Air cleaner
General
The air cleaner prevents dust and other impurities from entering
the engine. The air first passes through the primary filter and then
the secondary filter.
The degree of engine wear depends largely on the cleanliness of
the induction air. Therefore, it is very important that the air cleaner
should be checked regularly and maintained correctly. Observe
great cleanliness when working with the air cleaner and filters.
IMPORTANT
Do not, under any circumstances, run the engine without a
filter or with a damaged one.
Check regularly that hose and pipe connections from the air clean-
er to the engine induction manifold do not leak.
Always have a spare air filter at hand and keep it well protect-
ed from dirt.

Cleaning of cover for air cleaner
The cover for the air cleaner should be cleaned when the air
cleaner clogging warning lamp lights up.
NOTE :
Under dusty and wet conditions, the cover should be cleaned
daily.
Proceed as follows:
1 Remove valve (A) from the air cleaner.
2 Empty and clean the valve.
3 Reinstall the valve on the air cleaner.
Primary filter (B)
General
Replace or clean at least every 2000 hours or when the warning
lamp is ON.
The filter may be cleaned, at the most, six times. Thereafter, the
filter should be replaced. Also replace the filter if it is damaged.
If the control lamp is still ON after replacing/cleaning, the second-
ary filter must be replaced.
NOTE :
The secondary filter must not be cleaned but only replaced,
See Changing secondary filter on page 141.
As the length of time between filter replacements depends entirely
on the operating environment of the machine, it may sometimes be
necessary to replace the filter more often.
