facing the
cab roof.
7. Close the front of the cover and tighten the
retaining screw.
NOTE: The filter should be cleaned more frequently
when operating in extremely dusty conditions.
WARNING
The cab air filter is designed to remove dust from
the air but will not exclude chemical vapor.
Follow the chemical manufacturers directions
regarding protection from dangerous chemicals.
