MACHINE PREPARATION
4) SQUEEGEE ASSEMBLY INSTALLATION
The squeegee is assembled to the machine
by lifting the locking latches and sliding the
squeegee assembly onto the 2 posts at the
rear of the squeegee swing arm. Push on the
locking latches down. Lower the squeegee
and install vacuum hose over vacuum outlet
on squeegee assembly. The hose should be
located to the rear of the lifting cable.
5) ADJUSTING SQUEEGEE HEIGHT
The height from floor to squeegee should be
adjusted based on blade wear. Rotate the
adjusting knobs counter-clockwise to lower
squeegee and clockwise to lift it.
NOTE: Rotate the right and left adjusting
knobs until the squeegee is positioned parallel
to the floor.
6) ADJUSTING SQUEEGEE INCLINATION
During operation the rear squeegee blade is
most efficient when bent backwards roughly
3/16ths to 5/16ths of an inch along its entire
length. To increase the blade bending in the
center of the squeegee, tilt the squeegee body
backward by turning the adjuster knob
counter-clockwise. Conversely, turn the
adjuster knob clockwise to increase the
bending at the outside edges of squeegee
blade.

7) RECOVERY TANK
Open the lid and confirm the following
connections are secure:
a) The vacuum cover is securely attached.
Align the notches and rotate the cover
clockwise to close. The vacuum hose
must also be attached.
b) Confirm that the squeegee hose is properly
connected.
c) Confirm that the drain hose plug, which is
located at the front of the machine, is
closed.
8) SOLUTION WATER
Fill the solution tank with clean water at a
temperature not higher than 50°C / 122°F. Add
the proper concentration of liquid detergent by
following the manufacturer instructions. Excess
foam in the recovery tank can damage the
vacuum motor, so use only the minimum amount
of detergent necessary. Reassemble the cover.
WARNING! Always use low foaming
detergent. Adding antifoam liquid into
the recovery tank before cleaning will also help
prevent foaming.
NEVER USE ACID, BLEACH or AMMONIA
9) BRUSH INSTALLATION
a) Lift the brush base by depressing the foot
level at the rear of the machine.
b) Place the brushes under the base. Align
the brush lugs with the holes in the brush
plate. Insert the brushes into the plate and
turn each brush so the lugs are pushed
toward their retaining springs, until locked.
The photo shows the directions to rotate
the brushes to lock them into operating
position.

MACHINE OPERATION
1) Connect machine connector to the battery
connector.
2) Turn on the main power key switch. Battery
charge indicator will illuminate indicating the
charge level of the batteries. If the indicator is
flashing the batteries need to be charged.
3) Turn on the brush motor switch. Please note
that the scrubbing brush will not rotate until
the hand switch lever is engaged.
4) Turn on the water solenoid valve switch.
5) Turn on the vacuum motor switch.
6) Adjust the flow rate of the cleaning solution
with lever. Moving the solution flow control
lever downward increase the flow rate and
raising the lever decreases the flow rate.
There should be enough solution to wet the
floor uniformly, but not so much thatthe water
gets past the splash guard. Remember that
the correct solution quantity depends on the
type of floor, the dirt level and the scrubbing
speed.
7) Release parking brake by raising parking
brake lever.
8) Release and raise the brush base lift lever to
lower the brush base.
9) Lower the squeegee using the squeegee lift
lever.

MACHINE OPERATION
10)SCRUBBING
This machine is equipped with brush assist
propulsion. Depress the handle switch lever.
The scrub brush will begin to rotate and solution
will begin to flow. During the first few yards of
operation, check that the quantity of the cleaning
solution is sufficient to wet the floor and that the
squeegee dries the floor surface.
WARNING! Always lift the squeegee when
moving backwards.
11)OVER FILL PROTECTION
The machine is equipped with a float that stops
the vacuum exhaust air flow when the recovery
tank is full. Vacuum motor does not stop
operating but the vacuum exhaust air flow rate is
greatly reduced. When this occurs, empty the
recovery tank by removing the drain plug on the
drain hose and then empty the recovery tank.
WARNING! Use gloves for protection from
contact with dangerous solutions.

TROUBLE SHOOTING GUIDE
1) INSUFFICIENT WATER TO THE BRUSHES
a) Make sure the solution flow control valve is open.
b) Confirm that there is water in the solution tank.
c) Make sure solution dispensing tubes are not clogged or
obstructed.
2) THE MACHINE DOES NOT CLEAN SATISFACTORILY
a) Check the condition of the brush or pad and replace them if necessary.
b) The brush should be replaced when the bristles reach a length of 5/8 inches (15mm).
3) THE SQUEEGEE DOES NOT DRY THE FLOOR WELL
a) Check that the squeegee blades are clean.
b) Adjust the inclination of the squeegee.
c) Confirm the vacuum hose is correctly fitted into its port in therecovery tank and free
from obstructions.
d) Replace the squeegee blades if worn.
e) Check that the vacuum motor switch is on.
f) Check the squeegee height adjustment (see "MACHINE PREPARATION" section).
4) EXCESSIVE FOAM PRODUCTION
a) Check that a low foaming detergent has been used. If required, add asmall quantity of
defoamer liquid to the recovery tank. More foam is generated when a floor is lightly
soiled. Use less detergent if this is the case.
