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.

Speed up the engine to (Fast 2) when picking uplight litter. This will improve both litter pickup andhopper loading. Do not use the (Fast 2) speed industy environments. The machine can dust andclog the hopper dust filter. Operate the engine inthe (Fast 1) position when picking up generaldebris.

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

Nylon 8-double Row Main Brush --Recommended for general sweeping, and hasgood hopper loading. Nylon has the longest life ofthe bristle types. Use this brush for sweepingrough or irregular surfaces.

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.

Crinkle Wire 8-double Row Main Brush -- Thestiff wire bristles cut through compacted grime,hard to sweep dirt, and dirt mixed with oil, grease,or mud. 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.

07817

OPERATION

496500 330270 (9--01)

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

Fiber and Wire 24-row Main Brush -- Offersgood sweeping action and pickup in heavy dustconcentrations. This brush is recommendedwhere soilage is slightly encrusted. The brush isnot recommended for heavy buildup or hardpacked soilage.

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.

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

TENNANT part no. Ambient Temperature

65869 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 a locally-available hydraulic fluid is used, makesure the specifications match TENNANT hydraulicfluid specifications. Using substitute fluids cancause premature failure of hydraulic components.

European manufactured 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.

If you discover a fluid leak, contact yourmechanic/supervisor.
