OPERATION

HOW THE MACHINE WORKS

The machine solution tank, scrub brushes, squeegee, vacuum fan, and recovery tank work together to effectively clean dirty floors.

Water and detergent from the solution tank flow to the floor through a solution valve. The brushes use the detergent and water solution to scrub the floor clean. As the machine propels forward, the squeegee wipes the dirty solution from the floor.

The suction created by the vacuum fan then draws the dirty solution from the squeegee into the recovery tank.

The steering wheel controls the path of the machine travel. The directional switch controls the forward or reverse direction of the machine. The propel pedal controls the speed of the machine.

The brake pedal slows and stops the machine.

The buttons on the control panel control the machine scrubbing functions. The One Step

Scrub button turns the preset scrub functions on and off. The FaST button controls use of the

Foam scrubbing system. The vacuum fan /

squeegee button turns the vacuum fan on/off and raises and lowers the squeegee. The brush

pressure buttons control the scrub brush pressure, and the solution buttons control the solution flow.

There are two different types of scrub heads available, cylindrical and disk. Both scrub heads are available in two different widths. The Disk scrub head is available in 650 mm (26 in) wide and

800 mm (32 in) wide. The Cylindrical scrub head is available in 700 mm (28 in) wide and 800 mm (32 in) wide.

NOTE: The amount and type of soilage play an important role in determining the type of brushes or pads to use. For specific recommendations, see the BRUSH INFORMATION section of this manual or contact a Tennant representative.

FOAM SCRUBBING SYSTEM (FAST MODE)

Unlike conventional scrubbing, the optional FaST

(Foam Scrubbing Technology) system operates by injecting the FaST--PAK concentrate agent into the system with a small amount of water and air.

This mixture creates a large volume of expanded wet foam.

The expanded foam mixture is then dispersed onto the floor while the machine is scrubbing.

When the squeegee picks up the mixture, the patented foaming agent has collapsed and is recovered into the recovery tank.

The FaST system can be used with all double scrubbing and heavy duty scrubbing applications.

Using the FaST system improves safety and can increase productivity by 30% by reducing your dump/fill cycle. It will also reduce chemical usage and storage space. One FaST--PAK of concentrated agent can scrub up to 90,000 m 2 million square feet).

(1

NOTE: Do not use the FaST system with conventional cleaning detergents in the solution tank. Drain, rinse and refill the solution tank with clear cool water before operating the FaST system. Conventional cleaning detergents may cause failure to the FaST system.

OPERATION

CIRCUIT BREAKERS

Circuit breakers are resettable electrical circuit protection devices that stop the flow of current in the event of a circuit overload. Once a circuit breaker is tripped, allow breaker to cool and then press the reset button to manually reset the breaker.

FUSES

The fuse is a one-time protection device designed to stop the flow of current in the event of a circuit overload. The 100 A fuse is located inside the battery compartment near the hourmeter. It protects the propel circuit.

NOTE: Always replace the fuse with a fuse of the same amperage.

If the overload that caused the circuit breaker to trip is still there, the circuit breaker will continue to stop current flow until the problem is corrected.

The circuit breakers are located inside the battery compartment next to the hour meter.

The chart shows the circuit breakers and the electrical components they protect.

MAINTENANCE

BATTERIES

The batteries are designed to hold their power for long periods of time. The lifetime of the batteries is limited to number of charges the batteries receive. To get the most life from the batteries, recharge them immediately when the battery discharge indicator begins to blink.

LEAD ACID BATTERIES

Check the electrolyte level in each battery cell before and after charging, and after every 50 hours of operation. Never add acid to the batteries. Add distilled water only. Always keep the battery caps on, except when adding water or taking hydrometer readings.

FOR SAFETY: When servicing machine, wear protective gloves when handling batteries or battery cables. Avoid contact with battery acid.

After every 200 hours of use check for loose battery connections and clean the surface of the batteries, including terminals and cable clamps, using a strong solution of baking soda and water.

Brush the solution sparingly over the battery tops.

Do not allow any baking soda solution to enter the batteries. Use a wire brush to clean the terminal posts and the cable connectors. Wipe off all cleaning solution residue. After cleaning, apply a coating of clear battery post protectant to the terminals and the cable connectors. Keep the tops of the batteries clean and dry.

Objects made of metal can potentially short circuit the batteries. Keep all metallic objects off the batteries. Replace any worn or damaged wires.

Replace any defective batteries. To dispose of batteries, contact a battery dealer or your Tennant

Service representative.

GEL BATTERIES

The Gel batteries are maintenance free and do not need to have the electrolyte level checked.

Using a hydrometer, measure the specific gravity to determine the charge level and condition of the batteries. If one or more of the battery cells test lower than the other battery cells (0.050 or more), the cell is damaged, shorted, or is near failure.

Completely recharge the batteries and then retest.
