OPERATION 22

Clean the Cab Air Filter

The cab air filter, 1, located on the rear of the cab 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 the filter and frame to lower toward the cab window. Remove the filter element. The filter element may be cleaned using either method A or B depending on the condition of the element.

METHOD A

Clean the element with 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.
