Machine Controls and Features

Squeegee Lift Handle,  See Figures 5

The squeegee lift handle is located below the control

handles in the center.  It is used to raise or lower the

squeegee.  The vac motor is turned on when the

handle is lowered to either the first or last position.

NOTE: Squeegee must be raised to at least the

first position when the machine is backed up.

Float Shut Off, See Figure 6

The shut-off switch for the vac motor is located in the

recovery tank.  It automatically turns off the vac motor

when the recovery tank is full.  

NOTE: If excessive

foaming in recovery tank, defoamer must be

added.  Damage to vacuum motor could result

from foam.

Parking Brake, See Figures 7a and 7b (Optional)

The parking brake prevents movement of the machine.

It is located at the rear lower left side of the machine.

To engage the brake, push the pedal down (Figure 7a).

To release the brake, lift pedal up (Figure 7b).

CAUTION: Do not activate the brake while the

machine is moving.
