BATTERY DISCHARGE INDICATOR

The battery discharge indicator shows the chargelevel of the batteries with a segmented display.

When the batteries are fully charged, all thesegments are lit. As the batteries discharge, thesegments shut off.

The batteries should be recharged when all thesegments have shut off. At this point, the batteryicon will begin flashing, and the scrubbingfunctions will automatically shut off to alert theoperator of the battery condition. The squeegeeand vacuum can be operated, with the rearsqueegee switch, for an additional 30 seconds topick up any excess water.

NOTE: Do not charge the batteries more oftenthan is necessary to prolong the life of thebatteries. Do not charge the batteries with a “topoff” charge if there is enough remaining charge inthe batteries for the next machine use. Dischargethe batteries to a 20% level, when the batterydischarge indicator segments shut off, before fullycharging the batteries. Do not allow the batteriesto become completely discharged as this will alsodamage the batteries. See BATTERIES in theMAINTENANCE section.

HOURMETER

The hourmeter records the number of hours themachine has been operating.

The hourmeter will record time when the machineis propelling or when the vacuum fan is operating.This information is useful when maintaining themachine.

HOW THE MACHINE WORKS

The steering wheel controls the direction ofmachine travel. The directional pedal controls thespeed and forward/reverse directions. The brakepedal slows and stops the machine.

The scrub components of the machine are asolution tank, scrub brushes, rear and sidesqueegees, a vacuum system, and a recoverytank.

Water and detergent, from the solution tank, flowto the floor through a solution valve to the scrubbrushes. The brushes scrub the floor. As themachine is moved forward, the squeegees wipethe dirty solution off the floor, which is then pickedup and drawn into the recovery tank.

The optional side brush(es), available only on thecylindrical scrub head machines, sweep lightdebris into the scrubbing path of the machine. Thescrub brushes sweep the debris into the debristrough.

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

The five available scrub head types use disk orcylindrical brushes.

Two different widths of scrub heads are availablefor each type.The MaxPro 1000 disk scrub head contains twodisk scrub brushes, and is available with standardor heavy duty scrubbing motors. The MaxPro1000 disk scrub head is 1020 mm.The MaxPro 1200 disk scrub head contains threedisk scrub brushes, and is 1220 mm.

The MaxPro 1000 cylindrical scrub head is 1020mm.The MaxPro 1200 cylindrical scrub head is1220 mm.

NOTE: The amount and type of soilage play animportant role in determining the type of brushesto be used. For specific recommendations, contactyour Tennant representative.

When finished scrubbing, drain and clean therecovery tank. If using the ES system, drain andclean the solution tank, and clean the ES filter.

FaST SCRUBBING SYSTEM

Unlike conventional scrubbing, the FaST (FoamScrubbing Technology) system operates byinjecting the FaST PAK concentrate agent into thesystem with a small amount of water andcompressed air. This mixture creates a largevolume of expanded wet 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 can increaseproductivity by 30% by reducing your dump/fillcycle. It will also reduce chemical usage andstorage space. One FaST PAK of concentratedagent can scrub up to 1 million sq. ft.

NOTE: Do not enable the FaST system withconventional cleaning detergents in the solutiontank. Drain, rinse and refill the solution tank withclear cool water only before operating the FaSTsystem. Conventional cleaning detergents/restorers may cause failure to the FaST solutionsystem.

NOTE: Storage or transporting machinesequipped with FaST in freezing temperaturesrequires special procedures. Check with aTENNANT representative for advice.

SWEEPING, SCRUBBING AND BRUSHINFORMATION

Pick up oversized debris before cleaning. Pick uppieces of wire, string, twine, etc., which couldbecome wrapped around the sweeping orscrubbing brushes.

Optional side brush sweeping is available only onthe cylindrical scrub head machines.

Plan the sweeping and scrubbing in advance. Tryto arrange long runs with minimum stopping andstarting. Sweep debris from very narrow aislesinto main aisles ahead of time. Do an entire flooror section at one time.

