Product Troubleshooting
Troubleshooting an Atlas Copco Cobratt Jackhammer involves a systematic approach to identify and resolve any issues. Here’s a step-by-step guide to help you through the process:
### 1. **Initial Inspection**
– **Visual Check**: Examine the jackhammer for any visible damage or wear. Look for cracks, loose parts, or signs of oil leakage.
– **Check Connections**: Ensure that all air connections are secure and that there are no leaks in hoses or fittings.
### 2. **Power Supply**
– **Air Supply**: Verify that the air pressure is within the required range specified in the user manual. Insufficient pressure can lead to poor performance.
– **Air Quality**: Ensure that the air entering the jackhammer is clean and dry. Moisture or contaminants can cause operational problems.
### 3. **Operational Check**
– **Start the Jackhammer**: Ensure the tool starts and runs smoothly. Listen for any unusual noises that may indicate internal issues.
– **Performance Test**: Check if the jackhammer is delivering the expected impact force. If it’s underperforming, it may require further investigation.
### 4. **Component Inspection**
– **Piston and Cylinder**: Remove the front head and inspect the piston and cylinder for wear or damage. Look for scoring or scratches that may affect operation.
– **Valves**: Check the valves for proper operation. Malfunctioning valves can lead to poor performance or inability to maintain pressure.
– **Chisels and Bits**: Examine the chisels and bits for wear. Dull or damaged bits can reduce efficiency and require replacement.
### 5. **Lubrication**
– **Check Oil Levels**: Ensure that the lubrication system has sufficient oil. Low oil levels can lead to increased wear and eventual failure.
– **Clean Lubrication System**: If the lubrication system is clogged, clean it according to manufacturer guidelines.
### 6. **Check Controls**
– **Trigger and Throttle**: Inspect the trigger mechanism and throttle for proper functionality. Ensure they are not sticking or malfunctioning.
– **Safety Features**: Test the safety features to ensure they are functioning as designed.
### 7. **Testing After Repairs**
– After any repairs or replacements, test the jackhammer again under normal conditions to confirm that the problem has been resolved.
### 8. **Documentation and Maintenance**
– Keep a log of any issues found and actions taken. Regularly scheduled maintenance can prevent many problems before they occur.
### Troubleshooting Tips:
– Always refer to the specific user manual for your model for detailed troubleshooting guidance.
