CLEAN AIR CONDITIONER AIR FILTER (FRESH/RECIRC FILTER) 4
(Machine equipped with cab)
Clean the air conditioner air filter if it becomes clogged or if there is dirt or oil stuck to it.
In places where there is a lot of dust, clean the air filter once a week. In addition, clean the air conditioner air filter
at the same time, when cleaning the engine air cleaner.
1. Loosen mounting bolts (1), pull up inspection cover (2) to
the rear, and remove it.
2. Remove inside cover (3), then remove FRESH filter (4).
3. Remove the filter box, then brush out the dirt accumulated
inside the box through the cleaning hole (5) in the hood.
When doing this, be careful not to let any dirt or dust get
into the fresh air intake port (6) leading to the cab.
4. Open inspection cover (7) under the front panel, then pull
up RECIRC filter (8) and remove it.
5. Clean filters(4) and (8) with compressed air.
If the filters are stained with oil or extremely dirty, wash
them in neutral detergent.
After washing the filters, dry them up, then install them.
REMARK
If the filters cannot be cleaned with air or in water, replace them
with new ones.
