Resumen del manual
Never use a harness with a defective quick release catch. Quick release On the front is an easily accessible, quick release catch: • Pull out the red strap. • The hip strap and one shoulder strap will be automatically released at the same time and the harness and the engine unit will slide to the ground. Use this if the engine should catch fire or in any other emergency situation when you quickly need to take off the harness and machine. Equal load on shoulders A well matched saw and harness make work much easier. Adjust the harness to give the best working stance. Adjust the side straps so that the weight is equally divided across the shoulders. 16 – English FUEL HANDLING Fuel NOTE! The machine is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel. !WARNING! Always provide good ventilation when handling fuel. Petrol NOTE! Always use an oil-mixed quality petrol (at least 90 octane). If your machine is equipped with a catalytic converter, (see “technical data”) an unleaded, oil mixed quality petrol should always be used. A leaded petrol will destroy the catalytic converter. • The lowest recommended octane rating is 90. If you run the engine on a petrol with a lower octane rating than 90 so-called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown. • When working at continuous high revs a higher octane rating is recommended. Two-stroke oil • For the best results use Husqvarna two-stroke oil, which has been specially produced for brush cutters and chain saws. Mixing ratio 1:50 (2%). • If Husqvarna two-stroke oil is not available you can use a high quality two-stroke oil intended for air cooled engines. Contact your dealer when selecting an oil. Mixing ratio: 1:25 (4%). • Never use two-stroke oil intended for water cooled outboard motors, so-called outboard motor oil. • Never use oil intended of four-stroke engines. Mixture • Always mix petrol and oil in a clean container intended for petrol. • Always start by filling half the quantity of petrol required. Then add the entire oil quantity. Mix (shake) the fuel mixture. Fill the remaining quantity of petrol. • Mix (shake) the fuel mixture carefully before filling in the machine‘s fuel tank. • Do not mix more than max. one month’s supply of fuel. • If the brush cutter is not used for a long period of time, the fuel tank should be emptied and cleaned. Fuelling ! ! WARNING! The following precautions reduce the risk of fire: Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running. Always stop the engine and let it cool for a few minutes before refuelling. Open the fuel cap slowly when fuelling so that any over pressure is released slowly. Tighten the fuel cap carefully after refuelling. Always move the machine from the fuelling place before starting. • Clean around the fuel cap. Contamination in the tank can disrupt operations. • Ensure that the fuel is well mixed by shaking the container before filling the tank. • Always use a fuel container with an anti- spill valve.

The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found. • Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked. • Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm. • Check that the guard is not damaged or cracked. Replace the guard if it is exposed to impact or is cracked. • Check that the trimmer head and spray guard are not damaged or cracked. Replace the trimmer head or spray guard if they are exposed to impact or are cracked. • Never use the machine without a guard or spray guard nor with a defective guard. Start and stop ! ! WARNING! The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury. Always move the machine from the filling area before starting. Place the machine on a flat surface. Ensure the cutting equipment cannot come into contact with any object. Make sure no unauthorised persons are in the working area, otherwise t...
