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 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.
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. Thebrush lift mechanisms are
controls used to raise and lower the deck.
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 goingto 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 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/potentiom-
eter, 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 direction, and at the speed, desired.

4. Apply brakes, if your machine is equipped with this
option.
Filling Solution Tank
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
1. Turn the machine power off.
2. Set the parking brake if your machine is equipped
with this option.
3. Remove solution tank cover.
4. Fill the solution tank with clean water, leaving
enough room for the required amount of cleaning
solution. The solution tank capacity filled to 2” (5
cm) from bottom of fill inlet is 23 gallons (87 liters).
The water must not be hotter than 140° F (60°C) to
prevent damage to the tank.
5. Measure the chemical into the solution tank. Liquid
chemicals should be added to the solution tank
after filling with water. Dry chemicals should be
thoroughly mixed before being added into solution
tank. Commercially available, high alkaline floor
cleaners, are suitable for use in the solution
system.
NOTE: Read the chemical manufacturers
recommended proportion instructions.
6. Replace solution tank cover.
Flammable materials can cause an explosion or
fire. Do not use flammable materials in the tanks.
Les matières inflammables peuvent provoquer une
explosion ou un incendie. Ne pas utiliser de
matériaux inflammables dans les réservoirs.

Operations
Normal Scrubbing
Plan the scrubbing pattern in advance. The longest
track is around the perimeter of the area to be cleaned.
For efficient operation, the runs should be the longest
possible without turning, stopping, or raising and
lowering scrub deck/squeegee.
NOTE: In order to achieve the best possible results,
the area which is to be cleaned should be swept
before scrubbing. Large debris, strings & wire must
be removed to prevent being caught in brushes or
squeegee.
To Begin Scrubbing
When operating the machine around people, pay
close attention for unexpected movement. Use
extra caution around children.
Lorsque vous utilisez la machine en présence de
gens, portez une attention particulière aux mouve-
ments inattendus. Soyez plus prudent, surtout en
présence d’enfants.
Flammable liquids and/or reactive metals can
cause explosions or fire! Do not pick up.
Les liquides inflammables et / ou les métaux
réactifs peuvent provoquer des explosions ou un
incendie ! Ne les ramassez pas.
1. Turn the machine power on.
2. Lower the squeegee.
3. Turn the vacuum on.
4. Lower the scrub brushes to the floor.
5. Turn the scrub brushes on (brushes will start when
machine is propelled).
6. Drive machine forward to begin scrubbing.
NOTE: Shut machine off immediately if water or foam
is expelled from the machine.
7. Adjust the speed of the machine, solution flow and
scrub brush pressure as necessary.
NOTE: Once solution flow rate is set it is not
necessary to shut off solution when stopping
scrubbing. Solution flow is automatically shut off
when brush motors stop. When brush motors are
activated, flow automatically resumes.
To Stop Scrubbing
1. Release the propel levers.
2. Turn the scrub brushes off.
3. Raise the scrub brushes.
4. Raise the squeegee.
5. Turn the vacuum off.
6. Turn the machine power off.

Operations
Double Scrub
For floors which are heavily soiled or have thick accu-
mulations 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.
FOR SAFETY: When using machine, go slow on
inclines and slippery services.
Emptying And Cleaning Tanks
1. Park the machine next to a floor drain. Drain hose
is on left rear corner of the machine.
2. Turn the machine power off and set parking brake,
if your machine is equipped with this option.
Solution Tank
1. Loosen small drain hose from the retainer, then
lower hose in direction of the drain.
2. Remove the solution tank cover.
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.
4. Secure drain hose into the retainer.
Recovery Tank
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.
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.
5. If machine is to be stored, leave the recovery tank
dome off.
