Replacing the spark plug on your Hitachi gas line trimmer

  • Wear work gloves to protect your hands and work in a well-ventilated area.
  • Disconnect the spark plug wire from the spark plug.
  • Using a spark plug wrench, unthread and remove the spark plug from the engine cylinder. Don't let debris fall into the cylinder while you have the spark plug removed.
  • Using a spark plug gap tool, set the spark plug gap according to the specification provided in your owner's manual for the line trimmer.
  • Carefully thread the spark plug into the engine and tighten the spark plug firmly using the spark plug wrench.
  • Connect the spark plug wire to the spark plug.

Top replacement parts for Hitachi gas line trimmers

  • Carburetor. The carburetor mixes air with fuel in the proper proportion to produce a combustible gas. That gas/air mixture then moves into the cylinder where it is compressed by the piston and ignited by the spark plug.
  • Fuel filter. The fuel filter attaches to the end of the fuel line inside the gas tank. It filters particles from the gasoline as it moves from the fuel tank to the carburetor.
  • Ignition module. The ignition module supplies spark voltage to the spark plug on the engine.
  • Spark plug. The spark plug produces the spark that ignites the fuel in the engine.
