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.

Use main brush II Speed when picking up light litter. This will improve both litter pickup and hopper loading. Do not use the II Speed speed in dusty environments. The machine can dust and clog the hopper dust filter. Operate the main brush in the Normal 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.

Polypropylene 8-double Row Main Brush --

Gives superior pickup of sand, gravel, and paper litter. Retains its stiffness when wet, and can be used indoor or out. Not recommended for high-temperature debris.

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.

Nylon Patrol Main Brush -- Designed for sweeping large indoor or outdoor areas at higher speed. The patrol pattern gives excellent loading of light bulky debris (leaves and paper), while the nylon bristle gives long life.

Heavy Gauge Polypropylene 8-double Row

Main Brush -- Designed for sweeping outdoor areas. The stiffer bristles allow excellent loading of heavier bulky debris (leaves and paper litter).

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.

OPERATION

REGENERATIVE FILTER SYSTEM (RFS)

The Regenerative Filter System (RFS) is an option that alternately turns on the filter shaker motors when the filters need cleaning because of a build--up of dust or debris.

Normally the RFS does not require the operator to stop the machine to shake the filters during sweeping operation (except in extreme and severe dust environments). However, it is recommended that the filters are shaken at the operator’s initiative each time the hopper is dumped. This can be accomplished during transit to a dump sight. AVOID shaking the filters while hopper is in a rolled out position. To initiate a shaking cycle, press the filter button on the instrument panel.

See FILTER SHAKER SWITCH.

In very severe dust environments, the plugged filter indicator on the instrument panel may remain lit. When this occurs, it is recommended that the operator stop the machine and initiate one or two shake cycles to clear a possible plugged filter condition. After shaking, roll the hopper out to evacuate the dust tray. Resume sweeping operation.

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 above conditions are corrected, the filters may be plugged or the RFS may be inoperative. Filters may be shaken by the operator initiative by pressing the filter button on the instrument panel if there is a failure in the RFS control system.

Successful operation of the RFS option requires clean, undamaged filters. Plugged filters may cause the RFS to cycle continuously even at start up. The option also requires good sealing of the upper lid to the hopper, as well as a good seal between the two upper filter chambers.

It is recommended that the machine be driven for some test sweeping with the RFS option at initial start up. This next step assumes the hopper cover and upper filter chamber of the hopper was cleaned thoroughly prior to installation of the RFS option. Sweep for 30 minutes and open the hopper cover to check the integrity of the seals.

Look at the top of the shaker panels and the underside of the hopper cover. Check for any signs of dust tracking that may be caused by a bad seal or filter. Repair a necessary. Perform this check periodically while using the sweeper with the RFS option.

MAINTENANCE

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 for the hydraulic components. There are two fluids available for different temperature ranges:

TENNANT part no.

65869

65870

Ambient Temperature

above 7_ C (45_ F) 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 another hydraulic fluid is used, make sure the specifications match TENNANT’s hydraulic fluid specifications. Using substitute fluids can cause premature failure of hydraulic components.

European marketed 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 237 Nm (175 ft lb) plus enough torque to align the slotted nut and the shaft hole after the first 50-hours of operation, and every 800 hours there after.

ENGINE

COOLING SYSTEM

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

--34_ C (--30_ F) rating. The coolant level should be 25 to 50 mm (1 to 2 in) below the filler opening.

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 clamps if they no longer tighten properly. Replace hoses if they become hard, cracked, or swollen.

Check the radiator core exterior and hydraulic cooler fins 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.

Flush the radiator and the cooling system every

400 hours of operation, using a dependable cleaning compound.

Shake the dust filters before dumping the hopper and at the end of every work shift. Avoid shaking the filters while the hopper is in a rolled out position. Check and clean the dust filters every

50 hours of operation. Extremely dusty conditions may require more frequent cleaning of dust filters.

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

D

SHAKING -- Press the filter shaker switch.

D

AIR -- Blow compressed air through the dust filter from the inside. This may be done with the dust filter in the machine, or for more efficient cleaning remove the dust filter from the machine and the prescreen wrap from the filter element. Always wear eye protection when using compressed air.

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

D

WATER -- Remove the fabric presceen wrap from the filter element. Wash the prescreen wrap in a water and mild detergent solution.

Rinse the prescreen wrap until it is clean. Air dry the wet prescreen wrap; do not use compressed air. NEVER wash the filter element with water.
