OPERATION OPERATING THE SANDER See Figure 6.  Secure the workpiece to prevent it from moving during operation. WARNING: Unsecured workpieces could be thrown towards the operator causing injury. WARNING: Keep your head away from the sander and the sanding area. Your hair could be drawn into the sander, causing serious injury.  Place the sander on the workpiece so that all of the sanding disc surface is in contact with the workpiece. CAUTION: To avoid motor damage resulting from overheating, do not cover the air vents with your hand.  Turn on the sander and move it slowly over the workpiece. Make successive passes in parallel lines, circles, or crosswise movements.  Turn off the sander and wait until the sanding disc comes to a complete stop before removing it from the workpiece. Do not force. The weight of the sander supplies adequate pressure to do the work. Applying additional pressure only slows the motor, rapidly wears the sanding sheet, and greatly reduces sander speed. Excessive pressure will overload the motor causing possible damage from overheating and can result in inferior work. Any finish or resin on wood may soften from the frictional heat. Do not sand on one spot too long as the sander's rapid action may remove too much material, making the surface uneven. Extended periods of sanding may overheat the motor. If this occurs, turn the sander off and wait until the sanding sheet comes to a complete stop. Remove sander from workpiece. Remove sanding disc, then turn sander on and run it free without a load to cool the motor. 13 Fig. 6
