OPERATION

HOW THE MACHINE WORKS

This machine can effectively scrub or sweep dirty floors. The 1−STEP Scrub button and 1−STEP Sweep button make it possible to immediately begin scrubbing or sweeping.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​‌​‍​​​‌​⁠​​‍​​‌⁠‍⁠⁠​⁠‍‍‌‌⁠‌⁠‍⁠​⁠​⁠⁠

The 1−STEP Sweep button operates all the dry sweeping functions (without scrubbing). The 1−STEP Scrub button operates all the scrubbing functions. (The machine also sweeps while scrubbing).

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

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 double scrubbing and heavy duty scrubbing applications.

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 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 while double scrubbing.

BRUSH INFORMATION

For best results, use the correct brush type for the cleaning application. Listed below are the brushes and the applications for which each is best suited.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​‌​⁠​​​‌​⁠​​‌‌‌⁠‍‍‌‍‌‌‌​⁠‍⁠‌‌‍‍‌​‌⁠⁠

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

Polyester brush − Softer general purpose polyester bristles lift light debris while sweeping and gently clean while scrubbing. Perfect for sensitive floor surfaces. Polyester does not absorb water so it is preferred over Nylon in wet applications.

Super AB brush − Nylon fiber impregnated with abrasive grit to remove stains and compacted dirt. Aggressive action on any surface. Performs well on buildup, grease, or tire marks.

WHILE OPERATING THE MACHINE

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

Drive as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine. Overlap the scrub/sweep 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 the machine is equipped with the FaST or ec−H2O system, use the FaST or ec−H2O system for the best scrubbing results.

Keep the machine moving to prevent damaging floor finishes.

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.

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 10%. The maximum rated incline during transport of the machine is14%.

MAINTENANCE

HYDRAULICS

Check the hydraulic fluid level at operating temperature daily. The hydraulic fluid level should be between the two lines on the hydraulic gauge. The hopper must be down when checking hydraulic fluid level.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​⁠‌‍​​​‌​⁠​​‌‍‌⁠⁠​‍‍‍‍‌‍‍‌⁠​‍‌​⁠‍‌‍​

Drain and refill the hydraulic fluid reservoir with new TennantTrue premium hydraulic fluid after every 2400 hours of operation. Machines have a blue colored drop (left photo) on the hydraulic fluid label if originally equipped with TennantTrue premium hydraulic fluid.

Replace the filler cap after every 800 hours of operation. Apply a light film of hydraulic fluid onto the filler cap gasket before installing the cap onto the reservoir.

Replace the hydraulic fluid filter after every 1200 hours of operation or if the hydraulic reservoir gauge is in the yellow/red zone when the reservoir hydraulic fluid is approximately 32° C (90° F).

Replace the hydraulic strainer outlet after every 2400 hours of operation.

HYDRAULIC FLUID

There are three fluids available for different temperature ranges:‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​⁠‌⁠​​​‌​⁠​​‍⁠​‌​​⁠⁠⁠‍⁠‌​‍​‍⁠‍‍‍⁠‍​‌

If using a locally-available hydraulic fluid, be sure the specifications match Tennant hydraulic fluid specifications. Substitute fluids can cause premature failure of hydraulic components.

HYDRAULIC HOSES

Check the hydraulic hoses after every 800 hours of operation for wear or damage.

High pressure fluid escaping from a very small hole can almost be invisible, and can cause serious injuries.

Consult a physician immediately if injury results from escaping hydraulic fluid. Serious infection or reaction can occur if proper medical treatment is not given immediately.

Contact a mechanic or supervisor if a leak is discovered.

MAINTENANCE

ENGINE

COOLING SYSTEM

Check the coolant level in the reservoir daily. The coolant level must be between the indicator marks when the engine is cold. Refer to the coolant manufacture for water/coolant mixing instructions.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​⁠‍​​​​‌​⁠​​‍‌⁠‌⁠‌⁠‍​​​‍​⁠⁠​‌​‌​‌‌⁠​

Flush the radiator and the cooling system after every 800 hours of operation.

Check the radiator hoses and clamps after every 200 hours of operation. Tighten loose clamps. Replace damaged hoses and clamps.

Check the radiator core exterior and hydraulic cooler fins for debris after every 100 hours of operation. Blow or rinse all dust through the grille and radiator fins, in the opposite direction of normal air flow. Be careful to not bend the cooling fins when cleaning. Clean thoroughly to prevent the fins from becoming encrusted with dust. To avoid cracking the radiator, allow the radiator and cooler fins to cool before cleaning.

MAINTENANCE

AIR FILTER

Replace the air filter after every 400 hours of operation.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​⁠‍‌​​​‌​⁠​​‍​‌‍‍‌​‌‌‌‍​‌‌‌⁠‍‌‌‌‌⁠​‌

FUEL FILTER

The fuel filter removed imputities from the fuel. Replace the fuel filter after every 400 hours of operation.

