2. Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury when using power tools. Read all instructions carefully before operation.

  • Wear Personal Protective Equipment (PPE): Always wear safety glasses, gloves, and hearing protection. A dust mask is recommended for dusty operations.
  • 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: Avoid body contact with earthed or grounded surfaces (e.g., pipes, radiators, ranges, refrigerators). Do not expose power tools to rain or wet conditions.
  • Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
  • Maintain Tools: Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.
  • Battery Pack Use and Care: Recharge only with the charger specified by the manufacturer. Do not use battery packs with any other power tools.
  • Dust-Proof Technology: This angle grinder features magnets near the housing to prevent small iron filings from entering the motor and an air intake design to block larger metal chips, enhancing motor protection and tool longevity.
