BRUSH DRIVE SYSTEM
BRUSH ASSIST STRENGTH
First adjust the brush deck pressure to assure it is operating in the green area. Next,
adjust the propulsion strength on a flat level part of the surface you are scrubbing. With
the brush motor off, the brush head down and with the scrub brush or pad driver/pad
combination you will be using adjust the propulsion strength. Test the amount of propul-
sion and readjust as necessary making sure to keep the brush pressure in the green area,
Be careful that you do not set the propulsion level too high or the machine may become
uncontrollable and unsafe or not perform acceptably.
INSTALLING & REMOVING BRUSHES
Raise the brush deck as high as it will go with
the brush deck switch. Turn machine power off.
Loosen the two knobs at the front of the scrub
deck and slide the shroud off the deck. Rotate
the brush until both tabs of the spring clip are ac-
cessible. Squeeze the two tabs together and the
brush will drop off.
To install a brush reverse the procedure.
SETTING BRUSH PRESSURE
Lower the scrub deck to the floor. Turn on the solution
switch and turn on the brush by using the green handle-
bar button. Observe the brush pressure gauge on the
control panel and make sure it does not enter the red
zone while scrubbing. If the machine is operated in the
red zone, the motor is being over-worked, and it will
blow the brush circuit breaker. If this breaker blows,
wait until it cools and reset it. Reduce brush pressure
and resume scrubbing.
