Safety filter – Replacement
Replace or clean the air cleaner’s main filter if
the warning lamp on the instrument panel lights
up when the diesel engine is operating at full
speed.
Undo the three locking braces (1). Then pull off the
cover (2) and pull out the main filter (3).
Do not remove the safety filter (4).
If the main filter is to be cleaned, compressed air at
max. 5 bar (72 lbs/sq in) pressure should be used.
Blow up and down along the paper creases on the in-
side of the filter.
Hold the nozzle at least 2–3 cm (0.8-1.2 in) away from
the paper creases so that the paper does not tear un-
der the pressure of air.
Use protective goggles when working with
compressed air.
Dry the inside of the cover (2) and filter housing (5).
Check that the hose clamps between the filter
housing and inlet hose are tightened and that
they do not leak. Check the entire length of the
hose all the way to the engine.
Once the main filter has been cleaned a maxi-
mum of 5 times, it must be replaced.
Replace the safety filter with a new one at every 5th
replacement or cleaning of the main filter. The safety fil-
ter cannot be cleaned.
When replacing the safety filter (4), pull out the old filter
from its holder, insert a new one and refit the air cleaner
in the reverse order to the instructions given in the
figure above.
