OPERATING FaST SCRUB SYSTEM (FaST
MODEL)
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 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 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 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 may
result in premature FaST system failure.
3. Make sure that the main and brush switches are in
the on position, and pull the solution flow lever all
the way back (Figure 21).
FIG. 21
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 Lever during the
FaST Scrub mode.
4. Press the FaST Scrub/Conventional Scrub Switch
toward the FaST Scrub mode position -- switch
light will come on (Figure 22).
NOTE: The solution flow lever must be in the pulled
back position in order to activate the switch.
FIG. 22
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.
5. Follow the standard MACHINE OPERATION
instructions to begin scrubbing.

BATTERY MAINTENANCE
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing machine, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
1. Check the specific gravity using a hydrometer to
determine the charge level and the condition of the
batteries (Figure 37). If one or more of the battery
cells read lower than the other battery cells (0.050
or more), the cell is damaged, shorted, or is about
to fail. Check the hydrometer readings against the
following chart to determine the remaining battery
charge level.
NOTE: Do not take readings immediately after adding
distilled water. If the water and acid are not thoroughly
mixed, the readings may not be accurate.
FIG. 37
SPECIFIC GRAVITY
at 27_C(80_F) BATTERY

1.265 100% CHARGED
1.223 75% CHARGED
1.185 50% CHARGED
1.148 25% CHARGED
1.110 DISCHARGED
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_C(80_F),
the reading must be temperature corrected. Add or
subtract to the specific gravity reading 0.004, 4 points,
for each 6_C(43_F) above or below 27_C(80_F).
2. Always follow proper charging instructions
(See CHARGING BATTERIES).
3. Check the electrolyte level (A) in each battery cell
after charging batteries. The level should be
approximately 1 cm from the bottom of the fill--port
(B). Add distilled water if needed (Figure 38).
DO NOT OVERFILL.

4. Keep the battery tops clean to prevent battery
corrosion.
To clean batteries:
FOR SAFETY: When servicing machine, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
a. Mix a strong solution of baking soda and water
(Figure 39).
FIG. 39
b. Brush the solution sparingly over the battery
tops and cable connectors.
NOTE: Do not allow baking soda solution to enter
battery cells.
c. Use a wire brush to clean the battery terminals
and cable connectors.
d. After cleaning, apply a coating of clear battery
post protectant to the terminals and cable
connectors.
5. Check for loose or worn cables. Replace if worn.
DRIVE CHAIN MAINTENANCE
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.
Inspect drive chain for proper tension. Chain should
flex between 6.35mm (0.25 in.) and 12.7mm (0.50 in.)
from center. If chain flexes more than 12.7mm
(0.50 in.), chain should be tightened. To tighten chain,
follow steps below:
1. Turn main switch to the off position and pull out
the main circuit breaker button.
2. From operators right side of machine, locate and
loosen 4 motor mount bolts, do not remove bolts.
3. Loosen locking nut on tension bolt (Figure 40).
