6.When drilling metal, always use a punch to mark the drilling position. Use a lubricant with most metals, to prolong the life of the bit and increase the drilling action . With steel, tin, and sheet metal use a light machine oil, with aluminum, use paraffin. Do not use lubricants with brass, copper, and cast iron. Grasp the drill firmly with both hands and slowly squeeze the Trigger (3). Never force the tool. Only apply light pressure when horizontal drilling.

7.When driving screws, use bits suitable for the type and size of screw you are using. Drill a pilot hole for the screw head to bite into. Use the lowest torque setting.
