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 of f.
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.
