How to Clean and Lubricate the Krause and Becker Electric Paint Sprayer

First, make sure that you have unplugged the electric paint sprayer from an electric source for safety and make your work easier as a whole. Then turn the pressure knob speed to medium. Remove the tip and tip housing. Then put it into a bucket with water and brush it with the bristle brush. Then set it aside. Then transfer the siphon hose and the primer tube into another bucket of water and brush it with the bristle brush until all of the wet paint comes off. Turn on the sprayer again to double check it and see its performance. Then run the water in the bucket into the system through the spray gun so that it will flush out the paint that is inside it. Then set the function to prime so that the paint remaining inside will be flush out. Flush out the paint until it becomes thin. You can put it in a separate bucket because that paint can still be recycled. This is the first run so let it run for a few minutes and all of the wastewater with thin paint will now be flush out again quite convenient I might say. It should be in the waste bucket. Then set again the spray function to spray to completely flush the paint hose and the gun. Spray the gun into the bucket where there is recyclable paint. When the gun starts to release a mixture of thin paint, transfer it fast to the waste bucket. Run it for a couple of minutes. If you see now that the gun is releasing clear water, you can now turn it off. Then remove the gun to clean it further later. Drain the hose using the rag to wipe off some paint that is left. Get another bucket of clean water and repeat it again to be sure that the pump is really clean inside.

Next, use the wrench to disconnect the spray gun on the hose attached to it. But before doing it turn the spray function to prime so that the pressure will be released on the other side. Then unscrew the nut using the wrenches. Yes, you will need the help of two wrenches. Once the gun was separated from the hose, put it now into the bucket with clean water where other parts are also submerged. After, try to check the hose if there is still some paint in it. If it has, then set again the spray function into spray to flush it out and clean the hose. Once the water comes out if the hose is clean then its fine now. You can now throw the waste water accumulated into the buckets and refill it with some clean water. Then try to flush it again with the clean water to make sure that the whole system is now clean inside.

Let’s clean your beloved spray gun! You can use a bristle brush to clean it, especially the inner parts. Then disassemble the spray gun for thorough cleaning. Take the gun grip because it has a filter inside that needs to be cleaned carefully for maintaining. Use a wrench or you can use two wrenches to make it easier to screw off. Be careful when you already loosen that part because it has washers and parts that you need to not to lose. The gun has parts that you need not disassemble. It is the piston, spring and the cylinder is one piece so do not try to disassemble it. Then clean everything with clean water. You can also use the bristle brush. Next thing you should do is take care of the handle and clean it.

Lubricating is simply putting some oil into the unit to make it run smoothly and preserve it. This is very necessary if you will store the unit for some time like weeks or months. Any oil can work on this like compressor oil or pump oil.
