D3 - DRY AIR FILTER CARTRIDGE
CHANGE
In case of use in a heavily dust laden atmosphere, there are pre-filtration cartridges, see: 3 -
MAINTENANCE: FILTERS CARTRIDGES AND BELTS. Also, the checking and cleaning periodicity
of the cartridge 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 cartridge 2 (fig. D3), 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: 3 - MAINTENANCE: FILTERS CARTRIDGES AND BELTS).
- Introduce the cartridge into the filter axis and push it in, pressing the edges and not the middle.
- Reassemble the cover, guiding the valve downwards.
D4 - FUEL PRE-FILTER
CHANGE
Make sure the electrical contact on the lift truck is cut, otherwise fuel will be released if the lift pump is on.
- Open the I.C. engine bonnet.
- Carefully clean the outside of the pre-filter and its holder, to prevent dust from getting into the
system.
- Place a container under the pre-filter and drain it using drain plug 1 (fig. D4).
- Remove bleeder screw 2 (fig. D4) in order to ensure that the oil is drained properly.
- Unscrew locking screw 3 (fig. D4).
- Remove housing 4 (fig. D4) and discard pre-filter 5 (fig. D4) and its seals.
- Clean the inside of the pre-filter head and the housing, using a brush immersed in clean diesel
oil.
- Refit the assembly with a new pre-filter and new seals (see: 3 - MAINTENANCE: FILTERS
CARTRIDGES AND BELTS).
- If necessary, bleed the fuel circuit (see: 3 - MAINTENANCE: G1 - FUEL SYSTEM).
