CHECKING AND ADJUSTING MAIN BRUSH
PATTERN
1. Apply chalk, or some other material that will
not blow away easily, to a smooth, level
floor.
2. Raise the side brush and main brush and
position the main brush over the chalked
area.
3. Start and lower the main brush for 15 to 20
seconds while keeping a foot on the brakes
to keep the machine from moving.
NOTE: If chalk or other material is not available,
allow the brushes to spin on the floor for two
minutes. A polish mark will remain on the floor.
4. Raise the main brush.
5. Drive the machine off the test area.
6. Observe the width of the brush pattern. The
proper brush pattern width is 50 to 75 mm
(2 to 3 in).
The brush taper is factory set and should not
need adjustment unless parts of the brush
system have been replaced.
