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. The brush lever is used to
raise and lower the deck. For heavy scrub pressure
lock the lever into the lower notch. Pushing the lever
forward allows you to push down. Pull Back on the
lever to allow it to swing down and out of the way.
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 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 control
buttons actuates switches, which signal forward
pressing the reverse button in addition to one of the
propel control buttons the machine will move in
reverse. The speed control knob actuates a potentiom-
eter, 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.

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.

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 incontact 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.

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.
