Instruction:
1.Run the engine to the normal operating temperature. Stop the engine, unload spark plug wires. Clean all spark plug wells if necessary.
2.Remove the spark plugs and the air filter, set the throttle wide open position. Disconnect the ignition system. Press the compression tester push-on connector, or connect the right thread adapter to the hose and screw it into the spark plug hole(Hand tighten only, DO NOT tighten too much with a wrench). Connect the coupling on the gauge to the push-on connector or the hose. Make sure all connections are fully engaged.
3.Crank the engine for at least 5 compression strokes. Wait for the pressure reading on the gauge stops at a certain value. Record the compression reading and then press the button（release valve）to relieve the pressure.
4.Repeat the above procedures, each cylinder measures 2 to 3 times to ensure the measurement accuracy. The removed components should be put back in place after the operation, especially before engine running.
5.Note to return the throttle plates to the closed position and reconnect the ignition system wiring.
Safety Tips:
1.Do not use equipment if damaged.
2.Wear eye protection. Do not wear jewellery and tie back long hair.
3.Tidy up all used tools and equipment and never leave them in, on or near engine.
4.When not in use, place in protective case and store in a safe, dry and childproof place.
5.Ensure that the adaptor is securely fastened to the hose to prevent possible separation when the adaptor is removed from the cylinder head.
Wide Application:
The engine cylinder compression test tool kit can be widely used for most type and depth spark plug well. If you have motorcycle car truck ATV mower and any other vehicles with gasoline or gas engine, and you are a professional on repairing vehicles, you can try this kit. Please note, this cylinder compression test gauge is not suitable for most diesel engine, because the range of the gauge is only 0-300PSI, which is much lower than most diesel engine compression.
