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 in the USA or EN 166 in EU countries. Visors must comply with standard EN 1731. 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 jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level. 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 ”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! Whenever you use a clearing 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 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.

Tools ___________________________________ 51 2 1 502 51 03-01 General recommendations Bear in mind: Do not start the engine without the clutch drum and driveline fitted as the clutch can become detached and cause severe personal injury. Do not touch hot components, e.g. the muffler and clutch before they have cooled sufficiently to avoid burns. Avoid getting fuel or oil on your skin or in your mouth. Use a barrier cream on your hands. This reduces the risk of infection and makes dirt easier to wash away. Long term contact with engine oil can represent a health hazard. Never start the engine indoors. Exhaust fumes are poisonous! Wipe up oil spills from the floor immediately to avoid slipping. Do not use tools that are worn or fit badly, for example on nuts and bolts. + Always work on a clean bench. + Always work logically to ensure all parts are fitted correctly and that nuts and bolts are tightened. + Use the special tools where recommended to be able to carry out the work correctly and efficiently. Special tools Some of the work described in the Workshop Manual requires special tools. In each section where this is necessary there is a picture of the tool and an order number. We recommend the use of special tools in order to avoid expensive damage to parts in question and personal injury and to provide an efficient repair procedure. Contact faces and gaskets Ensure all surfaces are clean and free from gasket residue, etc. When cleaning use a tool that will not damage the contact face. Any scratches or unevenness should be removed using a flat fine cut file. Sealing rings Always replace a sealing ring that has been dismantled. The sensitive sealing lip can easily be damaged resulting in inferior sealing capacity. Surfaces which the seal shall seal against must also be completely undamaged. Lubricate the sealing lip with grease before it is fitted and ensure that it is not damaged e.g. by shoulders and splines on a shaft. Use tape or a conical sleeve as protection. It is important that the sealing ring faces in the right direction for it to act as it is intended. The workshop used to carry out repairs must be equipped with safety devices in accordance with local directives. No one may carry out repairs without first having read and understood the contents of this Workshop Manual. The boxes below can be found in appropriate parts of this manual. WARNING! The warning box warns of the risk for personal injury if the instructions are not followed. NOTE! This box warns of damage to material if the instructions are not followed. The machine is type approved for safety in accordance with applicable legislative demands with the equipment specified in the Operator’s Manual. The assembly of other equipment or accessories or spare parts not approved by Husqvarna can result in the failure to meet these safety demands and that the person carrying out assembly bears responsibility for this. Poisonous fumes When using cleaning agents read the instructions carefully. Ensure there is good ventilation when handling petrol and other volatile fluids. The engine's exhaust fumes are poisonous. Test run the engine outdoors. Fire risk Handle fuel with respect as it is extremely inflammable. Do not smoke and ensure there are no open flames or sparks in the vicinity. Make sure there is a working fire extinguisher close at hand. Do not try to extinguish a petrol fire with water. 3 1 1 Starter Contents Dismantling ___________________________________ 4 Assembly ____________________________________ 4 Replacing the drive dogs ________________________ 6
