HOW THIS MACHINE WORKS

This Automatic Scrubber 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 and recovery 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, and valve. 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 machine has a ball-type valve
which controls the amount of cleaning solution
delivered to the scrub system. The solenoid type
valve controls the delivery of cleaning solution to the
scrub system. The valve automatically prevents
solution flow unless the scrub brushes are turned
on. The solution control lever controls the amount of
cleaning solution delivered to the scrub system.

3-3

86221970 17” SCRUBBER 01/03/07

The function of the scrub system is to scrub the
floor. The scrub system consists of a rotary type
disk scrub brush, motor, and lift linkage. The brush
scrubs the floor and the motor drives the brush. The
brush lift lever raises and lowers motor and brush.

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, and recovery tank. 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.

MACHINE OPERATIONS

PRE-RUN MACHINE INSPECTION

Do a pre-run inspection to find possible problems
that could cause poor performance or lost time from
breakdown. Follow the same procedure each time to
avoid missing steps.

NOTE: See maintenance section for pre-run
machine inspection checklist items.

FILLING SOLUTION TANK
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine.

1. Turn the machine off.

2. Remove solution tank cover.

3. Fill the solution tank with clean water, leaving

enough room for the required amount of
cleaning solution. The solution tank capacity is
8 gallons (30.3 liters). The water must not be
hotter than 140° F (60°C) to prevent damage to
the tank.

4. 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 the solution tank. Commercially available,
high alkaline floor cleaners are suitable for use
in the solution system.

NOTE: Read the chemical manufacturers
recommended proportion instructions.

5. Replace solution tank cover.

Flammable materials can cause an explosion or
fire. Do not use flammable materials in the
tanks.

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 brush/squeegee.

NOTE: In order to achieve the best possible results,
the area that is to be cleaned should be swept
before scrubbing. Large debris, strings & wire mu st
be removed to prevent being caught in the brush or
squeegee.

3-7

86221970 17” SCRUBBER 01/03/07

MACHINE OPERATION

TO BEGIN SCRUBBING

When operating the machine around people, pay
close attention for unexpected movement. Use
extra caution around children.

Flammable liquids and/or reactive metals can
cause explosions or fire! Do not pick up.

1. Lower the squeegee.

2. Turn the vacuum on.

3. Lower the scrub brush to the floor.

4. Turn the scrub brush on.

5. Push machine forward to begin scrubbing.

NOTE: Shut machine off immediately if water or
foam is expelled from the machine.

6. Adjust the solution flow as necessary.

TO STOP SCRUBBING

1. Turn the scrub brush off.

2. Raise the scrub brush.

3. Raise the squeegee.

4. Turn the vacuum off.

DOUBLE SCRUB
For floors, which are heavily soiled or have thick
accumulations of floor finish the machine 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,
and brush down and on. This allows the solution to
stay in contact with the soil while loosening the
surface accumulation with the brush. Allow time for
the first application to stay in contact with the floor.

The length of time between the first and second
pass depends on the amount of accumulation and
the type of chemical being used. A second
scrubbing with the squeegee down, vacuum on and
again with solution and brush on will further loosen
the 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 drain. Drain hoses

are on the rear of the machine.

2. Turn the machine off.

SOLUTION TANK

1. Pull the small drain hose from the retainer.

Lower the hose in the 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 the tank, damage may occur.

NOTE: Never allow solution to remain in tank.
Damage to tank, seals and valves could occur.

4. Replace drain hose to retainer.

RECOVERY TANK

1. Unhook the large drain hose from the retainer.

Unscrew the drain cap from the end of the
recovery tank drain hose. Lower the hose in the
direction of the drain. Do not stand in front of the
end of the hose. Recovered solution will come
out with force.

2. Flush the recovery tank out with clean water. Do

not use water hotter than 140°F (60°C) to clean
the tank, damage may occur.

3. Clean off the float and check for free movement

of the float ball.

4. Replace the drain plug and secure the drain

hose in the retainer.

MAINTENANCE

BATTERIES (WET CELL BATTERIES ONLY)

The batteries provide the power to operate the
machine. The batteries require regular maintenance
to keep them operating at peak efficiency.

The machine batteries will hold their charge for long
periods of time, but they can only be charged a
certain number of times. To get the greatest life
from the batteries, charge them when their charge
level reaches 25% of a full charge. Use a
hydrometer to check the charge level.

Do not allow the batteries to remain in a discharged
condition for any length of time. Never expose a
discharged battery to temperatures below freezing.
Discharged batteries will freeze causing cracked
cases. Do not operate the machine if the batteries
are in poor condition or if they have a charge level
below 25% (specific gravity below 1.155).

Keep all metallic objects off the top of the batteries,
as they may cause a short circuit. Replace worn or
damaged cables and terminals.

Check the electrolyte level in each battery cell
before and after charging the batteries. Never add
acid to the batteries, use distilled water. Do not
allow water level to fall below the battery plates.
Portions of plates exposed to air will be destroyed.
Do not overfill. Keep plugs firmly in place at all
times.

When servicing machine, avoid contact with
battery acid.

Batteries emit hydrogen gas. Explosion or fire
can result. Keep sparks and open flame away.
Keep covers open when charging.

Wear eye protection and protective clothing
when working with batteries.

Charge batteries in a well ventilated area.
BATTERY MAINTENANCE

1. When cleaning the batteries, use a solution of

baking soda and water. Do not allow the
cleaning fluid to enter the battery cells,
electrolyte will be neutralized.

2. Maintain the proper electrolyte level in each

battery cell. If a cell should accidentally
overflow, clean immediately.

3. Wipe off the top of the batteries at least once a

week.

4. Test battery condition with a hydrometer at least

once a week.

5. Ensure that all connections are tight and all

corrosion removed.

SCRUB BRUSHES

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.

There are three 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.

UNCOATED FLOORS
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.

Polypropylene is a general-purpose scrub brush

with stiff bristles. Polypropylene works well for
maintaining concrete, wood and tile floors.

FINISHED FLOORS
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.

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.

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.

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.
