OPERATION

HOW THE MACHINE WORKS

The scrub components of the machine are a solution tank, scrub brushes, a squeegee, a vacuum fan, and a recovery tank.

Water and detergent, from the solution tank, flow to the floor through a solution valve to the scrub brushes. The brushes scrub the floor. As the machine is moved forward the squeegee wipes the dirty solution off the floor, which is then picked up and drawn into the recovery tank.

The steering handles control the direction and speed of the machine in forward or reverse. By rotating the steering handles forward, the machine propels forward. By rotating the handles towards you the machine propels backward.

When using the ES mode, the dirty solution in the recovery tank is filtered and returned to the solution tank to be reused.

NORMAL SCRUBBING

D

Pick up oversized debris before scrubbing.

Pick up pieces of wire, string, twine, etc., which could become wrapped around the scrub brush.

D

Plan the scrubbing in advance. Try to arrange long runs with minimum stopping and starting. Do an entire floor or section at one time.

D

Try to scrub as straight a path as possible.

Avoid bumping into posts or scraping the sides of the machine. When scrubbing dead end aisles, start at the closed end of the aisle and scrub your way out. Overlap the scrub paths by a few centimeters (inches).

D

If you see poor scrubbing performance, stop scrubbing and refer to MACHINE

TROUBLESHOOTING.

Non-scuff polypropylene scrub brush -- This brush uses a softer, general purpose polypropylene bristle to lift lightly compacted soilage without scuffing high-gloss coated floors.

Nylon scrub brush -- Recommended for scrubbing coated floors. Cleans without scuffing.

LUBRICATION

REAR CASTERS

The rear casters each have one grease fitting on the caster swivel. Lubricate the caster with a grease gun containing Lubriplate EMB grease

(TENNANT part no. 01433--1) every 100 hours of machine operation.

TRANSAXLE

Check the transaxle lubricant level every 1000 hours of operation by removing one of the orange filler plugs. If needed, add SAE 90 weight gear lubricant.

BATTERIES

The batteries are unique in that they hold their power for long periods of time. The lifetime of the batteries is limited by the number of charges the batteries receive. To get the most life from the batteries, charge them when the battery discharge indicator’s needle remains in the red zone of the indicator.

Periodically clean the top surface of the batteries and the terminals, and check for loose connections. Use a strong solution of baking soda and water. Brush the solution sparingly over the battery tops, terminals, and cable clamps. Do not allow any baking soda solution to enter the batteries. Use a wire brush to clean the terminal posts and the cable connectors. 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.

46

5700EE 3315353 (9--06)

Keep all metallic objects off the top of the batteries, which may cause a short circuit.

Replace any worn or damaged wires.

Check the electrolyte level in each battery cell before and after charging, and after every 50 hours of operation. Do not charge the batteries unless the fluid is slightly above the battery plates.

If needed, add just enough distilled water to cover the plates. Never add acid to the batteries. Do not overfill. Always keep the battery caps on, except when adding water or taking hydrometer readings.

Measuring the specific gravity, using a hydrometer, is a way 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 about to fail.

NOTE: Do not take readings immediately after adding distilled water. If the water and acid are not thoroughly mixed, the readings may not be accurate. Check the hydrometer readings against the following chart to determine the remaining battery charge level:

BELTS AND CHAINS

BRUSH DRIVE BELT

The two brush drive belts are located on the cylindrical brush scrub head. The belts drive the cylindrical brushes. Proper new belt tension is a 3 mm (0.1 in) deflection from a force of 1.37 to 1.48

kg (3.0 to 3.26 lb) at the belt midpoint.

When reusing an old belt, measure and record the belt tension before removal, so that the belt can be reinstalled at the same tension.

If the old belt tension was not recorded, the recommended force per old belts is

1.03 to 1.14 kg (2.28 to 2.52 lb) with a deflection of 3 mm (0.1 in).

Check the belt tension and wear every 100 hours of operation.

STATIC DRAG CHAIN

A static drag chain prevents the buildup of static electricity in the machine. The chain is attached to the transaxle.

Make sure the chain is always touching the floor.

MAINTENANCE

5700EE 331535 (9--06)
