SWEEPING AND BRUSH INFORMATION

Pick up oversized debris before sweeping. Flattenor remove bulky cartons from aisles beforesweeping. Pick up pieces of wire, twine, string,etc., which could become entangled in brush orbrush plugs.

Plan the sweeping in advance. Try to arrange longruns with minimum stopping and starting. Sweepdebris from very narrow aisles into main aislesahead of time. Do an entire floor or section at onetime. Sweep as straight a path as possible. Avoidbumping into posts or scraping the sides of thesweeper. Overlap the brush paths.

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

Use the Power Throw when picking up light litter.This will improve both litter pickup and hopperloading. Do not use the Power Throw speed industy environments. The machine can dust andclog the hopper dust filter. Operate the main brushin the Normal position when picking up generaldebris.

For best results, use the correct brush type foryour sweeping application. The following arerecommendations for main and side brushapplications.

Polypropylene 8-double Row Main Brush --Gives superior pickup of sand, gravel, and paperlitter. Retains its stiffness when wet, and can beused indoor or out. Not recommended forhigh-temperature debris.

Polypropylene and Wire 8-double Row MainBrush -- The wire bristles loosen slightly packedsoilage and heavier debris. The polypropylenebristles sweep up the debris with excellent hopperloading.

This brush is recommended for foundrysweeping where heat may melt synthetic bristles.This brush has good hopper loading ability, but isnot recommended for dusty applications.

Nylon 24-row Main Brush -- Recommended forsevere dust conditions on rough surfaces. Thisbrush has excellent pickup and long life.

Nylon Patrol Main Brush -- Designed forsweeping large indoor or outdoor areas at higherspeed. The patrol pattern gives excellent loadingof light bulky debris (leaves and paper), while thenylon bristle gives long life.

Heavy Gauge Polypropylene 8-double RowMain Brush -- Designed for sweeping outdoorareas. The stiffer bristles allow excellent loadingof heavier bulky debris (leaves and paper litter).

Polypropylene Side Brush -- A good generalpurpose brush for sweeping of light to mediumdebris in both indoor and outdoor applications.This brush is recommended when bristles mayget wet.

Nylon Side Brush -- A longer life, generalpurpose brush that is recommended for roughsurfaces.

Flat Wire Side Brush -- Recommended foroutside and curb-side sweeping where soilage isheavy or compacted. The stiff wire bristles dig outsoilage. This brush is also recommended forfoundry sweeping where heat may melt syntheticbristles.

REGENERATIVE FILTER SYSTEM (RFS)

The Regenerative Filter System (RFS) is anoption that alternately turns on the filter shakermotors when the filters need cleaning because ofa build--up of dust or debris.

Normally the RFS does not require the operator tostop the machine to shake the filters duringsweeping operation (except in extreme andsevere dust environments). However, it isrecommended that the filters are shaken at theoperator’s initiative each time the hopper isdumped. This can be accomplished during transitto a dump sight. AVOID shaking the filters whilehopper is in a rolled out position. To initiate ashaking cycle, press the filter button on theinstrument panel. See FILTER SHAKERSWITCH.

In very severe dust environments, the pluggedfilter indicator on the instrument panel may remainlit. When this occurs, it is recommended that theoperator stop the machine and initiate one or twoshake cycles to clear a possible plugged filtercondition. After shaking, roll the hopper out toevacuate the dust tray. Resume sweepingoperation.

If the hopper is over full, the light may come on.Check the hopper load and dump if necessary.

If the filter light remains on after all the aboveconditions are corrected, the filters may beplugged or the RFS may be inoperative. Filtersmay be shaken by the operator initiative bypressing the filter button on the instrument panel ifthere is a failure in the RFS control system.

Successful operation of the RFS option requiresclean, undamaged filters. Plugged filters maycause the RFS to cycle continuously even at startup. The option also requires good sealing of theupper lid to the hopper, as well as a good sealbetween the two upper filter chambers.

It is recommended that the machine be driven forsome test sweeping with the RFS option at initialstart up. This next step assumes the hopper coverand upper filter chamber of the hopper wascleaned thoroughly prior to installation of the RFSoption. Sweep for 30 minutes and open thehopper cover to check the integrity of the seals.Look at the top of the shaker panels and theunderside of the hopper cover. Check for anysigns of dust tracking that may be caused by abad seal or filter. Repair a necessary. Perform thischeck periodically while using the sweeper withthe RFS option.

HYDRAULIC FLUID

The quality and condition of the hydraulic fluidplay a very important role in how well the machineoperates. TENNANT’s hydraulic fluid is speciallyselected to meet the needs of TENNANTmachines.

TENNANT’s hydraulic fluids provide a longer lifefor the hydraulic components. There are two fluidsavailable for different temperature ranges:

TENNANT part no. Ambient Temperature65869 above 7_ C (45_ F)65870 below 7_ C (45_ F)

The higher temperature fluid has a higherviscosity and should not be used at the lowertemperatures. Damage to the hydraulic pumpsmay occur because of improper lubrication.

The lower temperature fluid is a thinner fluid forcolder temperatures.

If another hydraulic fluid is used, make sure thespecifications match TENNANT’s hydraulic fluidspecifications. Using substitute fluids can causepremature failure of hydraulic components.

European marketed machines are filled withlocally available hydraulic fluids. Check the labelon the hydraulic fluid reservoir.

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 every 800 hours ofoperation 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 treatmentis not given immediately.

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