⚠️ Important Usage Notes

 

1. Thread the spark plug into the tool base until fully seated, then slide the desired feeler gauge blade between the center and ground electrode before tightening the adjustment screw down to your target gap distance.

2. Do not over-tighten the adjustment knob beyond contact with the feeler gauge blade to avoid bending the ground electrode out of parallel or damaging fragile iridium/platinum tips.
