HOW THE MACHINE WORKS
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, screen, 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 screen protects the vacuum fan from debris.
The recovery tank stores the dirty solution. The
float ball in the tank activates when the recovery
tank is full.
The Saber Compact is a battery powered, hard
floor scrubber intended for commercial use. The
appliance applies a cleaning solution onto a hard
floor, scrubs the floor with a brush, and then
vacuums the soiled water back into the recovery
tank.
The machine's primary systems are the solution
system, scrub system, recovery system. The
traction model has a directional control system as
well.
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
non-traction model has a ball-type valve which
controls the delivery of cleaning solution to the
scrub system. The traction model has a solenoid
type valve, which controls the delivery of cleaning
solution to the scrub system. The valve
On the traction model, the function of the
directional control system is to control the
direction and speed of the machine. The
directional control system consists of buttons,
speed control knob/potentiometer, controller and
transaxle. The speed control knob actuates a
potentiometer, which signals speed. The
controller interprets the forward/reverse signals
from the buttons and the speed signal from the
potentiometer to command the transaxle to propel
the machine in the direction, and at the speed,
desired.
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.
The buttons on the control handles signal forward.
When the reverse button on the control panel is
pushed, in addition to either button on the control
handles, reverse is signaled.
The function of the scrub system is to scrub the
floor. The scrub system consists of a rotary type
disk scrub brush, motor, self-adjusting scrub deck
skirt, lift linkage and controls. The brush scrubs
the floor and the motor drives the brush. The
brush drive hub allows the scrub brush to follow
irregularities and changes in the floor without
loosing contact with floor. The self-adjusting
scrub deck skirt controls the cleaning solution on
the floor so that the squeegee can pick it up. The
brush lift lever raises and lowers the scrub deck.
On the traction model the brush lift lever can be
locked into an increased brush pressured
position.

SCRUB BRUSHES
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.
NOTE: All original equipment brushes are equipped
with “Perform Alert©”. This feature will tell the
operator when it is time to replace the scrub brush.
“Perform Alert©” brushes have pre-trimmed bright
yellow tufts to indicate the length of a worn out
brush. When the tufts in the scrub brush wear to a
length equal to the yellow tufts, the scrub brush
should be replaced.
Brown 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.
There are five 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
and further add to the flexibility of the Saber
Compact. Please refer to the following to assist in
selecting the proper brush or pad for the work at
hand.
The scrub brush should be checked before each
days work for wire, string, wear and damage. The
scrub brush should be replaced if brush bristles are
missing or if yellow Perform Alert © indicates
minimum brush length.
REPLACING OR INSTALLING SCRUB
BRUSHES
UNCOATED FLOORS
1. With the scrub deck up, turn the machine power
off.
Aggressive Grit is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
FOR SAFETY: Before leaving or servicing the
machine; stop on level surface, turn OFF
machine and remove key.
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.
2. 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.
Nylon is a general-purpose scrub brush with stiff
bristles. Polypropylene works well for maintaining
concrete, wood and tile floors.
3. 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.
FINISHED FLOORS
Nylon Polish is the softest brush. It will gently clean
finished tile or terrazzo floors without removing floor
finish or floor material. Used for washing highly
polished or burnished floors.
NOTE: Check that release plate is completely
closed and pad/brush is securely attached. Damage
to driver or brush could occur.
Nylon bristles are used in a variety of applications
on coated or uncoated surfaces.
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.
