S200 Mk2 Charging

Sun Dec 24, 2017 12:44 pm

Hi

I'm a PCP newbie here hoping for some assistance.

I've got an S200 Mk2 and I'm trying to charge it with a stirrup pump. The gun and pump have the old style male/female connectors - no gauge.

My problem is - although the pump gauge registers 180 bar, this just seems to be the 'in-line' pressure - there doesn't seem to be any air going into the cylinder.

When I bought it, it had been fully charged from a dive bottle.

Am I overlooking something obvious. It's my first PCP so I'm a bit of a rookie.

Cheers

Russ

It may be empty so you will have too cock it first if that doesn't work it may need a blast from a dive bottle to close the firing valve.

Ps welcome to the aaoc :D fill out your location in your profile you may have a member close by who can help you out with the initial charge.

or it may still be fuller than 180 - does it fire?

I must admit that I much pefer a scuba rank for filling.

Hi Guys - thanks for the responses.

It fires OK - shooting at 8.35 ft/lbs - was around 10.4 just after I got it and got round to buying a chrony.

Can't really justify a dive bottle - the pump cost £160 so it should be up to the job.

Could it just be a clogged fill valve?

Cheers

If you have over filled it you will have extra pressure holding the valve closed. I would dry fire another twenty times then try it over the chrony

£160 could have bought you a cylinder :(

Ran a series of shots which came out at 8.7 / 8.32 / 8.66 / 7.96 / 8.20 / 8.04 / 7.97 / 8.50.

Dry fired as recommended and next series of shots came out at round about the 9.60 mark, with a +/- of 0.3 over 6 shots.

So, we're moving in the right direction.

I've read what others have said about not being obsessed with the 'as close to 12 ft/lbs as possible', but would still like to see something in the 10.5 to 11.0 ballpark.

Is this realistic.

In an ideal world a cylinder would be great. But the ability to top up at any time appealed. Plus, I did some checking before buying the pump, and couldn't find anywhere local to top up a cylinder.

Swings and roundabouts I guess.

True enough :)