Drive as straight a path as possible. Avoidbumping into posts or scraping the sides of themachine. Overlap the scrub paths by severalcentimeters (a few inches).

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

When scrubbing dead end aisles, start at theclosed 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 solutionflow required for the best results. The machinehas an edge clean feature for all MaxProt 1000scrub heads, for scrubbing against an edge.

If you see poor scrubbing performance, stopscrubbing and refer to MACHINETROUBLESHOOTING.

For best results, use the correct brush type foryour cleaning application. The following arerecommended brush applications.

HYDRAULICS (OPTION)

HYDRAULIC FLUID RESERVOIR

The hydraulic reservoir holds the hydraulic fluid forthe power steering option. It is located underneaththe front cover of the machine. A filler cap ismounted on top of the reservoir.

Check the hydraulic fluid level at operatingtemperature after every 100 hours of operation.The reservoir should be filled to 2” +/-- .5” belowthe top of the reservoir. The top of the springassembly that holds down the filter inside thereservoir can be used as a gauge.

Lubricate the filler cap gasket with a film ofhydraulic fluid before putting the cap back on thereservoir.

Drain and refill the hydraulic fluid reservoir withnew hydraulic fluid after every 500 hours ofoperation.

ATTENTION! Do not overfill thehydraulic fluid reservoir or operate themachine with a low level of hydraulicfluid in the reservoir. Damage to themachine hydraulic system may result.

The reservoir has a built--in filter outlet that filtershydraulic fluid before it enters the system.Replace the filter every 500 hours of operation.

HYDRAULIC FLUID

The quality and condition of the hydraulic fluid play

a very important role in how well the machine

operates. Tennant’s hydraulic fluid is specially

selected to meet the needs of Tennant machines.

Tennant’s hydraulic fluids provide a longer life forthe hydraulic components.

If another hydraulic fluid is used, make sure the

specifications match Tennant hydraulic fluidspecifications. Using substitute fluids can cause

premature failure of hydraulic components.

ATTENTION! Hydraulic componentsdepend on system hydraulic fluid forinternal lubrication. Malfunctions,accelerated wear, and damage will resultif dirt or other contaminants enter thehydraulic system.

HYDRAULIC HOSES

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

Fluid escaping at high pressure from a very smallhole can be almost invisible, and can causeserious injuries.

See a doctor at once if injury results fromescaping hydraulic fluid. Serious infection orreaction can develop if proper medical treatment isnot given immediately.

FOR SAFETY: When servicing machine,use cardboard to locate leakinghydraulic fluid under pressure.

If you discover a fluid leak, contact your mechanicor supervisor.

BATTERIES

The batteries are unique in that they hold theirpower for long periods of time. The lifetime of thebatteries is limited by the number of charges thebatteries receive. To get the most life from thebatteries, charge them when all the batterydischarge indicator segments shut off (20%charge left). Use an automatic charger with theproper rating for the batteries.

Periodically clean the top surface of the batteriesand terminals with a strong solution of bakingsoda and water. Brush the solution sparingly overthe battery tops, terminals, and cable clamps. Donot allow any baking soda solution to enter thebatteries. Use a wire brush to clean the terminalposts and the cable connectors. After cleaning,apply a coating of clear battery post protectant tothe terminals and the cable connectors. Check thebatteries for loose connections. Keep the tops ofthe batteries clean and dry.

Keep all metallic objects off the top of thebatteries, which may cause a short circuit.Replace any worn or damaged wires.

Check the electrolyte level in each battery cellbefore and after charging, and after every 50hours of operation. Do not charge the batteriesunless the fluid is slightly above the battery plates.If needed, add just enough distilled water to coverthe plates. Never add acid to the batteries. Do notoverfill. Always keep the battery caps on, exceptwhen adding water or taking hydrometer readings.

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