My HW100 is losing air ?

[huddies 1]

Noticed yesterday after not using my gun for 3 days the cylinder gauge is almost on empty. I took the cylinder off today and have placed a balloon over each end of the cylinder to check both the threaded end and the quick fill end. Neither balloon has any change. So now thinking its somewhere else. Would i be best to send it off to Hull cartridges or is it not to tricky to change the o rings. That is if thats were its leaking from. Has anyone had the same trouble or a possible cure. Cheers all.

if found that its a common place for hw100's to leak is were the hammer section bolts on

 

the bits outlined are the only bits with seals in the rifle mate and the little outline is the bit im talking about

thanks mate, looks a tricky operation?.

firly easy if u know how!

 

1- take mech out of stock

2- remove trigger unit 2x allen bolts

3- undo the 2 allen bolts holding the hammer/cocking unit to the air section

4- check/listen for leaks etc

5- if cant hear out and u feel confident to continue UNDO BOTTLE!!! then relise preassure out of chamber by putting hammer/cocking section agains it and shooting just to be sure

6- then undo hammer valve section! 2x allen bolts (circled section in pic)

7- take out insides but make sure u know order they go in or refair to the pic i sent

8- check all seals etc and replace any old or warn seals or just replace for added benifit

9- once all done reassemble in reverse and should be ok!

 

but DONT!!!! tutch the regulator! as it needs setting to a manufacturers setting and u cant unless u eather mark it and count threads or make ur own reg preassure guage like i did to get it spot on

 

IF U DONT FEEL CONFIDENT ENOUGTH GET SOMEONE TO DO IT FOR U OR SEND IT TO HULL CARTRIDGES
