Section 5 - General Maintenance (continued)
5G - Cleaning the air filter
(figures 30a to 30d):
The filter elements should be replaced in following cases:
The filter elements are ‘clogged -up’.
The filter cores have been damaged.
The indicator lamp on the instrument panel lights-up, this means that the filter elements should be cleaned or replaced.
Dirty or damaged filter elements will cause insufficient power and possible damage to the engine.
In order to ensure the service life and normal operation of the engine, the air filter MUST BE regularly and carefully
maintained.
Under normal operating conditions the air filter should be checked and maintained after the vehicle has been driven for
each 15,000 km. When the vehicle operates in heavy dust conditions, the checking and replacement period of the filter
elements MUST be greatly reduced accordingly.
The engine must be turned off when the filter system is being maintained.
Release the lock lever, twist and turn to remove the cover; then take out the large filter element ONLY.
DO NOT start the engine after the filter has been removed.
Clean the cover and the inside of the shell using a dry, clean cloth.
Do prevent water entering the air filter directly.
Expel the dust in the blurter valve.
Clean the filter elements by using compressed air at maximum 2.5bar to lightly blow the dust off without tearing the
paper element. The elements may be washed, but please check with the manufacturer for the correct procedure.
NOTE: DO NOT damage the paper elements.

Using compressed air to blow the filter elements
:
Use compressed air with a pressure not exceeding 2.5 bar from inside to outside until there is no dust remaining.
Caution
:
DO NOT blow the outside surface of the filter elements using compressed air. Clean the surface using a piece
of cloth.
The filter elements should be visually checked with the aid of a lamp to make sure that there is no damage before re-
installing them.
Also check for damage or cracks on the sealing ring.
Note: DO NOT start the engine without the air filter and elements fitted.
AFTER ANY MAINTENANCE ON THE FILTER SYSTEM – IT IS ESSENTIAL THAT PERSONNEL ENSURE THE FILTER
COVER IS CORRECTLY SECURED.
