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.
