The machine’s protective equipment
This section describes the hedge trimmer’s protective equip-
ment, its function and how checks and maintenance are
carried out to ensure that it operates correctly. (See the chapter
”What is what” to locate where this equipment is positioned on
your machine.)
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 this
manual.
• When using a hedge trimmer, protective
equipment approved by the appropriate
authorities must be used. Personal protective
equipment does not eliminate the risk of
accidents, however, it can reduce the effects of an
injury in the event of an accident. Ask your dealer
for help when choosing protective equipment.
Personal protective eqipment
GLOVES
Gloves should be worn when
necessary, e.g., when
inspecting, cleaning or
assembling cutting equip-
ment.
EAR PROTECTION
Ear protection offering
sufficient dampening effect
should be used.
EYE PROTECTION
Blows from branches or
objects thrown by the
moving blades can damage
the eyes.
BOOTS
Use anti-slip and stable
boots.
CLOTHING
Wear clothes made of a
strong fabric and avoid loose
clothing that can catch on
shrubs and branches. Always
wear heavy-duty long pants.
Do not wear jewellery,
shorts, sandals or go bare-
foot. Secure hair so it is
above shoulder level.
FIRST AID KIT
A first aid kit should be close
at hand.
SAFETY INSTRUCTIONS
1. Throttle trigger lock
The throttle trigger lock is
designed to prevent the
throttle from accidentally
being engaged. The trigger
(A) can only be pressed in, if
the lock (B) is held in (= the
operator holding the
handle). When the grip on
the handle is released the
throttle and the throttle
trigger lock return to their
original positions. This
takes place via two indepen-
dent return spring systems.
This means that the throttle
is automatically locked in
the idling position.
2. Stop switch
The stop switch (C) should
be used to stop the engine.
3. Hand guard
The hand guard (D)
prevents the operator’s
hands from coming into
contact with the blades. For
example, if the operator
should loose his grip on the
front handle.
WARNING!
Never use a hedge trimmer with defective
protective equipment. Follow the control,
maintenance and service instructions
described in this section.
!
!
WARNING!
Remove your hearing protection as soon as
you stop the engine, so that you can hear
any noises or warning signals.

4. Vibration
damping system
The hedge trimmer is
equipped with a vibration
damping system, which is
designed to give as vibra-
tion-free and comfortable
use as possible.
The hedge trimmer’s
vibration damping system
reduces the transfer of
vibrations between the
engine/unit blades and the
hedge trimmer’s handles.
The engine body, including
the blades, is suspended on
the handlebar system by five
springs.
SAFETY INSTRUCTIONS
!
WARNING!
Over exposure to vibrations can result in
blood-vessel or nerve injury to persons
suffering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are ”numbness”, lack of
feeling, ”tickling”, ”pricking”, ”pain”, lack
of or a reduction in normal strength,
changes in the colour of the skin or its
surfaces. These symptoms normally appear
in the fingers, hands or wrists.
5. Muffler
The muffler is designed to
give the lowest possible noise
level and to direct the
engine‘s exhaust fumes away
from the operator. Muffler
fitted with catalytic con-
verter is also designed to
reduce harmful exhaust
components.
In countries that have a
warm and dry climate the
risk of fire is obvious. We
have therefore fitted certain
mufflers with a spark arrest
screen. Make sure that your
muffler is fitted with this
kind of screen.
It is extremely important
that the instructions for
checking, maintaining and
servicing the muffler are
followed. (See the section
“Control, maintenance and
service of the machine‘s safety
equipment“).
!
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping. This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
!
WARNING!
Bear in mind that exhaust fumes:
• contain carbon monoxide, which can
cause carbon monoxide poisoning.
Therefore never start or run the machine
indoors.
• are hot and can contain sparks that can
cause fires. Never start the machine
indoors or close to inflammable material.

SAFETY INSTRUCTIONS
WARNING!
Never use a machine with defective safety
equipment. The safety equipment should
be maintained as described in this
section. If your machine does not meet
any of these controls you should contact
your service workshop.
!
WARNING!
Always stop the engine before starting
work on any part of the cutting
equipment. This continues to rotate even
after the throttle has been released.
Ensure that the cutting equipment has
stopped completely and remove the cable
from the spark plug before you start to
work on it.

the hedge trimmer’s protective
equipment
2. Stop switch
• Start the engine and
make sure that the engine
stops when the stop
switch is moved to the
stop position.
3. Hand guard
• Ensure that the blade
guard is fitted correctly.
• Make sure the hand
guard is not damaged in
anyway.
4. Vibration
damping system
• Check the vibration
damping element
regularly for material
cracks and distortion.
• Check that the vibration
damping element is
securely attached
between the engine unit
and the handlebar unit.
IMPORTANT INFORMATION
• All service and repairs to the machine require
special training.
• This applies especially to the machine‘s safety
equipment. If the machine does not meet any of
he controls listed below you should contact
your service workshop.
• The purchase of one of our products
guarantees that professional repair and
servicing will be carried out on it. If the point of
purchase is not one of our servicing dealers,
please ask for details of the closest service
workshop.
1. Throttle trigger lock
• Check that the throttle is
locked in the “idling
position“ when the
throttle trigger lock is in
its original position.
• Press in the throttle
trigger lock and make
sure it returns to its
original position when
released.
• Ensure that the throttle
and throttle trigger lock
move easily and that their
return spring systems
function.
• See the section ”Start”.
Start the hedge trimmer
and apply full throttle.
Release the throttle and
check that the blades
stop and remain at a
standstill. If the blades
rotate with the throttle in
the idling position then
the carburettor’s idling
setting must be checked.
See chapter ”Mainte-
nance”.

SAFETY INSTRUCTIONS
5. Muffler
• Never use a machine that
has a defective muffler.
• Check regularly that the
muffler is secure.
• If your muffler is fitted
with a spark arrest screen
then it should be cleaned
regularly. A blocked
screen leads to the engine
overheating with serious
damage as a result. Never
use a muffler with a
defective spark arrest
screen.
6. Blades
To ensure good cutting
results it is important that
the contact pressure
between the blades is
correct.
The contact pressure
between the blades is
adjusted by tightening the
screws on the underside of
the bar as far as they will
go, then backing them off
1/4 turn. Lock the screws
using the locking nuts on
the top face of the bar.
The washers should still
slide freely under the
screw heads after the
screws have been tight-
ened.
The edges of the blade are
too hard to be filed. Dull
blades should be sharp-
ened using a grinder.
7. Blade guard
• Replace the blades if they
are bent or damaged.
