FUEL HANDLING Fuel safety Petrol Never start the machine: 1. If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2. If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water. 3. If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines. CAUTION! Always use a good quality petrol/oil mixture (at least 90 octane).
FUEL HANDLING Mixing S Always mix the petrol and oil in a clean container intended for fuel. S Always start by flling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol. S Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank. S Do not mix more than one month’s supply of fuel at a time. S If the machine is not used for some time, the fuel tank should be emptied and cleaned.
STARTING AND STOPPING Check before starting WARNING: When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately. S Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. S Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. S Place the machine on the ground, ensure the cutting attachment is clear of twigs and stones.
STARTING AND STOPPING Stopping Stop the engine by pushing and holding the stop switch in the STOP position until the engine stops.

WORKING TECHNIQUES General working instructions IMPORTANT! This section describes the basic safety precautions for working with trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your servicing dealer. 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. Basic safety rules 1.
WORKING TECHNIQUES S Reduce the risk of damaging plants by shortening the trimmer line to 4--4 1/2 inches (10--12 cm) and reducing the engine speed. S When trimming you should use less than full throttle so that the trimmer line lasts longer and to reduce the wear on the trimmer head. Clearing Sweeping S The fan effect of the rotating line can be used for quick and easy clearing up. Hold the trimmer line parallel to and above the area to be swept and move the tool to and fro.
MAINTENANCE The owner is responsible for the performance of all required maintenance as defined in the operator’s manual. Idle Speed Screw--T Carburetor Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8--10 tanks of fuel, the engine will be run--in. To ensure that it continues to run at peak performance and to minimize harmful exhaust emissions after the run--in period, ask your servicing dealer to adjust your carburetor.
MAINTENANCE WARNING: Two--piece shaft WARNING: The drive shaft end in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive shaft ends (splined coupling) will seize if they are not lubricated regularly. 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.
MAINTENANCE Bevel gear The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three--quarters full with grease. Use HUSQVARNA special grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out. 115299326 Rev.
