7.3.4 Changing the oil
Stop!
¯ Secure the drive system and machinery against unintended movement
or mains power−up.
¯ The gearbox should be lukewarm in order that the oil flows well but
there is no risk of scalding.
¯ Only use lubricant types that match the nameplate or are listed in
Tab. 8.
1. Place receptacle under oil drain plug.
2. Remove breathing / oil filler plug.
3. Completely drain lubricant by removing the oil drain plug.
4. Reinsert drain plug (if necessary, replace seal).
5. Fill in lubricant through filler hole (quantities see nameplate).
6. Screw in breathing / oil filler plug.
7. Dispose of waste oil according to the applicable regulations.
Note!
Change from the CLP or CLP HC standard gearbox oil to the
food−compatible CLP xx xxx USDA H1 gearbox oil.
The oil drainage holes do not allow for complete draining of the gearbox
in all cases. Then a residual amount of oil remains in the gearbox. If a
change−over to a food−compatible gearbox oil is to be effected, the
gearbox must be rinsed thoroughly with the food−compatible gearbox oil.
