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 the squeegee,
vacuum motor, float ball filter, recovery tank and
controls. The squeegee wipes 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 two rotary
type disk scrub brushes, motors, scrub deck skirt,
lift 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 and controls are used to raise and
lower the deck.

MACHINE OPERATION
RECOVERY TANK
DOUBLE SCRUB
1. Unhook the large drain hose from the retainer.
Unscrew the T-handle on plug enough to loosen
plug, then lower hose in direction of the drain.
Do not stand in front of end of hose. Recovered
solution will come out with force. Slowly remove
plug from drain hose.
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.
To double scrub, make the first pass over the
surface being cleaned with the squeegee up,
vacuum off, the solution on, Aqua-Mizer removed
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 the
squeegee down and again the solution and brushes
on will further loosen soil. The additional application
of solution will further assist the difficult cleaning job.
2. Remove the recovery tank dome. Flush the
recovery tank out with clean water. Do not use
water hotter than 140°F (60°C) to clean tank.
Damage may occur.
3. Clean off the float shut-off system and inspect
for free movement of float. The float shut-off
system is located in the rear of the recovery
tank.
4. Replace the drain plug and secure drain hose in
bracket.
FOR SAFETY: When using machine, go slow on
inclines and slippery services.

2. SQUEEGEE BLADES
TO REMOVE SQUEEGEE ASSEMBLY
The front squeegee blade allows solution to pass
through channels in the blade into the squeegee
assembly while maintaining vacuum to provide lift.
The front blade has four wear surfaces and can be
rotated for extended life. The front blade should not
require regular replacement under normal use.
1. With the squeegee in the up position, turn key
switch “OFF”.
2. Disconnect vacuum hose from squeegee and
loosen both knobs.
3. Pull squeegee assembly rearward from the
lifting carrier.
4. Inspect or repair as necessary and reinstall.
The rear blade wipes the floor to a near dry
condition. It is important the rear blade be in good
condition to properly do its job. As with the front,
each squeegee blade assembly has four wear
surfaces for extended service.
TO REPLACE OR ROTATE REAR
SQUEEGEE BLADES
1. With the squeegee in the up position, turn key
switch “OFF”.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
2. Remove the squeegee assembly from the
machine. Unlatch and remove blade retainer
strap and remove squeegee blade.
3. Rotate the squeegee to new edge position or
replace as required. Each blade has four new
edge positions.
4. Install blade on locating pins of squeegee
assembly.
5. Install squeegee retainer strap.
6. Fasten and lock latch, adjust latch only tight
enough to take up slack in retaining strap.
Check both the front and rear squeegee blades for
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.
TO REPLACE OR ROTATE FRONT
SQUEEGEE BLADE

2. With the squeegee down, stop the machine. Do
not allow machine to roll back.
FOR SAFETY: Before leaving or servicing the
machine; stop on level surface, turn off machine
and remove key.
3. Determine the differences, if any, in deflection of
the squeegee blade between each end and the
middle. Proper adjustment is obtained when
deflection is equal all the way across the
squeegee blade. The bubble level should also
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, tigthen 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
squeegee and drive forward at least 2 feet
(60cm).
2. With the squeegee down, stop the machine. Do
not allow machine to roll back.
FOR SAFETY: Before leaving or servicing
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

BRUSHES
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. Remove the brush cover shrouds.
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.
5. Replace the brush cover shrouds.
NOTE: Check that release plate is completely
closed and pad/brush is securely attached. Damage
to driver or brush could occur.
FINISHED FLOORS
Nylon bristles are used in a variety of applications
on coated or uncoated surfaces.
5. RECOVERY TANK FLOAT SHUT-OFF
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.
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.
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.
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.
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.
The scrub brushes should be checked before each
days work for wire, string, wear and damage.
4. To install, place one hand on the tube, and
then tilt and push the float screen assembly
over the barb on the tube.
