Engine air cleaner
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.
NOTICE
Do not, under any circumstances, run the engine
without a filter or with a damaged one. Always have
a spare filter at hand and keep it well protected from
dirt.
Check regularly that hose and pipe connections
from the air cleaner to the engine induction manifold
do not leak.
Engine air cleaner primary filter,
cleaning and replacing
Clean the filter when the check screen for engine
air filter clog pops up on the I-ECU. The filter may
be cleaned, at the most, five times. Thereafter or
after maximum 1 year, the filter should be replaced.
Also replace the filter if it is damaged
NOTE!
Do not clean the filter if the check screen does not
pop up on the I-ECU.
NOTE!
Use Volvo genuine air filters. Otherwise Volvo may
not support the engine failures.
If the indicator is still alight after replacing or
cleaning the primary filter, the secondary filter must
be replaced.
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.
