Changing the Drive Belts

Depending on usage, the drive belts, (located behind the side plate), will stretch. When this happens, in order to maintain the optimum performance of the unit, these drive belts have to be changed.

2.Inside, locate four screws on drive motor side which hold the side plate in place, see Figure 15.

3.Take out these four screws and remove the side plate, see Figure 16.

4.Remove the drive track. Before removing the drive track, notice how the drive belts are positioned for re-assembly, see Figure 17.

5.Take out the old drive belts and replace them with new ones (P/N P12111). To re-assemble, reverse Steps 4 to 1 above.

Changing Brushes

It is necessary to replace the brushes when they are worn out, (when the brushes reach the plastic of the wheel). Worn out brushes will impede the cleaner’s scrubbing, climbing the walls and/or general performance.
