HOW THE MACHINE WORKS

The Saber SX 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. There are two types of scrub systems
available – disk and cylindrical.
The disk scrub system consists of two rotary type
disk scrub brushes, motors, self-adjusting scrub
deck skirt, lift actuator 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 the floor. The self-
adjusting scrub deck skirt controls the cleaning
solution on the floor so that the squeegee can
pick it up. The brush motor/lift switch controls the
motors and lift actuator to turn the motors on and
lower the deck, or turn the motors off and raise
the deck. The brush pressure switch controls the
down pressure on the scrub deck.
The cylindrical scrub system consists of two rotary
cylindrical scrub brushes, motors, debris hopper,
lift actuator and controls. The cylindrical scrub
head is designed to eliminate debris that may be
caught in the squeegee while scrubbing. The
brushes scrub the floor and throw debris into the
hopper. The motors drive the brushes. The
brush motor/lift switch controls the motors and lift
actuator to turn the motors on and lower the deck,
3-3
or turn the motors off and raise the deck. The
brush pressure switch controls the down pressure
on the scrub 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, 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 filter
protects the vacuum fan from debris and foam.
The recovery tank stores the dirty solution. The
float switch in the tank activates the recovery tank
full indicator and shuts off the vacuum motor.
The function of the directional control system is to
control the direction and speed of the machine.
The directional control system consists of the
directional control lever, switches, speed control
knob/potentiometer, controller and transaxle. The
directional control lever actuates switches, which
signal forward or reverse. 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.
