2. Make sure the voltage of machine conform to
local voltage.
3. Check that squeegee is properly installed.
4. Check that brush / pad is properly installed.
5. Bumper doesn’t touch the floor directly. The
gap between the bumper and the floor surface
can be adjusted by adjusting sliding plate.
6. The forward speed of machine can be
controlled by turning the butterfly nut. Turn
the nut clockwise to speed up machine. or turn
the nut anticlockwise to slow down machine.
7. Make sure the working surface can support the
machine weight, the gradient of the floor can’t
exceed the limit that machine allow.
INSTALLING PAD DRIVER OR BRUSH
1. Unplug machine.
2. Tilt the machine backwards, line up the drive
pulley hub with the hole of brush or pad driver,
make sure the three blocks are fitted into the
three slots of drive pulley.
3. If a pad driver is being used, the appropriate
pad should be attached to the pad driver first.
4. Plug power cord into a grounded outlet, switch
on the brush motor and then pull the operating
triggers gently to mount the pad driver or
brush automatically.
INSTALLING THE SQUEEGEE
1. Loosen the two knobs on the squeegee and
slide the squeegee into the slots at the rear of
the squeegee bracket. (the wheels on the
squeegee point to the back)
2. Tighten the knobs securely.
FILLING THE SOLUTION TANK
1. The fill port is located at the rear of machine.
2. Fill solution tank with water. (water
temperature should not exceed 104° F) The
clear tube in the back right of the machine has
gallon markers to help determine the water
level in the solution tank
: Do not put any flammable materials
into solution tank. This can cause an explosion or
a fire. Only use recommended cleaning chemicals.
Contact your janitorial supply distributor for
recommendations on proper chemicals.
MACHINE OPERATION
: Do not operate machine unless you
have read and understand this manual.
1. Adjust control housing to a comfortable
operating height by squeezing together the two
thumb levers directly underneath the housing.
2. Lower squeegee assembly to the floor.
3. Turn brush motor switch to “on” position.
4. Turn vacuum motor switch to “on” position.
5. Rotate the ball valve of solution tank to
horizontal position. Solution will not begin to
flow until the operating triggers are pulled.
6. To begin scrubbing, pull on one or both of the
red operating triggers, when these triggers are
pulled, the pad driver will begin to spin and
the solution will begin to flow.
7. Begin scrubbing by moving the machine
forward.
: Do not keep the machine in the same
position with the pad / brush spinning, or you
could cause damage to the floor.

8.Adjust solution flow by adjusting the position
of ball valve knob.
WHILE OPERATING MACHINE
1. 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 the
recovery tank.
: Foam must not enter the float shut-off
screen, or damage can occur to the vacuum motor.
Foam will not activate the machines float shut-off
device.
2. Occasionally view the clear tube at the back
right of themachine tocheck the amount of
cleaning solution that is right of the machine.
If the squeegee assembly leaves streaks on the
floor, raise the squeegee off the floor and wipe the
blades down with a damp cloth.
: Do not use your fingers to wipe or
remove debris from the blades, as injury may
occur.
When the solution tank runs empty, turn off the
brush switch and ball valve of solution tank.
Keep the squeegee down and continue to vacuum
until all the dirty water is picked up.
TANK DRAINING
1. Turn the switches on the control panel to
“off ” position.
2. Raise the squeegee, transport machine to
approved area for draining tank(s).
DRAINING THE RECOVERY (DIRTY) TANK
: Any time scrubbing is completed, or when
refilling solution tank, the recovery tank should be
drained and cleaned.
: 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.
1. Remove the drain hose from the holder, and
place the drain hose over the floor drain.
Twist off the drain hose plug to begin the
draining process.
2. Clean the recovery tank after every use. Use a
fresh water hose to rinse out the recovery tank.

it down with a damp towel. Be sure to store
the squeegee in the up position.
4. Remove the float shut-off assembly and rinse
it out with clean water.
5. Clean machine with an approved cleaner and a
damp towel. Don’t spray water to clean the
outside of machine to avoid damage to motor
