Checking the Scrub Brush Pattern
For the best results perform the scrub brush pattern tests on
a smooth even fl oor.
Note:
Chalk or chalk powder applied to the fl oor will help to
show the brush pattern. If chalk is not available allow the
brushes to turn on the fl oor for 1 or 2 minutes. A polished
brush pattern will be visible on the fl oor.
1. Raise the scrub deck.
2. Position the scrub deck over the chalked area.
3. Set the parking brake.
For Safety:
Before leaving machine, turn off the machine,
set the parking brake, and remove the key.
4. Lower the scrub head for 10-15 seconds. Do not allow
the machine to move forward or backward.
5. Raise the scrub deck.
6. Release the parking brake and drive the machine away
from the chalked area.
7. Check the width and shape of the brush patterns on the
fl oor. If the long edges of the two brush patterns are
parallel then a brush pattern adjustment is not required.
If only one of the scrub brush patterns is tapered then
only that brush pattern must be adjusted. If both of the
brush patterns are tapered then both brush patterns must
be adjusted.
