Hey all,
I’m a noob at air tools, and I recently decided to get my feet wet.
I decided to start with a 20 gallon air compressor: http://www.princessauto.com/en/detail/20-gallon-portable-air-compressor/A-p8474983e
And an Impact Wrench with a max torque of 230ft-lbs: http://www.princessauto.com/en/detail/1-2-in-dr-air-impact-wrench/A-p8571663eHere’s the problem, no matter how high I set the PSI, I can’t seem to loosen the lug bolt on my car that’s torqued to 87ft-lbs
Am I doing something wrong?
In the manual it says to fill the drill with oil via the air inlet, and to run it till it clears all the oil out of the exhaust vents the first time.
I did that, yet it still seems to have no power.Any ideas?
Total air tools noob here, so please let me know if I’m missing something obvious.
Thanks,
Nabeel

That impact gun is awful the torque figure listed is the max torque not the working torque so probably looking at around 120-180 working torque with that being said have you removed the wheels with a bar and then torqued them or are you trying to remove them for the first time without knowing if they’ve been torqued? chances are the bolts have been overtightened when they where put on and the gun simply isn’t powerful enough to remove them.
I was the one who installed the wheels last, and I torqued them to 87ft-lbs, so unless they have tightened by themselves, which I don’t think is possible, then they should still be at 87ft-lbs.
When at the selected pressure at the regulator, what is the pressure at the coupling (hose end)? Also, is it turning in the proper direction, impact guns have a switch to select in which direction they turn.
