2. Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury. This section outlines general safety guidelines for power tools and specific precautions for hammer drills.

2.1 General Power Tool Safety

• Work Area Safety: Keep your 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.
• 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.
• Personal Safety: Always wear eye protection. Use hearing protection when operating noisy tools. Wear a dust mask if operations create dust. Dress properly; avoid loose clothing or jewelry that can get caught in moving parts.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.

2.2 Specific Hammer Drill Safety

• Hold Tool Firmly: Always hold the tool firmly with both hands to maintain control, especially during hammer drilling or chiseling.
• Secure Workpiece: Ensure the workpiece is stable and securely clamped to prevent movement during operation.
• Check for Hidden Utilities: Before drilling into walls, floors, or ceilings, check for hidden electrical wires, gas pipes, or water pipes using a suitable detector.
• Dust Management: Drilling and chiseling can generate significant dust. Use a dust guard and wear a dust mask to protect your respiratory system.
• Overheating: Allow the tool to cool down during prolonged use to prevent overheating.
