Astro Pneumatic - Air Operated Paint Shaker (4550A), Blue

Everything went as expected.

Good build

Muy bueno

Secured it to my main table made from 4x4's using lags. Creates quite a rattle and the paint cans get looser the longer they go. Using the recommended shake times work fine, but don't let it go longer or you might lose a can.Setup was easy, but I am worried about the acrylic oil cylinder breaking one day. I made sure to install this unit so the air ingress is facing away from traffic areas and I ensured the hose is attached in as stress free a way as possible. I'm not sure how I could replace that part if it broke.

Works great, saves a lot of time.

I bought this for my husband. We have a classic car restoration shop and this is a perfect addition to the paint shop area.My husband loves it and says it works great.

Thinking the unit may not have been fully greased at the factory, prior to mounting it I bought a grease gun and tried to grease it. There are two grease lubrication fittings and both are the Zerk type. One is inside the housing, accessed through the hole you see on the topside, and recessed nearly 2". Though the motor shaft can be manipulated to get this Zerk fitting beneath the access hole, it won't line up directly under it. With some effort I managed to attach the grease gun nozzle to this Zerk but afterwards couldn't detach the nozzle. I found several websites addressing this problem and one very good YouTube demonstration at <[...]>. A straight pull will not detach the nozzle, one must twist and turn it down into the two o'clock position and then pull it off. The small diameter access hole in the housing doesn't allow for it and restricts nozzle detachment to nearly a straight pull. I then detached the entire paint can holder component to get it out of the way. A very strong buddy and I used blocks of wood and still couldn't get the nozzle off. The access method for this Zerk is a severe design flaw. I finally had to use a pry bar from the underside to get it off and returned the paint shaker to Amazon. I'm wondering why none of the other reviewers mention this issue. Either they know something I don't or just haven't tried to lub the Zerk inside the housing????
