OPERATION

HOW THE MACHINE WORKS

The steering wheel controls the direction of machine travel. The directional pedal controls the speed and forward/reverse directions. The brake pedal slows and stops the machine.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​​‍‍‌​​​‌​⁠​​‍⁠‍⁠⁠‍⁠⁠⁠​⁠‌‌‍‌‍‍‌‍‍⁠⁠‌‍

The machine consists of separate sweeping and scrubbing components.

The sweeping components of the machine are a debris hopper, hopper dust filter, sweeping brushes and a cylindrical conveyor.

The side brush sweeps debris into the path of the main sweeping brush. The main brush sweeps debris from the floor and up the the cylindrical conveyor. The cylindrical conveyor lifts the debris up into the hopper. The vacuum system pulls dust and air through the hopper and hopper dust filter.

The scrub components of the machine are a solution tank, scrub brushes, rear and side squeegees, a vacuum system, and a recovery tank.

Water and detergent, from the solution tank, flow to the floor through a solution valve to the scrub brushes. The brushes scrub the floor. As the machine is moved forward the squeegees wipe the dirty solution off the floor, which is then picked up and drawn into the recovery tank.

When using the ES mode, the solution in the recovery tank is filtered and returned to the solution tank to be reused.

The five available scrub head types use disk or cylindrical brushes.

Two different widths of scrub heads are available for each type.
The MaxPro 1000 disk scrub head contains two disk scrub brushes, and is available with standard or heavy duty scrubbing motors. The MaxPro 1000 disk scrub head is 1016 mm (40 in).
The MaxPro 1200 disk scrub head contains three disk scrub brushes, and is 1220 mm (48 in).

The MaxPro 1000 cylindrical scrub head is 1016 mm (40 in).
The MaxPro 1200 cylindrical scrub head is 1220 mm (48 in).

OPERATION

When finished sweeping and scrubbing, clean the hopper dust filter, empty the hopper, and drain and clean the recovery tank. If using the ES system, drain and clean the solution tank, and clean the ES filter.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​​‍‍‍​​​‌​⁠​​​⁠⁠⁠‍​‌⁠‌‍‌⁠‍‌‌​⁠⁠‍​⁠⁠⁠⁠

FaST SCRUBBING SYSTEM

Unlike conventional scrubbing, the FaST (Foam Scrubbing Technology) system operates by injecting the FaST PAK concentrate agent into the system with a small amount of water and compressed air. This mixture creates a large volume of expanded wet foam.

The expanded foam mixture is then dispersed onto the floor while the machine is scrubbing. When the squeegee picks up the mixture, the patented foaming agent has collapsed and is recovered into the recovery tank.

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

Using the FaST system can increase productivity by 30% by reducing your dump/fill cycle. It will also reduce chemical usage and storage space. One FaST PAK of concentrated agent can scrub up to 1 million sq. ft.

ec−H2O SYSTEM (OPTION)

The ec−H2O (electrically converted water) system operates by producing electrically converted water for cleaning.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​​‍‍⁠​​​‌​⁠​​⁠​⁠​​‌‌‍​‍‌​‌‍‍‌‍⁠⁠​‍‍‌⁠

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 applications.

PRE-OPERATION CHECKLIST

SWEEPING, SCRUBBING AND BRUSH INFORMATION

Pick up oversized debris before cleaning. Pick up pieces of wire, string, twine, etc., which could become wrapped around the sweeping or scrubbing brushes.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​​⁠​⁠​​​‌​⁠​​​‌​⁠‌‌‍​​⁠‍⁠​‍⁠⁠‍‍‍​‍‌⁠‍

Plan the sweeping and scrubbing in advance. Try to arrange long runs with minimum stopping and starting. Sweep debris from very narrow aisles into main aisles ahead of time. Do an entire floor or section at one time.

Drive as 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.

When scrubbing dead end aisles, start at the closed end of the aisle and scrub your way out.

Adjust the machine speed, scrub brush pressure, and solution flow as required when scrubbing. Use minimum scrub brush pressure and solution flow required for the best results. The machine has an edge clean feature for all MaxPro 1000 scrub heads, for scrubbing against an edge.

