newbieshooter Posted May 22, 2006 Report Share Posted May 22, 2006 I just got my new hornet today, however, when I'm filling it with a hand pump, air is escaping, and inbetween strokes it drops in pressure, if i wait, it goes to 0. I am using a Logun pump, is this normal? Quote Link to comment Share on other sites More sharing options...
roblade Posted May 22, 2006 Report Share Posted May 22, 2006 the rifle needs to be cocked when you try to pump it up, when your using a pump its generaly not a good idea to run the rifle right down to zero as it can cause problems re filling it using the pump. If that doesnt work, you have to either a) refill using a bottle to give it a quick blast or pump like mad!!!! RO B Quote Link to comment Share on other sites More sharing options...
Chezney Posted May 22, 2006 Report Share Posted May 22, 2006 Under the point where the host attaches to the pump, there is a screw... this maybe loose... you can tighten it with your fingers, but make sure that before you pull your adapter off your gun, you unscrew this screw again and let out the pressure. So tighten before pump, then loosen before you take adaptor out Quote Link to comment Share on other sites More sharing options...
newbieshooter Posted May 22, 2006 Author Report Share Posted May 22, 2006 cheers, how do i tell what the pressure is Quote Link to comment Share on other sites More sharing options...
Chezney Posted May 22, 2006 Report Share Posted May 22, 2006 If there is not a pressure gauge on your gun or on the pump it's quite hard... But on Logun pumps there is a gauge no? Quote Link to comment Share on other sites More sharing options...
newbieshooter Posted May 22, 2006 Author Report Share Posted May 22, 2006 yeah but when you plug it into the gun, nothing comes up Quote Link to comment Share on other sites More sharing options...
SNAKEBITE Posted May 22, 2006 Report Share Posted May 22, 2006 yeah but when you plug it into the gun, nothing comes up You obviously have no pressure! It sounds like either a ) You have a leak. Tighten all clamps hoses etc. b ) You are down to zero pressure which means there is no pressure holding the hammer closed so all the air is escaping as you pump. A blast from a diving bottle is needed. In future do not let it get so low on air! EDITED TO GET RID OF SMILIE!! should be b ) Quote Link to comment Share on other sites More sharing options...

NickHead Posted May 22, 2006 Report Share Posted May 22, 2006 I don't know wether this will help I have a quick fill adapter on my BSA Ultra. If I use a manual pump I have to remove a small allen key in the quickfill adapter ( I assume this is a restrictor for high pressure use). Maybe you have the same allen key in yours therefore restricting the amount of air from your hand pump. Regards Nick Sorry about killing the thread, somehow i have a habit of his happening. I don't thiink I should post anything anymore..... Apologies again... Quote Link to comment Share on other sites More sharing options...

EDITED TO GET RID OF SMILIE!! should be b ) :o good advice, but not neccessarily due to no pressure. as you pump, you may eventually hear a 'click' or other change in sound coming from the valve as it opens due to the pressure equalising either side of the filler, this is the point where you find out what pressure was left in your gun cylinder. i'm not sure about your gun, but if you can remove the cylinder then do it if you are to fill it from empty, this should ensure all valves etc. are closed prior to filling.
