3. Put the throttle and choke into the fully open position.
4. Press the tapered rubber joint of the cylinder pressure gauge into the spark plug bore of the test cylinder (or screw the threaded pipe connection onto the spark plug bore).
5. Use the starter to drive the crankshaft to rotate 3-5S (not less than four compression strokes), take the reading after the pointer is stable, and then press the unidirectional button to reset the pointer to zero.
6. Repeat step 5, it should be noted that the number of measurements of each cylinder should not be less than twice and the measurement results should be taken as the average of its measurement times.
