This is best done with a wire brush. A blocked screen will cause the engine to overheat and may lead to serious damage. Note! The screen must be replaced if it is damaged. If the screen is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a muffler that is in poor condition. Never use a muffler if the spark arrestor screen is missing or defective. The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material. A muffler equipped with a catalytic converter significantly reduces the amount of hydrocarbons (HC), nitrogen oxides (NO) and aldehydes in the exhaust fumes. Carbon monoxide (CO), which is poisonous and odorless, is not however reduced! Consequently, never work in an enclosed or badly ventilated area. Good air circulation should always prevail when working in snowy hollows, ravines or in confined conditions. Starter Changing a broken or worn starter cord • Loosen the screws that hold the starter against the crankcase and remove the starter. • Pull out the cord approx. 30 cm (12 inches) and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards. • Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley. Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the center of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord. ! 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. Care must be exercised when replacing the return spring or the starter cord. Wear protective glasses and protective gloves. English – 33 MAINTENANCE Tensioning the recoil spring • Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. Note! Check that the pulley can be turned an additional 1/ 2 turn when the starter cord is pulled all the way out. Changing a broken recoil spring • Lift up the starter pulley. See instructions under the heading Changing a broken or worn starter cord. Remember that the recoil spring is coiled under tension in the starter housing. • Remove the cassette with the recoil spring from the starter. • Lubricate the recoil spring with light oil. Fit the cassette with recoil spring in the starter. Fit the starter pulley and tension the recoil spring. 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. • Fit and tighten the screws that hold the starter. Air filter The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts • Excessive fuel consumption. • Remove the air filter after taking off the air filter cover. When refitting make sure that the air filter seals tightly against the filter holder. Clean the filter by brushing or shaking it. The filter can be cleaned more thoroughly by washing it in water and detergent. An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced. A JONSERED chain saw can be equipped with different types of air filter according to working conditions, weather, season, etc. Contact your dealer for advice. MAINTENANCE Spark plug The spark plug condition is influenced by: • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). Note! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is fitted with a suppressor. Lubricating the bar tip sprocket • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0.5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.

The engine must be stopped when making adjustments. –+ 12 3 Lubricate the bar tip sprocket each time you refuel. Use the spe...
