Adjusting the Scrub Brush Pattern (Taper)
The front scrub brush pattern adjustment is located behind
the right side scrub brush door.
The rear scrub brush pattern adjustment is located behind
the left side scrub brush door.
1. Raise the scrub brush side door.
2. Release the retaining latch at the rear of the side
squeegee mount and swing the side squeegee mount
open.
3. Loosen the four pattern adjustment nuts located on either
side of the scrub brush idler plate.
4. Raise or lower the scrub brush idler plate as necessary
to correct the tapered brush pattern. Raising the idler
plate will decrease the brush pattern width on that side of
the scrub deck.
Note:
Lowering the idler plate will increase the brush pattern
width on that side of the scrub deck.
5. Tighten the four pattern adjustment nuts.
6. Close and latch the side squeegee mount. The side
squeegee mount holds the brush idler plate in place.
7. Check the scrub brush pattern again and readjust if
necessary.
The brush patterns should also be the same width. If one is
wider than the other then the scrub brush pattern width must
be adjusted.
