DOWN PRESSURE KNOB SETTINGS
A. Main Brush Pressure Knob
B. Lock Nut
To reduce brush down pressure, which raises the
brush, loosen the lock nut and turn the knob
clockwise. Hand tighten the lock nut. Be aware the
lock nut is left---hand threaded. Do not use a
wrench to tighten nut.
Use the colored bands on the center stem for a
reference point when you want to repeat a down
pressure setting.
SIDE BRUSH LEVER
The side brush lever operates the side brush control
valve which controls the side brush motor.
Pushing the control lever out starts the side brush
rotating, provided that the main brush is also
operating.
Pulling the control lever back stops the side brush
rotation.
NOTE: The side brush will not operate unless the
main brush is also operating.
HOPPER DOOR LEVER
The hopper door lever controls the hopper door
position.
Pushing the control lever away from the operator into
the “open” position, opens the hopper door into the
“operating” position.
Pulling the control lever back into the “close”
position, closes the hopper door so the hopper may
be raised without allowing the debris in the hopper to
spill.
Always sweep with the hopper door in the “open”
position.
VACUUM FAN AND HOPPER LIFT LEVER
The vacuum fan and hopper lift lever controls
vacuum fan and the hopper position.
Pushing the lever down into the “vacuum on”
position starts the vacuum fan.
Pulling the lever up slightly into the “raise” position,
raises the hopper.
Pulling the lever all of the way into the “hold” position
stops the hopper from further raising or lowering.
The center lever position allows the hopper to lower.
WARNING: Always engage the hopper
support bar before working under a raised
hopper. Do not rely on the machine hydraulic
system to keep the hopper in the “raised”
position. The hydraulic system may leak
internally, allowing the hopper to lower, crushing
anything under it.
