HOW THE MACHINE WORKS
The Saber Cutter is a battery powered, self-
propelled, hard floor scrubber intended for
commercial use. The appliance applies a
cleaning solution onto a hard floor, scrubs the
floor with brushes, and then vacuums the soiled
water back into the recovery tank.
The function of the recovery system is to vacuum
the soiled water back into the recovery tank. The
recovery system consists of two squeegees,
vacuum motor, float ball filter, recovery tank and
controls. The squeegees wipe the dirty solution
off the floor as the machine moves forward. The
vacuum motor provides suction to draw the dirty
solution off the floor and into the recovery tank.
The recovery tank stores the dirty solution. The
float ball filter protects the vacuum fan from debris
and shuts off air going to the recovery tank when
tank is full. When flow of air is shut off the vacuum
motor will continue to run. At this time the
The machine's primary systems are the solution
system, scrub system, recovery system, and
directional control system.
The function of the solution system is to store
cleaning solution and deliver it to the scrub
system. The solution system consists of the
solution tank, strainer, valve and controls. The
solution tank stores cleaning solution (water and
detergent) until it is delivered to the scrub system.
The strainer protects the valve from debris. The
valve is a solenoid type valve, which controls the
delivery of cleaning solution to the scrub system.
The valve automatically prevents solution flow
unless the scrub brushes are turned on and the
machine is being propelled. The solution control
knob controls the amount of cleaning solution
delivered to the scrub system by controlling the
amount of time the valve is open.
recovery tank must be drained.
The function of the directional control system is to
control the direction and speed of the machine.
The directional control system consists of the
propel control buttons, reverse button, speed
control knob/potentiometer, controller and
transaxle. The propel controls actuate switches
which cause the machine to move forward. For
reverse motion depress the reverse button while
depressing one of the propel controls. The speed
control knob actuates a potentiometer, which
signals speed. The controller interprets the
forward/reverse signals from the switches and the
speed signal from the potentiometer to command
the transaxle to propel the machine in the
The function of the scrub system is to scrub the
floor. The scrub system consists of three rotary
type disk scrub brushes, motors, scrub deck skirt,
lift mechanism, swing mechanism and controls.
The brushes scrub the floor and the motors drive
the brushes. The brush drive hubs allow the
scrub brushes to follow irregularities and changes
in the floor without loosing contact with floor. The
scrub deck skirt controls the cleaning solution on
the floor so that the squeegee can pick it up. The
brush lift mechanisms are controls used to raise
and lower the deck. The brush swing
direction, and at the speed, desired.
mechanisms are controls used to swing the deck
in and out.

MACHINE OPERATION
SOLUTION TANK
DOUBLE SCRUB
1. Loosen small drain hose from the retainer, then
lower hose in direction of the drain.
For floors which are heavily soiled or have thick
accumulations of floor finish may not clean
sufficiently with one pass. In these cases it will be
necessary to double scrub.
2. Remove the solution tank cover.
To double scrub, make the first pass over the
surface being cleaned with both squeegees up,
vacuum off, the solution on and brushes down. This
allows the solution to stay in contact with the soil
while loosening the surface accumulation with the
brushes. Allow time for the first application to stay in
contact with the floor. Length of time between the
first and second pass depends on amount of
accumulation and the type of chemical being used.
A second scrubbing with both squeegees down and
again the solution and brushes on will further loosen
soil. The additional application of solution will further
assist the difficult cleaning job.
3. Flush the solution tank out with clean water and
run several gallons of clean water through
systems. Do not use water hotter than 140°F
(60°C) to clean tank. Damage may occur.
NOTE: Never allow solution to remain in tank.
Damage to tank, seals and valves could occur.

damage, wear, and adjustment each day in the pre-
run check. Change the front blade if it is torn or has
an uneven edge. Change the rear blade if it is less
than 1/2 the original thickness.
ADJUSTING SQUEEGEE
Adjusting the squeegee is a two-part process. First,
the squeegee assembly must have correct pitch in
order for the squeegee blade to have the same
deflection at each tip as well as the center. The
knob on the squeegee linkage controls the pitch
adjustment. The second adjustment is the
deflection. Knobs on each end of the squeegee
control this.

