SWEEPING AND BRUSH INFORMATION

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

Plan the sweeping 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. Sweep as straight a path as possible. Avoid bumping into posts or scraping the sides of the sweeper. Overlap the brush paths.

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.

Speed up the engine to (Fast 2) when picking up light litter. This will improve both litter pickup and hopper loading. Do not use the (Fast 2) speed in dusty environments. The machine can dust and clog the hopper dust filter. Operate the engine in the (Fast 1) position when picking up general debris.

For best results, use the correct brush type for your sweeping application. The following are recommendations for main and side brush applications.

Nylon 8-double Row Main Brush --

Recommended for general sweeping, and has good hopper loading. Nylon has the longest life of the bristle types. Use this brush for sweeping rough or irregular surfaces.

Polypropylene and Wire 8-double Row Main

Brush -- The wire bristles loosen slightly packed soilage and heavier debris. The polypropylene bristles sweep up the debris with excellent hopper loading.

Crinkle Wire 8-double Row Main Brush -- The stiff wire bristles cut through compacted grime, hard to sweep dirt, and dirt mixed with oil, grease, or mud. This brush is recommended for foundry sweeping where heat may melt synthetic bristles.

This brush has good hopper loading ability, but is not recommended for dusty applications.

Nylon 24-row Main Brush -- Recommended for severe dust conditions on rough surfaces. This brush has excellent pickup and long life.

Fiber and Wire 24-row Main Brush -- Offers good sweeping action and pickup in heavy dust concentrations. This brush is recommended where soilage is slightly encrusted. The brush is not recommended for heavy buildup or hard packed soilage.

Polypropylene Side Brush -- A good general purpose brush for sweeping of light to medium debris in both indoor and outdoor applications.

This brush is recommended when bristles may get wet.

Nylon Side Brush -- A longer life, general purpose brush that is recommended for rough surfaces.

Flat Wire Side Brush -- Recommended for outside and curb-side sweeping where soilage is heavy or compacted. The stiff wire bristles dig out soilage. This brush is also recommended for foundry sweeping where heat may melt synthetic bristles.

HYDRAULICS

HYDRAULIC FLUID RESERVOIR

The reservoir is located in the engine compartment next to the radiator.

Mounted on top of the reservoir is a filler cap with a fluid level dipstick. The reservoir also has a hydraulic breather located next to the filler cap.

Replace the hydraulic breather after every 800 hours of operation.

Check the hydraulic fluid level at operating temperature every 100 hours of operation. Make sure the hopper is down when checking hydraulic fluid level. The end of the dipstick is marked with

FULL and ADD levels to indicate the level of hydraulic fluid in the reservoir.

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

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

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

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

The reservoir has a built-in strainer outlet that filters hydraulic fluid before it enters the system.

Replace the strainer every 800 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.

6600D 330890 (4--03)

TENNANT’s hydraulic fluids provide a longer life for the hydraulic components. There are two fluids available 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 higher viscosity and should not be used at the lower temperatures. Damage to the hydraulic pumps may occur because of improper lubrication.

The lower temperature fluid is a thinner fluid for colder temperatures.

If a locally-available hydraulic fluid is used, make sure the specifications match TENNANT hydraulic fluid specifications. Using substitute fluids can cause premature failure of hydraulic components.

European manufactured machines are filled with locally available hydraulic fluids. Check the label on the hydraulic fluid reservoir.

ATTENTION! Hydraulic components depend on system hydraulic fluid for internal lubrication. Malfunctions, accelerated wear, and damage will result if dirt or other contaminants enter the hydraulic system.

HYDRAULIC HOSES

Check the hydraulic hoses every 800 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.

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

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

PROPELLING MOTOR

Torque the shaft nut to 270 Nm (200 ft. lb) after the first 50-hours of operation, and every 800 hours there after.

COOLING SYSTEM

Check the radiator core exterior for debris every

100 hours of operation. Blow or rinse all dust, which may have collected on the radiator, in through the grille and radiator fins, opposite the direction of normal air flow. The grille and hydraulic cooler open for easier cleaning. Be careful not to bend the cooling fins when cleaning.

Clean thoroughly to prevent the fins becoming encrusted with dust. Clean the radiator and cooler only after the radiator has cooled to avoid cracking.

