SpeedScrubt2001HD (09–01) 9
WHILE OPERATING MACHINE
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
WARNING: Flammable materials or reactive
metals can cause explosion or fire. Do not pick
up.
1. Observe amount of solution flow on floor. To
increase or decrease water flow, adjust solution
control knob (Figure 17).
FIG. 17
2. Periodically observe recovery tank for excessive
foam. If excessive foam appears, pour a
recommended foam control solution into recovery
tank.
ATTENTION: Do not allow foam or water to enter
float shut–off screen, vacuum motor damage will
result. Foam will not activate float shut–off
screen.
3. Always operate at a slower speed when scrubbing
around walls or obstacles.
4. Always reduce speed to maintain control when
turning machine.
5. If squeegee leaves streaks, raise and wipe blades
with a cloth. Pre-sweep area to prevent streaking.
6. Overlap each pass by 51mm (2 in).
7. Change or turn over pad when worn.
8. Stay clear of floor obstructions, such as electrical
plates or grates, they will destroy pad.
9. During brief stops, you do not have to turn off any
switches, the brush and solution flow will
automatically stop when control grips are
released.
10. 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.
11. While cleaning, view clear tube at rear of machine
for remaining cleaning solution. Each mark on
hose indicates 19L (5 gal).
12. When solution tank runs dry, turn off brush switch,
raise brush and continue to vacuum until all dirty
water is consumed. Then drain recovery tank.
(See DRAINING TANKS).
STOPPING MACHINE
1. Turn off brush switch, raise brush and continue to
vacuum until all dirty water is consumed.
2. Release control grips.
3. Raise squeegee and scrub head.
4. Turn off switches and remove key if equipped.
5. Set parking brake if equipped.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off machine,
and set parking brake if equipped.
EMERGENCY STOPPING (OPTION)
To stop machine in case of an emergency, hit the red
power kill button located at rear of control console.
The power kill button immediately stops all power to
machine (Figure 18).
To reset power kill button, shut off all switches and
turn kill button to the right. Resume to normal
operation.
FIG. 18

OPERATION
10 SpeedScrubt2001HD (09–01)
CIRCUIT BREAKERS
The machine is equipped with (3) circuit breakers to
protect machine from damage.
If circuit breakers should trip, the breakers will not
reset immediately upon tripping. Determine reason
why breaker tripped, allow motor to cool and reset.
Brush motor circuit breaker will trip due to excessive
overload on pad. Reduce pad pressure or replace pad
if breaker should trip. Brush motor (35 amp) circuit
breaker is located near charger plug.
The main (10 amp) and drive/vacuum (35 amp) circuit
breakers are located at rear of machine (Figure 19).
FIG. 19
DRAINING TANKS
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.
DRAINING RECOVERY TANK
When finished scrubbing or when refilling solution tank
the recovery tank should be drained and cleaned.
ATTENTION: If recovery tank is not drained
before refilling, foam or water will enter the float
shut–off screen and vacuum motor damage will
result.
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
sideways and flip up tank support stand to rest
tank on (Figure 20).
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. 20
2. Clean recovery tank after each use. Use a hose to
raise out tank. Be careful not to spray water into
float shut–off.
3. Replace drain hose plug tightly after draining.
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 21).
FIG. 21
2. Rinse out solution tank and solution flow system
with clean water after each use. 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.
