6.3 LUBRICANTS
Before putting the gear unit into service, check the oil level. This must be done with the gear unit in the
mounting position in which it will be used in the application. If necessary, if or top up the lubricant to
the filling mark on the level cap which may be transparent or of the spill type.
The lubricant utilised must be new and uncontaminated and can be poured in through the filler hole or
from the inspection cover opening using a filler filter with 25 µ
m mesh, ensuring that the relative gasket
is refitted without damaging it or reapplying the sealant to provide a perfectly oil-tight fit.
The oil level must never be below the minimum notch and must be checked periodically
with the gear unit at a standstill after allowing it to cool for a short period.
Do not mix oils of different nature or specifications and check that the oil is highly
resistant to foaming and is EP rated.
In the case of gear units equipped with forced lubrication, the oil circuit must also be filled. In this case
the unit must be run for a short period and then stopped before rechecking the oil level.
If the same type of oil as that already in use is not available, drain the gear unit completely and flush its
interior thoroughly with a light solvent before refilling with a new lubricant.
