Instructions for using a feeler gauge
(1) Wipe the measuring surface of the feeler gauge clean with a clean cloth. Do not measure the gauge with oil stains or metal shavings on it, otherwise it will affect the accuracy of the measurement results.
(2) Insert the feeler gauge into the measured gap, pull the gauge back and forth, and feel a slight resistance, indicating that the gap value is close to the value marked on the gauge; If the resistance is too high or too low when pulling, it indicates that the gap value is less than or greater than the value marked on the gauge.
(3) When measuring and adjusting the gap, first select a feeler gauge that meets the gap regulations and insert it into the measured gap. Then adjust while pulling the feeler gauge until you feel a slight resistance and tighten the locking nut. At this point, the value marked on the feeler gauge is the measured gap value.
