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 machine from the mains power.
3. Open the sanding drum cover (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 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 floor
to prevent it from turning while you are unscrewing the retaining nut.
