HOW THE MACHINE WORKS

T12 With Cylindrical Brushes

T12 With Disk Brushes

The 1--STEP button makes it possible to

immediately begin scrubbing by operating all the scrubbing functions.

When in the conventional Scrub mode, a water and detergent mixture is used to scrub the floor.

When in the optional ec--H2O (electrically

converted water) mode, normal water passes through a module where it is oxygenated and charged with an electric current. The electrically converted water changes into a blended acidic and alkaline solution forming a neutral pH cleaner. The converted water attacks the dirt, breaks it into smaller particles, and pulls it off the floor surface allowing the machine to easily scrub away the suspended soil. The converted water then returns

to normal water in the recovery tank. The ec--H2O

system can be used with all double scrubbing and heavy duty scrubbing applications.

OPERATION

T12 9009918 (3--2013)

BRUSH AND PAD INFORMATION

For best results, use the appropriate brush or pad for the cleaning application. Listed below are brushes and pads and the applications for which each is best suited.

NOTE: The amount and type of soilage play an important role in determining the type of brush or pad to use. Contact a Tennant representative for specific recommendations.

Nylon brush (Disk)* -- Softer nylon bristles are

recommended for scrubbing coated floors. Cleans without scuffing.

Polyester brush (Cylindrical) -- Softer general

purpose polyester bristles gently clean while scrubbing. Perfect for sensitive floor surfaces. Polyester does not absorb water so it is preferred over Nylon in wet applications.

PolyPro brush (Cylindrical) -- Heavy duty

polypropylene bristles provide a more aggressive cleaning performance and can more easily lift compacted dirt, debris, and sand while offering excellent scrubbing performance.

Polypropylene brush (Cylindrical and Disk)* --

General purpose polypropylene bristles lift lightly compacted dirt without scuffing high-gloss coated floors.

Super AB brush (Cylindrical and Disk)* -- Nylon

fiber with an abrasive grit to remove stains and compacted dirt. Aggressive action on any surface. Performs well on buildup, grease, or tire marks.

* This brush is also available for the side brush. Stripping pad (Brown)-- For stripping of floor

finish to prepare the floor for recoating.

Scrubbing pad (Blue) -- For medium to

heavy-- duty scrubbing. Removes dirt, spills, and scuffs.

Buffing pad (Red) -- For light duty scrubbing

without removing floor finish.

Polishing pad (White) -- For maintaining highly

polished or burnished floors.

High productivity stripping pad (Black) -- F o r

aggressive stripping of heavy finishes or sealers,

or for very heavy duty scrubbing. This pad can

only be used with the grip pad driver, not the tufted pad driver.

Surface preparation pad (Maroon) -- F o r v e r y

aggressive chemical free removal of floor finish to prepare the floor for re--coating

Grip pad driver -- The grip--face backing allows

pads to be fully used and holds pads in place without penetrating the pad. The spring--activated centering device works with all Tennant pads and allows for fast, easy pad replacement.

Tufted pad driver -- Standard pad driver has

short bristles, or “tufts,” on the back to hold the pad in place. This driver works with all T ennant pads except the black high productivity pad.

OPERATION

T12 9009918 (3--2013)

WHILE OPERATING THE MACHINE

Pick up oversized debris before scrubbing. Pick up wire, string, twine, large pieces of wood, or any other debris that could become wrapped around or tangled in the brushes.

Drive in a straight a path as possible. Avoid bumping into posts or scraping the sides of the machine. Overlap the scrub paths by several centimeters (a few inches).

Avoid turning the steering wheel too sharply when the machine is in motion. The machine is very responsive to the movement of the steering wheel. Avoid sudden turns, except in emergencies.

Adjust the machine speed, brush pressure, and solution flow as required when scrubbing. Use the lowest brush pressure and solution flow settings for best performance.

If poor cleaning performance is observed, stop

cleaning and refer to MACHINE TROUBLESHOOTING in this manual.

Perform the Daily Maintenance Procedures after each use (see MACHINE MAINTENANCE in this manual).

Drive the machine slowly on inclines. Use the brake pedal to control machine speed on descending inclines. Scrub with the machine up inclines rather than down inclines.

FOR SAFETY: When using machine, go slowly on inclines and slippery surfaces.

Do not operate machine in areas where the ambient temperature is above 43_ C(110_ F). Do not operate scrubbing functions in areas where the ambient temperature is below freezing 0_ C (32_ F).

The maximum rated incline for scrubbing with the machine is 7%. The maximum rated incline during transport of the machine is 14.1%.
