Wash itclean in warm, soapy water. Ensure that the filter is dry beforerefitting it.An air filter that has been in use for a long time cannot becleaned completely. The filter must therefore be replaced witha new one at regular intervals. A damaged air filter mustalways be replaced.If the machine is used in dusty conditions the air filter shouldbe soaked in oil. See instructions under the heading Oiling theair filter.Oiling the air filterAlways use special filter oil. Filter oil contains a solvent tomake it spread evenly through the filter.

Squeeze theexcess oil out of the filter inside the plastic bag and pour offthe excess before fitting the filter to the machine. Never usecommon engine oil. This would drain through the filter quitequickly and collect in the bottom.Spark plugThe spark plug condition is influenced by:• Incorrect carburetor adjustment.• An incorrect fuel mixture (too much or incorrect type ofoil).• A dirty air filter.These factors cause deposits on the spark plug electrodes,which may result in operating problems and startingdifficulties.If the machine is low on power, difficult to start or runs poorlyat idle speed: always check the spark plug first before takingany further action. If the spark plug is dirty, clean it and checkthat the electrode gap is 0.5 mm (0,020"). The spark plugshould be replaced after about a month in operation or earlierif necessary.CAUTION!
