HOW THE MACHINE WORKS

The following machine components work togetherto effectively clean dirty floors: Pre--Sweep(option) or side brush (option), solution tank,scrub brushes, squeegee, vacuum fan, andrecovery tank.

The Pre--Sweep (option) and the side brush(option) sweep up light debris in the path of themachine.

Water and detergent from the solution tank flow tothe floor through a solution valve. The brushesuse the detergent and water solution to scrub thefloor clean. As the machine propels forward, thesqueegee wipes the dirty solution from the floor.The suction created by the vacuum fan thendraws the dirty solution from the squeegee intothe recovery tank.

The directional pedal controls the speed anddirection of the machine. The brake pedal slowsand stops the machine.

When using the ES mode (option), the dirtysolution in the recovery tank is filtered andreturned to the solution tank to be reused forextended scrubbing.

The two available scrub head types use disk orcylindrical brushes.

NOTE: The amount and type of soilage play animportant role in determining the type of brushesto be used. For specific recommendations,contact your Tennant representative.

FaST SCRUBBING SYSTEM

Unlike conventional scrubbing, the FaST (FoamScrubbing Technology) system operates byinjecting the FaST PAK concentrate agent into thesystem with a small amount of water andcompressed air. This mixture creates a largevolume of expanded wet foam.

The expanded foam mixture is then dispersedonto the floor 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, rinse 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.

BATTERIES

The batteries are designed to hold their power forlong periods of time. The lifetime of the batteriesis limited to number of charges the batteriesreceive. To get the most life from the batteries,recharge them immediately when the batterydischarge indicator begins to blink.

After every 200 hours of use check for loosebattery connections and clean the surface of thebatteries, 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 thebatteries. Use a wire brush to clean the terminalposts and the cable connectors. Wipe off allcleaning solution residue. After cleaning, apply acoating of clear battery post protectant to theterminals and the cable connectors. Keep the topsof the batteries clean and dry.

Objects made of metal can potentially short circuitthe batteries. Keep all metallic objects off thebatteries. 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.

Using a hydrometer, measure the specific gravityto determine the charge level and condition of thebatteries. If one or more of the battery cells testlower than the other battery cells (0.050 or more),the cell is damaged, shorted, or is near failure.Completely recharge the batteries, then retestthem.

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:

BELTS AND CHAINS

SCRUB BRUSH DRIVE BELTS

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.

PRE--SWEEP BRUSH MOTOR BELT (OPTION)

The Pre--Sweep brush motor belt is located insidethe Pre--Sweep assembly on the right hand sideof the cylindrical brush. The belt drives the brushdrive belt sheave. Proper belt tension is a 3 mm(0.12 in) deflection from a force of 0.6 to 0.64 kg(1.3 to 1.4 lb) at the belt midpoint.

Check the belt tension and wear every 100 hoursof operation.

PRE--SWEEP BRUSH DRIVE BELT (OPTION)

The Pre--Sweep brush drive belt is located insidethe Pre--Sweep assembly on the right side of thecylindrical brush. The belt drives the cylindricalbrush. Proper belt tension is a 2 mm (.08 in)deflection from a force of 0.76 to 0.8 kg (1.7 to 1.8lb) at the belt midpoint.

Check the belt tension and wear every 100 hoursof operation.

STATIC DRAG CHAIN

The static drag chain prevents the buildup ofstatic electricity in the machine. The chain isattached to the rear squeegee mounting channel.

Make sure the chain is always touching the floor.

STEERING GEAR CHAIN

The steering gear chain is located directly abovethe front tire.

The steering gear chain tension should bechecked after the first 50 hours of operation andevery 500 hours thereafter. The proper deflectionshould be 3 to 6 mm (0.1 to 0.3 in) between thesteering sprocket and the idler sprocket when thesteering wheel is turned as far as it will go ineither direction.
