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.

SQUEEGEE BLADES
The scrub head has 2 sets of 2 squeegee blades on the front and back. These blades squeegee up the solution off the floor in the forward and reverse directions. The front and rear squeegee blades (with the many corrugations) should be checked for damage and wear daily. When the inside wiping edge of the front and rear (corrugated) blades become rounded or have tears in them, they will not pick up solution properly. Replace any worn or damaged squeegee blades. The inside squeegee blades (the ones with the slots) normally only need to be checked monthly.
REPLACING SQUEEGEE BLADES:

STORING MACHINE
Freeze protection of the machine is necessary to prevent damage to components of the solution system when the machine is going to be exposed to freezing temperatures.
ATTENTION: Freezing temperatures can severely damage components. Do not store or transport machine in areas where freezing of solution contents could occur, unless machine is freeze protected. Failure of components due to lack of freeze protection voids the warranty on such components.
FREEZE PROTECTION
1.
Pour 3.8 L (1 gal) of pre-mixed automotive-type windshield washer solution into solution tank.
ATTENTION: Do not use cooling system anti-freeze such as ethylene glycol.
2.
Move machine over floor drain and plug the power cord into an outlet.

3.
Set the MODE switch in the WAND position. The pump will start and spray through the feed tube to the floor. Run in this manner until all of the solution is dispensed.
4.
Repeat the same process for any wand attachments that may freeze by attaching wand to the machine and opening the hand valve until all solution is dispensed.
ATTENTION: Machines and attachments that have been freeze protected must be flushed completely prior to normal use. Follow directions for the appropriate cleaning process, but run your selected cleaning solution through the system to purge all anti-freeze before starting the cleaning process.
