on housing, the other on side handle). Start the tool and
bring the grinding wheel on the workpiece.
• Keep the edge of the wheel tilted at angle from 15 to 30
degrees against the surface of the workpiece.

wheel in the B direction, otherwise, it will cut into the
workpiece. When the edge of wheel has been rounded off,
you are free to operate the grinder in either the A or B
direction.
