8.0 Maintenance
8.1
Changing the sanding drum
If the sanding drum is damaged or worn, it must be replaced.
Instructions:
1. Turn the machine off.
2. Disconnect the main power from motor.
3. Open the access door (1).
4. Fold the tension lever (2) forward to relieve the tension on the sanding belt.
5. Remove the sanding belt (3) to the side.
6. Unscrew the retaining nut (4):
The retaining nut is glued to the threads of the sanding drum shaft to ensure that it
will not fall off while the COBRA II is in operation. To unscrew the retaining nut, use
the double fork wrench that comes with the machine. Lower the sanding drum so
it has contact with the fl oor to prevent it from turning while you are unscrewing the
retaining nut.
