Setup and Assembly

1. Fueling the Engine

This jack hammer uses a gasoline engine. It is crucial to use the correct fuel mixture as specified by the manufacturer (typically a gasoline/oil mix for 2-stroke engines, though this model is 4-stroke, so separate oil and gas tanks). Refer to the engine's specific requirements for fuel type and oil.

  • Ensure the engine is off and cool before refueling.
  • Locate the fuel tank cap and oil fill cap.
  • Carefully pour fresh, clean gasoline into the fuel tank using the provided funnel. Do not overfill.
  • Fill the engine oil reservoir with the recommended engine oil (check engine manual for type and capacity).
  • Securely replace both caps.

  • Select the appropriate chisel bit (bull point or flat) for your task.
  • Ensure the bit receiver is clean and free of debris.
  • Insert the shank of the chisel bit into the tool holder until it clicks into place.
  • Pull on the bit to ensure it is securely locked.
