MAINTENANCE WARNING: Mufflers fitted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! WARNING: The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler. WARNING: Bear in mind that: Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated. The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! Spark plug Two--piece shaft 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) will seize if they are not lubricated regularly. Air filter 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 The spark plug condition is influenced by: S Incorrect carburetor adjustment. S An incorrect fuel mixture (too much or in- correct type of oil). S 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 0,6 mm. The spark plug should be replaced after about a month in operation or earlier if necessary. 0,6 mm 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. CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. 115299326 Rev. 2 7/15/10 English--- 18
