Had one for a short time befoe i seen the light and got a 12l 300bar bottle.

When i used it on my s410 i had to cock it first. And obviously make sure the bleed valve was closed before pumping.

 

Is the needle moving on the pump gauge.

 

First 75 to 100 bar should be relativly easy to pump.Then it gets a little harder,that is actualy when you start filling thr cylinder

 

hope this helps as i said only had the hills pump for a wee while

i was always told these are no good for your gun as they are not filterd properly and you get microscopic peices of grit ect through the gun and it messes it up in the long run!!!

 

is this true i can only go on what i was told??

[cometa300s 20]

the needle doesent move unless i pump realy fast wil this change when i get to about 60 barr as stated above.

 

thanks guys

Sounds like the pumps working ok so the air must be escaping somewhere? as above ensure the bleed valve on the pump is closed, the pipe is tightened properly and the fitting into the gun is inserted correctly. Does your gun have a safety feature on it to stop you charging it's whilst cocked or uncocked If it still doesn't work then may be worth visiting the gun shop?

As long as the needle dosent travel back to were it started from,when you stop pumping.Then the pump is fine.

 

If you are having to pump very fast to get the pump gauge to read 60Bar,then it sounds as if your gun cylinder is empty

before you start.

 

That would explain why it seems you are getting no whare when pumping very fast.

Never tried it with my s410 but was told it was dificult,as you cant get the required pressure in the guns cylinder to rise quick enough to close the valve.

 

If that is the case you need to use a dive cylinder. The trick with these pumps,is to never let your gun go below 100bar

Best to do your pumping after a shoot rather than before...dosent sound right

 

Gives you time to get your breath back

I've got a pump for the PCP's...................in the cupboard where it's feckin staying . Moisture has always been an issue with them and hard going if the buddy bottle has a fair capacity is the other thing.

 

Only use mine in an emergency, like when I've a flat on the mountain bike

[cometa300s 20]

the needle only goes up when im pumping when i stop it goes back down. i think it is because i have to much air in the cylender to push the valve open. so im just going to wait till it realy needs pumping up and give it a go.

 

could this be the reason for it ?

 

thanks for the posts guys

make sure the bleed valve is closed tightly, push in the adaptor, start pumping it should fairly quickly reach a point at which it appears that the needle isn't moving as the pressure equalises between the cylinder and the pump, carry on pumping and slowly the needle will move up, pump upto required pressure, slowly release the bleed valve and remove the adaptor

 

if you cannot get any pressure into the system then (not sure with the ultra) you may have let the pressure drop in the gun air cylinder too low to hold the valve closed when you pump and effectively you then pump forever without it ever filling, if this has happened a dive bottle will be needed to fill it - its important with some guns to keep the pressure above a certain level - i have a Ultra, i know when its full to about 200bar i can get about 35 shots out of the cylinder, at which point i always refill

 

otherwise i presume a leaking seal somewhere on the pump or fill adaptor ?????

[cometa300s 20]

i will just let the preasure drop in the cylender drop a litle bit then give it a go i will kepp you all posted.

 

thanks for the help guys

is your gun s410 ????? if its a bsa ultra ive heard theres diff way to the norm to charge it ....

it should be stiff to pump my pump is stiff ish at first then gets harder as you get more air in ... ....

is your pump new ?

i have a ultra i just plug in and pump !

[cometa300s 20]

thanks for that celticwar i think it is because there is still to much air in the cylender could this be the problem
