Air filter MAINTENANCE Sharpening grass cutters and grass blades The air filter must be regularly cleaned to remove dust and dirt in order to avoid: S Carburetor malfunctions S Starting problems S Loss of engine power S Unnecessary wear to engine parts S Excessive fuel consumption Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty. Cleaning the air filter Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Rinse thoroughly. Ensure that the filter is dry before refitting it. 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. Bevel gear WARNING: Always stop the en- gine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it. S See the cutting attachment packaging for correct sharpening instructions. S Sharpen blades and cutters using a single--cut flat file. S Sharpen all edges equally to maintain the balance of the blade. WARNING: Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type. The bevel gear is filled with the right quan- tity 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. 577387001 Rev. 2 1/6/11 English--- 22
