English – 21 MAINTENANCE Starter Checking the starter cord •Loosen the screws that hold the starter against the crankcase and remove the starter. • Pull the cord out about 30 cm and lift it into the cut-out in the periphery of the starter pulley. When the cord is intact: Release the spring tension by letting the pulley rotate slowly backwards. Changing a broken or worn starter cord •Remove any remnants of the old starter cord and check that the return spring works. Insert the new starter cord through the hole in the starter housing and in the cord pulley. • Secure the starter cord around the cord pulley as illustrated. Tighten the fastening well and ensure that the free end is as short as possible. Secure the end of the starter cord in the starter handle. Tensioning the recoil spring •Guide the cord through the cut-out in the periphery of the pulley and wind the cord 3 times clockwise around the centre of the starter pulley. • Now pull the starter handle and in doing so tension the spring. Repeat the procedure once more, but this time with four turns. • Note that the starter handle is drawn to its correct home position after tensioning the spring. • Check that the spring is not drawn to its end position by pulling out the starter line fully. Slow the starter pulley with your thumb and check that you can turn the pulley at least a further half turn. Changing a broken recoil spring •Undo the bolt in the centre of the pulley and remove the pulley. • Bear in mind that the return spring lies tensioned in the starter housing. • Loosen the bolts holding the spring cassette. • Remove the recoil spring by turning the starter over and loosen the hooks, with the help of a screwdriver. The hooks hold the return spring assembly on the starter. • Lubricate the recoil spring with light oil. Fit the pulley and tension the recoil spring. ! WARNING! When the recoil spring is wound up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury. Always be careful when changing the recoil spring or the starter cord. Always wear protective goggles.
22 – English MAINTENANCE Fitting the starter •To fit the starter, first pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls. • Tighten the screws. Fuel system General •Check that the fuel cap and its seal are not damaged. • Check the fuel hose. Replace when damaged. Fuel filter •The fuel filter sits inside the fuel tank. • The fuel tank must be protected from contamination when filling. This reduces the risk of operating disturbances caused by blockage of the fuel filter located inside the tank. • The filter cannot be cleaned but must be replaced with a new filter when it is clogged. The filter should be changed at least once per year. Air filter The air filter only needs to be checked if the engine drops in power. • Loosen the screws. Remove the air filter cover. • Check the air filter and replace if necessary. Replacing the air filter •Remove the screw. • Replace the air filter. Drive gear, clutch •Check the clutch centre, drive gear and clutch spring for wear. NOTICE! The air filter must not be cleaned or blown clean with compressed air. This will damage the filter.
