CHECKING AND ADJUSTING MAIN SWEEP
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 sweep brush
and position the main sweep brush over the
chalked area.
3. Start the main sweep brush.
4. Lower the main sweep brush for 15 to 20
seconds while keeping a foot on the brakes
to keep the machine from moving. This will
lower the rotating main sweep brush.
NOTE: If chalk or other material is not available,
allow the sweep brush to spin on the floor for two
minutes. A polish mark will remain on the floor.
5. Raise the main sweep brush.
6. Stop the main sweep brush.
7. Drive the machine off the test area.
8. Observe the width of the brush pattern. The
proper brush pattern width is 50 to 65 mm
(2.0 to 2.5 in).
9. To increase the width of the main sweep
brush pattern, turn the main sweep brush
down pressure knob counter-clockwise.
To decrease the width of the main sweep
brush pattern, turn the main sweep brush
down pressure knob clockwise.
