SAFETY INSTRUCTIONS

Personal protective equipment

IMPORTANT INFORMATION

Incorrect or careless use of a brush cutter, brushcutter or trimmer can turn it into a dangerous tool that can cause serious or even fatal injury to the operator or others. It is extremely important that you read and understand the content of this manual.

When using a brush cutter, brushcutter or trimmer, protective equipment approved by the appropriate authorities must be used. Personal protective equipment does not eliminate the risk of accidents, however, it can reduce the effects of an injury in the event of an accident. Ask your dealer for help when choosing protective equipment.

!WARNING!

Remove your hearing protection as soon as you stop the engine, so that you can hear any noises or warning signals.

HELMET

A helmet should be worn if trees to be cleared are higher than 2 metres.

EAR PROTECTION Ear protection offering

sufficient dampening effect should be used.

EYE PROTECTION Blows from branches or objects thrown by the rotating cutting equipment can damage the eyes.

GLOVES

Gloves should be worn when necessary, e.g., when assembling cutting equipment.

BOOTS

Use anti-slip and stable boots.

CLOTHING

Wear clothes made of a strong fabric and avoid loose clothing that can catch on shrubs and branches. Always wear heavy-duty long pants. Do not wear jewellery, shorts, sandals or go barefoot. Secure hair so it is above shoulder level.

FIRST AID KIT

A first aid kit should be carried by operators of brush cutters, brushcutters or trimmers.

The machine‘s safety equipment

This section describes the machine‘s safety equipment, its function and how checks and maintenance are carried out to ensure that it operates correctly. (See the chapter “What is what“ to locate where this equipment is positioned on your machine.)

!WARNING!

Never use a machine with defective safety equipment. Follow the control, maintenance and service instructions described in this section.

1. Throttle trigger lock

The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (A) is pressed into the handle (= when you hold the handle) the throttle

(B) is released. When the grip on the handle is released the throttle and the throttle trigger lock return to their original positions. This takes place via two independent return spring systems. This means that the throttle is automatically locked in its “idling“ position.

SAFETY INSTRUCTIONS

2. Stop switch

The stop switch should be used to stop the engine.

3. Cutting attachment guard

This guard is intended to prevent objects from being thrown towards the operator and to protect the operator from unintentionel contact with the cutting attachment.

!WARNING!

Do not attach any blade to the unit without proper installation of all required parts. Failure to use the proper parts can cause the blade to fly off and seriously injure the operator and/or bystanders.

Under no circumstances may the cutting equipment be used without an approved guard fitted. See the chapter “Technical data”. If the wrong guard or a defective guard is fitted this can cause serious personal injury.

4. Anti-vibration system

Your machine is equipped

with an anti-vibration system 142R that has been designed to give as vibration-free and

comfortable usage as possible.

The use of incorrectly wound cord or blunt, incorrect cutting equipment

(incorrect type or incorrectly 132R sharpened, see section “Filing

the blade”) increases the level of vibration.

The machine’s vibration damping system reduces the transfer of vibrations between the engine unit/ cutting equipment and the machine’s handle unit.

!WARNING!

Over exposure to vibrations can result in blood-vessel or nerve injury to persons suffering with blood circulation problems. Seek medical attention if you experience physical symptoms that can be related to over exposure to vibrations. Examples of such symptoms are “numbness“, lack of feeling, “tickling“, “pricking“, “pain“, lack of or a reduction in normal strength, changes in the colour of the skin or its surfaces. These symptoms normally appear in the fingers, hands or wrists.

5.Quick-release

There is an easily accessible, quick-release catch fitted to the chest as a safety precaution in the event of a fire in the engine or for any other situation that requires you to free yourself from the machine and harness. See the section “Adjusting the harness and brush cutter“.

English – 5

SAFETY INSTRUCTIONS

6. Muffler

The muffler is designed to give the lowest possible noise level and to direct the engine‘s exhaust fumes away from the operator.

In countries that have a warm and dry climate the risk of fire is obvious. We have therefore fitted certain mufflers with a spark arrest screen. Make sure that your muffler is fitted with this kind of screen.

It is extremely important that the instructions for checking, maintaining and servicing the muffler are followed. (See the section

“Control, maintenance and service of the machine‘s safety equipment“.)

!WARNING!

Bear in mind that exhaust fumes:

contain carbon monoxide, which can cause carbon monoxide poisoning. Therefore never start or run the machine indoors.

are hot and can contain sparks that can cause fires. Never start the machine indoors or close to inflammable material.

7. Cutting equipment

1)Clearing blades are intended for cutting wood.

2)Grass blades are intended for brush cutting.

3)The trimmer head is intended for trimming grass.

8. Locking nut

A locking nut is used to secure some types of cutting equipment on the output shaft.

SAFETY INSTRUCTIONS

Control, maintenance and service of the machine‘s safety equipment

IMPORTANT INFORMATION

All service and repairs to the machine require special training.

This applies especially to the machine‘s safety equipment. If the machine does not meet any of the controls listed below you should contact your service workshop.

The purchase of one of our products guarantees that professional repair and servicing will be carried out on it. If the point of purchase is not one of our servicing dealers, please ask for details of the closest service workshop.

1. Throttle trigger lock

Check that the throttle is locked in the “idling position“ when the throttle trigger lock is in its original position.

Press in the throttle trigger lock and make sure it returns to its original position when released.

Ensure that the throttle and throttle trigger lock move easily and that their return spring systems function.

The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (A) is pressed into the handle (= when you hold the handle) the throttle

(B) is released. When the grip on the handle is released the throttle and the throttle trigger lock return to their original positions. This takes place via two independent return spring systems. This means that the throttle is automatically locked in its “idling“ position.

A

B

See section "Start". Start the machine and apply full throttle. Release the throttle and check that the cutting equipment stops and remains at a standstill. If the cutting equipment rotates with the throttle in the idling position then the carburettor‘s idling setting must be checked. See chapter

“Maintenance“.

2. Stop switch

Start the engine and make sure that the engine stops when the stop switch is moved to the stop position.

SAFETY INSTRUCTIONS

6. Cutting equipment

This section describes how through correct maintenance and through using the right type of cutting equipment you can:

Reduce the machine‘s tendency to kickback

Obtain maximum cutting capacity.

Increase the service life of the cutting equipment.

Four basic rules:

1)Only use the cutting and guard equipment we recommend! See chapter “Technical data“.

2)Keep the blade‘s teeth well and correctly sharpened! Follow our instructions and use the recommended filing gauge. An incorrectly sharpened or damaged blade increases the risk of an accident.

3)Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.

7. Quick-release

• Check that the harness straps are correctly positioned. When the harness and machine are adjusted, check the harness‘ safety release catch to ensure it works correctly.

8. Locking nut

• Protect your hand from injury when assembling, use the blade guard as protection when tightening with a socket spanner. Tighten the nut by turning against the direction of rotation. Loosen the nut by turning in the direction of rotation. (NOTE! the nut has a left-hand thread).

Tighten the nut using a socket spanner, 35 - 50 Nm (3.5 - 5 kpm).

NOTE!

The locking nut‘s nylon lock must not be so worn that it can be turned by hand. The lock shall hold at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.

!WARNING!

Never use a machine with defective safety equipment. The safety equipment should be maintained as described in this section. If your machine does not meet any of these controls you should contact your service workshop.
