Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. To clean thoroughly, some parts may need to be removed. For optimum performance from your machine, make sure you clean all moving parts or sliding contact surfaces that are coated.

SECTION 4: OPERATIONS General Disc Sanding This section covers basic sanding operations. Please read the remaining portion of the manual before attempting any type of operation. Always keep the workpiece on the side of the wheel that is rotating down toward the table. This will keep the workpiece from flying out of your hands due to the rotational forces.
PAGE 20
Miter Sanding Angle Sanding The most efficient way to get a perfect miter is to cut the workpiece slightly long and sand it to the desired dimension. Miter sanding can be done easily with the miter gauge. Always keep the workpiece on the side of the wheel that is rotating down toward the table. This will keep the workpiece from flying out of your hands from the rotational forces. To perform miter sanding operations: 1.

Belt Sanding Belt sanding allows you to sand the flat surface of a workpiece. To perform belt sanding operations: 1. Turn the power ON and allow the sander to reach full speed. 2. Place the workpiece against the surface of the sanding belt. Hold the workpiece firmly with both hands but keep fingers away from the sanding surface as shown in Figure 14. 3. Move the workpiece across the surface of the belt for even belt wear. 4.
