General Safety Instructions
Always observe basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury. Keep this manual handy for quick reference.
- 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. Do not use any adapter plugs with earthed (grounded) power tools. Avoid body contact with earthed or grounded surfaces.
- Personal Safety: Always wear eye protection. Use hearing protection when operating the tool for extended periods. Wear a dust mask if working in dusty conditions. Dress properly; avoid loose clothing or jewelry.
- 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.
- Safety Clutch: The hammer is equipped with a safety clutch that protects the user in case of drill bit jamming. This feature helps prevent kickback.
- Anti-Vibration System (AHV): The AHV system minimizes vibrations, but prolonged use still requires breaks to prevent fatigue.
