HOW THE MACHINE WORKS

The steering wheel controls the direction of

machine travel. The directional pedal controls the

speed and forward/reverse direction. The brake

pedal slows and stops the machine.

The side brush sweeps debris into the path of the

main brush. The main brush sweeps debris from

the floor into the hopper. The vacuum system

pulls dust and air through the hopper and the

hopper dust filter.

When sweeping is finished, clean the hopper dust

filter and empty the hopper.

PRE-OPERATION CHECKLIST

-Check the engine oil level.

-Check the engine coolant level.

-Check the radiator and hydraulic cooler fins

for debris.

-Check the hydraulic fluid level

-Check the skirts and seals for damage and

wear.

-Check the condition of the sweeping

brushes. Remove any string, banding,

plastic wrap, or other debris wrapped

around them

-Check the sweeping brush patterns for

adjustment.

-Check the condition of the hopper dust filter

and seals. Clean as required.

-Check the brakes and steering for proper

operation.

-Check the fuel level.

-Check the service records to determine if

maintenance is needed.

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

Crinkle Wire 8-double Row Main Brush -- T h e

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.

OPERATION

6600D 330890 (4--03)

Nylon24-rowMainBrush-- 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.

MAINTENANCE

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

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

-- 3 4 _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

FUEL FILTER

The fuel filter cartridge filters impurities from the

fuel. It is located on the left side of the engine.

Replace the fuel filter element every 400 hours of

operation.

FOR SAFETY: When servicing machine,

keep flames and sparks away from fuel

system service area. Keep area well

ventilated.

FUEL PIPES

Check the fuel pipes every 50 hours of operation.

If the clamp band is loose, apply oil to the screw

of the band, and securely tighten the band.

Made of rubber, the fuel pipes become worn out

whether the engine has been used much or not.

Replace the fuel pipes and clamp bands every

two years.

If the fuel pipes and clamp bands are found worn

or damaged before two years’ time, replace or

repair them at once. Bleed the fuel system after

replacement of any of the fuel pipes, see TO

PRIME THE FUEL SYSTEM. When the fuel pipes

are not installed, plug both ends with clean cloth

or paper to prevent dirt from entering the pipes.

Dirt in the pipes can cause fuel injection pump

malfunction.

PRIMING FUEL SYSTEM

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.

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:

DSHAKING -- Press the filter shaker switch.

DTAPPING -- 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.

DAIR -- 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.

DWATER -- 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.
