Compressor won't power impact wrench or rachet
Hey everyone. I own a Kobalt 30 gallon compressor with the following specs:
2 cylinder
1.6 running hp
155 max psi
5.3 scfm 90 psi
6.2 scfm 40 psi
It seems to be working fine for most of my tools, but has never been able to power my ingersoll rand impact wrench (1/2", 90 psig) or rachet. In fact, it won't turn them at all. I recently took the tools to a local tire shop and asked them to plug them into their air hose to verify they work, and they both work perfectly. Also, I am using a 1/2", 100' hose.
Do you guys have any ideas why this isn't working or things I can do to make them work?

It is possible that your air line is connected to an outlet on the compressor that is controlled by a regulator.
The regulator may be turned to a low pressure.
Also, the regulator could also be turned to its highest setting but is defective and won't let enough air pass.
A way to check this would be to have an air gauge at the impact end of the hose to see if the pressure drops to near zero when the tool is activated.

I note in the specs you gave, nowhere did it state the tank size in gallons. I'm curious. Too small a tank will not give the volume to run air tools. It does sound like a 40 gallon, however.
What does your outlet gauge read when the line is "dead ended" with a blower? Sometimes outlet regulators go south and pinch off the air. Fine for impulse use, such as a nail driver, but constant air won't get'r done.

Larry, he said it was a Kobalt 30 gallon.
I wonder if the 100' of 1/2" air hose is a contributing factor although I agree with mgmine that even with insufficient air, the tool ought to try and run a little.

Sheesh, went right in one eye and out my ear, I guess. I was going to mention the 1/2" hose, but I believe it should turn a little even with the larger hose.
Nick, remove the pressure from the tank, and remove the regulator. Hook your hose directly up to the outlet, then power it up. The air tool won't be affected by a little full pressure. If it works, then you know you have a bad regulator, which I suspect.
