To make the best possible cut:  Clamp the workpiece firmly and cut close to the clamping point to eliminate any vibration of the work. Cut the workpiece using the peripheral edge of the cutting wheel. When cutting conduit pipe or angle iron, clamp the workpiece in a vise if possible and cut close to the vise. To cut thin sheet material, "sandwich" the material between hardboard or plywood and clamp the layers to eliminate vibration and material tearing. DANGER: Never use the tool with the guard removed. It has been designed for use only with the guard and guard insert installed. Attempting to use tool with guard removed will result in loose particles being thrown against the operator resulting in serious personal injury.  Remove the battery pack.  Install cutting wheel and wheel guard with guard insert.  Install the battery pack.  Hold the tool in front and away from you with both hands, keeping the cutting wheel clear of the workpiece.  Turn the tool ON and let the motor and cutting wheel build up to full speed.  Move the cutting wheel into the workpiece. NOTE: Do not force. Use only enough pressure to keep the tool cutting. Let the wheel and tool do the work. 11 - English
