I got the Horizontal model W31 , How do you tell if you got the auto drain?View attachment 464914

That's a vertical, without auto drain. There are several features to identify the auto drain model, some of which are solenoid valves (electronic 'blocks') where you have manual valves on the left-front of the compressor.

Those 2 black valve knobs on the bottom left are mechanical. Just like mine…

Thanks guys I got my Horizontal and vertical mixed up, To much work and not enough sleep will do that to me, 12 years ago when I was filling my great white it was 35 to 45 dollars from 3000 to 4500 fill , The cheapest was in Midland 38 miles away and the highest was in Odessa 20 miles away, Both took about 3 to four hours to fill bottle had to work me in just to fill bottle, Or you could rent one of those big 6000 psi nitrogen bottles for 300 a month with free refills.
Just FYI here in the middle of West Texas, And if you look at the big picture , I am getting off pretty cheap with the Alkin.

Make sure when you do crank up the Alkin - the mechanical knobs are tightened. Forgot to tighten one when I turned on the machine - guess I was looking at my phone timer too long, and the knob wiggled out and disappeared. Took me awhile to find it - without the knob it will leak air through that release. live and learn!

Yea, My knobs fell off when I was doing the 10 minute break in , The bottom one air came out fast, Scared the crap out of me had a hard time putting it back in with the pressure, Your not suppose to have the knobs screwed in while starting , Unscrew let it run then screw them in , That's what I read.

I stretch a long rubber band across both bleed knobs, it keeps them from vibrating out when open. It just occurred to me that a couple wraps of Teflon tape should also work. I’ve got 3 bottles to fill today, so I’ll give it a try.

 

[airgunmike56]

I a going to try the rubber band, But the teflon tape sound pretty good for a temp fix.
Thanks

Hmm...
If any of the bleeder valves are open...Just a crack.....
Let alone about to fall off......
You should hear the air escaping!!
Also you should notice the decrease in pressure build-up...If you are watching your gauge(gauges..)

This happens only when purposely running with the bleeders open, such as during warm-up with no load, or cool down when done with the compressor. I don’t know that everybody does that, but I do.

 

[Ca_Varminter]

I do the same to warm up or cool down... I leave the purifier closed... let the system build up pressure then crack open bleeder
on the moisture separator between 2nd-3rd stage (my old w31 on has the one...)
This keeps pressure up in last stage to eliminate piston slap/rattle!!
Don't have the problem of the bleeder knob falling off though...

Mike,
Did yours come with that valve for draining the crankcase oil? Have not seen that on any models.

 

[airgunmike56]

Yes mine came with a valve to drain the oil, Also a tube so you can get the oil out farther, I see the oil on the site is a little expensive but not as expensive as the Mobil one jet oil I had to use in the Shelden, The jet oil was like 35 to 40 a QT ,, Just glad I don't own a JET,,

That’s a nice addition to make oil changes simpler.

 

[rcs9250]

Nice.

I was thinking the same thing, and thought about ordering it. For the once a year oil change, I’m gonna rough it, ‘cause I’m tough like that!

 

[Skydivingmiami]

I'm going to try the rubber band method - its cheap and should work. thanks for the suggestion!

cool oil drain - mine is the standard version.

Shut Down Procedure.......
Once fill pressure is reached...Shut Down the Alkins
Then close tank valve
Now Flip Alkin's fill valve handle to close valve and vent air between valve and tank.
Bleed the moisture traps and purifier of any moisture.
With the fill valve still closed, turn on compressor.
Now squirt about 15 to 20 mls of compressor oil into the Air intake.
Run for about 1 minute, open bleeder on the traps and purifier.
Shut all valves, let compressor run a couple of seconds to build up a little pressure,
shut down compressor, open fill lever to expel pressure in hose.
Close fill valve, put cover on compressor

Whats the purpose of squirting oil into the air intake isnt that bad for the compressor and the whole reason it has an air intake.

 

[Ca_Varminter]

This is the procedure for Long Term Storage...
Since I don't run my compressor Daliy..
This is to protect the exposed metal surfaces with a thin coat of oil.....
I am not pouring a pint of oil... I am squirting a 15cc of oil....
Let the oil process through, build up some pressure, the open the bleeders....
Blow out the excess.....
