What to do when the pressure-regulating valve is not working?
Ans :
A compressor with excessive grease build-up may prevent the parts in the pressure-regulating valve from working smoothly. When it goes worn out by oxidation, turn the pressure-regulating valve counterclockwise and remove the plastic parts inside before removing the greasy stain with tools and eventually clean the kit using spray gun oil. After cleaning, load the parts back accordingly to resume normal operation.
