Air filter maintenance
Warning
Do not use diesel or solvents with a low evaporation point to clean the
air filter element as it could catch fire or explode.
Important
If the air filter is dirty this reduces the flow of air to the engine. Therefore,
to prevent malfunctions we recommend checking the state of the filter
periodically, and more often if you are using the TEC 40D in particularly
dusty areas.
Never use the engine without the air filter. The engine would wear
quickly.
Operations:
Remove the air cleaner cover.
Unscrew and remove knurled nut and take off air cleaner element.
Clean the filter compartment and the cover.
Dirt and other foreign bodies must not be allowed to enter the engine’s
air inlet points.
The filter cartridge should either be renewed or, depending upon the
degree of contamination, cleaned, or checked, as follows:
Cleaning the filter cartridge
Dry contamination
Use compressed air to blow through the filter cartridge from the inside outwards, until no further dirt emerges.
Important ! The pressure must not exceed 5 bar.
Moist or oily contamination
Renew the filter cartridge.
Checking the filter cartridge
Check filter cartridge’s gasket surface for damage, Check the filter cartridge for cracks or any other type of damage to the paper filter by holding
it inclined towards the light or by shining a light source through it.
Important ! The slightest damage to the paper filter rules out it being used any longer. Re-assemble the filter cartridge in the reverse order of
work.
