Gun pulsating/vibrating

[Pat Norman]

Do you have more than one trigger gun / wand ? Is this problem on all guns? I got one gun that gives similar probs and will not downstream. All other guns do fine. I think some debris must have got in the gun. Gotta look at it and see if I can clear it out.

Pat, I have two machines. I use the same gun on both, it only does it on one machine.
I'll try another gun with that machine to be sure.

David, either your flow has dropped off some or the unloader is going bad. How old is it? We can maybe replace the bypass orifice for a smaller one to stop it.

It's a year old. I noticed it would pulsate on start up, after I pulled the trigger the first time it would stop. That's happened for a couple of months. I didn't think much of it until now.
