When dealing with rock drill malfunctions, here are some important considerations:

　　1. Safety First

　　- Ensure all operators are away from the malfunction area, especially when checking electrical or hydraulic systems.

　　- Use appropriate personal protective equipment, such as safety glasses, gloves, and earplugs.

　　2. Power Off Operations

　　- Always cut off the power supply to the rock drill before performing any repairs to prevent electrical accidents.

　　- For equipment with an automatic restart feature, ensure this function is locked to prevent accidental startup during repairs.

　　3. Correct Diagnosis

　　- Utilize the rock drill’s fault diagnostic system (if available) to help pinpoint the problem.

　　- Avoid dismantling parts without a thorough understanding of the fault, as this could lead to further issues.

　　4. Tools and Equipment

　　- Use the correct tools and equipment for repairs to avoid causing additional damage with inappropriate tools.

　　- Ensure all tools and equipment meet safety standards.

　　5. Spare Parts Management

　　- Ensure an adequate inventory of spare parts for quick replacement of damaged components when needed.

　　- For critical components, consider using original or equivalent quality replacements.

　　6. Recording and Feedback

　　- Keep detailed records of the malfunction occurrence, diagnosis process, and measures taken. This information is crucial for future fault prevention and repair work.

　　- Provide feedback on the malfunctions to the manufacturer so they can understand the product’s performance and potential issues.

　　7. Training and Qualification

　　- Ensure personnel handling the malfunction have the necessary skills and qualifications through professional training.

　　- Regularly assess skills and provide updated training to ensure repair personnel's skills are up-to-date with the latest repair techniques.

　　8. Preventive Maintenance

　　- Implement a regular preventive maintenance plan to reduce the likelihood of malfunctions.

　　- Perform maintenance according to the equipment’s usage and the manufacturer’s recommendations.

　　By following these considerations, rock drill malfunctions can be addressed timely, effectively, and safely, while also reducing the risk of future malfunctions.
