6. Maintenance

• Cleaning: Wipe all tools with a clean, dry cloth after each use to remove dirt, dust, and debris. For stubborn grime, a slightly damp cloth can be used, followed by immediate drying.
• Storage: Always return tools and accessories to their designated slots in the compact case after use. Ensure the case is securely latched to prevent items from falling out or getting lost. Store the case in a dry, cool place away from direct sunlight and moisture.
• Electric Screwdriver Battery Care: To prolong battery life, avoid fully discharging the screwdriver frequently. Recharge the battery when the power indicator is low. If storing for an extended period, charge the battery to approximately 50-70% every 3-6 months.
• Bit Inspection: Periodically inspect screwdriver bits for wear or damage. Replace worn bits to maintain optimal performance and prevent stripping screws.
