GENERAL SAFETY PRECAUTIONS

Important

IMPORTANT! The machine is only designed

for trimming grass.
The only accessories you can operate with
this engine unit are the cutting attachments
we recommend in the chapter on T echnical
data.
Never use the machine if you are tired, if you
have drunk alcohol, or if you are taking medi­cation that could affect your vision, your
judgement or your co--ordination.
Wear personal protective equipment. See in­structions under the heading Personal
protective equipment.
Never use a machine that has been modified
in any way from its original specification.
Never use a machine that is faulty. Carry out
the checks, maintenance and service instruc­tions described in this manual. Some mainte­nance and service measures must be carried
out by trained and qualified specialists. See
instructions under the heading Maintenance.
All covers and guards must be fitted before
starting. Make sure the spark plug cap and
lead are not damaged. Otherwise you could
get an electric shock.
The machine operator must ensure that no
people or animals come closer than 15
metres while working. When several opera­tors are working in the same area, the safety
distance should be at least 15 metres.

WARNING: This machine pro-

duces an electromagnetic field
during operation. Under some cir­cumstances, this field may interfere
with active or passive medical
implants. To reduce the risk of
serious or fatal injury, we recom­mend persons with medical
implants to consult their physician
and the medical implant manufac­turer before operating this machine.

WARNING: Never allow children

to use or be in the vicinity of the
machine. As the machine is equipped
with a spring--loaded stop switch and
can be started by low speed and
force on the starter handle, even
small children under some circum­stances can produce the force neces­sary to start the machine. This can
mean a risk of serious personal inju­ry. Therefore remove the spark plug
cap when the machine is not under
close supervision.

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.

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 EN
166 in EU countries.

GLOVES

Gloves should be worn when necessary,
e.g., when fitting cutting attachments.

BOOTS

Wear anti--slip and stable boots.

GENERAL SAFETY PRECAUTIONS

CLOTHING

Wear clothes made of a strong fabric and
avoid loose clothing that can catch on
shrubs and branches. Always wear heavy,
long pants. Do not wear jewelry, shorts
sandals or go barefoot. Secure hair so it is
above shoulder level.

FIRST AID KIT

A first aid kit should be carried by opera­tors of clearing saws, brushcutters or trim­mers.

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.

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.

WARNING: Never use a machine

that has faulty safety equipment!
Follow the control, maintenance
and service instructions described
in this section. If your machine fails
any of these checks contact your
service agent to get it repaired.

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
throttlecontrol(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.

115299326 Rev. 2 7/15/10

A

B

Make sure the throttle control is locked at
the idle setting when the throttle lock--out is
released.

Press the throttle lock--out and make sure it
returns to its original position when you re­lease it.

Check that the throttle control and throttle
lock--out move freely and that the return
springs work properly.

See instructions under the heading 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
carburettor idle setting must be checked.
See instructions under the heading
Maintenance.

GENERAL SAFETY PRECAUTIONS

Stop switch

Make sure the engine stops when you push
and hold the stop switch.

Cutting attachment guard

Muffler

The muffler is designed to reduce the noise
level and to direct the exhaust gases away
from the operator.
CAUTION! Muffleris fitted with a catalytic
convertic designed to reduce harmful ex­haust gases.

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.

Check that the guard is undamaged and not
cracked. Replace the guard if it has been
exposed to impact or is cracked.
Always use the recommended guard for the
cutting attachment you are using. See the
“Technical data” section.

WARNING: Never use a cutting

attachment without an approved
guard. See the section on “Technical
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.

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.

Muffler bolts

For mufflers, it is very important that you
follow the instructions on checking, main­taining, and servicing your machine.
Never use a machine that has a faulty
muffler.

Regularly check that the muffler is securely
attached to the machine.

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!

GENERAL SAFETY PRECAUTIONS

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 com­bustible material!

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.

IMPORTANT!

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.

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.

Trimmerhead

IMPORTANT!

Always ensure the trimmer line is wound
tightly and evenly around the drum, other­wise the machine will generate harmful
vibration.

S Only use the recommended cutting at-

tachments. See the section on “Technical
data”.

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.

WARNING: A faulty cutting at-

tachment may increase the risk of
accidents.