FUEL LINES

Check the fuel lines every 50 hours of operation. If the clamp band is loose, apply oil to the screw of the band and securely tighten the band.

The rubber fuel lines can become worn−out whether the engine has been used much or not. Replace the fuel lines and clamp bands every two years.

If the fuel lines and clamp bands are found worn or damaged before two years’ time; replace or repair them at once. Bleed the fuel system after replacement of any fuel lines, see PRIMING THE FUEL SYSTEM. When the fuel lines are not installed, plug both ends with clean cloth or paper to prevent dirt from entering the lines. Dirt in the lines can cause fuel injection pump malfunction.

MAINTENANCE

PRIMING THE FUEL SYSTEM

Typical diesel fuel systems require priming to remove pockets of air from the fuel lines and fuel components. This is usually required after running out of fuel, changing fuel filter elements or repairing a fuel system component. Air in the fuel prevents smooth engine operation.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​⁠‍‍​​​‌​⁠​​‌‍‌‌​‍⁠⁠⁠​⁠⁠‍​‍‍‍‍​⁠‍‌⁠‍

This fuel system however is self-priming. The return line comes from the top of the injector that allows the air to escape through the return line.

ENGINE BELT

Check the belt tension after every 50 hours of operation. Adjust tension as necessary. Proper belt tension is 13 mm (0.50 in) from a force of 4 to 5 kg (8 to 10 lb) applied at the mid-point of the longest span.

BATTERY

Clean and tighten the battery connections after the first 50 hours of operation and after every 800 hours after that. Do not remove the vent plugs from the battery or add water to the battery.

FUSES AND RELAYS

RELAY PANEL FUSES AND RELAYS

Fuses are one-time protection devices designed to protect the wire harness by stopping the flow of current in the event of a circuit overload. Relays switch the electrical power going to the machine electrical systems on/off. Remove the relay panel cover to access fuses and relays.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​​⁠‍⁠​​​‌​⁠​​‌⁠‌‍⁠‌⁠‌‍‍​​‌⁠‍⁠‌‍​‌‍⁠⁠‌

REPLACING OR ADJUSTING THE SIDE BRUSH SQUEEGEE BLADE (S/N 001279− ) (OPTION)

Check the side brush squeegee blade for damage and wear daily. Replace the blade if the leading edge is torn or worn half-way through the thickness of the blade.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌​‍‍​​​‌​⁠​​​​⁠​‍​‌‍‌​⁠​‍‍‌‍‌‌⁠​⁠​​​

1. Lower the scrub head.
2. Pull the pins and remove the squeegee bumper.

3. Open the retaining band tension latch.

4. Remove the squeegees, spacer, and retainer from the squeegee bumper.

5. Reinstall the squeegees, spacer, and retainer to the squeegee bumper by aligning the appropriate holes to the pins on the bumper.

6. Reinstall the retaining band tension latch.
7. Reinstall the squeegee bumper and reinsert the pins.

LEVELING THE REAR SQUEEGEE

Leveling the squeegee assures the entire length of the squeegee blade is in even contact with the surface being scrubbed. Perform this adjustment on an even and level floor.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌​‍⁠​​​‌​⁠​​⁠⁠​‌⁠⁠⁠​⁠‍⁠‌⁠⁠‌‌‍⁠⁠​⁠‌‍‌

1. Lower the squeegee and drive the machine forward a few meters (feet).

2. Look at the deflection of the squeegee over the full length of the squeegee blade.
3. If the deflection is not the same over the full length of the blade, turn the squeegee levelling nut to make adjustments.

4. Turn the squeegee leveling nut counter-clockwise to decrease the deflection at the ends of the squeegee blade.
   
   Turn the squeegee leveling nut clockwise to increase the deflection at the ends of the squeegee blade.
5. Drive the machine forward with the squeegee down to recheck the squeegee blade deflection if adjustments were made.
6. Readjust the squeegee blade deflection if necessary.

ADJUSTING THE REAR SQUEEGEE BLADE DEFLECTION

Deflection is the amount of curl the overall squeegee blade has when the machine moves forward. The best deflection is when the squeegee wipes the floor dry with a minimal amount of deflection.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌​⁠​​​​‌​⁠​​​⁠‍‌⁠⁠‌⁠‍⁠⁠⁠‌‌‍​​‌⁠⁠‌​​​

1. Lower the squeegee and drive the machine forward a few meters (feet).

2. Look at the amount of deflection or “curl” of the squeegee blade. The correct amount of deflection is 12 mm (0.50 in) for scrubbing smooth floors and 15 mm (0.62 in) for rough floors.

