Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Warning
Thrown debris has considerable force and could
cause injury.
• Stay away from the sweeping area when the
machine is operating.
• Keep bystanders away from the sweeping area
when the machine is running.
Operation
1. Lower the brush to the ground ensuring the lift circuit is
in the float position. The float position is engaged by
moving the center lift lever forward and releasing it to
return to the neutral position.
2. Increase engine speed to full throttle position.
3. Engage PTO switch.
4. Drive traction unit at a slow, comfortable speed.
Operating Tips
You can add measurable sweeping hours to your brush by
remembering these simple things:
1. More pressure doesn't give a better sweep.
2. A level brush lasts longer.
3. Faster ground speed will cause the brush to wear faster.
Adjust Brush Down Pressure
Improper downward pressure can decrease brush life up to
95% (depending on the incorrect amount of pressure).
A brush sweeps with the tips of its bristles. When too much
down pressure is applied, the brush is no longer using it's
tips; the brush is now working with the sides of the bristles.
This limits the flicking action of the bristles and limits it's
sweeping effectiveness.
To check for correct downward pressure, operate brush on
the ground, rotating at normal operating speed with traction
unit remaining stationary. Stop operation, raise brush and
measure width of swept path. A properly adjusted brush
will have a sweeping path width of 2"–4".
Adjust castor height for proper brush ground pressure. The
castor wheel height is adjustable from 4 to 7 inches in 1/2
inch increments by adding or removing an equal amount of
spacers from each castor wheel.
1. Start engine and raise brush. Stop engine after brush is
raised.
2. Remove cap securing castor spindle to frame bracket.

3. Move desired amount of spacers to top or bottom of
bracket. Make sure spacers are equal on both castor
wheels and a thrust washer is positioned on each side of
frame bracket.
4. Install cap and lower brush.
Ground Speed
Bulldozing produces a side thrust and excessive stress on
the brush, core and frame. While operating under the plow
effect, the bristles are flexed against the steel ring which
holds them and, eventually, this flexing will break the
bristles from the ring.
If ground speed is too fast, debris will pile up in front of
brush causing brush to bulldoze instead of sweep. This can
damage not only the brush, but also the core, chains,
sprockets, drive lines and frame.
Switch Operation
One switch will rotate the brush to the right and the other
switch will rotate the brush to the left. The brush must be
on the ground and rotating to change the angle of operation.
