D5 - HYDRAULIC RETURN OIL FILTER CARTRIDGE
CHANGE
Stop the I.C. engine and remove the pressure from the circuits by acting on the hydraulic
controls.
Thoroughly clean the outside of the filter and its surroundings before any intervention in
order to prevent any risk of polluting the hydraulic circuit.
- Open the side bonnet.
- Remove cap 1 (fig. D5/1) andunscrew the cover 2 (fig. D5/1) two or three turns
- Wait a few moments while the oil flows into the tank.
- Remove the cover and take out the filter cartridge assembly 3 (fig. D5/2).
- Place the assembly in a clean container and empty the bowl.
- Remove the bowl 4 and the top 5 of the filter cartridge 6 (fig. D5/3) by a movement of
rotation.
- Refit the bowl and the top onto a new cartridge (see: 3 - MAINTENANCE: FILTER
ELEMENTS AND BELTS).
- Fit the assembly in place and retighten the cover 2 (fig D5/1).
- Put the cap back 1 (fig. D5/1).
D6 - BALANCING VALVE
CHECK
To be performed after the first 50 hours of operation and then every 500 hours.
Stop the lift truck on horizontal ground, put the handbrake on and set the reverse gear to neutral.
ROLE OF BALANCING VALVES
- The balancing valves protect the user from any risk due to a fall in hydraulic pressure or an exploding hose during hydraulic
operations.
Keep everyone well away during these inspections.
In all cases, the balancing valve(s) concerned must be repaired or replaced if hydraulic movement continues after the I.C. engine has
been switched off.
Never use the lift truck with a defective balancing valve.
TESTING EACH HYDRAULIC MOVEMENT
LIFTING CIRCUIT:
- Start up the lift truck and raise the jib by about 45°.
- With the I.C. engine running at mid- speed, lower the jib. While the jib is being lowered, switch off the I.C. engine; movement
should slow down as the I.C. engine speed falls and stop when the I.C. engine stops.
