3. Tighten the screws that hold the starter. 1. If the product is not easy to start or to operate or if the product operates incorrectly at idle speed, examine the spark plug for unwanted materials. To decrease the risk of unwanted material on the spark plug electrodes, do these steps: a) make sure that the fuel mixture is correct. b) make sure that the air filter is clean. 2. Clean the spark plug if it is dirty. 3. Make sure that the electrode gap is 0,5 mm/0.020 in. To clean the air filter Clean the air filter regularly from dirt and dust. This prevents carburetor malfunctions, starting problems, loss of engine power, wear to engine parts and more fuel consumption than usual. 1. Remove the cylinder cover and the air filter. 2. Use a brush or shake the air filter clean. Use detergent and water to clean it fully. Note: An air filter that is used for a long time can not be fully cleaned. Replace the air filter regularly and always replace a defective air filter. 3. Attach the air filter and make sure that the air filter seals tightly against the filter holder. 4. Replace the spark plug monthly or more frequently if necessary. To sharpen the saw chain Information about the guide bar and saw chain WARNING: Use protective gloves when you use or do maintenance on the saw chain. A saw chain that does not move can also cause injuries. Replace a worn or damaged guide bar or saw chain with the guide bar and saw chain combination recommended by Husqvarna. This is necessary to keep the safety functions of the product. Refer to Accessories on page 34, for a list of replacement bar and chain combinations that we recommend. • Guide bar length, in/cm.
