Safety

  • Do not direct the light beam at persons or animals and do not stare into the light beam yourself.
  • Do not cover the lamp head while the work light is in operation, as it generates intense heat.
  • Remove the battery before any work on the work light (e.g., maintenance) and during transport or storage.
  • Do not allow children to use the work light.
  • Protect the battery against heat, continuous intense sunlight, fire, water, and moisture.

Maintenance and Cleaning

The work light is maintenance-free and contains no components that require replacement or maintenance. The light source cannot be replaced; if it is defective, the entire work light must be replaced. Clean the plastic lens only with a dry, soft cloth to avoid damage. Do not use cleaning agents or solvents.
