MAINTENANCE PROCEDURES
222
4.8.11 MAINTENANCE EVERY 1000 HOURS OF OPERATION
Carry out these operations together with those to be performed every 50, 250, 500 HOURS.
4.8.11.a CHANGING THE FRONT AXLE OIL
WARNING
q
Change the oil with the machine parked on a level surface
and the work equipment resting on the ground.
q
Oils, filters, the coolant and the battery are considered spe-
cial waste and must be collected and disposed of accord-
ing to the regulations in force.
CAUTION
q
On new machines change the front axle oil after the first
250 hours of operation and successively every 1000 hours.
This operation must be carried out with the machine positioned on
level ground and at operating temperature, so that the oil be-
comes fluid and can easily be drained, which facilitates the elimi-
nation of any suspended solid particles.
DIFFERENTIAL
1 - Remove the drain plug (2) and let the used oil flow out com-
pletely, gathering it into a container with suitable capacity.
While the oil flows out, remove the plug (1).
Use a 17 mm wrench.
2 - Once the oil has been drained, put back the drain plug (2)
and add oil of the prescribed type through the hole (1), until
reaching the level corresponding to the lower edge of the
hole itself.
3 - Put back the plug (1).
FINAL REDUCTION GEARS
1 - Move the machine until the plug (3) is in low position on the
vertical axis.
2 - Remove the plug (3) and let the used oil flow out, gathering it

3 - Once the oil has been drained, move the machine until the
plug (3), which serves also as level indicator, is positioned on
the horizontal axis.
4 - Add oil of the prescribed type until reaching the lower edge of
the hole itself.

Carry out some forward and backward movements, stop the ma-
chine and check the levels again. Always use oil of the prescribed
