MACHINE OPERATION
WARNING !
Do not operate machine unless you have read and understand this manual.
Before the machine will operate, the key switch must be turned into the “on” position. The key is located on the left side of the control housing.1.
(see machine components, item #19)
Set control housing to a comfortable operating height by squeezing together the tow thumb levers directly underneath the housing (see2.
machine components item #16)
Lower squeegee assembly to the floor. There is a squeegee lift handle located on the back left of the machine, just under the control housing.3.
(see machine components, item #14) Slightly lift up on the handle and move it to the right, the squeegee is now ready to be lowered to the
floor.
Lower the brush head to the floor by pushing the brush lower button on the control housing. (see machine components, item #7)4.
Turn vacuum motor switch to “on” position. (see machine components, item #1)5.
Turn the brush motor switch to “on” position. (see machine components, item #2)6.
Brushes will not spin until the operating triggers are pulled.a.
Turn the solution switch to “on” position. (see machine components, item #3)7.
Solution will not begin to flow until the operating triggers are pulled.a.
To begin scrubbing, pull on one or both of the red operating triggers. (see machine components, item #27) When the triggers are pulled, the8.
brushes will begin to spin, the solution will begin to flow, and the machine will propel itself.
This machine is self-propelled. The speed can be adjusted by a dial located on the right side of the control housing. (see machine9.
components, item #9)
This machine has reverse. In order to activate reverse, there is a toggle switch on the left side of the control housing. (see machine10.
components, item #20) The toggle switch must be pulled / pressed to activate reverse motion.
HINT: Do not keep the machine in the same position with the pad / brush spinning, or you could cause damage to the floor.
Adjust the amount of solution flow by turning the solution control knob. Turn the knob to the right for more solution, or turn left for less11.

WHILE OPERATING MACHINE
Occasionally look through the clear recovery tank lid to see if there is any foam build-up. If excessive foam is found, add defoamer to the1.
recovery tank.
WARNING !
Foam must not enter the float shutoff screen, or damage can occur to the vacuum motor. Foam will not activate the machines float
shut-off device.
Occasionally view the clear tube at the back left of the machine to check the amount of cleaning solution that is left in the machine.2.
Occasionally check the battery level meter. (see machine components, item #3) When the meter is in the red, recharge the batteries.3.
WARNING !
When battery meter is in the red, do not continue to operate the machine. Battery damage may occur.
4. If the squeegee assembly leaves streaks on the floor, raise the squeegee off the floor and wipe the blades down with a damp cloth.
WARNING !
Do not use your fingers to wipe or remove debris from the blades, as injury may occur.
5. When the solution tank runs empty, turn off the brush switch, solution switch, and raise the brush head. Keep the squeegee down and continue
to vacuum until all the dirty water is picked up. (see TANK DRAINING section to learn how to drain recovery and solution tanks)
HINT: The brush motors are circuit breaker protected to protect them from damage. If a breaker trips, it can’t be reset immediately.
You must first determine what caused the breaker to trip, and allow the motor to cool down before you can reset the breaker. The
breakers are located on the rear panel of the control housing.
TANK DRAINING
Turn the power off on the machine1.
With the squeegee and brush head in their “up” position, transport the machine to an approved area for draining the tank(s).2.
DRAINING THE RECOVERY (DIRTY) TANK
HINT: Anytime scrubbing is completed, or when refilling the solution tank, the recovery tank should also be drained and cleaned.
WARNING !
If the recovery tank is not drained when the solution tank has been refilled, foam or water may enter the float shut-off mechanism and
cause damage to the vacuum motor.
Remove the drain hose from the holder and place the drain hose over a floor drain. Twist off the drain hose plug to begin the draining process.1.
In order to completely empty the recovery tank, hinge open the recovery tank and let it rest on the support stand.
Clean the recovery tank after every use. Use a fresh water hose to rinse out the inside of the tank. Be careful not to spray water into the float2.
shut- off mechanism.
HINT: If you are storing the machine for any period of time, always leave the clear recovery tank lid off the tank so the tank may dry
completely, and smell fresh.
Replace the drain hose plug tightly as soon as you are done draining the tank.3.
DRAINING THE SOLUTION (CLEAN) TANK
HINT: Anytime scrubbing operation is completed, the solution tank should be drained and cleaned.
Pull down on the clear tube (back left of the machine) to remove it from the hose barb. This will allow the solution to flow freely into a bucket1.
or floor drain.
Rinse the solution tank with clean water after every use. This will help prevent chemical buildup and clogging of the solution lines.2.
With clean water in the solution tank, turn machine power on, solution switch “on” and pull the operating triggers. This will allow the clean3.
water to flush through and clean the solution plumbing.
Once the tank is rinsed, flushed and drained, reconnect the clear tube to the hose barb. Be sure the tube is pushed all the way up on the hose4.

Overfilling may cause the batteries to overflow during charging due to expansion. Replace the caps prior to charging.
Plug approved charger into grounded wall outlet before plugging the charger into the machine.5.
Plug charger into grey charger receptacle located in the front left of the battery compartment.6.
Flip up the recovery tank “kick stand” and gently lay the recovery tank down until it rests on the stand.7.
The charger will automatically begin to charge the batteries, and it will automatically shut down once the batteries are fully charged.8.
Upon completion of charging, first unplug the charger from the wall outlet and then disconnect the charger from the machine.9.
Check the battery fluid level after charging is completed. If the fluid level is low, add distilled water to bring the fluid level up to the bottom of10.
