SAFETY INSTRUCTIONS
Personal protective equipment
IMPORTANT! 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! 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.
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.
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.
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 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
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 vibration damping system reduces the transfer
′
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.
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.
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! 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!
Cutter guard (325HDA55)
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.
The blade guard (A) is intended to protect against any part of
the body coming into contact with the blades (B).

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.

s safety
• 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
(325HDA55,325HE3)
• Check that the hand guard is fitted correctly.
• Check that the hand guard is undamaged.
• 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.
Vibration damping system
• Regularly check the vibration damping units for cracks or
deformation.
• Check that the vibration damping element is undamaged
and securely attached.

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.
Cutter guard
(325HDA55)
• 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.
