SAFETY INSTRUCTIONS

Personal protective equipment

IMPORTANT! Whenever you use the hedge trimmer you must use personal protective equipment that is approv ed by the authorities. Personal protective equipment does not eliminate the risk of injury, but it can reduce the degree of injury in the event of an accident. Ask your dealer for help when choosing equipment.

WARNING! Listen out for warning signals or shouts when you are wearing hearing

protection. Always remove your hearing protection as soon as the engine stops.

GLOVES Gloves must be worn when required, for e xample when ﬁtting,

inspecting or cleaning cutting attachments.

HEARING PROTECTION Wear hearing protection that provides adequate noise

reduction.

EYE PROTECTION Always wear approv ed e y e protection. If you use a visor then

you must also wear approved protective goggles. Approved protective goggles must comply with standard ANSI Z87.1 in the USA or EN 166 in EU countries. Visors must comply with standard EN 1731.

FIRST AID KIT Always have a ﬁrst aid kit nearby.

Machine ′ s safety equipment

This section describes the machine ′ s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the ”What is what?” section to locate where this equipment is positioned on your machine.

The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest service workshop.

WARNING! Never use a machine that has faulty safety equipment! Carry out the

inspection, maintenance and service routines listed in this section.

Throttle lock

The throttle lock is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lock both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting.

BOOTS Wear sturdy, non-slip boots.

CLOTHING Wear clothes made of a strong fabric and av oid loose clothing

that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level.

Stop switch

Use the stop switch to switch off the engine.

Hand guard

The hand guard prevents hands from coming into contact with the moving blades, for example, if the operator loses grip on the front handle.

SAFETY INSTRUCTIONS

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to minimise vibration and make operation easier.

The machine ′ of vibration between the engine unit/cutting equipment and the machine ′ blades, is suspended from the handle unit by ﬁve springs.

WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. The risk increases at low temperatures.

Mufﬂer

WARNING! The inside of mufﬂer contain chemicals that may be carcinogenic. Avoid

contact with these elements in the event of a damaged mufﬂer.

WARNING! Engine exhaust fumes contain carbon monoxide, which can cause carbon

monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated.

The exhaust fumes from the engine are hot and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

Checking, maintaining and servicing the machine ′

IMPORTANT! All servicing and repair work on the machine requires special training. This is especially true of the machine ′ s safety equipment. If your machine fails an y of the checks described below you must contact your service agent. When y ou buy any of our products we guar antee the availability of prof essional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your nearest service agent.

s safety equipment

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufﬂer ﬁtted with a catalytic converter is also designed to reduce harmful exhaust gases.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. We therefore ﬁt certain mufﬂers with a spark arrestor mesh. Check whether the mufﬂer on your machine is ﬁtted with this kind of mesh.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment.

WARNING! Never use a machine with faulty safety equipment. The machine’s safety

equipment must be checked and maintained as described in this section. If your mac hine fails any of these checks contact your service agent to get it repaired.

WARNING! Always stop the engine before doing any work on the cutting attachment.

This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.

Throttle lock

• Make sure the throttle control is locked at the idle setting when the throttle lock is released.

WARNING! Mufﬂers ﬁtted with catalytic converters get very hot during use and

remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of ﬁre!

• Press the throttle lock and make sure it returns to its original position when you release it.

SAFETY INSTRUCTIONS

• Check that the throttle control and throttle lock mov e freely and that the return springs work properly.

• See instructions under the heading Start. Start the hedge trimmer and apply full throttle. Release the throttle trigger and check that the blades stop and remain stationary. If the blades move when the throttle trigger is in the idle position then the carburettor idle setting must be adjusted. See instructions under the heading Maintenance.

Stop switch

• Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Mufﬂer

• Never use a machine that has a faulty mufﬂer.

• Regularly check that the mufﬂer is securely attached to the machine.

• If the mufﬂer on your machine is ﬁtted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. Ne v er use a m ufﬂer that has a def ectiv e spark arrestor mesh.

Hand guard

• Check that the hand guard is ﬁtted correctly.

• Check that the hand guard is undamaged.

Vibration damping system

• Regularly check the vibration damping units for crac ks or deformation.

• Make sure the vibration damping units are securely attached to the engine unit and handle unit.

Blades

To ensure good cutting results it is important that the contact pressure between the blades is correct. The contact pressure is adjusted by turning the screws on the underside of the bar clockwise as far as they will go. Then turn the screws anticlockwise a 1/4 turn. Loc k the screws using the locking nut on the top of the bar. Chec k that the screws are loose enough to allow the washers under the screw heads to slide sidew ays.

When the blades are correctly adjusted the play between the blades should be 0,2–0,4 mm, measured at the screws. The edges of the blades are too hard to be ﬁled. Dull blades should be sharpened using a grinder. Replace the blades if they are bent or damaged.
