4.7.10 MAINTENANCE EVERY 1000 HOURS OF OPERATION
4.7.10.a CHANGING THE OIL IN THE TRAVEL REDUCTION GEARS
These operations must be carried out together with those to be carried out every 100, 250, 500 HOURS.
DANGER
•
Soon after the machine has been stopped the engine oil is very hot; let the engine cool down until it
reaches a temperature of 40÷45°C before changing the oil.
•
Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
posed of according to the anti-pollution regulations in force.
This operation must be carried out with the machine on level
ground at a temperature of 40÷45°C, so that the oil is more fluid
and can be drained easily together with the suspended solid par-
ticles.
1 - Move the machine until the drain plug (1) is in low position
and aligned with the level plug (2) on the vertical axis.
2 - Remove the drain plug (1) and let the used oil flow out com-
pletely, gathering it into a container with suitable capacity.
While the oil flows out, remove the level plug (2).
Use a 8 mm setscrew spanner.
3 - After draining the oil, put back the plug (1) and pour new oil of
the prescribed type through the hole (2) until reaching the
lower edge of the hole itself.
4 - Put back the plug (2).
Carry out some movements, stop the machine and check the
levels again.
Use only the prescribed oil.
