red zone, battery damage will result.

11. While cleaning, view clear tube gallon marker

for remaining cleaning solution. Each mark on

hose indicates five gallons / 19 liters.

12. When solution tank runs dry, drain recovery

tank

. (See DRAINING TANKS)

STOPPING MACHINE

1. Turn off brush/solution switch, raise brushes

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.

5. Set parking brake, pull lever backwards to

set. (Figure 20)

FIG. 20

ATTENTION: Before leaving machine,

stop on level surface, set parking brake, turn

EMERGENCY STOPPING

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 21)

To reset power kill button, shut off all switches and

turn kill button to the right. Resume to normal

operation.

FIG. 21

CIRCUIT BREAKERS

The SpeedScrub models are equipped with (4)

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 breakers will trip due to

excessive overload on pad. Reduce pad pressure

or replace pad if breaker should trip. Brush motor

circuit breakers (15amp) are located near charger

plug.

The main (10amp) and drive/vacuum (35amp)

circuit breakers are located at rear of machine.
