TAPERED MAIN BRUSH PATTERN
A. Main Brush Pattern
If the main brush pattern is tapered, more than 0.5 in
(15 mm) on one end than the other, on a flat, level
surface, first loosen the main brush left cross shaft
bearing mounting brackets and the bearing flanges.
Then pivot the bearing mounting bracket to level the
cross shaft. Tighten the bearing mounting bracket
and the bearing flanges. Check the main brush
pattern and readjust as necessary. Then adjust the
width of the main brush pattern.
To widen the main brush pattern, loosen the locking
wing nut and turn the adjustment knob
counterclockwise from the top. To reduce the width
of the main brush pattern, loosen the locking wing
nut and turn the adjustment knob clockwise from the
top.
Tighten the locking wing nut and recheck the main
brush pattern. Repeat the procedure until the main
brush pattern is within the specified range.

SIDE BRUSH
The side brush sweeps debris from curbs or gutters
into the path of the main brush. It should be
inspected daily for wear or damage. Remove any
string or wire found tangled on the side brush or side
brush drive hub.
The side brush pattern should be checked daily.
Between one-third and one-half of the side brush
bristles should contact the floor when the brush is in
motion. The side brush pattern adjustment on low
dump model machines is made by loosening the two
nuts on the side brush arm, repositioning the side
brush assembly, and retightening the nuts.
The side brush should be replaced when the
remaining brush bristle measures 2.5 in (65 mm) in
length.
