WARNING
•Make sure that the engine has stopped and is cool before performing any service to the machine. Con- tact with moving cutting head or hot muffler may result in a personal injury.
AIR FILTER
•The air filter, if clogged, will reduce the engine perfor- mance. Check and clean the filter element in warm, soapy water as required. Dry completely before in- stalling. If the element is broken or shrunk, replace with a new one.
FUEL FILTER
•When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.
