My paintball wont stop shooting but it has nothing to do with the co2 tank help?


The sear is not catching the bolt and resetting it properly. Or, there is not enough air pressure to push the bolt back to its original position. I would take it to a gunsmith. Parts fly out of a Tippmann if you open it up.

Doesn't stop spraying after trigger is released


Dear Peggy,
You can have a problem with the valve at the gun which is sticking open. This valve can be OK without pressure, but with pressure it can stick open. It is very easy to make sure, by attaching a good gun or a new gun. In simple words...replace the gun.

Problems pressure fluid


The air hose between the tank and the gun is clogged, possibly by a bug nesting in it. The second place to look is the regulator on the pot. Insure that you have free airflow from there to the gun.

Hello there.My Karcher pressure washer motor constantly runs with no pressure coming out of trigger gun.I have tried another gun with the same result.The motor should stop/start when you press gun.The...


The valve that admits more water to be compressed is stuck. It is likely the O-Rings on it need replacing. No water to the pump, no pressure!

The motor will stop when pressure is up to the designed pressure.

Do not know how to work power washer


Dear Carrie688,
I cannot for sure understand your problem. You say, you do not know how to WORK power washer. Does WORK mean FIX...or USE???? I will assume that you wish to know how to use it.
First without water connected and without gun connected...switch on the machine. If it turns, then this means the electric motor is OK. Now connect the hose and gun. Connect water supply. Now always start the machine with gun open. This will help to remove air from system. When pressure builts up, close gun, and machine must stop instantly. If machine does not stop, open the gun again and switch off the machine. If the machine continues working when the the gun is closed, this will result in a lot of damage. I do not know what model you have, because also there are old models that when gun is closed, the machine keeps running. I assume your model is recent. So the machine will stop when gun is closed. Now when finished, switch off machine and electricity. And most important release pressure from gun. Do not store machine with pressure still in it. This will damage machine and it is not safe.
Now if you have detergent, this can only work on low pressure. There are bigger machines that detergent works on high pressure. But the normal system is that detergent works on low pressure. Also before storing, pass fresh water to remove all detergent from pump of machine. Never store a machine with detergent in its system.
Regards,
Fulltech.

Dear Aliciaashwor,
I am assuming that the problem occurs when the gun is closed. This problem is due to a fault in the spill valve. When the gun is closed, pressure pushes this spill valve downwards and puts off a micro switch. Now this spill valve has "O" rings. If the O rings get worn out, the spill valve starts going up again and switches the machine on. The pressure is built and the spill valve goes down again to put the machine off. And so this goes on....ON OFF ON OFF. The spill valve must be changed. But if you see that you have pressure when gun is open, all you have to do to stop, is switch off the electricity before you close the gun. This can be done as much as you want, because no harm is done. So open the gun, switch on and work. To stop switch off and after close the gun.
