My gun isn’t taking in fluid. I’ve cleaned out the line and filters. My pump is a Graco falcon series 699a and the gun that I am having problems with is only 3 months old. It’s a Binks aa1500 air-assisted airless spray gun with tip size 01310. I am spraying 2k poly but as of recently sprayed only Bernyl reliant with this gun.
From contributor J:
Can you get thinner through the system? If thinner won't go through, take your gun off the hose and check to see if thinner comes out. If it does then your gun is clogged. If it doesn't, take the hose off and replace it and try again. If thinner comes out then your hose was clogged. If it doesn't your pump is clogged. Take the foot valve off and see if the lower ball check is stuck.
