HOW THE MACHINE WORKS
Conventional Scrubbing (Standard Model):
Water and detergent from the solution tank flow to the
floor through a manually controlled solution valve. The
brush uses the detergent and water solution to scrub
the floor clean. As the machine moves forward, the
squeegee wipes the dirty solution from the floor into
the recovery tank.
Foam Scrubbing (FaST Model):
(FaST-- Foam Scrubbing Technology)
Unlike conventional scrubbing, the FaST system
injects the patented FaST--PAK concentrate formula
with a small amount of water and air onto the floor.
The mixture creates a large volume of expanded wet
foam for the brush to scrub the floor clean. As the
machine moves forward, the foam collapses and the
squeegee wipes the dirty solution into the the recovery
tank leaving the floor completely dry and slip free.
The foam scrubbing application (FaST) can increase
productivity by 30% by reducing the dump/fill cycle. It
will also reduce chemical usage and storage space.
One FaST--PAK can scrub up to 90,000 sq. meters.
NOTE: The FaST model can also be operated as a
conventional scrubber. However, it’s important that you
follow the instructions in this manual to prevent FaST
system failure.

SQUEEGEE BLADE ADJUSTMENT
For optimum squeegee blade performance, the
squeegee assembly casters must be adjusted to a
specified height as described below.
1. To check the squeegee assembly for proper
adjustment, remove the squeegee assembly from
the machine and place it on a level surface.
Measure the distance between the caster and the
surface. It should measure approximately 3 mm
(Figure 55).
2. To adjust the caster height, loosen the top nut and
remove the plastic bearing cover to access the
adjustment nut. Turn the adjustment nut until
properly adjusted (Figure 55). After adjusting,
tighten the top nut and replace the plastic bearing
cover. Repeat step for the other caster.

BATTERY MAINTENANCE (Lead Acid Batteries)
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 57). 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.

NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_C, the
reading must be temperature corrected. Add or
subtract to the specific gravity reading 0.004, 4 points,
for each 6_C above or below 27_C.
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 58).
DO NOT OVERFILL.
