(Figure 23).
FIG. 23
NOTE: The solution flow and brush will not start until
brush triggers are pulled.

EN ENG ISH
10 5100(02–01)
4. Pull brush triggers and begin walking with
machine. The brush will propel the machine
forward allowing little effort maneuvering the
machine (Figure 24).
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, raise scrub head and squeegee.
OPERATING EStMODEL
EStModel allows extended scrub time by reusing
recovered water. The recovered water is filtered and
recycled back into the solution tank for reuse.
1. Fill recovery tank with 13L (3.5 gal) when filling
solution tank for operation.
2. Turn on EStswitch. During operation the ESt
pump will automatically start recycling when ESt
pump on light turns on (Figure 26).
FIG. 26
3. When finished scrubbing be certain to drain and
rinse solution tank and to clean EStfilter (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 5cm (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.

ENG ISH EN
5100(02–01) 11
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 of stopping machine. This will allow total
recovery pickup.
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 and Brush
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 should trip. 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.
ADJUSTING SOLUTION FLOW
To increase or decrease the maximum solution flow,
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
counter–clockwise to increase or clockwise to
decrease pad pressure. Adjustment knob is located
below brush lift pedal (Figure 29).
FIG. 29

12 5100(02–01)
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).
FIG. 30
DRAINING TANKS
When finished scrubbing, or when solution flow stops,
or when float shut–off screen is activated, or squeegee
starts trailing water during operation, the recovery tank
should be drained.
Always drain tanks and rinse recovery tank with clean
water after each use. If you used the EStrecycling
system, be certain to drain and rinse solution tank,
also.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.
DRAINING RECOVERY TANK
ATTENTION: Drain recovery tank when refilling
solution tank. Foam or water may enter float
shut–off screen and damage vacuum motor.
Vacuum motor damage due to foam or water is
not covered by warranty.
1. Push machine to floor drain and turn off all
switches. Remove left side drain hose from holder,
position hose over drain and twist loose and
remove drain hose plug
(Figure 31).
FIG. 31
NOTE: If using a bucket to drain machine, do not use
same bucket for filling, or be certain to rinse it out
before refilling machine.
2. Open clear recovery tank lid and rinse tank, ball
float screen and EStfilter if equipped. Remove
and rinse float shut–off screen and EStfilter if
they are excessively dirty. Replace screen and
filter securely.
3. Replace drain hose plug securely when empty.
DRAINING SOLUTION TANK
To drain unused cleaning solution or recycled solution
from solution tank, follow steps below:
1. Remove clear drain hose from hose barb, position
hose over drain (Figure 32).
FIG. 32
2. Rinse out solution tank and solution flow system
with clean water to prevent clogging due to
chemical buildup.
