SCRUB DECK ADJUSTMENT
Scrub deck adjustment consists of three types of
adjustments. The first is to insure the individual
brushes make the same width pattern end to end.
Any tapered brush pattern should be adjusted out.
The second is to make the pattern of equal width
between front and rear brushes. Unequal patterns
are caused by the scrub deck not being parallel to
the floor. The third is to make the contact patterns
on the floor the correct width. Proper adjustment is
obtained when the contact patterns of the brushes
on the floor show two equal 1-1.5 inch (25-38 mm)
rectangles the width of the brushes. The rectangles
should be parallel to each other.
TESTING, ADJUSTMENT OF INDIVIDUAL
BRUSHES
1. Move the machine to an unfinished area of hard
floor to avoid marking carpet.
2. With pump off, lower scrub 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 scrub deck and note the brush
patterns on the floor. There should be two
rectangles with parallel sides. If the pattern is
tapered, proceed as follows.
ADJUSTMENT OF INDIVIDUAL BRUSHES
The brush pattern is adjusted from the motor side
only of both brushes.
1. Determine if motor end is to be moved up or
down to balance the pattern.
2. Loosen the 3 hex socket head screws on the
end of the housing.
3. Loosen the jam nut on the jackscrew and rotate
the jackscrew to move the motor assembly up or
down as needed.
4. Tighten the 3 hex socket head screws.
5. Tighten the jam nut on the jackscrew.
6. Re-test and readjust as necessary.
LEVELING THE SCRUB HEAD
Leveling the cylindrical head is accomplished by
adjusting the lower links that attach the deck to the
frame. Links should be adjusted to equal lengths. To
increase pattern width on rear brush, loosen lock
nuts and shorten the lower links by screwing the rod
into the threaded ends. To increase pattern width
on front brush, lengthen the lower links by screwing
the rod out of the threaded ends. After adjustment,
be sure to tighten lock nuts.
ADJUSTING BRUSH PRESSURE
Changing the brush pressure is accomplished by
adjusting the take-up nuts on the deck counter-
balance spring. To increase brush pressure or
pattern width, loosen the nuts. To decrease brush
pressure or pattern width, tighten the nuts.
