SAFETY INSTRUCTIONS
Personal protective equipment
IMPORTANT! You must use approved personal protective
equipment whenever you use the machine. Personal
protective equipment cannot eliminate the risk of injury but
it will reduce the degree of injury if an accident does
happen. Ask your dealer for help in choosing the right
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 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 ′ 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.

s safety equipment
WARNING! Never use a machine that has
faulty safety equipment! Carry out the
inspection, maintenance and service
routines listed in this section.
Throttle lock
EYE PROTECTION
Always wear approved eye 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.
BOOTS
Wear sturdy, non-slip boots.
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.
Stop switch
Use the stop switch to switch off the engine.
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.

SAFETY INSTRUCTIONS
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.
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
The machine ′ s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine ′ s handle unit.
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!
WARNING! The inside of the muffler contain
chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a
damaged muffler.
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
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
WARNING! Bear in mind that:
!
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).
A muffler fitted with a catalytic converter is also designed to
reduce harmful exhaust gases.
