HOW THE MACHINE WORKS

The Saber Glide is a battery powered, selfpropelled, 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 operator 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 switch 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 disk scrub systems consists of two rotary type disk scrub brushes, motors, scrub deck skirt, lift actuator and controls. The brushes scrub the floor as 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 scrub deck skirts and side squeegees control the cleaning solution on the floor so that the squeegee can pick it up. The one touch 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.

3-3

SGJ32 86037680 01/03/07

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, 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, shuts off the scrub motors and solution flow, raises the scrub deck then squeegee, and shuts off vacuum motor.

The function of the operator control system is to control the direction and speed of the machine. The directional control system consists of the direction/speed control pedal, steering wheel, brake pedal, propel controller, and drive wheel. The direction/speed pedal signals forward or reverse direction and speed. The controller interprets signals from the direction/speed pedal to command the drive wheel to propel or slow the machine. The steering wheel points the drive wheel in the direction desired by the operator. The brake can be used to hold the machine on slopes.

problems that could cause poor performance or lost time from breakdown. Follow the same procedure each time to avoid missing steps.

Visually check for exterior damage, leaks,

damaged or worn tires.

2. Check brushes or pads an d drivers for proper installation and wear. Weekly check scrub deck skirts for proper contact with floor. See BRUSHES in MAINTENANCE SECTION.

3. Check squeegee for wear and proper adjustment. See SQUEEGEE ADJUSTMENT in MAINTENANCE SECTION.

4. Check for securely attached drain hose, plug, and caps.

5. Check battery condition, recharge if necessary. See BATTERIES in maintenance section.

6. Check the brakes and steering for pro per operation. See BRAKES and STEERING in MAINTENANCE SECTION.

STARTING MACHINE

NOTE: Perform pre-run machine check before operating machine.

FOR SAFETY: Before starting machine, make sure that all safety devices are in place and operating properly.

1. The operator should be in the seat with the right

foot on the brake pedal or with the parking brake on. The directional pedal must be in the neutral position to avoid unintentional movement.

NOTE: The Operator must be in position on the seat to activate machine in desired direction.

2. Turn the key switch clockwise to the “ON” position.

3. Release the brake, then press lightly on the

directional pedal in the desired direction and drive to the filling area.

FILLING THE MACHINE

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

1. Set squeegee and scrub deck to up position, set parking brake, and turn off key switch.

2. Remove solution tank cover.

! WARNING

Do not use flammable materials in the tanks.

Flammable materials can cause an explosion or fire.

SGJ32 86037680 01/03/07

MACHINE OPERATION

The solution tank can be filled to the FULL

marking of the fill inlet. Leave room for detergent. The solution tank capacity is 30 gallons (114 liters). The water must not be hotter than 140' (60'C) to prevent damage to the tank. Measure the required amount of chemical into the solution tank after filling with water. Dry chemicals should be thoroughly mixed before being added into solution tank. Commercially available, high alkaline floor cleaners are suitable for use in the solution system.

4. Inspect solution tank cover vent for obstructions.

Replace solution tank cover.

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 or lowering scrub deck/squeegee.

In order to achieve the best possible results, the area which is to be cleaned should be swept before scrubbing. Large debris, strings and wire must be removed to prevent being caught in brushes or squeegee.

The machine will automatically raise the squeegee slightly when reverse travel is selected. If the machine is allowed to stand in neutral with the scrub deck down for more than 2 seconds, the solutions flow stops and brush motors stop. If either forward or reverse travel is selected, the solution flow will continue in the same setting and the scrub brush motors will continue in their same setting once movement of machine begins. Overlap the brush path and avoid transporting over previously cleaned areas.

EMERGENCY STOP PROCEDURE

1. Turn key switch to off position. If an electrical

problem is suspected push in emergency stop button.

2. Release pressure on directional pedal.

3. Apply brakes.

NOTE: Turning the key switch off during normal running operation will stop all motors and actuators. When the key is turned back on the system will automatically return scrub deck and squeegee to raised position.

DOUBLE SCRUB

Floors which are heavily soiled or have thick accumulation of floor finish 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, the solution on, and brushes down. This allows the solution to stay in contract with the soil while loosening the surface accumulation with the brushes. Allow time for the first application to stay in contact with floor. Length of time between the first and second pass depends on amount of accumulation and the type of chemical being used. A second scrubbing with the squeegee down and again the solution and brushes on will further loosen soil. The additional application of solution will further assist the difficult cleaning job. Caution should be used when double scrubbing, maintain safe driving speed on wet floors.

1. BATTERIES

The batteries provide the power to operate the machine. The batteries require regular maintenance to keep them operating at peak efficiency. 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 case. Do not operate the machine if the batteries are in poor condition or if they have a charge level below 25%, specific gravity below 1.177. 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 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.

4. SCRUB BRUSHES

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 machine. 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 bristles are used in a variety of applications

on coated or uncoated surfaces. Polypropylene bristles work on a variety of floor

surfaces. Does not soften in water 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.

MAINTENANCE

REPLACING OR INSTALLING SCRUB BRUSHES

4. With actuator fully retracted, turn barrel in until it touches the base of the threaded shaft.

5. At the bottomed out position, turn the barrel out 3 full turns, then enough to allow connection to lift linkage.

6. Connect actuator to lift linkage and check that in the raised/retracted position the stops on the scrub deck barely touch the rubber bumpers on the frame.

NOTE: If further adjustment is needed, disconnect the actuator from scrub deck lift linkage and turn the barrel one half-turn at a time in to make scrub deck stops closer to bumpers, or out to eliminate excessive pressure against bumpers.

TRANSPORTING MACHINE

TOWING OR PUSHING MACHINE

The machine may be towed for short distances at speeds not to exceed 5 mph. Be careful to avoid damaging machine. Attach towing device at tie down point. The machine may be pushed by hand from the rear.

NOTE: To avoid damage caused by regenerative voltage, disconnect traction motor before towing or pushing machine.

MACHINE TIE-DOWNS

There are two tie points located at the rear, side of the machine frame and two at the front corners. Tiedown devices must be of the proper type and strength. The combined strength of all tie-downs must be strong enough to lift two times the weight of the machine. Tie-downs must be positioned to prevent the machine from moving forward, backward, or either side to side. Use all four corners of the machine with the tie-downs running out opposite directions. Tie-downs must be attached to the transporting vehicle securely.
