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. 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. Stop switch Use the stop switch to switch off the engine. 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. IMPORTANT! 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. ! WARNING! Never use a machine that has faulty safety equipment! Carry out the inspection, maintenance and service routines listed in this section. ! WARNING! Never use a cutting attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is fitted this can cause serious personal injury.
English – 5 SAFETY INSTRUCTIONS Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. The machine ′ s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine ′ s handle unit. 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. 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. Cutting equipment A trimmer head is intended for trimming grass. Locking nut A locking nut is used to secure some types of cutting attachment. ! 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. ! 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 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!
6 – English SAFETY INSTRUCTIONS Checking, maintaining and servicing the machine ′′′ ′ s safety equipment Throttle lock • 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. • 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. Stop switch • Start the engine and make sure the engine stops when you move the stop switch to the stop setting. Cutting attachment guard • Ensure that the guard is undamaged and is 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 chapter on Technical data. Vibration damping system • Regularly check the vibration damping units for cracks or deformation. • Check that the vibration damping element is undamaged and securely attached. Muffler • Never use a machine that has a faulty muffler. • Regularly check that the muffler is securely attached to the machine. 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.
English – 7 SAFETY INSTRUCTIONS • If the muffler on your machine is fitted with a spark arrestor mesh then it should be cleaned regularly. A blocked mesh causes the engine to overheat, which can lead to serious damage. Never use a muffler with a defective spark arrestor mesh. Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: • Obtain maximum cutting performance. • Extend the life of cutting equipment. General rules 1 Only use cutting attachments with the guards we recommend! See the chapter on Technical data. 2 Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced. Locking nut • 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. 35-50 Nm (3.5- 5 kpm). CAUTION! The nylon lining inside the locking nut must 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 Trimmer head • Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data. • Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared. • The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter. • Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length. • To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer. ! 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: Reduce the risk of blade thrust. Obtain maximum cutting performance. Extend the life of cutting equipment. Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter. IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. ! 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.
8 – English SAFETY INSTRUCTIONS General safety precautions Starting • The complete clutch cover and shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury. • Never start the machine indoors.

When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately.
English – 9 SAFETY INSTRUCTIONS • The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage. General working instructions Basic safety rules 1 Look around you: • To ensure that people, animals or other things cannot affect your control of the machine. • To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment. • CAUTION! Do not use the machine unless you are able to call for help in the event of an accident. 2 Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. 3 Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground. 4 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. 5 Never put the machine down with the engine running unless you have it in clear sight. Basic working techniques • Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage. Grass trimming using a trimmer head and plastic blades Trimming • Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut. • The cord can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts. • Reduce the risk of damaging plants by shortening the cord to 10-12 cm and reducing the engine speed. Clearing • The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord. • The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences. • When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head. ! WARNING! Take care when handling fuel. Bear in mind the risk of fire, explosion and inhaling fumes. IMPORTANT! This section describes the basic safety precautions for working with clearing saws and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability. You must understand the difference between forestry clearing, grass clearing and grass trimming before use. ! WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.
10 – English SAFETY INSTRUCTIONS Cutting • The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool. • Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head. Sweeping • The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro. • When cutting and sweeping you should use full throttle to obtain the best results. ! WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the blade is rotating, as this can result in serious injury. Stop the engine and blade before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burnt if you touch it. ! WARNING! Watch out for thrown objects. Always wear eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches.
