SAFETY INSTRUCTIONS
Personal protective equipment
IMPORTANT! Whenever you use a clear-
ing saw, brushcutter or trimmer you must
wear personal protective equipment that is
approved by the authorities. Personal
protective equipment does not eliminate
the risk of accidents, but it can reduce the
effects of an injury in the event of an accident. Ask your dealer for help when
choosing protective equipment.
WARNING: Listen out for warn-
ing signals or shouts when you are
wearing hearing protection. Always
remove your hearing protection as
soon as the engine stops.
GLOVES
Gloves should be worn when necessary,
e.g., when fitting 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.
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
“Know your trimmer ” 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 servicing dealer.
WARNING: Never use a machine
that has faulty safety equipment!
Carry out the inspection, maintenance and service routines listed in
this section.
Throttle lock--out
The throttle lock--out is designed to prevent
accidental operation of the throttle control.
When you press the lock --out (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--out 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.
A
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 jewelry, shorts
sandals or go barefoot. Secure hair so it is
above shoulder level.

SAFETY INSTRUCTIONS
Cutting attachment guard
This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator
from accidental contact with the cutting attachment.
WARNING: Never use a cutting
attachment without an approved
guard. See the section on “Techn ical
data”. If an incorrect or faulty guard
is fitted this can cause serious
personal injury.
Use of incorrectly wound trimmer line or an
incorrect cutting attachment increases the
level of vibration.
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 color or condition.
These symptoms normally appear
in the fingers, hands or wrists. The
risk increases at low temperatures.
Muffler
The muffler is designed to reduce the noise
level and to direct the exhaust gases away
from the operator.
CAUTION! Muffler is fitted with a catalytic
converter designed to reduce harmful exhaust gases.
For mufflers, it is very important that you follow the instructions on checking, maintaining, and servicing your machine.
See Check ing, maintaining and servicing the
machine’s safety equipment section.
WARNING: Mufflers fitted with
catalytic converters get very hot
duringuseandremainsoforsome
time after stopping. This also ap plies at idle speed. Contact can re sult in burns to the skin. Remember
theriskoffire!
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: 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 com bustible material!
Cutting equipment
A trimmer head is intended for trimming
grass.
Checking, maintaining and
servicing the machine’s
safety equipment
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 any of the 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.

at the idle setting when the throttle lock -out is released.
S Press the throttle lock--out and make

stops when you push and hold the stop
switch.
Cutting attachment guard

S Always use the recommended guard for
the cutting attachment you are using. See
section on “Technical data”.
Muffler
S See instructions under the section
“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 carburetor idle setting
must be checked. See instructions under
the section “Maintenance”.
115275126 Rev. 1 9/15/09
S Never use a machine that has a faulty
muffler.
S Regularly check that the muffler is securely
attached to the machine.
S The muffler on this unit is equipped with a
special spark arrestor mesh. The mesh
should be checked and, if necessary.

SAFETY INSTRUCTIONS
Cutting equipment
This section describes how to choose and
maintain your cutting equipment in order to:
S Obtain maximum cutting performance.
S Extend the life of cutting equipment.
General rules
:
Trimmer head
S Only use the recommended cutting at-
tachments. See the section on “Technical
data”.
1. Only use cutting attachments with the
guards we recommend! See the section
on “Technical Data”.
2. Check the cutting attachment for damage
or cracks. A damaged cutting attachment
should always be replaced.
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.
IMPORTANT!
This section describes how to choose and
maintain your cutting equipment in order to:
Obtain maximum cutting performance.
Extend the life of cutting equipment.
Only use cutting attachments with the guards
we recommend! See the section on
“T echnical data”.
Refer to the instructions for the cutting attachment to check the correct way to load the
trimmer line and the correct line diameter.
S Smaller machines generally require small
trimmer heads and vice versa. This is because when clearing using trimmer line
the engine must throw out the trimmer
line radially from the trimmer head and
overcome the resistance of the grass
being cleared.
S The length of the trimmer line is also im-
portant. A longer trimmer line requires
greater engine power than a shorter
trimmer line of the same diameter.
S Make sure that the cutter on the trimmer
guard is intact. This is used to cut the
trimmer line to the correct length.
S To increase the life of the trimmer line it
can be soaked in water for a couple of
days. This will make the line tougher so
that it lasts longer.
IMPORTANT!
Always ensure the trimmer line is wound
tightly and evenly around the drum, otherwise the machine will generate harmful
vibration.
WARNING: Always stop the en-
gine 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
lead from the spark plug before
you start to work on it.
