Preparation Before Cleaning

  1. Ensure the drill is turned off and remove the battery to prevent accidental activation.
  2. Gather cleaning tools such as a soft brush, compressed air, and a damp cloth.
  3. Work in a well-ventilated area, preferably on a stable surface.

Cleaning the Exterior

  1. Use a dry, soft brush to gently remove dust and debris from vents, switches, and the body.
  2. Damp a cloth with water or a mild cleaner, then wipe the exterior surfaces. Avoid excess moisture.
  3. Use compressed air to blow out dust from vents and crevices, holding the can upright to prevent propellant spray.

  3. If needed, lightly dampen a cloth and wipe the chuck area. Do not soak.

Do not open the drill casing yourself; instead, use compressed air to blow out dust from accessible vents. If your drill exhibits performance issues, consult a professional technician for internal cleaning or repairs.

Final Checks and Reassembly

Ensure all parts are dry before reinserting the battery. Check for any visible damage or loose parts. Store the drill in a clean, dry place to prevent future buildup.