FOR SAFETY: When servicing machine, wear eye and ear protection when using pressurized air or water.

Check the radiator coolant level every 100 hours of operation. Use clean water mixed with a permanent-type, ethylene glycol antifreeze to a

--34 _ C (--30 _ F) rating.

FOR SAFETY: When servicing machine, avoid contact with hot engine coolant.

Check the radiator hoses and clamps every

200 hours of operation. Tighten the clamps if they are loose. Replace the hoses and clamps if the hoses are cracked, harden, or swollen.

Flush the radiator and the cooling system every

800 hours of operation, using a dependable cleaning compound.

6600D 330890 (3--08)

AIR FILTER INDICATOR

The air filter indicator shows when to replace the air filter element. Check the indicator daily. The indicator’s red line will move as the air filter element fills with dirt. Do not replace the air filter element until the red line reaches

5 kPa (20 in H

O) and the “SERVICE WHEN

RED” window is filled with red. The indicator’s red line may return to a lower reading on the scale when the engine shuts off. The red line will return to a correct reading after the engine runs for a while.

Reset the air filter indicator by pushing the reset button on the end of the indicator after replacing the air filter element.

AIR FILTER

The engine air filter housing has a dust cap and a dry cartridge-type air filter element. Empty the dust cap daily. The air filter must be replaced whenever the filter element is damaged or when the air filter indicator shows a restriction. The air filters cannot be cleaned.

The machine is also equipped with a heavy duty air filter safety element. It is inside the standard element. Replace this element after the primary filter has been damaged or changed three times.

Typical diesel fuel systems require priming to remove pockets of air in the fuel lines and fuel components. This is usually required after running out of fuel, changing fuel filter elements or repairing a fuel system component. Air in the fuel system prevents smooth engine operation.

This fuel system however is self-priming. The return line comes from the top of the injector which causes all air to escape through the return line.

MAINTENANCE

6600D 330890 (4--03)

MAINTENANCE

BATTERY

The battery for the machine is a low maintenance battery. Do not add water to the battery or remove the battery vent plugs.

After the first 50 hours of operation, and every

800 hours after that, clean and tighten the battery connections.

For Safety: When servicing machine, avoid contact with battery acid.

BELTS AND CHAINS

ENGINE FAN BELT

The engine fan belt is driven by the engine crankshaft pulley and drives the engine fan and alternator pulleys. Proper belt tension is obtained when the belt deflects 7 to 9 mm (0.28 to 0.35 in) from a force of 10 kg (22 lb) applied at the mid-point of the longest span.

Check and adjust the belt tension every 100 hours of operation.

WARNING: Moving belt and fan. Keep away.

STATIC DRAG CHAIN

A static drag chain prevents the buildup of static electricity in the machine. The chain is attached to the machine by a rear main brush skirt retaining bolt.

Make sure the chain is touching the floor at all times.

DEBRIS HOPPER

HOPPER DUST FILTER

The dust filter filters the air pulled up from the hopper. The dust filter is equipped with a shaker to remove the accumulated dust particles. The dust filter shaker is operated by the filter shaker switch.

The standard dust filter works very well for normal sweeping applications. The synthetic filter works well for humid or wet applications. The surface load filter works well for heavy fine dust applications. It keeps the dust on the outer surface of the filter, making filter shaking more effective.

Shake the dust filter before emptying the hopper and at the end of every work shift. Check and clean or replace the dust filter every 100 hours of operation.

To clean the dust filter, use one of the following methods:

D SHAKING -- Press the filter shaker switch.

TAPPING -- Tap the filter gently on a flat surface with the dirty side down. Do not damage the edges of the filter element or the filter will not seat properly in the filter frame.

D AIR -- Always wear eye protection when using compressed air. Blow air through the dust filter opposite the direction of the arrows. Never use more than 690kPa (100 psi) of air pressure and never closer the 50 mm (2 in) away from the filter. This may be done with the dust filter in the machine.

FOR SAFETY: When servicing machine, wear eye and ear protection when using pressurized air or water.

D WATER -- Rinse the synthetic filter with a low pressure garden hose through the dust filter opposite the direction of the arrows.

Both the standard and surface load dust filters can also be rinsed, but the filters will degrade with each rinsing and should be replaced after rinsing five times.

NOTE: Be sure the dust filter is dry before reinstalling it in the machine.
