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.

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.

HYDRAULICS

HYDRAULIC FLUID RESERVOIR

The reservoir is located in the enginecompartment next to the radiator.

Mounted on top of the reservoir is a filler cap witha fluid level dipstick. The reservoir also has ahydraulic breather located next to the filler cap.Replace the hydraulic breather after every 800hours of operation.

Check the hydraulic fluid level at operatingtemperature every 100 hours of operation. Makesure the hopper is down when checking hydraulicfluid level. The end of the dipstick is marked withFULL and ADD levels to indicate the level ofhydraulic fluid in the reservoir.

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

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.

Drain and refill the hydraulic fluid reservoir withnew hydraulic fluid every 800 hours of operation.

The hydraulic fluid filter is located at the bottom ofthe engine compartment. Replace the filterelement every 800 hours of operation.

The reservoir has a built-in strainer outlet thatfilters hydraulic fluid before it enters the system.Replace the strainer every 800 hours of operation.

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.

08007

07750

08051

MAINTENANCE

656550 330310 (5--98)

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.
