Change Air-Conditioning Outer Filter
The unit is equipped with an air filtration system which filters out
dirt and dust particles from air being circulated into operator's
cabin. This filter should be cleaned out.
NOTE:
In the event that the unit is being operated in a dusty
environment, the cleaning and replacement should
be performed more frequently. If filter is damaged,
replace damaged filter with a new one.
All service and inspection of air-conditioning system
should be performed with the starter switch in the "O"
(OFF) position.
NOTE: All right and left call outs are based on the operator
being seated in the operator's seat facing the front.

four wing bolts and washers, and access cover (1, Figure 80).

the rear of the cabin.
3. Remove filter (Figure 82) and replace with new one.
