Safety measures and precautions

  1. Personal Protective Equipment (PPE):
    • Eye Protection: Wear safety glasses or a face shield to protect your eyes from dust, debris, and potential flying particles.
    • Ear Protection: If the rotary hammer generates a high level of noise, use earplugs or earmuffs to protect your hearing.
    • Respiratory Protection: If working in a dusty environment, use a dust mask or respirator to prevent inhalation of airborne particles.
  2. Clothing:
    • Wear appropriate work attire, including long sleeves, pants, and steel-toed boots to protect against potential injuries from falling debris or accidental contact with the tool.
  3. Work Area Safety:
    • Ensure the work area is well-lit to enhance visibility.
    • Keep the work area clean and free of clutter to prevent tripping hazards.
    • Mark and secure any potential tripping hazards, such as cords or hoses.
  4. Tool Inspection:
    • Before use, inspect the rotary hammer and the SDS steel set for any damage or defects. Do not use damaged tools or accessories.
    • Ensure that the drill bits or chisels are securely attached to the SDS chuck.
  5. Secure Workpiece:
    • Secure the workpiece properly to prevent movement or slippage during drilling or chiseling.
    • Use clamps or other appropriate methods to secure the material in place.
  6. Proper Tool Handling:
    • Hold the rotary hammer with both hands and maintain a firm grip during operation.
    • Do not override the tool’s capacity. Follow the manufacturer’s guidelines regarding the maximum drilling or chiseling capacities.
  7. Correct Tool for the Task:
    • Use the appropriate SDS steel attachment for the specific task at hand.
    • Avoid using excessive force, and let the tool work at its own pace.
  8. Power Source Safety:
    • When using a corded rotary hammer, make sure the power cord is in good condition and properly grounded.
    • If using a cordless rotary hammer, ensure that the battery is fully charged.
  9. Switch Off When Not in Use:
    • Always switch off the rotary hammer and disconnect it from the power source when changing drill bits or when the tool is not in use.
  10. Training and Familiarity:
    • Only trained and authorized personnel should operate the rotary hammer.
    • Familiarize yourself with the tool’s user manual and follow the manufacturer’s instructions.
