Cleaning the air filter Soiled air filters reduce the engine power by supplying too little air to the carburettor. Regular checks are therefore essential.

  • Page 25: Storage

    WARNING! Never run the engine without the air filter element installed. Worn parts Even when used in the intended way, some components are subject to normal wear. These will have to be replaced depending on the kind of duration and usage. These parts include, among others, the cutting tool and the retaining disk.
  • Page 26 Storing the equipment If you intend to store the equipment for longer than 30 days, the equipment must be prepared accordingly; otherwise the fuel still remaining in the carburettor will evaporate and leave a rubbery sediment. This can cause problems when starting up the equipment and may require expensive repairs.
  • Page 27 If the cutting device runs idle, correct the idle speed. Allow the engine to warm for 3-5 minutes (No high speeds!). 2. Turn the adjusting screw (S): clockwise - idle speed increases (+) counterclockwise - Idle speed decreases (-) The idle speed is 3000 min Contact the manufacturer if the cutter continues to run at idle.