indicate when the squeegee is adjusted
properly. When the air bubble is in the center of
the vial, the deflection should be even across
the squeegee blade.
4. To decrease the deflection of the squeegee
blade at the ends, tighten knob near the
squeegee center. To increase the deflection at
the ends of the squeegee assembly, loosen
knob.
1. Choose a smooth, level surface. Lower the

machine; stop on level surface, turn off machine
and remove key.
3. Observe the amount of squeegee deflection. It
should deflect 3/8 in. (9.5mm) across the entire
width of the squeegee.
4. To increase the squeegee deflection, turn the 2
knobs at the squeegee ends counter-clockwise.
To decrease the deflection, turn the knobs
clockwise.
NOTE: The deflection should be consistent along
the length of the squeegee. If the deflection varies
from end to end the knobs can be adjusted
independently to correct the variation.
5. Turn on the key switch. Raise, then lower
squeegee assembly. Drive forward at least
2 feet (60cm).
5. Check the deflection of the squeegee blades
again. Repeat steps 1 through 4 until the

There are four different types of brushes available to
cover applications from cleaning heavily soiled floors
to polishing. A pad driver is also available to take
advantage of the many cleaning pads on the market.
Please refer to the following to assist in selecting the
proper brush or pad for the work at hand.
1. With the scrub deck up, turn “OFF” the machine.
FOR SAFETY: Before leaving or servicing the
machine; stop on level surface, turn OFF
machine and remove key.
UNCOATED FLOORS
2. Lift the appropriate brush release access cover.
Aggressive Grit is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
3. Locate release lever on top of brush or pad
driver. Rotate release lever counter-clockwise
and the brush/pad driver will release and drop
down.
Mild Grit is a less aggressive silicone carbide grit
suitable for cleaning medium soil conditions.
Advantages are faster ground speed than nylon
bristles on light solid applications.
4. To reinstall, center the brush driver under the
brush drive hub. Raise until it contacts brush
driver assembly. Turn clockwise until release
lever plate locks into position.
Polypropylene is a general-purpose scrub brush
with stiff bristles. Polypropylene works well for
maintaining concrete, wood and tile floors.
NOTE: Check that release plate is completely
closed and pad/brush is securely attached. Damage
to driver or brush could occur.
FINISHED FLOORS
4. RECOVERY TANK FLOAT SHUT-OFF
Nylon bristles are used in a variety of applications
on coated or uncoated surfaces.
When water is no longer being vacuumed from the
floor and the vacuum fan is operating, the ball float
has engaged. The vacuum motor will not vacuum
water with recovery tank full. The recovery tank
must be drained.
White Pads (Polishing) are used for dry polishing to
achieve a high-gloss appearance, or surface
washing on highly polished or burnished floors.
Red Pads (Buffing) are used for light-duty
scrubbing. When used with a mild detergent they
will provide surface cleaning without removing the
finish.
1. The float shut-off screen can be cleaned in or
out of the machine.
2. To clean the float shut-off while it is inside the
machine wipe material off screen then rinse.
Check that the ball is also clean and moves
freely.
Blue Pads (Scrubbing) are used for heavy-duty
scrubbing and light stripping. The blue pads remove
less finish than brown stripping pads, yet will remove
black marks, stains and dirt.
3. To remove the float shut-off, grasp the screen
with one hand and the connected tube with the
other. Tilt and pull the float screen assembly to
pull it off the barb on the tube.
Black Pads (Stripping) are used for easy and
complete removal of old floor waxes/finishes. They
will quickly remove ground in dirt, black heel marks,
and spills. When used with the proper stripper, this
pad leaves the floor clean and ready for finishing.
To install, place one hand on the tube, and then
tilt and push the float screen assembly over the
barb on the tube.
The scrub brushes should be checked before each
days work for wire, string, wear and damage.
