Air Impact Wrenches
Xtremeteam:
--- Quote from: "sharpshooter" ---I use them at work. I have a Snap-On 1/2" drive, and i can remove truck wheelnuts at 450LbFt. Alot depends on the supply. As has been said before, you need a higher CFM to run a windy gun, due to the large capacity of air they use. Use the largest bore hose you can too. The small compressors from Screwfix and such like, I.E. 1.5hp ones are ok, but only for short bursts. You really would notice the difference with a 2hp or above. Also, the larger the storage tank the better.
You should oil all air tools Daily, and dont use thick oil, as it will cause the gun to Hydraulic lock. Use proper air tool oil, or Hydraulic oil ive found is good. Also oil them lightly when you have finnished using before storing. :)
Hope this helps.

ive got a sealey 1/2" gun which is ment to be 510 Lbft max,i use a 15w40/5w30 mix to oil it lightly & every 6 months strip the gun down n empty the chamber of any excess oil & away i go again

Did it come from "machine mart" cos I have one that sounds like it's just the same as yours :shock:
Compresser I use is DIY quality, not a big industrial monster, it's specs are
7cfm air displacement
50 litre air receiver
1.5hp, 230v
8bar (115psi) maximum working pressure
Does that sound OK guys or is it a compressor problem

Sharpshooter:
Like i said. The smaller compressors like you mention may struggle, due to the guns swallowing loads of air. But they should be ok in shorter bursts. I used my 9cfm snap on one on a 1.5 hp 25ltr wolf from screwfix, and undone the wheelnuts on my 110 ok. Just took a while to build the air back up. :D
Wanderer:
Is there a regulator in line?
Can you up the pressure?
Although as previously mentioned they also need the CFM as well as PSI.
I'm old school.
Try spinning the socket in reverse by hand just before you pull the trigger I've had DAs that wouldn't start without knocking the pad round in reverse.
Hangover:
Check to see if any air is blowing out around the trigger
mechanism there maybe a o ring or something gone in there,alternatively if it's a cheap £20 gun bin it as ive seen them just fall to bits inside.You should get a CP one at a car boot sale for about a tenner.
