OPERATING FaSTSCRUB SYSTEM (OPTION)
How the FaSTtSystem operates (Foam Scrubbing
Technology). The FaSTtPAK 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 disks 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 FaSTtsystem 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 FaSTtPAK of concentrated
agent allows you to scrub up to 1 million sq. ft.
1. Make sure that the FaSTtPAK MP Hard Floor
Concentrate carton is properly installed
(See INSTALLING FaSTtPAK 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 FaSTtsystem failure.
3. Press the FaSTtScrub/Conventional Scrub
Switch toward the FaSTtScrub mode position
(Figure 20).
NOTE: To scrub with clear water only, simply press
the FaSTScrub/Conventional Scrub Switch toward
the Conventional Scrub mode position. This allows
you to operate the machine in a rinsing application.
FIG. 20
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.
WHILE OPERATING MACHINE
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
WARNING: Do Not Use Flammable Liquids Or
Operate Machine In Or Near Flammable Liquids,
Vapors Or Combustible Dusts.

increase or decrease water flow, adjust solution
control knob (Figure 21).
NOTE: When scrubbing with the FaSTOption, the
solution flow knob is inactive.
FIG. 21
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 pads when worn.
8. Stay clear of floor obstructions, such as electrical
plates or grates, they will destroy pads.
9. During brief stops, you do not have to turn off any
