HOW THE MACHINE WORKS

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

With conventional scrubbing, water and detergent,from the solution tank, flow to the floor through asolution valve to the scrub brushes or pads. Thebrushes or pads scrub the floor. As the machinemoves forward, the squeegee wipes the dirtysolution off the floor, which is then picked up anddrawn 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.

Three different widths of scrub heads andsqueegees are available for the machine.

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.

OPERATION

5680 331176 (3--08)18

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 increase productivityby 30% by reducing your dump/fill cycle. It willalso reduce chemical usage and storage space.One FaST PAK of concentrated agent can scrubup 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.

OPERATION

195680 331176 (09--08)

ec-H2O SYSTEM (OPTION)

The ec--H2O (electrically converted water) systemoperates by producing electrically activated waterfor cleaning.

Normal water passes through a module where it isoxygenated and charged with an electric current.The electrically converted water changes into ablended acidic and alkaline solution forming aneutral pH cleaner. The converted water attacksthe dirt, breaks it into smaller particles, and pulls itoff the floor surface allowing the machine to easilyscrub away the suspended soil. The convertedwater then returns to normal water in the recoverytank.

The ec--H2O system can be used with all doublescrubbing applications.

NOTE: Do not enable the ec--H2O system withconventional cleaning detergents in the solutiontank. Drain, raise and refill the solution tank withclear cool water only before operating the ec--H2Osystem. Conventional cleaning detergents/restorers may cause failure to the ec--H2Osolution system.

NOTE: Storage or transporting machinesequipped with ec--H2O in freezing temperaturesrequires special procedures. Check with aTENNANT representative for advice.

LUBRICATION

REAR CASTERS

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 all the batterydischarge indicator segments shut off (20%charge left). Use an automatic charger with theproper rating for the batteries.

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

5680 331176 (9--06)42

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

Never add acid to the batteries, only distilledwater. Always keep the battery caps on, exceptwhen adding water or taking hydrometer readings.

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

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).

SQUEEGEE

The squeegee assembly channels water into thevacuum fan suction. The front blade channels thewater, and the rear blade wipes the floor.

Check the squeegee blades for damage and weardaily. Rotate or replace either of the squeegeeblades if the leading edge is torn or worn half-waythrough the thickness of the blade.

The squeegee can be adjusted for leveling anddeflection. The deflection and leveling of thesqueegee blades should be checked daily, orwhen scrubbing a different type of floor.

The squeegee assembly can be removed fromthe squeegee pivot to prevent damage duringtransport of the machine, or when changing to adifferent squeegee width. The squeegees areavailable in three widths to be used with the threedifferent model scrub heads; model 700 (700 mm(28 in)), model 800 (800 mm (32 in)), and model900 (900 mm (36 in)).

REMOVING THE SQUEEGEE ASSEMBLY

1. Raise the squeegee.



3. Remove the squeegee suction hose fromthe squeegee.

7. Readjust the squeegee blade deflection ifnecessary.

ADJUSTING SQUEEGEE BLADE DEFLECTION

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.

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 the belt tension and wear 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.

TIRES

The standard front tires are foam filled.

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