CHECKING CYLINDRICAL BRUSH PATTERN
1. Apply chalk, or a similar marking material, to
a smooth and level section of the floor.
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.
2. Raise the scrub head, then position the
brushes over the chalked area.
3. Block the front or rear wheels to prevent the
machine from moving.
4. Lower the scrub head in the chalked area and
slowly press the propel pedal until the scrub
brushes start spinning. Allow the machine to
scrub in the same place for 15 to 20 seconds.
5. Raise the scrub head and drive the machine
away from the chalked area.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
6. Observe the brush patterns. If the brush
pattern is the same width across the entire
length of each brush and both brushes are the
same width, no adjustment is necessary.
