MAINTENANCE MANUAL
3.6.30. How to replace air filter elements
The proper maintenance of air filter and of the entire inlet piping, the rubber parts in particular, will ensure maximal protection of the
engine against dust effects, and prolong the life of the element and its efficiency.
The inherent sign of fouled filter is the exhaust pipe that smokes, higher fuel consumption, output loss and engine temperature in-
creased.
Principles of correct filter element replacement:
Slowly pull out the clogged element as carefully as possible. •
Always clean the inner bodies of the cleaner in a way to avoid dust penetrating inside the engine feed piping. •
Clean the seating faces for gasket in the cleaner body. •
Examine the dust traces in the element removed, any traces would be an indication of its leakage in the filter body. •
Press the gasket on the new element, whether it is flexible. •
Make sure the gasket is seated properly. •
How to replace air filter element:
The air filter comprises the main element and safety ele- •
ment.
Replace the main element always when signalled by indica-
•
tor lamp for air filter fouled.
Replace the safety element always following the three re-
•
placements of the main element.
Confirm the fixing and integrity of the air filter and intake
•
piping.
Saturation of the air filter element will be signalled by the
•
indicator lamp for air filter fouled.
When the indicator lamp goes on you must replace the main
•
filter element.
Remove filter cap (1) and replace the main filter element (2) •
from the filter shell.
NEVER use damaged elements!
Do NOT use other elements than those required!
Do NOT remove the elements just for checking purposes!
Do NOT left the filter opened longer than necessarily required!
