MODE SWITCH

The mode switch controls various scrubbing
functions.

For normal scrub operation, place the mode
switch in the BRUSH AND WATER (TOP)
position. In this position, both brush and solution
pump will operate when either brush/solution lever
is activated. Both functions will stop when the
lever(s) are released.

For double scrub operation, place the mode
switch in the BRUSH ONLY (CENTER) position.
When the lever(s) are activated, only the brush
will operate; solution will not flow.

For attachment option use, place the mode switch
in the WAND (BOTTOM) position. Only the
solution pump will operate in this position.

NOTE: Make sure solution dispensing tube is
disconnected from the female quick disconnect, or
the option is attached to female quick disconnect,
otherwise solution will immediately begin to flow
onto the floor until the tank is emptied.

VACUUM FAN SWITCH

The vacuum fan switch controls the vacuum fan.
Press the bottom (I) of the switch to turn on the
vacuum fan. Press the top (

O

) of the switch to

turn off the vacuum fan.

BRUSH/SOLUTION LEVER(S)

The machine has two levers under the machine
handles at the top of the control panel. The
brush/solution lever(s) turn on the scrub brush
and the solution pump. One or both of the levers
can be used to start the scrub brush and solution
pump when the MODE switch is in the BRUSH
AND WATER position. Only the brush will run
when the lever(s) are operated if the MODE
switch is in the BRUSH ONLY position. In the
WAND position, neither the brush nor solution
pump are activated by the lever(s).

BRUSH PRESSURE GAUGE

The brush pressure gauge indicates the pressure
of the scrub brush on the floor. The brush
pressure needle should be at the top of the green
zone for the best scrubbing results.

BRUSH CIRCUIT BREAKER

The brush circuit breaker protects the brush motor
from overload. If the brush pressure is too high,
the brush circuit breaker will trip and the scrub
brush will stop. To reset the brush circuit breaker,
press the circuit breaker reset button on the circuit
breaker. It may be necessary to allow the circuit
breaker to cool down before resetting, or it may
trip again. Reduce the brush pressure before
resuming scrubbing and check the brush for
obstructions.

SCRUB HEAD LIFT LEVER

The scrub head lift lever raises the scrub head off
the floor. Raise the scrub head with the scrub
head lift lever when transporting  the machine
from place to place, and when the machine is not
being used.  To raise the scrub head, step on the
scrub head lift lever. To lower the scrub head, pull
the lever up with the toe of your shoe.

BRUSH DOWN PRESSURE KNOB

The brush down pressure knob adjusts the
pressure of the scrub brush against the floor. The
brush down pressure knob is located on the
underside of the scrub head lift lever. To increase
the scrub brush pressure, turn the pressure knob
to the left. To decrease the scrub brush pressure,
turn the knob to the right.

DOUBLE SCRUB LATCH

The double scrub latch locks the squeegees up.
The lever is located on the front of the scrub. Pull
up on the lever and hook it onto the frame above
the scrub head.
