The amount of dirt in the air cleaner de-
pends on the amount of dust in the air and
the size of the air cleaner used. If a high
level of dust is anticipated, a cyclone-type
precleaner can be fitted to the air cleaner.
Cleaning intervals will have to be deter-
mined from case to case.
If dry type air filters are used, cleaning
should only be carried out according to the
service indicator or service switch.
