All drum motors are factory filled with oil that is free of detergent additives .
NOTE:
Do not use oil additives which can cause damage to the motor
insulation or seals . Electrically conductive-bases oils, such as graphite and
molybdenum disulfide, should not be used, as they will result in electric
motor insulation damage .
OIL CHANGE
1 . Allow the drum motor to cool to normal temperature .
2 . Rotate the drum motor until the oil plug is located in the 6 o’clock position .
3 . Unscrew the oil plug and allow the oil
to drain completely .
Note:
There may be internal pressure
released when removing the oil plug,
this is normal .
4 . Refill the drum motor with the suggested
oil type (page 11) and amount of oil
(pages 12-13) .
To verify the oil level, rotate the drum motor until the oil plug is in the
4 o’clock position as shown in the diagram . The minimum oil level
should be up to the level of the oil plug .
For exact oil quantities consult VDG
(Van der Graaf) Technical Support* .
Note:
typical levels are higher but should
not exceed the level where the oil plug
is in the 3
o’clock position .
5 . Re-install the oil plug and if available,
install a new copper seal .
