Operating the Machine
Make sure there is a good flow of water.
Always keep the disc flat of the surface being sanded – never work the disc on its edge.
We recommend that you learn how to use the machine by starting with an Acrylic sanding 100# disc which will not cause any significant damage while you get used to keeping the disc flat on the surface being sanded.
Use the shoulder strap, properly adjusted, to take the weight of the sander. Hold the machine close to your body and “lock” your arms and the machine together, move the sanding head by swaying your body from the hips rather than swinging the machine with your arms like you would do with most dry sanders. This is essential in helping to keep the disc flat on the surface.
Use a sweeping motion swaying your hips to help keep the disc flat – do not “nibble” at the surface like when using an orbital sander.
Do not push hard on the surface being sanded – let the disc do the work.
All painted surfaces are different. You will need to experiment with different discs to see which ones work best.
