Ait Tool Failures
Hi all,
Has any one any experience of air tool
failures .
I've had 2 impact wrenches and 2 ratchet wrenches all failed in on the first use or 2 second time out. The problem seems to be when the bolt
reaches tightness i.e the unit goes on ratchet and after that it doesn't work . Air passess thro the tool but nothing else happens.
All the tools were from different manufacturers and so can't blame a dodgey batch.
The compressor pressure was also well within the stated operating pressure range and the units were oiled before use.
Any help really appreciated as this is causing me a fortune in replacement units !
Surely these tools can't be that sensitive.

I have sometimes had air tools jam. Normally I found you can free them up (by yanking on the rotating/reciprocating section until it clear. And make
sure you always use the correct air tool oil.... Otherwise no, I would not expect them to break so readily.

No not from Aldi or Lidl
1 set was from S.I.P and the other set was by AM-Tech.
Are they sensitive to the pressure operating pressure range . It's almost like a seal blows in the unit somewhere so air justs vented without
passing into the unit.

A lot of tools these days are manufactured in one huge factory in China and sold under different brand names....

Maybe you have over oiled them. This can happen and the vanes on the motor stick in the slots. I did this to my ones and had to strip it and clean the
gunky oil out after this they have worked fine and I no longer obey the oil daily instructions

If its the same on all of them maybe its something else ?
Have you a small bore air line, if so you may have the pressure immediately but not the FAD to power these properly.
Also are you straight on the tank or going by a regulator, air tools go straight in.
I oil mine with a few drips of 3in1 oil down the air feed with the trigger open, seems to do the job. As above heavy oil clogs them up.

In 40 years of using air tools I have never had a decent one fail . The only failures have been cheap items .

mine does that if i use a small bore air line, unless you use absolutely maximum pressure. If it is that dont forget some of the screw in connectors
are restrictive as well as the hose.

My Aldi rattle gun is still going strong, a squirt of 3 in 1 type oil before use is all it gets. It must be luck of the draw I guess.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
