Operations
Special Notes:
The sound pressure level at the operator’s ear was measured to be 75 dBA. This was a nearfield, broad-band
measurement taken in a typical industrial environment on a tile floor. This appliance contains no possible source of
impact noise. The instantaneous sound pressure level is below 63 Pa.
The weighted root mean square acceleration at the operator’s arms was measured to be below 2.5m/s2. This was
a tri-axial, third-octave-band measurement made during normal operation on a composite tile floor. The measure-
ment and related calculations were made in accordance with ANSI S3.34-1986.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.

Operations
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.
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 tothe 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.
