CAT gun issue3/23
I'm having an issue with a CAT bobcat gun on a H2O AAA setup. It's about 3 yrs. old. Just started doing this recently. I'm having trouble getting an even spray pattern when spraying my finish coats of either pigmented Agualente or clear Sayerlack. I've tried both my 411 and 413 tips of which I bought new ones thinking they were the issue, no luck. I replaced the upper needle (air/pattern) as per manufacturer's guess at the problem, no luck. I'm wondering if it might be an air cap issue? I've soaked and cleaned everything I can possibly clean, don't know what else to try short of buying a new gun at $500+. Any ideas from other Bobcat owners? Also tried playing with pressure and air until blue in the face, although I never had issues before recently with these finishes.
check the white seal on the fluid outlet of the gun, it is thick and is not the seal inside the tip, if it is nicked or not even there your pattern will look like crap
stupid question but is your gun handle screen in good shape or new? and of the correct mesh size for the material your spraying? if some of the mesh holes are plugged or the mesh size is to small can really affect your flow and pattern
Don't replace the gun! It's completely rebuildable and not that hard to do. First call CAT's customer service. The few times I've needed their help, they've been awesome.
Like someone already mentioned, check the inline filter and the pickup tube filter. I've noticed that the pigmented Agualente tends to clog both.
Use the tip cleaning needles to clean all of the little aircap holes.
Thanks for all the help guys. I did check the filters and they were ok, but Herb, you hit on the answer. The white ring needed replacing and luckily, I had one on hand. Back up and spraying and after seeing results I think it's needed replacing for a while. Thanks again.
We own and use 3 of their Cougar guns, and 2 Jaguar.
I intentionally keep enough parts on hand to rebuild at least 1 gun from a raw chassis. I have a tool box with each part in a plastic baggie, with part number written on a piece of paper, and instructions to "order immediately when you use this one". I have a local vendor fortunately.
I always suggest keep on hand at least one full rebuild for your gun on any of the parts that you remove with a wrench, or wear out, etc.
I do the same for the air motor and fluid motor, but that's because I've rebuilt them and can do it if needed.
CAT is a good company with good customer service.
