Adam's Paint Sprayer Repair

Hello friends and followers, today I want to talk a little bit about spray guns.
What you see here is a needle out of a Graco Silver Plus airless spray gun. This particular gun is off a Graco Line Lazer III 3900.

You can see the ball on the end of the needle is worn with pitting and it's no longer smooth. As the ball needs to seat against the carbide seat in the diffuser on the end of the gun, this needle will no longer hold pressure.

When your gun spits, it's because your needle is not seating against the seat. Debris or wear will both cause this issue. A quick repack and pressure test, and this gun is back in business!

Tis the season of, can you squeeze in a few more repairs before the end of the year?

Late this summer, early fall I was down below 10 pumps to repair for the first time in 8 years. I had hustled and finally gotten ahead and thought to myself "I might be able to get a few home/shop repairs completed this season. Well, it didn't last long....
Here are a few winter tips;

1. It doesn't matter if you have liquid in your pump that won't freeze, if you have an electronic pressure control your sensor needs to be kept above 40°. Pump saver, RV antifreeze, paint thinner etc. they will keep your pump from developing corrosion or rust, but you must keep your sensor warm.

2. Now is a great time to get your maintenance caught up, stock up on tips and filters, and get your equipment into storage mode. Top off your fluids, add stabilizer to your fuel, and fog your carburetor.

3. If you are worried about getting invoices for work/repairs on your equipment before the end of the year.... Have your shop write you up a deposit towards your repairs and pay the bill. You can square up after the beginning of the new year.

4. Now is a great time to check in with your coatings rep to see what new products are on the shelf and try them out in your shop before the spring.

Have a great December and a Merry Christmas!

This is the hydraulic tank cover off a GH230. My customer brought his sprayer in explaining that one of his employees ran into the machine with a UTV and broke the tank. Just when you thought you've seen everything...
