Regular maintenance ensures the longevity and safe operation of your tool.

• Cleaning: After each use, clean the tool's ventilation slots and housing with a soft brush or compressed air. Do not use water or chemical cleaning agents.
• Chuck Maintenance: Keep the chuck clean and free of dust and debris. Apply a small amount of grease to the SDS-Plus bit shanks before insertion to reduce wear.
