11.4 Oil Change
Oil should be drained directly after shutdown whilst the oil is still warm.
Caution
There is a
risk of burns
on the hot gearbox and a
risk of scalding
when
draining the oil!
Provide for suitable protection measures.
•
Unscrew the aeration and ventilation filter or remove the upper screw plug on one side of the housing.
•
If present, open the oil drain plug and collect the oil with a suitable container.
•
Fit drain plug with new copper seal and screw back into housing.
•
Fill the gearbox with oil.
•
Replace the oil filler plug or aeration and ventilation filter.
Note:
EvoGear gearboxes have
no
oil bore as standard. An oil change can only be carried out by trained
specialist personnel or by the manufacturer
.
Material Damage
Possible damage to the gearbox by inadequate lubrication due to incorrect or mixed
oils.
When carrying out an oil change always refill with the oil type previously used.
It is not permitted to mix different makes or mineral and synthetic oils, in particular
hydrocarbon oils must not be mixed with polyglycols. The mixtures may become
resinous or agglutinate and then precipitate into the gearbox.
11.5 Checking Gearbox Condition
This check may only be carried out by qualified operating personnel or by the Nidec Graessner Service
Department. Here, it must be possible to assess reliably what exactly needs to be replaced on the gearbox.
Or it must be determined that all gear components are in order.
