6.4.1 Cleaning Intervals
● The amount of dirt in the air cleaner depends on
the amount of dust in the air and the size of the
air cleaner used. If a high level of dust is antici-
pated, a cyclone-type precleaner can be fitted to
the air cleaner.
● Cleaning intervals will have to be determined
from case to case.
● Air cleaner servicing is needed when:
– Service indicator
the red signal 1 is fully visible when the
engine is off.
– Service switch
the yellow pilot light comes on when the
engine is running.
● After carrying out service work, reset the signal
by pressing the button on the service indicator.
