Procedure 15. Checking the Engine
Air Cleaner
Check the condition of the paper filter
elements (PFE) for paper rupture and
correct insertion.
To check the basic filtering element
(BFE), proceed as follows:
• screw out the butterfly nut (2) and re-
move the sump (1);
• screw out the butterfly nut (3) and re-
move the BFE (5);
• check the monitor filtering element
(MFE) (4) for contamination without
withdrawing it from the housing (6).
ATTENTION ! It is not recommended to
take the filter element (4) from out of
the housing (6).
Contamination of the monitor filter ele-
ment is indicative of a damaged basic
filter element (BFE) – rupture of the pa-
per shutter, unstuck bottom. In this case,
flush the MFE and replace the BFE.
NOTE: Under heavy dust-laden condi-
tions, this procedure should be per-
formed every 20 hours of the engine
operation.
