Hw100 losing air

[countryboy 0]

Hi all , just got it out and no air on gauge ,topped up and can see gauge dropping as I sit with it, 

is this something I can fix or is it back to shop for repair ?

I cannot see or hear where it’s coming from either.

 

thanks

It will be either the fill valve or the oring where the cylinder screws into the action, easy fix, I've just repaired 1 for someone 2 days ago, if you were local I would have said fetch it over !

Put a bit of washing up liquid in the fill port on both sides if its not that chances are its the little o ring that sits behind the air cylinder

to get to the little o ring you will need to take the stock off and unscrew the cylinder off

you will here a sharp release of air but dont worry you do not need to decant the air out of the cylinder

when fitting the cylinder back on put a little grease on the o ring first .

 

if its leaking from the fill port you will need to decant the air first

then strip the cylinder chances are its just a bit of dirt getting under the o ring in there
