Husqvarna 525RX Operation Manual - Page 27

Air filter MAINTENANCE Bevel gear 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. 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. Two-piece shaft (525RK) Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty. Cleaning the air filter Close the choke control by setting the choke into a choke position. 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) on models with two-piece shafts will seize if they are not lubricated regularly. Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Clean also the inside of the filter cover by using air or a brush. Ensure that the filter is dry before refitting it. Remove the Felt filter from the filter holder and gently brush debris from the filter. Check the rubber sealing surface. Change the filter on the rubber seal if damaged. 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. Damaged, very dirty, or fuelsoaked air filter must always be replaced. English - 27
