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 (710 mm (28 in)), the model 800 (815 mm(32 in)), and the model 900 (915 mm (36 in)). The710 mm (28 in) squeegee is used with the 700model scrub head, as well as the 815 mm (32 in)with the model 800, and the 915 mm (36 in) withthe model 900. The two available brush types aredisk and cylindrical.

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 theindicatorindicator blinks.

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

515700 MP117EN (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% Charged1.223 75% Charged1.185 50% Charged1.148 25% Charged1.110 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.

Deflection is the amount of curl the squeegeeblade has when the machine moves forward withthe squeegee lowered to the floor. The bestdeflection is when the squeegee wipes the floorjust dry with a minimum amount of deflection.


2. Lower the squeegee.

3. Drive the machine forward, and look at thedeflection of the squeegee blade. Thecorrect amount of deflection is 12 mm(0.50 in) for scrubbing smooth floors and15 mm (0.62 in) for rough floors.


5. To adjust the amount of deflection, turn thesqueegee deflection cams counter-clockwiseto decrease the blade deflection.

Turn the squeegee deflection camsclockwise to increase blade deflection.

6. Drive the machine forward again to checkthe squeegee blade deflection.

7. Readjust the squeegee blade deflection ifnecessary.

ADJUSTING THE SQUEEGEE GUIDEROLLERS

At each end of the squeegee are guide rollers toguide the squeegee blade end along a wall.Loosen the nut at the top of the guide roller andmove the roller in or out to adjust how close theend of the squeegee blade comes to the wall. Thesqueegee blade end should be further away fromthe wall when the floor curves up into the wall.

SQUEEGEE BLADES

The squeegee has two squeegee blades, the frontand back. Each blade has four wiping edges. Touse them all, start with one wiping edge. To usethe next wiping edge, rotate the bladeend-for-end. To use the next wiping edge, rotatethe top edges down, bottom edges up. To use thelast edge, rotate the blade end-for-end.

Replace any worn or damaged squeegee blades.

REPLACING OR ROTATING THE REARSQUEEGEE BLADE

1. Make sure the squeegee is raised off thefloor.



3. Loosen the two retention knobs, one at eachend on the squeegee.

BELTS AND CHAINS

BRUSH DRIVE BELT

The two brush drive belts are located on thecylindrical brush scrub head. The belts drive thecylindrical brushes. Proper new belt tension is a 3mm (0.1 in) deflection from a force of 1.37 to 1.48kg (3.0 to 3.26 lb) at the belt midpoint.

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

If the old belt tension was not recorded, therecommended force per old belts is1.03 to 1.14 kg (2.28 to 2.52 lb) with a deflectionof 3 mm (0.1 in).

Check and adjust the belt tension every 100 hoursof operation.

STATIC DRAG CHAIN

A static drag chain prevents the buildup of staticelectricity in the machine. The chain is attached tothe transaxle.

Make sure the chain is always touching the floor.

MAINTENANCE

755700 MP117EN (6--03)

TIRES

The standard front tires are pneumatic.

Check the front tire pressure every 50 hours ofoperation. The proper tire air pressure is415 to 450 kPa (60 to 65 psi).

The front wheel lug nuts should be tightened to102 to 115 Nm (75 to 85 ft lb).

PUSHING AND TRANSPORTING THEMACHINE

PUSHING THE MACHINE

If the machine becomes disabled, it can bepushed if necessary.

Unplug the drive motor from the electrical harnessbefore attempting to push a disabled machine.The machine will become easier to maneuverwhen it is unplugged.

ATTENTION! Do not push the machinefor a long distance and withoutunplugging the drive motor or damagemay occur to the propelling system.

Only push a disabled machine for a very shortdistance and do not exceed 3.2 kp/h (2 mph). It isNOT intended to be pushed for a long distance orat a high speed.
