To avoid serious personal injury, always stop the engine
and allow it to cool before cleaning or maintaining the
unit. Never perform cleaning or maintenance while
the unit is running. Disconnect the spark plug wire to
prevent the unit from starting accidentally..
Old engine oil is considered special waste and has
to be disposed according to your local environment
protection regulation. Do not pour the oil into a garbage
