In case of use in a heavily dust laden atmosphere, there are pre-filtration
cartridges (See FILTERS CARTRIDGES AND BELTS in SECTION 3 -
MAINTENANCE). Also, checking and cleaning the cartridge must be
increased (up to 250 hours in a heavily laden dust atmosphere with pre-
filtration).
- Open the I.C. engine compartment.
- Loosen the bolts and remove cover 1 (Fig. D3/1).
- Gently remove the cartridge 2 (Fig. D3/1), taking care to avoid spilling the
dust.
- Leave the safety cartridge in place.
- The following parts must be cleaned with a damp, clean lint-free cloth.
• The inside of the filter and cover.
• The inside of the filter inlet hose.
• The gasket surfaces in the filter and in the cover.
- Check pipes and connections between the air filter and the I.C. engine and
the connection and state of the clogging indicator on the filter.
- Before mounting check the state of the new cartridge (See FILTERS
CARTRIDGES AND BELTS in SECTION 3 - MAINTENANCE).
- Introduce the cartridge into the filter axis and push it in, pressing the edges
and not the middle.
- Reassemble the cover, guiding the valve (Fig. D3/2).