If you see poor scrubbing performance, stop scrubbing and refer to MACHINE TROUBLESHOOTING.

For best results, use the correct brush type for your cleaning application. The following are recommended brush applications.

Polypropylene side sweeping brush − A general purpose brush for sweeping of light to medium debris in both indoor and outdoor applications. This brush is recommended in places where bristles may get wet.

The steering gear chain is located by the foot pedals. Lubricate the chain with SAE 90 weight gear lubricant after the first 50, and then after every 500 hours of operation.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​‌‌‍‍​​​‌​⁠​​‌​‍‍‍‍‍​‍​⁠​‌⁠⁠‌‌‍‍‌⁠​​​

HOPPER LIFT DRIVE CHAIN

The hopper lift drive chain is located on the left hand side of the machine, close to the hopper. Lubricate the chain with SAE 90 weight gear lubricant after the first 50, and then after every 500 hours of operation.

HOPPER TILT DRIVE CHAIN

The hopper tilt drive chain is located on the left hand side of the machine, along side the hopper lift arm. Lubricate the chain with SAE 90 weight gear lubricant after the first 50, and then after every 500 hours of operation.

HYDRAULICS

HYDRAULIC FLUID RESERVOIR

The hydraulic reservoir holds the hydraulic fluid for the hydrualic lift cylinder and the power steering unit. It is located underneath the front cover of the machine. A filler cap is mounted on top of the reservoir.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​‌‌‍⁠​​​‌​⁠​​⁠⁠‌⁠‌​​​​⁠‍⁠⁠⁠⁠‍‍​⁠‍‌‍​⁠

Check the hydraulic fluid level at operating temperature after every 100 hours of operation. For machines serial number 07329 and below, fill the resrvoir to about50mm (2in) below the top of the reservoir. For machines serial number 07330 and above, fill the resrvoir to about 23mm (1 in) below the top of the reservoir.

Lubricate the filler cap gasket with a film of hydraulic fluid before putting the cap back on the reservoir.

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.

The reservoir has a built−in filter outlet that filters hydraulic fluid before it enters the system. Replace the filter every 1200 hours of operation.

HYDRAULIC FLUID

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

HYDRAULIC HOSES

Check the hydraulic hoses after every 500 hours of operation for wear or damage.

Fluid escaping at high pressure from a very small hole can be almost invisible, and can cause serious injuries.

See a doctor at once if injury results from escaping hydraulic fluid. Serious infection or reaction can develop if proper medical treatment is not given immediately.

If you discover a fluid leak, contact your mechanic or supervisor.

BATTERIES

The lifetime of the batteries depends on their proper maintenance. To get the most life from the batteries;‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​‌‌⁠‌​​​‌​⁠​​​‌​⁠⁠‍‌⁠​‍‌‌​‌‌⁠‌​‌​‍⁠​‍

• Do not charge the batteries more than once a day and only after running the machine for a minimum of 15 minutes.
• Do not leave the batteries partially discharged for long period of time.
• Only charge the batteries in a well-ventilated area to prevent gas build up. Charge batteries in areas with ambient temperatures 27°C (80°F) or less.
• Allow the charger to complete charging the batteries before re-using the machine.
• Maintain the proper electrolyte levels of flooded (wet) batteries by checking levels weekly.

CHECKING THE ELECTROLYTE LEVEL

The flooded (wet) lead−acid batteries require routine maintenance as described below. Check the battery electrolyte level weekly.

The level should be slightly above the battery plates as shown before charging. Add distilled water if low. DO NOT OVERFILL. The electrolyte will expand and may overflow when charging. After charging, distilled water can be added up to about 3 mm (0.12 in) below the sight tubes.

MAINTENANCE−FREE BATTERIES

Maintenance−free batteries do not require watering. Cleaning and other routine maintenance is still required.‌‌​⁠​​⁠⁠​⁠‍‍‍‌​​‌‍‍⁠​​​​‌‌⁠‍​​​‌​⁠​​‍​‍​​‍⁠‍‌⁠⁠‍‍⁠‍‌‌‍​‍⁠⁠⁠⁠

CHECKING CONNECTIONS / CLEANING

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. Replace any worn or damaged wires. Do not remove battery caps when cleaning batteries.