3. To adjust the overall squeegee blade deflection, turn the adjustment knobs counterclockwise to increase deflection or clockwise to decrease deflection.

4. Drive the machine forward again to recheck the squeegee blade deflection after adjustments are made.
5. Readjust the squeegee blade deflection if necessary.

SKIRTS AND SEALS

SCRUB HEAD SKIRT

Check the skirt for damage and wear after every 100 hours of operation.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌​⁠‌​​​‌​⁠​​‍‍​​⁠​‍​‍⁠‌‍​‌⁠‍⁠‍⁠‍​​‌​

The skirts should be between 0 to 6 mm (0 to 0.25 in) from the floor when the scrub head is down.

RECOVERY TANK SEAL

Check the recovery tank cover seal for damage and wear daily.

SOLUTION TANK SEALS

Check each solution tank cover seal for damage and wear daily.

BRAKES AND TIRES

BRAKES

The mechanical brakes are located on the rear wheels. The brakes are operated by the foot brake pedal and connecting cables.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌​⁠‍​​​‌​⁠​​‍‍⁠‌‍‍⁠⁠‌⁠‍‍‍‍‍‌‍⁠‌‌⁠⁠⁠‍

Check the brake adjustment after every 200 hours of operation.

To check the brake adjustment, measure the distance from the stationary brake pedal to the point where there is resistance in the pedal movement. The distance must be between 6 mm (0.25 in) and 19 mm (0.75 in). Adjust the brakes if required.

TIRES

Check tires for damage and wear after every 100 hours of operation.

FRONT WHEEL

Torque the front wheel nuts twice in the pattern shown to 122 to 149 Nm (90 to 110 ft lb) after the first 50 hours of operation, and after every 800 hours there after.

PROPELLING MOTOR

Torque the shaft nut to 508 Nm (375 ft lb) lubricated, 644 Nm (475 ft lb) dry, after every 800 hours of operation.

PUSHING, TOWING, AND TRANSPORTING THE MACHINE

PUSHING OR TOWING THE MACHINE

If the machine becomes disabled, it can be pushed from the front or rear, but only towed from the front.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌​⁠⁠​​​‌​⁠​​⁠⁠⁠⁠‌⁠‍​⁠‍‍⁠⁠‌⁠​⁠⁠‌‍​⁠⁠‍

The propelling pump has a bypass valve to prevent damage to the hydraulic system when the machine is being pushed or towed. This valve allows a disabled machine to be moved for a very short distance and at a speed to not exceed 1.6 kp/h (1 mph). The machine is NOT intended to be pushed or towed a long distance or at a high speed.

Turn the bypass valve located on the bottom of the propelling pump 90° (either direction) from the normal position before pushing or towing the machine. Return the bypass valve back to the normal position when through pushing or towing the machine. Do Not use the bypass valve during normal machine operation.

TRANSPORTING THE MACHINE

1. Raise the squeegee, scrub head, and brushes. If necessary, raise the hopper for additional ramp clearance.

2. Position the rear of the machine at the loading edge of the truck or trailer.
3. If the loading surface is not horizontal or is higher than 380 mm (15 in) from the ground, use a winch to load machine.
   
   If the loading surface is horizontal and 380 mm (15 in) or less from the ground, the machine may be driven onto the truck or trailer.

4. To winch the machine onto the truck or trailer, attach the winching chains to the holes in the rear jacking brackets behind the rear tires.

5. Position the machine as close to the front of the trailer or truck as possible.
6. Set the parking brake and place a block behind each wheel to prevent the machine from rolling.
7. Lower the scrub head.

8. Connect the tie-down straps to the holes in the right and left lower corners in front of the machine and the holes in the rear jacking brackets behind the rear tires.

9. Route the tie-downs to the opposite ends of the machine and hook them to the brackets on the floor of the trailer or truck. Tighten the tie-down straps.

10. If the loading surface is not horizontal or is higher than 380 mm (15 in) from the ground, use a winch to unload machine.
    
    If the loading surface is horizontal AND is 380 mm (15 in) or less from the ground, the machine may be driven off the truck or trailer.

MACHINE JACKING

Empty the hopper, recovery tank, and solution tank before jacking up the machine. Jack up the machine at the designated locations. Use a hoist or jack capable of supporting the weight of the machine. Use jackstands to support the machine. Always stop the machine on a flat, level surface and block the tires before jacking up the machine.‌‌​⁠‌⁠​​‌‌⁠​⁠​​‍‍‌​‌​​​​‌‌​‌​​​‌​⁠​​​‍​⁠​‍⁠​⁠⁠‌‍‌‌⁠‌​‍​⁠‌​‌‍

Rear jacking locations are located directly behind the rear tires on each side of the machine.

Front jacking locations are located on the frame directly in front of the front tire.
