hi all,

 

been a while since i was last on here but getting back into shooting and discoverd my hw100 is losing air from around 180bar to 50 bar over night and it also seems to be firing weaker than i remember it last year

 

any idea what could be causing it? if its a part change i could probly do it myself but i dont know a decent local gunsmisths near me im in hoddesdon hertfordshire now

Hi John,

 

If you remove the cylinder fill it up to 200bar and leave it overnight, will the pressure still be there?

tonight is the 1st night ive taken it out the gun pumped up so tomorrow morning i will find out for sure so far ive only noticed it while left in the gun

sounds like seals to me - just replaced all mine and that cured similar symptoms.

where did you get them from mate? and how much if you dont mind me asking?

did you need any special tools to do it or just allen keys etc?

 

cheers

Cheers mate will do, also an update is the cylinder is still losing air even though it's not connected to the gun it's lost about 10bar in 2-3 hours I guess that rules out the seals? What's my next step? Sorry for all the questions it's my 1st pcp and 1st problem

this morning no air leaked and the little bit last night must have been where I screwed it in and out couple of times so I know the bottle is Infact holding pressure fine

10 bar in 2-3 hours could this just not be down to a fluctuation in temp??? taken from a gun bag in a warm room, and taken into a colder room???
