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.

!

s vibration damping system reduces the transfer

s handle unit. The engine body, including the

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.
