BRUSH DECK ADJUSTMENT
Brush deck adjustment consists of one adjustment
to make the pattern of equal width between front and
rear brushes. Unequal patterns are caused by the
deck not being parallel to the floor. Proper
adjustment is obtained when the contact patterns of
the brushes on the floor show two rectangles the
width of the brushes. The rectangles should be
parallel to each other.
TESTING, ADJUSTMENT DECK LEVELNESS
1. Move the machine to an area of hard floor to
avoid damaging carpet.
2. Lower brush head to floor. Allow brushes to run
for approximately 30 seconds. It may be
necessary to repeat this step in the same
location until a good mark can be seen on the
floor. This can be accomplished by touching
lightly the throttle pedal to restart the scrub deck
without moving the machine.
3. Raise the brush deck and note the brush
patterns on the floor. There should be two
rectangles with parallel sides. The width of the
front and rear rectangle should be equal.

LEVELING THE BRUSH HEAD
Leveling the brush head is accomplished by
adjusting the lower links at the point the deck arms
attach to the frame. To increase pattern width on
rear brush, loosen the mounting hardware and slide
that joint forward and retighten.
To increase pattern width on the front brush, loosen
the mounting hardware and slide that joint rearward
and retighten.
Retest for levelness.
