D3 - DRY AIR FILTER CARTRIDGE
CHANGE
In case of use in a heavily dust laden atmosphere, there are pre-filtration car tridges, see:
3 - MAINTENANCE: FILTERS CARTRIDGES AND BELTS. Also, the checking and cleaning
periodicity of the car tridge must be reduced (up to 250 hours in a heavily laden dust
atmosphere and with pre-filtration).
Change the cartridge in a clean location, with the I.C. engine stopped. Never operate the lift truck with
the air filter removed or damaged.
- Open the I.C. engine bonnet.
- Loosen the bolts and remove cover 1 (fig. D3).
- Gently remove the car tridge 2 (fig. D3), taking care to avoid spilling the dust.
- Leave the safety car tridge in place.
- The following par ts 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 sur faces 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 car tridge (see: 3 - MAINTENANCE: FILTERS CARTRIDGES AND BELTS).
- Introduce the car tridge into the filter axis and push it in, pressing the edges and not the middle.
- Reassemble the cover, guiding the valve downwards.
