A5 trouble

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Few months before winter last year I bought my very first paintball gun/marker; the tippmann a5 since I had heard only good about the simple and efficient mechanics. Used it then loved it then until...this year. 

My tippmann A5 now has the EGrip installed on it(the one with the easy battery access...) but as of now i must have only shot around 20 bullets the first time playing this year since the valve's o-ring managed to "stretch" out of its place pooring the content of my CO2 bottle right out the barrel.

No problems there... a bit annoying but got a repair kit openned it, gun looked still in good shape since it was only used once... was oily enough. Today, the same problem showed up, this time i didn't get to waste even a bullet before the breakdown.

I dismantle the entire gun, even the trigger. Everything looked just swell and pretty much brand knew(exept that same o-ring of course). There has to be something I'm doing wrong or just not seeing since I have no idea what is happenning. To set up today i screwed the co2 bottle and then turned my Egrip on and BOOM!

Perhaps im not going through the proper steps to "ready up" my marker or...well I just dont know. Any idea?

A5, M4 6pos. stock, Dye Ultralite 2pcs barrel, EGrip

	If you have the Push pin in and the latch is catching at the tombstone, it can only be the valve or the tombstone itself. Find soneone to swap tombstones with and gas up, shoot a hand full of 'Paintballs' and see if it does it. If it does it again, try their valve and your tombstone if it does, etc. Nice thing about the A-5 is you can remove your tank and swap the valve out in a minute. The oring usually pops because the tombstone isn't far enough up into the valve. Look at the tombstone latch and push pin closely

	Thanks but I managed to find the solution so far. I wasn't cocking the marker before airing it. tried it today while cocking the marker, starting my Egrip and then airing it and fired a 100 rounds without any problems. I'll test it some more this week but so far it works... looks like i was just a poor gunsman:P

	You shouldnt have to cock the gun before you plug your air in.

	Actually whether or not you should "have to cock the gun before you plug the air in" can be a very marker dependent issue. It can even vary among markers of the same type as a weak/worn valve spring may not have sufficient force to properly seat the cup seal (even with the assistance of the air pressure provided by having a tank on the marker) against the pressure of the mainspring and rear bolt on the valve plunger. It is in fact a good idea to always cock a mechanical marker before airing up so that the valve is pre-positioned to properly seat when air pressure is applied. Not doing so will not generally cause any damage, but doing so is definitely easier on the internal mechanical components. Since the discussion in this specific thread was in reference to the A5, I have included an excerpt from the A5 owner's manual below with the pertinent information shown in blue text: STEP 2) Air Supply Cylinder Installation • Do not pressurize a partially assembled paintball marker. • First install barrel sleeve (see instructions on page 2). • Next put trigger safety in Safe Mode (see instructions on page 4). • Next you need to cock the marker by sliding the bolt handle all the way back until it clicks. Then release cocking handle. Cocking handle will slide forward. Marker is now cocked. Always keep marker in the cocked position when air supply is attached to marker. This will help prevent an accidental discharge. • To install the air supply cylinder, lubricate the cylinder valve o-ring with a little gun oil then insert the cylinder valve end into the air supply adapter at the back end of the marker grip (or remote coil on A-5TM STEALTHTM). Twist the cylinder clockwise into the adapter until it stops. Your marker is ready to fire once you switch to Fire Mode from Safe Mode. If the tank is full and you do not hear the air supply engage, the pin valve could be too short or the pin valve seal is damaged. Getting Started (continued on page Based on the majority of comments/advice I have noticed you offering I would highly recommend that you refrain from offering additional advice until you gain a little more knowledge of how paintball equipment actually works.

	Yeah, these things "slam fire". something similar to the way an M-60 works, the start position for the firing cycle is with the bolt to the rear.When you pull the trigger, it releases the hammer which strikes the gas valve.When the hammer is left forward it is pressing against the gas valve and could allow the valve to remain open a bit when you gas the marker up.Save gas, cock your marker......

	Dude, this thread has been dead for over two months; the original poster has probably solved the problem by now. Please don't bump old threads.
