ATX100 tweak

[JohnK]

Had my ATX100 regs serviced before Xmas and have noticed a little "freeflow" after a few uses. When I say freeflow I mean its just very slightly hissing. Now I have read somewhere that once new seals have bedded in the regs might need a little tweak. I have removed the slight hiss by closing the LD thingemyjig (LH outside adjuster when regs are in me gob.

Can I carry out a little tweak so I can open up the adjustment again

I can take them back but fancy doing it myself.

Any advice ??

It would be worth seeing if there was a slight creep on the interstage pressure.
You can buy a small gauge that will fir into your bcd hose if the IP goes over the figure in the document the other correspondent sent then you need your fist stage looking at.

Just pop them back to whoever serviced them and I am sure they will 'tweak' them for you.

Sounds about right. Back off the cracking pressure knob so they stop. You have to do this with Apeks regs after a service.

If none of the above works, take the hose off thr 2nd stage look inside where the hose came from, and you will see an allen bolt.
Get an allen key of the appropriate size,place inside said bolt and turn about1/8 inch clockwise replace hose and check.
If it still weeps repeat process.

Push the purge button in while turning the allen key or you will cookie cutter a hole in the seat.

All the previous might work but it needs setting correctly.My advice is to return it to where it was serviced so that they can do it correctly and you then have someone to come back to.It is their responsibility anyway and you have paid after all.Imagine if you do everything everyone has suggested and you cock it up you will be back to square one at best.

I'm not saying don't return it to the service center but I did twice and they didn't fix the 'hiss' in the long run. I ended up removing the LP hose and turning the flat screw anti clockwise a little ~10 - 20 degrees (to the left). This wound the arm which the purge button depresses - in. The seat had I presume compressed and this pushed the purge arm out to the purge button and then lead to a slight purge. I had Apeks Atx40 but I don't know if the ATX 100 have the same flat screw or the hex the previous poster mentioned.

I would say that everyone who owns an Apeks reg ought to be able to do this themselves.
