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 gear unit, and a
risk of scalding
when draining
the oil!
Provide for suitable protection measures!
▪
Unscrew the ventilation filter or remove the upper screw plug on one side of the housing,
open the oil drain plug and collect the oil in a suitable container.
▪
Equip the drain plug with a new copper seal and screw it back into the housing.
▪
Fill gear unit with oil, see also section 8.
▪
Reinsert oil filler plug or breather filter.
Material damage
Possible damage to the gear unit due to insufficient lubrication caused by
incorrect or mixed oils.
When changing the oil, always refill with the same oil type previously used!
It is not permitted to mix different makes or mineral and synthetic oils.
Specifically, hydrocarbon oils must not be mixed with polyglycols.
The mixtures may be resinous or clump together and settle in the gear unit.
11.5 Checking the gear unit condition
This check may only be carried out by qualified operating personnel or by the service department of Nidec
Graessner. It must be possible to reliably assess what needs to be replaced on the gear unit or to determine
that all gear unit parts are in good order.
