HOW THE MACHINE WORKS

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 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 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.

3-3

SABER (QSC) 86037050 01/24/07

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.

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.

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.

MACHINE OPERATION

TO BEGIN SCRUBBING

! CAUTION

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

! WARNING

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

1. Turn the machine power on.

2. Lower the squeegee.

3. Turn the vacuum on.

4. Lower the scrub brush to the floor.

5. Turn the scrub brush on (for traction model,

brush will start when machine is propelled).

6. Drive machine forward to begin scrubbing.

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: For non-traction model, the solution flow must be shut off to prevent unintentional draining of solution tank. For traction model, once solution flow rate is set it is not necessary to shut off solution when stopping scrubbing. Solution flow is automatically shut off when the brush motor stops. When the brush motor is activated, flow will automatically resume.

TO STOP SCRUBBING

1. Release the directional control button(s), if

your machine is traction model.

2. Turn the scrub brush off.

3. Raise the scrub brush.

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 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.

MAINTENANCE

BATTERIES

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.

from the machine and clean the battery cases and battery compartment.

CHECKING BATTERY SPECIFIC GRAVITY

Use a hydrometer to check the battery specific gravity.

Battery Check

CHECKING GRAVITY A. Hydrometer B. Battery

NOTE: Do not take readings immediately after adding distilled water, if the water and acid are not thoroughly mixed, the reading may not be accurate.

MAINTENANCE

Check the hydrometer readings against this chart.

1.225 75% CHARGED

1.190 50% CHARGED

1.155 25% CHARGED

1.120 DISCHARGED

NOTE: If the readings are taken when the battery electrolyte is any temperature other than 80°F (27°C), the reading must be temperature corrected.

To find the corrected specific gravity reading when the temperature of the battery electrolyte is other than 80°F (27°): Add (+) to the specific gravity reading 0.004 (4 points), for each 10°F (6°C) above 80° (27°C). Subtract (-) from the specific reading 0.004 (4 points), for each 10°F (6°C) below 80°F (27°C).

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 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.

UNCOATED FLOORS

Aggressive Grit is a nylon fiber impregnated with

silicone carbide grit. It grinds away stain, soil, and removes surface material.

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.

Nylon is a general-purpose scrub brush with stiff bristles. Polypropylene works well for maintaining concrete, wood and tile floors.

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.

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.

SABER (QSC) 86037050 01/24/07

MAINTENANCE

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.

REPLACING OR INSTALLING SCRUB BRUSHES

1. With the scrub deck up, turn the machine power

off.

FOR SAFETY: Before leaving or servicing the machine; stop on level surface, turn OFF machine and remove key.

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.

3. To reinstall, center the brush drive r un der the brush drive hub. Raise until it contacts brush driver assembly. Turn clockwise until release lever plate locks into position.

NOTE: Check that release plate is completely closed and pad/brush is securely attached. Damage to driver or brush could occur.

SQUEEGEE BLADES

The front squeegee blade allows solution to pass through channels in the blade into the squeegee assembly while maintaining vacuum to provide lift.

The rear blade wipes the floor to a near dry condition. It is important the rear blade be in good condition to properly do its job.

Check both the front and rear squeegee blades for damage and wear each day in the pre-run check. Change the front blade if it is torn or has an uneven edge. Change the rear blade if it is less than 1/2 the original thickness.

TO REMOVE SQUEEGEE ASSEMBLY

1. With the squeegee in the u p position, turn the

machine power off.

2. Loosen both squeegee knobs and pull squeegee assembly rearward from the lifting carrier.

3. Inspect or repair as necessary and rein stall.

TO REPLACE SQUEEGEE BLADES

1. With the squeegee in the u p position, turn the

machine power off.

FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key.

2. Remove the squeegee assembly from the machine. Remove all screws and remove blade retainer strap and remove squeegee blade.

3. Replace squeegee blades as required.

4. Install blade with ribbed surface facin g out.

5. Install squeegee retainer strap.

6. Install all screws starting from center and

working to ends.

DELUXE SQUEEGEE BLADES

The front squeegee blade allows solution to pass through channels in the blade into the squeegee assembly while maintaining vacuum to provide lift. The front blade has four wear surfaces and can be rotated for extended life. The front blade should not require regular replacement under normal use.

The rear blade wipes the floor to a near dry condition. It is important the rear blade be in good condition to properly do its job. Each rear squeegee blade has four wear surfaces for extended service.

Check both the front and rear squeegee blades for damage, wear, and adjustment each day in the prerun check. Change the front blade if it is torn or has an uneven edge. Change the rear blade if it is less than 1/2 the original thickness.

ADJUSTING DELUXE SQUEEGEE

Adjusting the squeegee is a two-part process. First, the squeegee assembly must have correct pitch in order for the squeegee blade to have the same deflection at each tip as well as the center. The knob on the squeegee linkage controls the pitch adjustment. The second adjustment is the deflection.

TO ADJUST SQUEEGEE PITCH

1. Choose a smooth, level surface. Turn “ON” the

key switch and vacuum switch. Lower th e squeegee and drive forward at least 2 feet (60cm.).

2. With the squeegee d own, stop the machine. Do not allow machine to roll back.

FOR SAFETY: Before leaving or servicing the machine, stop on level surface, turn off machine and remove key.

3. Determine the differences, if any, in deflection of

the squeegee blade between each end and the middle. Proper adjustment is obtained when deflection is equal all the way across the squeegee blade.

4. To decrease the deflection of the squeegee blade at the ends, adjust plastic knobs at the far right or left of squeegee assembly.

5. Check the de flection of the squeegee blades again. Repeat steps 1 through 4 until the deflection is equal across the entire rear squeegee blade.

TO ADJUST AMOUNT OF REAR SQUEEGEE DEFLECTION

1. Choose a smooth, level surface. Turn “ON” the

key switch and vacuum switch. Lower th e squeegee and drive forward at least 2 feet (60cm.).

2. With the squeegee d own, stop the machine. Do not allow machine to roll back.

FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine and remove key.

3. Observe the amount of squeegee deflection. It

should deflect approximately 3/8 in. (9.5mm) across the entire width of the squeegee.

4. To increase t he squeegee deflection, turn the center knob above the lift carrier bracket clockwise. To decrease the deflection, turn the knob counterclockwise.

NOTE: The deflection should be consistent along the length of the squeegee. If the deflection varies from end to end the knobs can be adjusted independently to correct the variation.

5. Turn on the key switch. Raise, then lower squeegee assembly. Drive forward at least 2 feet (60cm).

6. Repeat steps 2 through 4 until deflection of approximately 3/8 in. (9.5mm) is reached.
