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.

The buttons on the control panel control themachine scrubbing functions. The One StepScrub button turns the preset scrub functions onand off. The FaST button (option) enables theFaST (Foam Scrubbing Technology) system. Theec−H2O button (option) enables the ec−H2O(electrically converted water) system. Thevacuum fan / squeegee button turns the vacuumfan on/off and raises and lowers the squeegee.The brush pressure buttons control the scrubbrush pressure, and the solution buttons controlthe solution flow.

The steering wheel controls the path of themachine travel. The directional switch controls theforward or reverse direction of the machine. Thepropel pedal controls the speed of the machine.The brake pedal slows and stops the machine.

There are two different types of scrub headsavailable, cylindrical and disk. Both scrub headsare available in two different widths. The Diskscrub head is available in 650 mm (26 in) wide and800 mm (32 in) wide. The Cylindrical scrub head isavailable in 700 mm (28 in) wide and 800 mm (32 in) wide.

NOTE: The amount and type of soilage play animportant role in determining the type of brushesor pads to use. For specific recommendations,see the BRUSH INFORMATION section of thismanual or contact a Tennant representative.

CONVENTIONAL SCRUBBING

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.

FOAM SCRUBBING SYSTEM (FaST MODEL)

Unlike conventional scrubbing, the optional FaST(Foam Scrubbing Technology) system operatesby injecting the FaST−PAK concentrate agent intothe system with a small amount of water and air.This mixture creates a large volume of expandedwet 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 improves safety and canincrease productivity by 30% by reducing yourdump/fill cycle. It will also reduce chemical usageand storage space. One FaST−PAK ofconcentrated agent can scrub up to 90,000 m2 (1million square feet).

NOTE: Do not use the FaST system withconventional cleaning detergents in the solutiontank. Drain, rinse and refill the solution tank withclear cool water before operating the FaSTsystem. Conventional cleaning detergents maycause failure to the FaST system.

OPERATION

8 T7 331040 (9−2013)

ec−H2O SCRUBBING (ec−H2O Model)

The ec−H2O (electrically converted water) systemoperates by producing electrically converted 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 theec−H2O system. Conventional cleaningdetergents/ restorers may cause failure to theec−H2O solution system.

NOTE: Storage or transporting machinesequipped with ec−H2O in freezing temperaturesrequires special procedures. Follow the freezeprotection procedure located in the STORAGEINFORMATION section.

BRUSH INFORMATION

For best results, use the correct brush type for thecleaning application. The following arerecommended brush applications.

Non-scuff polypropylene brush (Cylindricaland Disk) − This brush uses a softer, generalpurpose polypropylene bristle to lift lightlycompacted soilage without scuffing high-glosscoated floors.
