SAFETY INSTRUCTIONS

Personal protective equipment

IMPORTANT! Incorrect or careless use of a hedge trimmer can turn it into a dangerous tool that can cause serious or even fatal injury. It is extremely important that you read and understand the contents of this operator’s manual. Whenever you use the hedge trimmer you must use personal protective equipment that is approved 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! Remove your hearing protection as soon as you stop the engine, so that you

can hear any noises or warning signals.

GLOVES

Gloves must be worn when required, for example when ﬁtting, inspecting or cleaning cutting attachments.

HEARING PROTECTION

Wear hearing protection that provides adequate noise reduction.

FIRST AID KIT

Always have a ﬁrst aid kit nearby.

Machine

This section describes the machine 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.

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.

EYE PROTECTION

Blows from branches or objects thrown by the moving blades can damage the eyes.

BOOTS

Wear sturdy, non-slip boots.

CLOTHING

Wear clothes made of a strong fabric and avoid 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 on the handlebar system via a four 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.

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!

Blade guard

The blade guard (A) is intended to protect against any part of the body coming into contact with the blades (B).

Mufﬂer

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! 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!

s safety equipment

• 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.

Hand guard

Throttle lock

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

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

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

• 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 cracks or deformation.

SAFETY INSTRUCTIONS

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. Never use a mufﬂer with a defective spark arrestor mesh.

Blade guard

• Check that the blade guard is not damaged or distorted.

• Replace the blade guard if it is bent or damaged.

Gear housing

• The gear housing gets hot when the machine has been in use. To avoid burning yourself do not touch the gear housing.

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. Lock the screws using the locking nut on the top of the bar. Check that the screws are loose enough to allow the washers under the screw heads to slide sideways.

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.

Starting

Fuel safety

• Always use a fuel container with an anti-spill valve.

• Never refuel the machine while the engine is running. Always stop the engine and let it cool for a few minutes before refuelling.

• Make sure there is plenty of ventilation when refuelling or mixing fuel (gasoline and 2-stroke oil).

• Move the machine at least 3 m from the refuelling point before starting it.

• Never start the machine:

1 If you have spilt fuel on it. Wipe off the spillage and allow

remaining fuel to evaporate.

2 If you have spilt fuel on yourself or your clothes, change

your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3 If the machine is leaking fuel. Check regularly for leaks

from the fuel cap and fuel lines.

4 Avoid all skin contact with fuel. Fuel is a skin irritant and

may even cause skin changes.

• The complete clutch cover and gear housing must be ﬁtted before the machine is started, otherwise the clutch may come loose and cause personal injury.

• Never start the machine indoors. Exhaust fumes can be dangerous if inhaled.

• Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.

• Place the machine on the ground, ensure the cutting attachment is clear of twigs and stones. Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot). Then grip the starter handle with your right hand and pull the starter cord.

Transport and storage

• Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked ﬂames, for example, from electrical machinery, electric motors, electrical relays/switches or boilers.

• When storing and transporting fuel always use approved containers intended for this purpose.

• When storing the machine for long periods the fuel tank must be emptied. Contact your local gas station to ﬁnd out where to dispose of excess fuel.

• The transport guard must always be ﬁtted to the cutting attachment when the machine is being transported or in storage.

• Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

WARNING! Take care when handling fuel. Bear in mind the risk of ﬁre, explosion and

inhaling fumes.
