and water for use in scrubbing.
2. Use only low foam detergents recommended by
the manufacturer. Do not use harsh solvents or corro-
sive cleaning agents in the machine.
3. Do not use a higher concentration of cleaning chemical
than what is recommended by the chemical
manufacturer.
4. Do not use water or solution hotter than 140°F
.
If you have
any questions regarding chemicals or mixing
ratio, consult chemical manufacturer instructions or your
local dealer.
Starting the Machine
1. Switch the key of the main power supply to the ON
position. (Note the power level gauge. If it does not
indicate full charge, please charge the batteries before
running the machine).
2. Pull down the squeegee lifting lever (in the middle on
the back side) to lower the squeegee assembly to the
ground.
3. Step on the brush head raise/lower pedal (on the back
side, bottom right) to lower the brush head to the ground.
4. Turn on the solution control valve (on back side, top left)
to dispense cleaning solution.
5. Turn on the brushes.
6. Turn on the vac motor.
7. Push the handlebars forward to drive forward and
backward to drive backward. Amount of pressure
determines drive speed.
Running the Machine
Warning:
Fire or explosion hazard. Do not attempt to vac
up flammable or corrosive liquids or dust, or reactive
metals.
1. Overlap each cleaning pass by 3 inches.
2. Keep machine moving while scrubbing in order to avoid
abrading floors.
3. If there are drag marks on the floor behind the squee-
gee, you may need to clean or replace the squeegee (if
it is worn down) or turn off solution flow and run scrubber
over the area again with vac turned on.
4. Do not operate the machine on any slope steeper than 2%.
5. We strongly recommend using only low foam detergents
in the scrubber. Consult your local dealer for details. If
you are getting too much foam while cleaning, we
recommend pouring a defoaming agent into the recov-
ery tank. Also try using a lower concentration of cleaner.
Note:
Do not let the foam enter the filter screen so as to
avoid damage to vacuum motor. The foam may also
damage the switch of the filter screen.
6. Use a double pass method for cleaning extremely dirty
floors. Lift squeegee assembly for first pass. Deposit
detergent and let sit for 3-5 min. Then lower the
squeegee, turn on the vac, and run the second pass.
7. Keep an eye on the power consumption of the batteries.
Normal run time for brand new batteries is about 4 hours.
8. Observe the liquid level through the liquid meter of the
solution tank (if equipped). Normal consumption for
10 minutes of operation is about 1.3 gallons.
9. When the solution tank is empty, before refilling it,
be sure to empty the recovery tank completely.
10. If the machine is to be left unattended, stop and place
the machine on level ground. Switch off power and
take out the key.
11. After running the machine, carry out daily maintenance
procedures.
Daily Maintenance
1. Turn off solution flow with lever on top left of back side.
2. Turn off brushes and vac with switches on control panel.
3. Raise squeegee assembly with lifting lever on back side.
4. If solution tank is not completely
empty, push machine to drain-
age area and open valve to
allow solution tank to drain out
(see picture).
5. Drain, flush, and clean recovery tank (see following sec-
tion). Leave tank open and allow to air dry.
6. Clean squeegee and inspect for wear. If working edge
is not square, reposition or replace as needed. (See
“Installation and Replacement of Squeegee”).
7. Wipe down with machine with cloth and multipurpose
cleaner.
8. Check vac filter. Clean or replace if necessary.
