General Power Tools Safety Warnings

• Working Area: Keep your working area clean and well-lit. Untidy and dark areas can lead to accidents. Do not operate power tools in potentially explosive surroundings, for example, in the presence of inflammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
