4.2 Sanding Techniques

Proper technique ensures efficient sanding and a smooth finish.

• Always hold the sander firmly with both hands using the main grip and auxiliary handle (1).
• Start the sander before placing it on the workpiece.
• Apply light, even pressure. Let the sander do the work. Excessive pressure can slow the motor, damage the belt, and produce an uneven finish.
• Move the sander smoothly and continuously over the surface in the direction of the wood grain. Avoid stopping in one spot, as this can create depressions.
• For rough sanding, use a coarser grit belt (e.g., 80 grit included). For finer finishes, progress to higher grit belts.
