1 Safety Instructions

Before commissioning, please read the

operating instructions and note:

Warning

symbol

This symbol has been used throughout

these operating instructions to highlight

all sections relevant to your safety. Also

pass on all safety instructions to other

users.

Intended use

The machine meets the current state of

the art and complies with the applicable

safety regulations at the time of market-

ing within the context of the approved

use. In terms of design it was not possi-

ble to eliminate either the foreseeable

misuse or the remaining risk without

limiting the functionality in accordance

with the regulations.

The weed brush type 8100, including the

attachments approved by the manufac-

turer, is intended for uprooting and de-

positing weed growth on pavement,

concrete and/or asphalt surfaces so that

the weed can be collected in a further

operation if necessary (intended use).

Any other use is considered to be con-

trary to the intended purpose. The man-

ufacturer is not liable for any damages

resulting from such use and the risk is

entirely the user's own.

Intended use also includes observance

of the operating, servicing and mainte-

nance conditions stipulated by the man-

ufacturer.

Unauthorized changes to the machine,

especially to the safety equipment, may

lead to increased levels of danger, which

would rule out any manufacturer liability

for resulting damage.

When using the machine on public roads

– and when being transported – the

national road traffic regulations of the

relevant country must be complied with

(marking, lighting, etc.).

The machine must be operated as di-

rected in the operating instructions.

Other operators must given instruction if

required.

Any improper use or execution of activi-

ties at the machine not described in

these instructions constitutes unauthor-

ized misuse and is not within the statuto-

ry limits for liability of the manufacturer.

Improper use of the machine can en-

danger people and may result in dam-

age to the machine or other property of

the operator. It can also impair the func-

tionality of the machine.

3 Devices and Operating Elements

The Weed brush agria 8100 is suitable

for uprooting and depositing weed

growth on pavement, concrete and/or

asphalt surfaces so that weeds can be

collected in a further operation if neces-

sary.

When using the weed brush on public

roads - e. g. during transport - the regu-

lations of the national road traffic regula-

tions must be observed (such as mark-

ing, lighting).

The implements released in the Agria

sales list are available.

Petrol engine

The four-stoke petrol engine is to be

used with standard petrol (see chapter

Startup, page 23).

During the first 20 hours of operation

(running-in period) do not use the engine

at full power.

The rule of never using the engine at a

higher speed than necessary for the

work in hand applies even after the

running-in period.

High speeds are detrimental to

all engines and significantly reduce

their service life. This especially ap-

plies for no-load operation! Over-

revving the engine (letting it roar) can

result in immediate damage.

Cooling

The engine is cooled with an air blower.

Keep the fan grille at the cable-pull

starter and the cooling fins of the cylin-

der free of dirt and aspirated plant de-

bris.

Idling

Always ensure that the engine idle

speed is adjusted correctly. With speed

regulating lever at idling, the engine

should continue running smoothly.

- agria-Service -

Air filter

The air filter cleans the aspirated air. A

contaminated filter reduces the engine

output.

Ignition system

The petrol engine is equipped with a

contactless electronic ignition system.

We recommend that any necessary

inspections are carried out by a skilled

person only.

Speed regulating lever

Use the speed regulating lever (A/4) on the

ste

ering bar to continuously adjust the engine

speed between min = IDLE and max = FULL

THROTTLE as required.

Safety circuit

For traction drive and brush drive, the weed

brush is equipped with a safety/clutch lever (A/2

or A/3).

• Stop position:

The related drive is switched

off when you release the levers (A/2 or A/3).

The engine continues running.

• Operating position:

To operate the ma-

chine, press down the levers (A/2/A/3). This

establishes a non-

positive connection be-

tween motor and gearbox.

The safety circuit must be operated in two steps:

1) Pull the locking strap (unlatch)

2) Actuate the safety/clutch lever downwards.

Never tamper with the safety circuit.

Never tie up the safety lever.

The safety circuit is also used as

emer-

gency off switch:

Release the lever in a dang

erous situation. It

swings automatically to the "STOP" position!

Engine stop switch

The electric e

ngine stop switch (B/14) switches

the ignition system ON/OFF.

"I" = operating position

"O" = engine stop position

3

Devices and Operating Elements

18

Weed brush agria 8100

Clutch

A cone clutch is installed for both traction drive

and brush drive. Pressing down the levers actu-

ates the clutches: (A/3) for the traction drive and

(A/2) for the brush drive. The levers automatical-

ly swing to the "0" position (disen

gaged) when

you release them. Either clutch can be operated

separately.

In order to prevent the clutch from slipping dur-

ing work, a clearance of 1 - 2

mm is set at the

hand lever at the factory. Check the clutch play

after the first hour of Operation. Adju

st it if nec-

essary (see Maintenance and Care).

Note:

Park the weed brush only when the

drives

are switched off (see section Storage on

page 42

). Failure to do so can cause clutch

problems.

Forward / reverse gears

The weed brush is equipped with a forward gear

and a reverse gear.

The direction of the arrow on the rocker (A/18)

corresponds to the direction of travel.

Press the rocker switch left or right forwards.

The neutral position 0 is between forward and

reverse.

Steering bar

Adjust the steering bars only when trac-

tion drive and brush drive

drive are switched

off - risk of accident!

Steering bar height adjustment

•

Press the notch lever (A/20) down until the

notches are released.

• Move the handlebar to the required level.

•

Release the notch lever and ease the han-

dlebar in a notch so that the n

otch lever

swings fully up to its home position.

Driving wheels

The drive wheels are secured to

the wheel shaft

with lynch pins (A/16) which makes it possible to

attach and remove the wheels.

3

Devices and Operating Elements

20

Weed brush agria 8100

Adjusting the brush head

The brush head can be adjusted about two different axes:

1. Horizontal longitudinal axis of the machine with two clamping screws (A/13)

2. Horizontal transverse axis of the machine with two clamping screws (A/11)

Recommended settings:

1) Tilt the brush head by approx. 5-

6° to the right

in the direction of travel:

• Release both clamping screws (A/13)

• Turn brush head to the right accordingly

•

Tighten both clamping screws again with

maximum hand force.

2) Tilt the brush head slightly forward:

• Release both clamping screws (A/11)

• Tilt the brush head forward

•

Tighten both clamping screws again with

maximum hand force.

With these settings, fatigue-free and low

-

vibration working is possible.

Any deviations from this (e. g. brush with too much forward inclination)

can lead to stronger vibrations on the steering bar or to greater lateral forces.

With the described setting, a weed strip of approx. 5-7 cm width is processed on the

right-hand side of the machine.

Wide-spread weed growth can be easily processed with swivelling motions on the

implement handle, and the same implement settings.

Allow the brush to act on the ground with moderate pressure only. Too high a con-

tact pressure increases the vibrations and the lateral forces on the steering bar.

Do not increase the brush pressure if the working result is poor. Rather go over the

same section again if necessary.
