WARNING: Flammable materials or reactive
metals can cause explosion or fire. Do not pick
up.
ATTENTION: Always start machine out slowly to
prevent machine from leaping forward.
7. View amount of solution flow on floor and adjust
solution control lever to desired solution flow.
8. To stop scrubbing, release control grips.
WHILE OPERATING MACHINE
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
1. Periodically check for foam buildup in recovery
tank (look through clear lid). If excessive foam
buildup begins to develop, pour a recommended
foam control solution into recovery tank.
ATTENTION: Do not allow foam or water to enter
vacuum standpipe, vacuum motor damage will
result. Ball float shutoff will not keep foam out of
standpipe. Vacuum damage due to foam or water
is not covered by warranty.
2. If more scrubbing pressure is needed for small
heavily soiled areas, follow steps below:
a. Lower brush.
b. Lift brush pressure lever to the locked position
(Figure 16).
NOTE: Brush MUST be down to allow brush pressure
lever to be lifted to the locked position. Do not leave
lever in the lock position when brushes are raised.
FIG. 16
3. If squeegee leaves streaks, raise and wipe blades
with a cloth. Pre–sweep area to prevent streaking.
4. Before stopping or turning machine around, pull
back on solution control lever to shut off solution
flow.
5. During brief stops, you do not have to turn off
brush switch, the brush will automatically stop
when control grips are released.
6. While cleaning, view clear tube gallon marker for
remaining cleaning solution. Each mark on hose
indicates 19 liters (5 gal).
7. Periodically check battery meter discharge level.
When needle drops to the red zone, recharge
batteries.
ATTENTION: Do not continue to run machine
when battery meter needle is in the red zone,
battery damage will result.
8. When solution tank runs dry, turn off brush switch,
shut off solution control lever and continue to
vacuum until all dirty water is consumed. Then
drain recovery tank. (See DRAINING TANKS).
CIRCUIT BREAKERS
The machine is equipped with (4) circuit breakers to
protect motors from damage. If circuit breakers trip,
they cannot be reset immediately. Determine reason
why breaker tripped, allow motor to cool and then
reset. Brush motor circuit breakers will trip due to
excessive overload on pad. Clean or change pad if
breaker should trip. Circuit breaker buttons are
located at rear of machine as shown (Figure 17).
FIG. 17
NOTE: When servicing machine or when machine is
left unattended, pull out the Main Power circuit breaker
button. This will shut off all power to machine.

DRAINING TANKS
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.
DRAINING RECOVERY TANK
Recovery tank must be emptied prior to refilling
solution tank. To drain recovery tank, perform the
following steps:
ATTENTION: If recovery tank is not emptied
between fill–ups, foam or water will enter vacuum
standpipe and damage vacuum motor. Float
shut–off screen will not keep foam out of
standpipe. Vacuum damage due to foam or water
is not covered by warranty.
1. Remove drain hose from holder, position hose
over floor drain and twist off drain hose plug. To
completely drain recovery tank, hinge open tank
and flip up tank support stand to rest tank on
(Figure 18).
NOTE: If using a bucket to drain machine, do not use
same bucket for filling solution tank. This will prevent
possible solution line clogs.
FIG. 18
2. Rinse out recovery tank after each use. This will
prevent foul odor buildup. Use a hose to rinse out
the recovery tank. Be careful not to spray water
into shut–off float screen.
3. Replace drain hose plug tightly when tank is
empty.
DRAINING SOLUTION TANK
To drain leftover cleaning solution from solution tank,
follow steps below:
1. Pull clear hose off hose barb at rear of machine
and drain solution into floor drain or bucket
(Figure 19).
FIG. 19
2. Rinse out solution tank with clean water after each
use and flush out solution flow system by pushing
solution flow lever forward. This will prevent
clogging due to chemical buildup. Use clear hose
to drain solution tank.
3. Reconnect clear hose to hose barb. Be certain
hose is completely pushed onto hose barb.
