Replacement Instructions

10. Looking at the aforementioned video if necessary, take the new belt(s) and place them over the
appropriate pulley(s). Remember – the thinner belt goes over the lower pulley. Make sure that the
lower belt also runs along the idler pulley, so as to keep proper tension on the belt.
Fig. 10. The idler pulley. The belt for the lower pulley should run with its flat surface against the inside
surface of this pulley (to the left of the pulley, as shown in this photo).
11. Re-assemble the sander, following steps 9 – 1 in reverse order. Some tips:
• Ensure that the belts are level with the pulleys on the primary drive gear (yellow arrow, Fig. 10
above).
• Do not forget to plug in the brown wires, as in Fig. 3 above. Refer also to Fig. 11 below.
• Run the sander for a few moments without any spindle drum or sandpaper on it, to make sure
that the new belt(s) get seated properly around the pulleys, and that the oscillating motion works
properly.
