need pressure
by: Joe

I was using my Kobalt 20 gal compressor to blow out my lawn irrigation zones compressor worked ok for first 3 zones but now the compressor will not go past 25 PSI and it keeps running. Why?

Kobalt compressor w/build pressure
by: Anonymous

I had the same issue and it was the extension cord. I was using a 100' cord and the unit would build pressure to about 50psi and then start bogging down and shut off. I went back to my electrical training and remembered high amperage draw units are finicky when it comes to the resistance in long cable runs (100' extension cords). I plugged it directly into the outlet and no issues since. If you must use an extension cord, use the shortest possible
