2. General Safety Instructions
Always follow basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury.
2.1 Work Area Safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.2 Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way.
- Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
2.3 Personal Safety
- Always wear eye protection. Safety glasses or goggles are essential.
- Wear appropriate personal protective equipment (PPE) such as dust masks, non-skid safety shoes, hard hats, or hearing protection when necessary.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
- Stay alert, watch what you are doing, and use common sense when operating a power tool.
- Do not overreach. Keep proper footing and balance at all times.
2.4 Angle Grinder Specific Safety
- Always ensure the guard is correctly positioned and securely fastened before operation.
- Use only grinding wheels and accessories that are rated for the speed of the grinder and are in good condition.
- Never force the tool. Allow the grinder to reach full speed before applying it to the workpiece.
- Be aware of kickback. Kickback is a sudden reaction to a pinched or snagged rotating wheel. Always maintain a firm grip on the tool.
- Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool.
