Champion Sprinkler Valve Manual

This covers the following Champion Power Equipment models: All standard open-frame generators, including open-frame inverters, and stand alone engines.

Read instructions carefully and completely before performing service.
  • To reduce the risk of injury, user must read and understand the operator’s manual before using this product.
  • DO NOT make any adjustments to the generator without first stopping the engine and disconnecting the spark plug wire.
  • Burns from hot parts — let the engine cool completely before touching hot parts.
  • Injury from moving parts
  • To reduce the possibility of fire or explosion, be careful when working around gasoline. Keep cigarettes, sparks and flames away from all fuel‐related parts.
The valve adjustment on these engines will extend the useful life by keeping the clearance between the rocker arm and valve stem at the correct measurement. Too loose of a clearance and the chance of valve collar failure increases along with excessive noise from the rocker arm hitting the end of the valve stem like a hammer. Too tight a clearance and hard starting or significant loss of compression will take power away from the engine.

Please perform this procedure when the engine is cold.

  • Use a valve box (not included) to protect the sprinkler valve system 3. Once a location is selected, dig a hole in the ground deep enough so the top of the valve box will be flat and level with the surface.
