CAUTION:
Always wear safety goggles or a face shield during

operation.
Never run the tool without the abrasive disc. You
•
may seriously damage the pad.
Hold the tool firmly with one hand on the gripping part of
the tool and the other hand on the side grip when
performing the tool. Turn the tool on and then apply the
abrasive disc to the workpiece.
In general, keep the abrasive disc at an angle of about
15 degrees to the workpiece surface. Apply slight
pressure only. Excessive pressure will result in poor
performance and premature wear to abrasive disc.
