CHECKING AND ADJUSTING MAIN BRUSH

PATTERN

1. Apply chalk (or another material that will not

easily blow away), to a smooth, level section

of the floor.

2. Lower the main brush in the chalked area.

Allow the machine to sweep in the same

place for 15 to 20 seconds.

NOTE: If chalk or other material is not available,

allow the brush to spin on the floor for two

minutes. A polish mark will remain on the floor.

3. Raise the main brush and move the machine

away from the chalked area. Turn the

machine power off.

4. Observe the shape of the brush pattern. If

the brush pattern has parallel sides, the

brush does not need adjustment.

If the brush pattern is tapered, the main

brush needs adjustment to straighten the

brush pattern.

A. To adjust brush taper, loosen the nut at

the left end of the brush arm crossbar.

Move the crossbar up or down in the

slide relative to the adjustment on the

other side. Tighten the nut.

B. Check the brush again pattern and

readjust if necessary.
