4 – English The machine‘s safety equipment This section describes the machine‘s safety equipment, 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.) Personal protective equipment SAFETY INSTRUCTIONS ! WARNING! Never use a machine with defective safety equipment. Follow the control, maintenance and service instructions described in this section. 1. Throttle trigger lock The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (A) is pressed into the handle (= when you hold the handle) the throttle (B) is released. 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 independent return spring systems. This means that the throttle is automatically locked in its “idling“ position. 2. Stop switch The stop switch should be used to stop the engine. 3. Cutting attachment guard This guard is intended to prevent objects from being thrown towards the operator and to protect the operator from unintentionel contact with the cutting attachment. WARNING! Under no circumstances may the cutting equipment be used without an approved guard fitted. See the chapter “Technical data” . If the wrong guard or a defective guard is fitted this can cause serious personal injury. ! MPORTANT INFORMATION •A clearing saw, brushcutter or trimmer used incorrectly or carelessly can become a dangerous tool, that can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the content of this manual. •When using a trimmer, personal 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. GLOVES Gloves should be worn when necessary, e.g., when assembling cutting equipment. EAR PROTECTION Ear protection offering sufficient dampening effect should be used. EYE PROTECTION Blows from branches or objects thrown by the rotating cutting equipment 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, long pants. Do not wear jewelry, short pants, 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. A B A B " ! WARNING!

English – 5 SAFETY INSTRUCTIONS 4. Vibration damping system Your machine is equipped with a vibration damping system, which is designed to give as vibration-free and comfortable use as possible. Use of incorrectly wound cord or incorrect cutting equipment increases the level of vibration. The machine’s vibration damping system reduces the transfer of vibrations between the engine unit/ cutting equipment and the machine’s handle unit. 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 converter 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. 6. Cutting equipment The trimmer head is intended for trimming grass. 7. Locking nut A locking nut is used to secure some types of cutting equipment on the output shaft. ! 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.
6 – English 3. Cutting attachment guard •Ensure that the spray guard is undamaged and is not cracked. •Replace the guard if it has been exposed to impact or is cracked. •Always use the prescribed blade an guard combination, see chapter Technical data. SAFETY INSTRUCTIONS Control, maintenance and service of the machine‘s safety equipment 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 the 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.

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 section Start. Start the machine and apply full throttle. Release the throttle and check that the cutting equipment stops and remains at a standstill. If the cutting equipment rotates with the throttle in the idling position then the carburettor‘s idling setting must be checked. See chapter “Maintenance“. 2. Stop switch •Start the engine and make sure that the engine stops when the stop switch is moved to the stop position. 4. Vibration damping system •Check the vibration damping element regularly for material cracks and distortion. •Check that the vibration damping element is undamaged and securely attached. # 5. Muffler 1. Never use a machine that has a defective muffler. 2. Check regularly that the muffler is secure. 3. 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.
English – 7 SAFETY INSTRUCTIONS 6. Cutting equipment The section describes how through correct maintenance and through using the right type of cutting equipment you can: •Obtain maximum clearing capacity. •Increase the service life of the cutting equipment. Two basic rules: 1)Only use the cutting and guard equipment we recommend! See chapter “Technical data“. 2)Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced. Cutting equipment 7. Locking nut •Protect your hand from injury when assembling, use the blade guard as protection when tightening with a socket spanner. Tighten the nut by turning against the direction of rotation. Loosen the nut by turning in the direction of rotation. (NOTE! the nut has a left-hand thread). •Tighten the nut using a socket spanner, 35 - 50 Nm (3.5 - 5 kpm). Trimmer head •Only use a trimmer head and trimmer cord that is recommended. 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 cutting equipment we recommend! See chapter “Technical data“. NOTE! The locking nut‘s nylon lock must not be so worn that it can be turned by hand. The lock shall hold at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.•Generally smaller machines require a small trimmer head and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and also meet resistance from 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 the knife positioned 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 few days. This will make the line tougher and it will keep longer. 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. IMPORTANT INFORMATION The section describes how through correct maintenance and through using the right type of cutting equipment you can obtain maximum clearing capacity and increase the service life of the cutting equipment. •Only use the cutting and guard equipment we recommend! See chapter “Technical data“. IMPORTANT INFORMATION Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise harmful vibrations will occur.

English – 9 ! General working instructions SAFETY INSTRUCTIONS Basic working techniques •Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine (that is without resistance, which the engine feels from the cutting equipment when trimming) can lead to serious engine damage. Basic safety precautions 1. Observe your surroundings: •To ensure that people, animals or other things cannot affect your control of the machine. •To ensure that the above mentioned do not come into contact with the cutting equipment or objects that can be thrown by the cutting equipment. •NOTE! Never use a machine without the possibility of calling for help in the event of an accident. WARNING! Sometimes branches, grass or wood can get caught between the guard and cutting equipment. Always stop the engine when cleaning. 2. Avoid usage in unfavourable weather conditions. For example, thick fog, heavy rain, strong winds or extreme cold, etc. To work in bad weather conditions is tiring and can create dangerous circumstances, e.g. slippery surfaces. 3. Make sure you can walk and stand safely. Look out for any obstacles with unexpected movement (roots, stones, branches, pits, ditches, etc.). Take great care when working on sloping ground. 4. The engine should be switched off before moving. When moving over longer distances and transporting the transport guard should be used. 5. Never put the machine down with the engine running unless you have good sight of it. 6. Do not over-reach 7. Keep Cutting attachment below waist level. IMPORTANT INFORMATION •This section takes up the basic safety precautions for working with the trimmer. •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. Grass trimming using the trimmer head and plastic knifes •Hold the trimmer head just above the ground at an angle. It is the end of the cord that carries out the work. Let the cord work at its own pace. Do not 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.
10 – English SAFETY INSTRUCTIONS 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. NOTE! 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.Trimming •The trimmer is ideal to cut 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 procedures. Constant contact can cause damage and wear to the trimmer head. Sweeping •The rotating cord‘s fanning effect can be used for quick and easy cleaning. Hold the cord parallel to and above the area to be swept and move the trimmer from side to side. •When cutting and sweeping you should use full throttle to obtain the best results. ! WARNING! Warning for thrown objects. Always wear protective glasses. Never lean over the 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 (50 feet). Stop the machine immediately if anyone approaches. ! WARNING! The bevel gear unit can get hot during use and may remain so for a while afterwards. There is a risk of slight burns if you touch it.
