First, I hooked the aircat up to my regular 50 foot air hose. Wasn't sure how much pressure loss but thought I'd give it try. I kept the gun on it for a while and no movement.
Sprayed some Maltby penetrant to help lubricate and remove rust off the threads. Came back 3 days later and still nothing :(
Called their support and they recommended that I crank up my regulator to 150 PSI to compensate for the long hose since the rating for this gun is 120 PSI for 1295 ft/lbs torque at the gun, rather than at the regulator. No luck.
If you read the instructions, they mention the following key instructions.
1. Don't use a hose longer than 25'
2. Don't use a quick connect at the gun.
Both of these things restrict air flow to the gun causing the gun to not perform at optimal range.
So to be safe, I bought a short 6' hose with 1/2" diameter, put on the adapters so that it's 1/4" npt straight to the gun and the other end 1/4" npt quick connect to the compressor. Set the regulator at 150 PSI
This is one insane bolt to remove because message boards were saying that you need about 1000 ft/lbs of torque to get this bolt off.
With the new setup, I can definitely hear and feel the amount of extra power.
At first, the bolt still didn't budge. It took me about 4 tries within the first minute and the bolt came off finally!
So my advise to you is to make sure that your setup is on a very short hose and you'll love this gun.
However I have 2 major complains with this tool. Ones that if not for the price point, would result in a negative review
1. This is the one that gets on my nerves. A lot. However they cut the output shaft results in a lot of socket wobble when the gun comes up to speed. Doing things like removing lug nuts will violently vibrate the gun to the point of it will stall out when I let off the trigger. That same vibration can cause the socket to slip off the stud and mar up customer's wheels if you aren't careful. I can't just pop the trigger and let the lug "freewheel" itself off. I need to stay with it for that reason. My co workers IR gun doesn't have this issue, even with the same socket. My 3/8 aircat does the same thing, I think it must be in their tooling.
2. Running on typical shop air pressure, 140-175psi static pressure, the trigger gets very touchy. Almost like an on/off switch. There is very little modulation in the beginning stages of the trigger. Add to that that it feels like the gun stalls out unless I give the trigger a firm pulse - like the air veins aren't catching. But then it spins up the gun and makes it difficult to "finesse" things
As I said, torque wise and speed wise it's pretty good. But there are some hiccups with use that are a real turn off. Especially the vibration part - that will wear out the sockets and the gun faster than anything
