Changing the hydraulic oil and lters
Consult the summary Table at the start of this chapter to nd
out how often this must be done (pages D/9-10-11)
There are three mesh lters inside the tank (g.18/D Pos.“1”)
which avoid the issue of any dangerous particles in the
hydraulic system.
Replacement of the hydraulic oil, the lters inside the tank and
the hydrostatic lter must always be carried out in succession.
It is not possible to intervene on just one of the components.
To change the oil and lters correctly:
- Place the machine on level ground.
- Retract and lower the entire boom and position the cylin-
ders in transportation mode.
- Switch off the engine and remove the ignition key.
Place a “maintenance work in progress” sign in the cab.
- Place an adequately sized container below the drain plug.
- Remove the drain plug (g.18/D Pos.“2”) to drain the oil. Re-
move the ller cap (g.18/D Pos.“3”) to speed up the operation.
- When the tank is completely empty, remove the flange
(g.18/D Pos.“4”) by unscrewing the bolts and thus pro-
viding access inside.
- Unscrew the filters (fig.18/D Pos.“1”) inside the tank
using a fork spanner.
- Insert the new lters and tighten with the fork spanner.
- Reposition the flange (fig.18/D Pos.“4”) in its housing
and tighten the bolts.
- Reinsert the drain plug (g.18/D Pos.“2”).
- Fill the tank to the correct level through the filler cap
(g.18/D Pos.“3”).
- Start the machine and move the hydraulic cylinders to
release any air bubbles.
- Re-check the hydraulic oil level and top up if necessary.
- CAUTION:
Exhausted oil is a potential danger to the environment
and must be disposed of appropriately.
