floor through a manually controlled solution valve. The
brush uses the detergent and water solution to scrub
the floor clean. As the machine moves forward, the
squeegee wipes the dirty solution from the floor into the
recovery tank.

WHILE OPERATING MACHINE
WARNING: Fire Or Explosion Hazard. Do Not
Pick Up Flammable Materials Or Reactive Metals.
1. Overlap each scrubbing path by 5 cm.
2. Keep the machine moving to prevent damage to
floor finish.
3. Wipe the squeegee blades with a cloth if blades
leave streaks. Pre-sweep the area to prevent
streaking.
4. Do not operate the machine on inclines.
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
5. Pour a recommended foam control solution into the
recovery tank if excessive foam appears.
ATTENTION: Check for excessive foam in the
recovery tank. Empty tank if excessive. Foam may
not activate the shut--off float which may result in
vacuum motor damage.
6. For heavily soiled areas, use the double scrubbing
method. First scrub the area with the squeegee up,
let solution set for 3--5 minutes, then scrub the area
a second time with the squeegee down.
7. When leaving the machine unattended, remove the
key and set the parking brake, if equipped.
BATTERY DISCHARGE INDICATOR
The battery discharge indicator displays the charge
level of the batteries. When the batteries are fully
charged, all indicator lights are lit. As the batteries
discharge, the indicator lights will begin to go out from
right to left.
To prolong the life of the batteries, do not allow the
indicator lights to go beyond the discharge level as
described below.
NOTE: ONLY recharge the batteries when the machine
is used for a total of 30 minutes or more.
When the discharge level reaches the last yellow light,
the light will begin to flash, stop scrubbing and recharge
the batteries (Figure 21). If the red light appears, the
scrubbing function will shut off automatically. This
protects the batteries from total discharge. Recharge
the batteries immediately.
Stop scrubbing and
recharge batteries
FIG. 21
CIRCUIT BREAKER
The machine is equipped with a resettable circuit
breaker to protect the brush motor from damage. The
circuit breaker button is located on the control panel
(Figure 22). If the circuit breaker should trip, determine
the cause, allow the motor to cool, and then manually
reset the circuit breaker button.
FIG. 22
HOUR METER
The hour meter records the number of total hours the
brush motor has been powered on. Use the hour meter
to determine when to perform recommended
maintenance procedures and to record service history
(Figure 23).

DRAINING TANKS
The recovery tank should be drained and cleaned out
after every use. The solution tank should be cleaned
out periodically to remove any water deposit buildup.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, turn off machine and remove
key.
DRAINING RECOVERY TANK
1. While holding the drain hose upward, remove the
cap and lower hose to drain (Figure 24).
FIG. 24
