OPERATION 22
Clean the Cab Air Filter
The cab air filter, 1, located on the rear of the c ab
must be cleaned to keep the cab air system
operating at maximum efficiency.
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 remove the cab air filter, lift up on the filter
frame handle, 1, and unhook the latch, 2. Allow

window. Remove the filter element. The filter
element may be cleaned using either method A

METHOD A
Clean the element with compressed air not
exceeding 2 bar(30 PSI). Holdthe 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.
