Sanding operation
Hold the tool firmly with both hands. Turn the tool on and wait until it attains full speed.
Then gently place the tool on the workpiece surface. Keep the belt flush with the work-
piece at all times and move the tool back and forth. Never force the tool. The weight of the
tool applies adequate pressure. Excessive pressure may cause stalling, overheating of the
motor, burning of the workpiece and possible kickback.
