OPERATION

HOW THE MACHINE WORKS

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 ES (Extended Scrub) mode, the dirty solution in the recovery tank is filtered through the ES system and returned to the solution tank for reuse. Detergent is then injected into the returned solution to revitalize the cleaning capability of the solution.

When in the optional FaST (Foam scrubbing) mode, the FaST scrubbing system mixes the

FaST--PAK concentrate with a small amount of water, creating a large volume of expanded wet foam. The FaST system can be used with all scrubbing applications.

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.

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)-- Quickly and easily cuts through old finish to prepare the floor for recoating.

Scrubbing pad (Blue) -- Removes dirt, spills, and scuffs. Leaves a clean surface ready for recoating.

Buffing pad (Red) -- Quickly cleans and removes scuff marks while polishing the floor to a high gloss.

Polishing pad (White) -- Maintains a high gloss.

Use for buffing very soft finishes and lower traffic areas, and polishing soft waxes on wood floors.

Go To..

High productivity pad (Black) -- Aggressively strips floor finishes/sealers. Use 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) --

Aggressively strips floors without use of chemicals.

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 Tennant pads except the black high productivity pad.

OPERATION

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.

The maximum rated incline for scrubbing with the machine is 4_ or 7%. The maximum rated incline during transport of the machine is 8_ or 14%.

OPERATION

SETTING SCRUB MODES

The Scrub mode button enables the scrubbing functions to come on when the 1--STEP button is activated. The light and cleaning system logo next to the button will come on. The machine will default to the last setting used when it is powered on or off.

SETTING SOLUTION FLOW

With the 1--STEP button activated, press either

Solution increase button (+) or Solution decrease

button (--) to set the solution flow level. Travel speed and floor conditions will affect scrubbing performance. The machine will default to the last setting used when the machine is powered on or off. The solution flow indicator lights display the current solution flow setting.

NOTE: When using the FaST or ec--H2O system

(option), the solution flow increase and solution flow decrease buttons are nonfunctional. The

FaST and ec--H2O system flow rates are pre--set.

All three solution flow indicator lights will be lit if the machine is in the ec--H2O or FaST mode.

NOTE: When the ES system is turned on there is a slight delay before the ES pump begins operating.

SETTING BRUSH PRESSURE

Under normal cleaning conditions, the brush pressure should be set to the lowest setting (the bottom light). Under heavy grime conditions, the brush pressure can be set to a higher setting (the top two lights). Travel speed and floor conditions will affect cleaning performance.

With the 1--STEP button activated, press the

Brush pressure button to set the brush pressure.

Use the Brush pressure button to both raise or lower the brush pressure settings. If brushes are worn, it may be necessary to increase the brush pressure. The machine will default to the last setting used when it is powered on or off.

CONVENTIONAL SOLUTION FLOW

Under normal soilage conditions the solution flow level should be set to the lowest setting (the left light). Under heavy grime conditions, the solution flow level should be set to the higher settings

(middle or right lights).

ES (EXTENDED SCRUB) SOLUTION FLOW

For ES machines, the detergent flow is turned off when the solution flow is in the lowest

setting (one light). The middle setting (two lights) and highest setting (three lights) allow solution AND detergent flow. The lowest setting

(one light) allows solution flow WITHOUT adding detergent. Detergent does not have to be continuously added with the solution flow to attain effective scrubbing results. Under normal soilage conditions, the solution flow level should be alternated between the middle and lowest setting.

The batteries are designed to hold their power for long periods of time between charges. The lifetime of the batteries is limited by the number of charges the batteries receive. To get the most life from the batteries, charge them when the last battery discharge indicator segment flashes (20% charge left). Use an automatic charger with the proper rating for the batteries.

Check the electrolyte level in each battery cell before and after charging, and after every 50 hours of operation. Do not charge the batteries unless the fluid is slightly above the battery plates.

If needed, add just enough distilled water to cover the plates. Never add acid to the batteries. Do not overfill. Always keep the battery caps on, except when adding water or taking hydrometer readings.

After every 200 hours of use check for loose battery connections and clean the surface of the batteries, including terminals and cable clamps, with 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 the batteries. Use a wire brush to clean the terminal posts and the cable connectors. Wipe off all cleaning solution residue. After cleaning, apply a coating of battery terminal protector to the terminals and the cable connectors. Keep the tops of the batteries clean and dry.

Objects made of metal can potentially short circuit the batteries. Keep all metallic objects off the batteries. Replace any worn or damaged wires.

MAINTENANCE

Measuring the specific gravity, using a hydrometer, is a way to determine the charge level and condition of the batteries. If one or more of the battery cells test lower than the other battery cells (0.050 or more), the cell is damaged, shorted, or is about to fail.

04380

NOTE: Do not take readings immediately after adding distilled water. If the water and acid are not thoroughly mixed, the readings may not be accurate. Check the hydrometer readings against the following chart to determine the remaining battery charge level:

CIRCUIT BREAKERS

Circuit breakers are resettable electrical circuit protection devices designed to stop the flow of current in the event of a circuit overload. Once a circuit breaker is tripped, reset it manually by pressing the reset button after the breaker has cooled down.

Circuit breakers 1 through 10 are located in the front of the battery compartment.

Circuit breakers 11 through 19 are located on the electrical panel.

Circuit breaker 20 is located inside the optional light assembly mounted on top of the recovery tank.

If the overload that caused the circuit breaker to trip is still present, the circuit breaker will continue to stop current flow until the problem is corrected.
