just got some airtool accessories. air ratchet,chisel, impact gun.got them in a door crasher, 62 pcs set campbell hausfeld for 99 bucks couldn't resist. it says to use 90lbs at the tool, so do you have to set the tank psi higher to compensate for any loss of pressure from tank to tool?what psi do you run your tools at? not quite sure how to install chisel into gun, do you have to remove the big spring off the end of the gun to install chisel then wind spring back on ? the instructions didn't seem clear.(to me anyway). I noticed at the bottom of the tools next to the airline fitting ,looks to be a air regulator valve, is this to control the tool speed? told you I need a lesson, I'm use to no air tools and skinned knuckels, thought I should get a little more hightec and go air. thanks in advance

 

Most air tools are rated to operate at 90lbs pressure at the tank, most people, me included, run their tool at whatever the compressor is set at, up to 175 lbs. I would recommend a regulator setting of 125lb max.
Use 1/4 inch airline up to 50 ft, 3/8 in, airline if longer, you won't have enough pressure drop to worry about power loss.
Drain the tank on a regular basis to keep water out of the tools, give them a dash of oil each time you use them and they should last.
Enjoy your new tools, you will wonder how you got along without them.
The chisel is inserted by pushing the beehive spring to the side far enough to insert the chisel.
Many tools have a built-in flow valve to regulate the speed of the tool

 

Air Tools require air tool oil.
Minimum oil prevents shooting it all over the place.

Oilers are available that hookup inline usually at the compressure.

Sanders get very little oil.

Water traps are available like an oiler ,these are used for paint spray guns.

as mentioned : Always drain the water out or the tank will rust.

 

thanks guys. I'm going to go impact something or chisel something off just cause I can now, look out rusted bolts

 

> so do you have to set the tank psi higher to compensate for any loss of pressure from tank to tool?

Yes, usually 10 psi more. For impact tools you want to run at a min. a 3/8 hose so you can move a large volume of air. On impact tools, volume counts more then psi. I was taught to put a chuck on the end of the line and check the pressure with an air guage to make sure the delivered pressure was exactly 90 psi (30 psi for blow off tools).

> what psi do you run your tools at?

Usually 90 psi.

> how to install chisel into gun

Disconnect it from the line so you do not put a chisel through your hand or worse face.

Turn the gun so it faces up. To insert a tool, insert the shaft as far as it will allow, then use the chisel to bend the spring to one side so the ridge on the chisel slides under the spring retainer.

Do not test the tool's force without it being in contact with an object.

> do you have to remove the big spring off the end of the gun to install chisel

No! See above, just push the spring sideways with the tool.

> is this to control the tool speed?

It controls how hard it hits. Handy when doing body work and you do not want to poke a hole in something.

Note that the end of the chisel may be deformed and you might have to grind down ridges to get it to drop easily into the air hammer.

 

Never install an oiler at the compressor. You will end up with a dirty hose and a dead tool. Most inline oilers are made to be set up no more than ten feet upline from the tool. Water traps are not used exclusively on paint sprayers, they will also extend the life of your air tools. Rebocardo's post was dead on, slightly higher pressure at the regulator is fine and will compensate for any pressure loss in the line. For your tools, run a 3/8" line with 1/4" NPT fittings. If correct pressure is essential as it is with painting, run a dryer followed by a regulator no more than ten feet from the tool. This will let you know exactly how many PSI you have.

Last point: Don't skimp on quick disconnects. The good ones are more expensive, but worth it. The cheap run-of-the-mill disconnects will leak, snap off at bad times, break, they're worthless.

 

I got a inline water trap with my compresser, were about should I install it, at the tank, half way down the hose, or close to the tool? say what other cool air tools can a guy get?

 

I run my compressor tank at 125 and my hose pressure at 90

 

I've seen people run dryers in alot of different places. If you run it at the compressor, you'll stop most of the moisture from entering the tool. If moisture reduction is a big concern, such as with painting, you can run a dryer on the line and a separate, smaller filter at the tool itself.


As far as other air tools go, it's really whatever you want. As long as you have the air to push it, the sky's the limit. We already mentioned air hammers, aside from just cutting things you can also get a set of pickle forks that will attach to th hammer. Makes pulling suspension components much eaiser. You can buy all different kinds of air sanders, but be warned, they use alot of air. Air reciprocating saws, drills, screwdrivers, bottle jacks, grinders, whatever you want. Air is an awesome power source when you have enough of it.

 

The tank pressure even if set FULL BLAST WILL NOT EXCEED THE COMPRESSOR'S LIMIT !! It's the "working" pressure that you shold be conserned about, that's the REGULATOR, set it at the MAX recommended pressure of the tools your working with for best performace.

 

Don't squeeze the trigger on that air hammer without having the chisel touching something. It could come loose and go flying.
