Make sure that you have at least 50 psig of air pressure before you attempt to troubleshoot your impact. 70 is better, 90 is perfect. Impact wrenches are powered by internal sliding vanes, which can sometimes stick. There are a couple of ways to get it going again. Try 1 before going to 2, etc,:
1. Spray W-D 40 or a similar oil into the impact, while you are holding the trigger down. Give it a good shot. Connect the hose and pull the trigger. Tap the sides of the gun with a plastic hammer to help free up the vanes. Repeat. Normally, this is enough to get you back running.
2. Place it in a bucket and cover the gun with W-D 40. Work the anvil end and trigger to work the oil deep into the gun. Ley it soak 1 hour, and repeat the process, working the oil in, and the air out. Remove it from the oil, and drain the oil back into the bucket by holding the trigger down. Hook up the air, and blow it out.
3. Remove the cover on the head that covers the vanes. Make sure that the vanes will slide freely, and that all gaskets and "O" rings are in good condition. If you note any dry areas in the inner parts of the impact, lubricate with W-D 40, and reassemble.
4. I'm all out of ideas.. If that didn't fix it, I'd go get a new one.
Best of luck, --W/D--
Have you added any air tool oil in awhile?

I di add oil before i tried to use it. It hasn't been used in along time thou. Its like when you put the air to it the throttle lever doesn't do anything. Like there is no air even connected to it. It basically just flops back and forth
It has plenty of air pressure to it. i oiled it before i tried to used it the first time. I started to take it apart, but got as far as the ball bearing in the back. I couldn't really figure out how to take it apart from there. Plus, i thought i had figured it out. The "spring" and the "throttle valve" weren't in the right order. So that was another reason i didn't try to hard to go any farther in taking it apart. But nooooo, that didn't do "squat" for it. The "throttle lever" just moves around like there is no resistance from the air being connected. Its like there is "no air at all conneceted to it". I hope this all makes sense?
I'm not sure if anyone had it apart or not? I had forgot that i even had it, so its been awhile. But, looking at the diagram it appears to be put together right. So, who knows whats up with it? Thanks for your help. Carlene
