Description: After changing the sandpaper, the device...

Steps:

1. Make sure that the device is disconnected from the power supply. (i.e., the power plug is not plugged into the power outlet)
2. Remove sandpaper holder (green)
3. Remove all 10 screws (red) using a PH2 screwdriver

4. Remove blue plastic housing.

5. Push the orange slider upwards to remove it
6. Lift the switch

7. Pull off the plug contacts of the switch. This can be pretty tough. A pair of needle-nose pliers can help.

8. Toggle the switch several times, then blow it out. Ideally, use a pressurized air gun, but blowing on it may also work.
9. If possible, use a multimeter to test whether the switch is working reliably again.
10. If necessary, install a new switch. Unfortunately, we do not currently know of any suppliers.

11. Make sure that the switch is installed correctly. “1” is facing away from the operator. Observe this for both the black switch and the orange slider.
12. Make that no strands are pinched and that the sliding contacts (green) are positioned correctly in the holders.
