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 engine air filter indicator.

-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.

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 engine speed when

picking up light litter. This will improve both litter

pickup and hopper loading. Do not use the Fast

engine speed in dusty environments. The

machine can dust and clog the hopper dust filter.

Operate the engine in the Medium engine speed

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

6650 330910 (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.

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.

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

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.
