Impact wrench problem
Finally got to the garage this morning to play with my new Aldi air tools and the impact wrench doesn't work.
When you hold the trigger it just exhausts the air from around the trigger.
Its unlikely I'm doing something wrong but does anyone have any ideas?
Otherwise I'll take it back and get another.
Thanks

Sounds like the forward/reverse is halfway inbetween, effectively in neutral
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Decided to take it apart. 
Internal friction was too great to actually power it 
I think the backplate was on too tight so the air pressure wasn't great enough to overcome it. I couldn't turn the output by hand, but
could with a spanner.
so took it apart, put it back together again, and run it a few times tightening the backplate in between. its now as tight as it was but works.
Thanks for your help Mark.

I got one of these that also seems to have the same problem.I was going to take it back also but might have a look at it first.

paul If I were you I'd loosen the backplate slightly then try it. No point taking it all apart, though tbh honest its not difficult getting it
back together.

Be sure to put some light oil in the air inlet as well - that really helps to loosen them up...

Try a bit of wd40 up the inlet to get it going. Theyv probably put it together with lube thats gone sticky. If it goes make sure u get some proper
oil up it quickly. I bought an aldi air drill havent tried it yet. Has anyone bought the air chisel??

I got everything except the chisel.
All were fine except the impact wrench.

As I said elsewhere - impact wrenches need a LOT of air - I had to get a larger bore hose to get mine to work properly. Useless on a coiled hose,
fine on a 1/2" bore hose. I've got a big compressor, and it charges up quite often when I use this thing!

Impact driver seems ok but had to take apart the reversable wrench as it stopped working after a few seconds of working.
I reckon they are just tight and will run in.

I must admit David when I used it to remove 3 10mm nuts on the tintops exhaust heat shield i was less than impressed.
gonna have to get a bigger hose I guess.

I didn't realise until I got a book on air tools - first 2 things it says about impact wrenches are:
1. Get a large-diameter hose
2. Use the correct sockets (ordinary ones can shatter)

I found my impact wrench worked fine with the supplied hose, having a little go on some m12 studding anyway (bit chunks into the nuts).
but then the second compressor seized after a couple of hours light playing around use (the first one had a broken regulator casting)
so I took it all back today and got my money back. ho hum.

im sure my cheap one came with no oil in it, or a bung that needed removing.

yep, it had oil up to the middle of the sight glass, and I removed the 2 travel plugs and installed the air filter and breather. and the breather
wasn't clogged with moulding flash like the airbrush stuff.
think I connected all the right dots unless someone knows better..

I just fitted a pcl fitting to my rattle gun and tried it and it works and still fits in the case Instruction says to run it at 90psi and I have a
3/8" hose which ran it fine.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

But 3/8" is quite a large hose, for DIY compressors... I think that's what mine is.

My 2c to deepen the knowledge pool.
I bought one tat didn`t spin, disasssembled and found completely oil soaked. wiped excess oil and reassemble.
It is working OK now.
Beware of what you wish.. for it may come true....

ahh the wonders of cheap crap tools!!!
I bought a slightly more expensive, but still chinese, impact wrench, and depite what it says about lbft ratings on paper, it won't touch stuff
that my big breaker bar will with no real trouble..................
i.e. kinda pointless! Speeds up dismantling I will admit though

Mine undid the sprocket nut on my engine without locking it or putting it in gear, something I couldn't do before so I'm happy with it. As
long as it lasts long enough to tighten it back up that is . I have a breaker that extends and a 6' aluminium scaffolding pudluck for
emergencies but it is awkward to use them in some situations.

Mine is ok with a short air line and some oil workied through it. I did manage to remove an alternator pulley that wouldnt come undone easily with a
normal ratchet so think it will be usefull at times .

This was the main reason I bout mine, to undo the crank pulley nut an XE engines.
These are done up to 250lbft plus 90 degrees, o probably over 350lbft..............
impact wrench has absolutely no effect at all!

It's undone the flywheel bolts on a Zetec engine today as well. I think for the money it's paid for itself now.
