TO CHECK AND ADJUST WIRE BRUSH PATTERN
1. Place the brush power lift lever in the “down”
position.
2. Stop the engine and engage the machine
parking brake.
WARNING: Always stop the machine on a
level surface, stop the engine and engage
the parking brake before working on the machine
to keep it from rolling.
3. Place the main brush lever in the “restricted
down” position.
4. Open the right side brush access door.
5. With the brush resting on the floor, adjust the
main brush height adjustment knob so the
brush just touches the pin in the brush lift bell
crank. Tighten the lock nut on the adjustment
knob.
NOTE: As the brush wears, the adjustment knob will
have to be adjusted to apply proper brush pressure
to the floor. Be sure to use the hydraulic pressure
gauge. It should read between 1800 and 2200 psi
(12,410 and 15,510 kPa).
SIDE BRUSH
The side brush 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 should be replaced when the
remaining brush bristle measures 2.5 in (65 mm) in
length.
The side brush has four adjustments. The only
adjustment which requires regular attention
compensates for side brush wear. It is controlled by
the side brush height adjustment knob and cable.
To adjust the lowered height, place the side brush in
the “lowered” position. Loosen the side brush knob.
Slide it forward to lower the side brush, or slide it
backward to raise the side brush. Tighten the knob
after the desired height is reached.

replacing any major component of the side brush lift
mechanism and after readjusting the hopper.

3. Remove the side brush retaining bolt from the
side brush hub and shaft.
