SAFETY INSTRUCTIONS

Personal protective equipment

IMPORTANT INFORMATION

• Incorrect or careless use of a clearing saw, 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 clearing saw , 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!

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 clearing saws, brushcutters or trimmers.

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

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.

4 – English

SAFETY INSTRUCTIONS

2. Stop switch

The stop switch should be used to stop the engine.

4. Anti-vibration system

Your machine is equipped with an anti-vibration system 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 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.

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

data”

. If the wrong guard or a defective guard is fitted this can cause serious personal injury.

“Technical

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 clearing saw“.

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. Muffler fitted with catalytic converter is also designed to reduce harmful exhaust components.

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!

Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!

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.

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.

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)Keep the correct setting. Follow our instructions and use the recommended setting tool. An incorrectly set blade increases the risk of jamming and kickback.

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).

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

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 y our machine does not meet any of these controls you should contact your service workshop.

SAFETY INSTRUCTIONS

Cutting equipment

IMPORTANT INFORMATION The section describes how through correct mainte-

nance and through using the right type of cutting equipment you can reduce the machine‘s tendency to kickback, obtain maximum clearing capacity and increase the service life of the cutting equipment.

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

• Refer to the instructions for the cutting equipment for the correct winding of cord and for the selection of the right cord diameter.

• Keep the blade’s teeht well and correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.

• Maintain the correct setting. Follow our instructions and use the recommended filing gauge.

WARNING! Incorrect cutting equipment or an

Sharpening the clearing blade

• See the cutting equipment’s packaging for correct filing instructions.

• A correctly sharpened blade is a prerequisite for working efficiently and to avoid unnecessary wear to the blade and clearing saw.

incorrectly sharpened blade increases the risk of kickback.

Sharpening the grass blade

• See the cutting equipment’s packaging for correct filing instructions.

• The blades are sharpened using a single cut flat file.

• Sharpen all edges equally to maintain the balance of the blade.

Trimmer head

• Only use a trimmer head and trimmer cord that is recommended. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the cutting equipment we recommend! See chapter

“Technical data“.

• Generally smaller machines require a small trimmer head and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and also meet resistance from the grass being cleared.

• Make sure that the blade is well supported when you use the file. Use a 5,5 mm round file with a file holder.

• The sharpening angle is 15°. Every other tooth is sharpened to the right and the intermediate tooth to the left. When the blade has been heavily pitted by stones the upper side of the teeth can, in exceptional cases, need to be dressed using a flat file. In such cases this takes place before sharpening with the round file. Dressing the top side must be carried out equally for all teeth.

• Adjust the setting. This should be 1 mm.

• The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

• Make sure the knife positioned on the trimmer guard is intact. This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in water for a few days. This will make the line tougher and it will keep longer.

IMPORTANT INFORMATION Always ensure the trimmer cord is wound tightly

and evenly around the drum, otherwise harmful vibrations will occur.

WARNING!

Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it.
