- CLEANING THE AIR FILTER CARTRIDGE
Slacken nut 1(Fig. B1/1) and remove cover 2 (Fig. B1/1).
Slacken nut 3 (Fig. B1/2) which fixes cartridge 4 (Fig. B1/2).
Clean the filter cartridge using a jet of compressed air directed from insi-
de outwards.
Clean the inside of the filter housing using a clean, damp cloth that does
not leave residue, protecting the inlet tube to the I.C. engine. Check the
condition of the cartridge.
Cartridges that are no longer efficient must be replaced immediately.
Refit cartridge 4 (Fig. B1/2) inside the filter and fix it by means of nut 3
(Fig. B1/2).
Refit cover 2 (Fig. B1/1) with the valve facing downwards and lock it by
means of nut 1 (Fig. B1/1).
Never wash an air filter cartridge.
- CHECK THE HYDRAULIC OIL LEVEL.
Place the truck on a flat surface with the engine off and the telescopic
boom retracted and as low as possible.
Refer to the gauge “1” (fig. B2/1).
The oil level is correct when it is 3/8 in. under the maximum of the upper
and lower marks.
If necessary, top up with oil (see “OILS - GREASES -
FLUIDS - FUEL - FILTERS” table) through the filler hole “2” (fig. B2/2).
The oil must always be kept topped up to the maximum level, since cool-
ing improves as the oil passes through the tank.
- CLEAN THE OIL/WATER RADIATOR GRILLE
To prevent the radiator from clogging (water radiator fig. B3/1 ; oil radiator
fig. B3/2), it must be cleaned with a jet of compressed air from the inside
towards the outside.
This is the only way to clean off the debris.
