General Maintenance
109
Model 944E
Origin 3/04
The optional closed cab has two air filters. These filters require periodic
maintenance.
Recirculation Air Filter
Periodically remove and inspect the recirculation air filter (7) located directly behind
the seat. Remove the two thumb screws (8) holding the vent cover and filter (7) to
the heater assembly housing (9). Gently hand wash with water. A mild detergent
may also be used if the filter is saturated with dirt.
Fresh Air Intake Filter
The fresh air intake filter (10) cleans outside air when pressurizing the cab. Check
the condition of the filter by removing the recirculation filter to gain access to the
fresh air filter. Pull the fresh air filter out of the pocket in the heater assembly
housing.
When operating in normal conditions, inspect the filter weekly. When operating in
extreme conditions, inspect the filter daily. Clean the filter by removing the filter and
shaking it. Be sure the filter is seated all the way into the pocket in the heater
assembly housing. Reassemble the recirculation filter to the heater assembly
housing.
The filter should be replaced at 250 hour intervals under normal operating conditions
and at 50 hour intervals under extreme operating conditions.
NOTE:
Correctly position the filter so the air flow is directed into the cab.
