OPERATION
10 SpeedScrub1701 Plus (12–00)
FIG. 24
NOTE: On rough surfaces it may be necessary to
reduce brush pressure.
5. Check the brush meter pressure when scrubbing.
Only operate machine in green zone. Never
operate machine in red zone (Figure 25).
NOTE: If brush pressure adjustment is required, see
MACHINE ADJUSTMENTS.
FIG. 25
ATTENTION: To prevent possible floor damage
and brush circuit breakers from tripping, do not
operate brush pressure meter in red zone.
6. To operate machine in reverse, simply pull the
machine backwards while pulling triggers.
7. To stop scrubbing, release brush triggers, turn off
all switches, and raise scrub head and squeegee.
OPERATING EXTENDED SCRUB OPTION

solution tank for operation.
2. Turn on ESswitch. During operation the ES
pump will automatically start recycling when ES
pump on light turns on (Figure 26).
FIG. 26
3. When finished scrubbing, drain and rinse solution
tank and clean ESfilter (See DRAINING
TANKS).
WHILE OPERATING MACHINE
WARNING: Flammable materials or reactive
metals can cause explosion or fire. Do not pick
up.
1. Observe amount of solution flow on floor. If
solution flow adjustment is needed, see MACHINE
ADJUSTMENTS.
2. Periodically check for foam buildup in recovery
tank (look through clear lid). If excessive foam is
developing, pour a recommended foam control
solution into recovery tank.
ATTENTION: Do not allow foam or water to enter
ball float screen, vacuum motor damage will
result. Foam will not activate ball float. Vacuum
motor damage due to foam or water is not covered
by warranty.
3. Always operate with caution when scrubbing
around walls or obstacles.
4. If squeegee leaves streaks, raise and wipe blades
with a cloth. Pre-sweep area to prevent streaking.
If squeegee adjustment is necessary, see
MACHINE ADJUSTMENTS.
5. Overlap each pass by 50mm (2 in).
6. Change or turn over pads when dirty.
7. Stay clear of floor obstructions, such as electrical
plates or grates, they will destroy pads.
8. During brief stops, you do not have to turn off any
switches, the brushes and solution flow will
automatically stop when triggers are released.
9. Periodically check battery meter discharge level.
When needle drops to the red zone, recharge
batteries.

OPERATION
11
SpeedScrub1701 Plus (12–00)
ATTENTION: Do not continue to operate machine
when battery meter is in the red zone, battery
damage will result.
10. On last scrubbing pass, turn off solution switch
just prior to stopping machine. This will allow total
recovery pick up.
11. When solution tank runs dry, drain recovery tank.
(See DRAINING TANKS).
CIRCUIT BREAKERS
The machine is equipped with two circuit breakers to
protect machine from damage. The Main (20amp) and
Brush (35amp) circuit breakers.
If circuit breakers should trip, the breakers will not
reset immediately upon tripping. Determine reason
why breaker tripped, wait a few minutes and reset
(See TROUBLE SHOOTING).
Brush motor circuit breakers will trip due to excessive
overload on pad. Reduce pad pressure or replace pad
if breaker trips. Circuit breakers are located on control
console (Figure 27).
FIG. 27
MACHINE ADJUSTMENTS
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.

turn adjustment knob. Adjustment knob is located near
brush lift pedal (Figure 28).
FIG. 28
ADJUSTING PAD PRESSURE
NOTE: On rough surfaces it may be necessary to
reduce brush pressure.
To adjust pad pressure, turn adjustment knob
clockwise to decrease or counterclockwise to increase
pad pressure. Adjustment knob is located below brush
lift pedal (Figure 29).
FIG. 29
ADJUSTING SQUEEGEE LIFT CABLE
To adjust squeegee lift cable, loosen lock nuts and
turn adjustment stem on squeegee cable. Retighten
lock nuts after adjusting (Figure 30).

Explosion or fire can result. Keep sparks and
open flame away. Keep battery compartment open
when charging.
FOR SAFETY: When servicing machine, wear
protective gloves when handling batteries or
battery cables. Avoid battery acid.
1. Always follow proper charging instructions (See
BATTERY CHARGING).
2. Each week after charging, check fluid level (A) in
each battery cell of all batteries. The level should
reach bottom of sight tubes (B). If needed, add
just enough distilled water to reach bottom of sight
tubes. DO NOT overfill (Figure 38).

water.
b. Brush solution sparingly over battery tops,
terminal and cable connectors.
NOTE: Do not allow baking soda solution to enter
battery cells.
c. Use wire brush to clean terminal post and
cable connections.
d. After cleaning, apply a coating of clear battery
post protectant to terminals and cable
connections.
4. Check for loose or worn cables. Replace if worn.
