  • Only use tools that are marked with the official international 1,000-volt rating symbol shown above, if there is any chance that the tools will make contact with a live electrical source.
  • Whenever possible, always switch off lines and equipment prior to working on or around them. Klein insulated tools are designed only to reduce the chance of injury where the tool may make contact with a live source.
  • Do NOT touch uninsulated portion of the tool or any conductive object when either might contact a live electrical source.
  • Wear approved eye protection.
  • Because moisture, films or other surface contaminants are conductive, Klein insulated tools must be kept clean, dry and free from any surface contaminants.
  • Always inspect your tools before use. Destroy tool if insulation becomes damaged in any way.
