GENERAL OPERATIONAL PRECAUTIONS
1.Keep work area clean. Cluttered areas and benches invite injuries.
2.Consider work area environment. Don’t expose power tools to rain. Don’t use power tools in damp or wet locations. Keep work area well lit. Don’t use tool in presence of flammable liquids or gases.
Power tools produce sparks during operation. They also spark when switching ON/OFF. Never use power tools in dangerous sites containing lacquer, paint, benzine, thinner, gasoline, gases, adhesive agents, and other materials which are combustible or explosive.
3.Guard against electric shock. Prevent body contact with grounded surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
4.Keep children away. Do not let visitors contact tool or extension cord. All visitors should be kept away from work area.
5.Store idle tools. When not in use, tools should be stored in dry and high or locked-up place-out of reach of children.
6.Don’t force tool. It will do the job better and safer at the rate for which it was intended.
7.Use right tool. Don’t force small tool or attachment to do the job of a heavy-duty tool. Don’t use tool for purpose not intended —for example —don’t use circular saw for cutting tree limbs or logs.

18.Stay alert. Watch what you are doing. Use common sense. Do not operate tool when you are tired.
19.Check damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated else where in this handling instructions.
