Always make sure nylon string head or blade have been assembled correctly (see sections NYLON STRING HEAD and BLADE ASSEMBLY) and blade fastener is tightened. 1) AIR FILTER CLEANING (at least every 25 working hours). A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum speed and cause high fuel consumption and/or difficult starting. Remove filter cover as shown in figure 1. Carefully clean the inside of filter box. The filter can also be cleaned with compressed air. 2) Every 50 working hours inject the gearcase with gear grease under high pressure through hole (C). 3) SPARK PLUG From time to time (at least every 50 hours) remove and clean the spark plug and check N.
