SAFETY INSTRUCTIONS

Personal protective equipment

IMPORTANT INFORMATION

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.

EYE PROTECTION

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

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.

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

(326HDA55/326HE3)

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

s handle unit.

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. These 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.

Mufﬂer

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!

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!

Cutter guard

(326HDA55)

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

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.

SAFETY INSTRUCTIONS

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 checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional 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

• See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked. See instructions under the heading Maintenance.

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 machine 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.

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

Stop switch

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

Hand guard

(326HDA55/326HE3)

• Check that the hand guard is ﬁtted correctly.

• Check that the hand guard is undamaged.

SAFETY INSTRUCTIONS

Vibration damping system

• Regularly check the vibration damping units for cracks or deformation.

• Check that the vibration damping element is undamaged and securely attached.

Mufﬂer

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.

• 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 then it should be cleaned regularly. A blocked mesh causes the engine to overheat, which can lead to serious damage.

Never use a mufﬂer with a defective spark arrestor mesh.

• 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.
