Hi, when i load the shaft it gets hooked up. However when it comes to pulling the trigger it does not fire. I tried to rotate the screw that is present under the trigger guard, but when I rotate it to one end there is no trigger movement (as if on safety), while if I rotate it to the other end there is trigger movement, but the gun still doesn't fire.........Pls explain a bit better the problem.....does the piston get hooked up? can you pull the trigger and the gun doesn't fire? the trigget got stuck?
I own cyrano Evo HF 100. Use couple times but now the trigger get stuck its look like safety never release...even the locking in normal position the gun still can't fire...anyone can help me to resolved this problems? Sorry I'm new in this forum.Hi all from Libya. Well about 3 months ago I bought a Mares Cyrano EVO HF 90 and was working like a dream. I had to go abroad for a few weeks and cleaned the gun really well and sprayed WD40 over the all important parts. I also left it fully pressurized, but unloaded. After I returned (3 weeks or so), I went for a dive, loaded the shaft and missed two good shots because the gun wouldn't fire. I figured there might be some kind of dirt, and eventually depressurised the gun completely, blew pressurised air into the trigger area just in case there was some dirt, and gave it a few shots of WD40, and pressurized it again. I didn't try it out as I was on land. Yesterday I went diving again and the gun would not shoot. I took a screwdriver with me and turned the sensitivity screw in various positions, but the gun, although pressurized and loaded, will not fire even when the screw is set to the position which allows the most trigger travel. I am stumped - what could it be - I don't trust any workshop here in Libya to do any repairs - and prefer to do it myself. Any ideas guys?
Thanks.
Thanks for sharing.When Mares installed the sear lever to sit at an angle it was the equivalent of filing the sear tooth to a slight angle, and all their problems stem from there. All side mounted line releases close coupled with the upper part of the trigger need to be checked for synchronisation of the release action. To do that you need to cock the gun at the pressure you will be using the gun and place the gun vertically with the spear pushed into a block of wood on the ground. You then hang a separate loop of shooting line with a weight on it like a lead fishing sinker on the line release lever, then bracing with your full body weight against the gun pull the trigger and control the gun rising up on the shaft. The weighted loop of line must drop before the spear is released. If it drops before then you will have problems. Wind out the trigger sensitivity screw a turn or two and then try again to get the line release happening before the piston unlatches. Because factory assemblers don't check for this you need to do it yourself. As the force level from gun operating pressure determines the opening action on the sear lever tooth you need your usual gun pressure for this test best diamonds veneers, not just a few psi in the gun.
Make sure you completely master how you do this, loading guns on land is very dangerous, keep tight control of the gun and point it downwards immediately it is cocked to shoot. Don't trust the safety, it only blocks the trigger, not the sear lever.
