3M™ Random Orbital Sanding Basics: Episode 5
Dan Bygd, Senior Technical Services Engineer, talks about factors affecting random orbital sander performance.
Tool Inspection Basics (00:40)
Tool inspection checklist: Is the paddle or lever working correctly? Is the backup pad spinning freely? Are all the connections secure and fit?
Oiling the Tool (01:04)
Oil your tools with one to three drops per day – any pneumatic tool oil will work.
Checking the Air Supply (01:35)
Using a 3/8-inch airline not longer than 25 feet, attach an air gauge to the back of your tool and connect the air supply to the gauge at approximately 100 psi. When actuating the tool, the pressure should drop to 90. Adding extra hose will cause the tool to drop to 80 psi when actuated.
Sanding Technique Basics (03:33)
Starting and stopping the tool - start the tool or actuate the tool while it is flat on the surface and stop it as you're lifting it from the surface. This will help minimize swirl marks or potential dipping when stopping the tool.
Using proper tool pressure - grip the tool firmly, but don't apply a lot of force or pressure. While running the tool, make sure it is not tipping to avoid dips in the surface or deeper scratches.
Recommended Sanding Pattern (04:28)
It's important to follow a very specific pattern. This is the north-south east-west pattern. Work on the surface front to back with overlapping passes. Overlap approximately half the pad to give even coverage. Then, begin working side to side on the panel.
