maximum. The clear hose at rear of machine
indicates amount of water in solution tank
(Figure 13).
NOTE: The water must not be hotter than 60_C
(140_F) or tank damage may occur.
NOTE: If filling with a bucket be certain that bucket is
clean. This will prevent possible solution line clogs.
FIG. 13
4. For conventional scrubbing, pour a recommended
cleaning detergent into the solution tank according
to mixing instructions on bottle. For FaST
scrubbing (Option), DO NOT add cleaning agents in
solution tank.
ATTENTION: For Conventional Scrubbing, only
use recommended cleaning detergents. Machine
damage due to improper detergent usage will void
the manufacturer’s warranty.
WARNING: Fire or Explosion Hazard.
Never Use Flammable Liquids.
FOR SAFETY: When using machine, follow mixing
and handling instructions on chemical containers.
5. If equipped with ES option, pour between 19 and
38 liters (5 and 10 gal) of hot water, 60°C (140°F)
maximum, into recovery tank (Figure 14) (See
OPERATING ES OPTION).
NOTE: The water must not be hotter than 60_C
(140_F) or tank damage may occur.
NOTE: If filling with a bucket be certain that bucket is
clean. This will prevent possible solution line clogs.
FIG. 14
MACHINE OPERATION
FOR SAFETY: Do not operate machine, unless
operation manual is read and understood.
WARNING: Fire Or Explosion Hazard. Never
Operate Machine In Or Near Flammable Liquids,
Vapors Or Combustible Dusts.
PRE--OPERATION CHECKS

8. Rotate control grips completely forward and
gradually turn speed control knob to a desired
maximum scrubbing speed (Figure 21).
FIG. 21
9. Turn solution flow knob to desired solution flow
rate (Figure 22).
NOTE: When scrubbing with the FaST Option, the
solution flow is pre-set by the FaST system.
FIG. 22
10. Observe brush pressure meter while operating.
Meter should read within the green zone, press
brush pressure switch to adjust (Figure 23).
ATTENTION: Do not operate machine with pad
pressure meter in red zone, circuit breakers will
trip and floor damage may occur.
FIG. 23
11. To operate machine in reverse, gradually rotate
control grips backwards.
12. To stop scrubbing, release control grips, raise
scrub head and squeegee.
13. After scrubbing, perform the Daily Maintenance
procedures (See MACHINE MAINTENANCE).
EMERGENCY STOPPING (OPTION)
In the event of an emergency while operating, strike
the power kill button at rear of control console to halt
machine. Turn button clockwise to reset (Figure 24).
FIG. 24
OPERATING FaST SCRUB SYSTEM (OPTION)
How the FaST System operates (Foam Scrubbing
Technology). The FaST--PAK concentrate agent is
injected into the system with a mixture of a small
amount water and compressed air. This mixture
creates a large volume of expanded wet foam. The
expanded foam mixture is then dispersed onto the
floor while two scrubbing discs go to work. By the time
the squeegee picks up the mixture, the patented
foaming agent has collapsed and recovered into the
recovery tank. By performing the FaST system
application, you can increase your productivity rate by
30% by reducing your dump/fill cycle. You will also
reduce your chemical usage and storage space. One
FaST--PAK of concentrated agent allows you to scrub
up to 1 million sq. ft.
1. Make sure that the FaST--PAK 365 Floor Cleaning
Concentrate carton is properly installed
(See INSTALLING FaST--PAK AGENT).
2. Make sure that the solution tank is filled with clear
cool water only. DO NOT add conventional
cleaning agents in solution tank. Conventional
cleaning agents/restorers in the solution tank will
result in premature FaST system failure.

3. Press the FaST system switch to the on ( I )
position (Figure 25).
NOTE: To scrub with clear water only, simply press
the FaST system switch to the off (O) position. This
will allow you to operate the machine in a rinsing
application.
FIG. 25
4. Make sure that the main solution switch is in the
ON position.
NOTE: The water flow rate from the solution tank is
automatically regulated by the operation of the FaST
system. The solution flow rate can not be adjusted by
the Solution Control Adjustment Knob during the FaST
Scrub mode.
5. Follow the standard MACHINE OPERATION
instructions to begin scrubbing.
General Information: The FaST and ES options can
not be equipped on the same machine.
OPERATING ES (OPTION)
ES option extends scrubbing time by reusing
recovered water. The recovered water is filtered and
recycled back into the solution tank for reuse.
NOTE: The ES Option is not available for FaST
models.
1. Pour between 19 and 38 liters (5 and 10 gal) of
hot water, 60°C (140°F) maximum, into recovery
tank when filling solution tank (Figure 26).
NOTE: The water must not be hotter than 60_C
(140_F) or tank damage may occur.
NOTE: If filling with a bucket be certain that bucket is
clean. This will prevent possible solution line clogs.
WARNING: Fire Or Explosion Hazard. Never
Operate Machine In Or Near Flammable Liquids,
Vapors Or Combustible Dusts.
FIG. 26
2. Turn ES switch on when ready to begin scrubbing.
The ES indicator light will automatically turn on
and off when recovery tank reaches its recycling
point (Figure 27).
FIG. 27
NOTE: If ES indicator light remains on, drain tanks
and clean ES filter located in recovery tank.
3. Follow the standard MACHINE OPERATION
instructions to begin scrubbing.
WHILE OPERATING MACHINE
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
1. Overlap each path by 50 mm (2 in).
2. Keep machine moving to prevent damage to finish
or floor.
3. Observe brush pressure meter while operating.
Meter should read within the green zone, press
brush pressure switch to adjust.
ATTENTION: Do not operate machine with pad
pressure meter in red zone, circuit breakers will
trip and floor damage may occur.
4. Periodically observe recovery tank for excessive
foam. Pour a recommended foam control solution
into recovery tank if excessive foam appears.

ATTENTION: Do not allow foam or water to enter
float shut-off screen, vacuum motor damage will
result; not covered by warranty. Foam will not
activate float shut-off screen.
5. For heavily soiled areas, double scrubbing is
recommended. First scrub area with squeegee up,
let solution set for 3--5 minutes, then scrub area a
second time with squeegee down.
6. Disc Scrub Head: Change or turn pads over when
worn.
7. Cylindrical Brush Scrub Head: If you experience
