GENERAL SAFETY PRECAUTIONS
Important
IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or
forestry clearing.
The only accessories you can operate with this engine unit are the cutting attachments we recommend in the section on Technical 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.
Never use the machine in extreme weather conditions such as severe cold, very hot and/
or humid climates.
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: Using an incorrect cutting attachment or an incorrectly
filed blade can increase the risk of accidents.
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! A clearing saw, brushcutter or trimmer can be dangerous if used incor-
rectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual. 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.
HELMET
A helmet should be worn if the brush being cleared is taller than 2 metres.
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.
5
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
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.
Make sure the throttle control is locked at the idle setting when the throttle lock is re-
leased.
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
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
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
Check 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.
Harness quick release
There is an easily accessible, harness quick release fitted at the front in case of an emergency that requires you to free yourself from the machine and harness.
See instructions under the heading Adjusting the harness.
Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.
Muffler
The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator.
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
Spark arrestor mesh
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.
7
GENERAL SAFETY PRECAUTIONS
Regularly check that the muffler is securely attached to the machine.
WARNING: Mufflers 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: Bear in mind that: Engine exhaust fumes contain car-
bon 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!
Locking nut
A locking nut is used to secure some types of cutting attachment.
When fitting, tighten the nut in the opposite direction to the direction of rotation of the
cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left--hand thread.) Tighten the nut using the socket spanner.
The |

not be so worn that you can turn it by |
|
hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.
Cutting equipment
This section describes how to choose and maintain your cutting equipment in order to: S Reduce the risk of blade thrust.
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 “Technical data”.
Refer to the instructions for the cutting attachment to check the correct way to load the trimmer line and the correct line diameter.
Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging. Maintain the correct blade setting! Follow our instructions and use the recommended file gauge.
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 lead from the spark plug before you start to work on it.
WARNING: Using an incorrect cutting attachment or an incorrect-
ly sharpened blade increases the risk of kickback.

GENERAL SAFETY PRECAUTIONS
Cutting equipment
Grass blades and grass cutters are intended for cutting coarse grass.
for trimming
grass.
Sharpening grass cutters and grass blades
S See the cutting attachment packaging for
correct sharpening instructions. Sharpen blades and cutters using a single--cut flat file.
S Sharpen all edges equally to maintain the balance of the blade.
General rules
Only use cutting attachments with the guards we recommend! See the section on Technical data.
Keep blade correctly sharpened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.
Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
WARNING: Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten
a twisted blade so that it can be reused. Only use original blades of the specified type.
Trimmer head
IMPORTANT!
Always ensure the trimmer line is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
SOnly use the recommended cutting attachments. See the section on “Technical data”.
SSmaller 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.
SThe length of the trimmer line is also important. 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.
STo 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.
