HOW THE MACHINE WORKS

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

Water and detergent, from the solution tank, flowto the floor through a solution valve to the scrubbrushes. The brushes scrub the floor. As themachine is moved forward the squeegee wipesthe dirty solution off the floor, which is then pickedup and drawn into the recovery tank.

The steering handles control the direction andspeed of the machine in forward or reverse. Byrotating the steering handles forward, the machinepropels forward. By rotating the handles towardsyou the machine propels backward.

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

Three different widths of scrub heads andsqueegees are available for the machine, alongwith two different brush types.

The scrub head widths are as follows; the model700 (700 mm (28 in)), the model 800 (800 mm(32 in)), and the model 900 (900 mm (36 in)). The700 mm (28 in) squeegee is used with the 700model scrub head, as well as the 800 mm (32 in)with the model 800, and the 900 mm (36 in) withthe model 900. The two available brush types aredisk and cylindrical.

OPERATION

215700 MM400 (9--06)

FaST SCRUBBING SYSTEM (OPTION)

The FaST (Foam Scrubbing Technology) systemoperates by injecting the FaST PAK concentrateagent (A) into the system with a small amount ofwater and compressed air. This mixture creates alarge volume of expanded wet foam.

The expanded foam mixture is then dispersedonto the floor (B) while the machine is scrubbing.When the squeegee picks up the mixture, thepatented foaming agent has collapsed and isrecovered into the recovery tank.

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

Using the FaST system can increaseproductivity by 30% by reducing your dump/fillcycle. It will also reduce chemical usage andstorage space. One FaST PAK of concentratedagent can scrub up to 1 million sq. ft.

NOTE: Do not enable the FaST system withconventional cleaning detergents in the solutiontank. Drain, raise and refill the solution tank withclear cool water only before operating the FaSTsystem. Conventional cleaning detergents/restorers may cause failure to the FaST solutionsystem.

NOTE: Storage or transporting machinesequipped with FaST in freezing temperaturesrequires special procedures. Check with aTENNANT representative for advice.

The rear casters each have one grease fitting onthe caster swivel. Lubricate the caster with agrease gun containing Lubriplate EMB grease(TENNANT part no. 01433--1) every 100 hours ofmachine operation.

TRANSAXLE

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

BATTERIES

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

Periodically clean the top surface of the batteriesand the terminals, and check for looseconnections. Use a strong solution of baking sodaand water. Brush the solution sparingly over thebattery tops, terminals, and cable clamps. Do notallow any baking soda solution to enter thebatteries. Use a wire brush to clean the terminalposts and the cable connectors. After cleaning,apply a coating of clear battery post protectant tothe terminals and the cable connectors. Keep thetops of the batteries clean and dry.

MAINTENANCE

555700 MM400 (6--03)

Keep all metallic objects off the top of thebatteries, which may cause a short circuit.Replace any worn or damaged wires.

Check the electrolyte level in each battery cellbefore and after charging, and after every 50hours of operation. Do not charge the batteriesunless the fluid is slightly above the battery plates.If needed, add just enough distilled water to coverthe plates. Never add acid to the batteries. Do notoverfill. Always keep the battery caps on, exceptwhen adding water or taking hydrometer readings.

Measuring the specific gravity, using ahydrometer, is a way to determine the chargelevel and condition of the batteries. If one or moreof the battery cells test lower than the otherbattery cells (0.050 or more), the cell is damaged,shorted, or is about to fail.

NOTE: Do not take readings immediately afteradding distilled water. If the water and acid are notthoroughly mixed, the readings may not beaccurate. Check the hydrometer readings againstthe following chart to determine the remainingbattery charge level:

SPECIFIC GRAVITY BATTERYat 27_ C (80_F) CHARGE

1.265 100% Charged

1.223 75% Charged

1.185 50% Charged

1.148 25% Charged

1.110 Discharged

NOTE: If the readings are taken when the batteryelectrolyte is any temperature other than 27_ C(80_ F), the reading must be temperaturecorrected. Add or subtract to the specific gravityreading 0.004, 4 points, for each 6_ C (10_ F)above or below 27_C (80_ F).

CHARGING THE BATTERIES

1. Drive the machine to a flat, dry surface in awell-ventilated area.

2. Turn the machine power off and set theparking brake if your machine has thisoption.

MAINTENANCE

5700 MM400 (6--03)56


3. Lift up the solution tank to get access to thebatteries.

NOTE: The solution tank must be empty.

4. Check the water level in all the battery cells.

5. If the level is low, add just enough distilledwater to cover the battery plates. DO NOTOVERFILL. The batteries can overflowduring charging due to expansion.

NOTE: Make sure the battery caps are in placewhile charging.

FOR SAFETY: When maintaining orservicing machine, avoid contact withbattery acid.
