- Do not exceed the maximum rotational speed recommended for your lathe chuck and drill.
- Keep hands and loose clothing away from rotating parts.
- Inspect the connecting rod for any signs of wear, damage, or deformation before each use. Do not use if damaged.
5. Setup
Follow these steps to properly set up the connecting rod with your lathe chuck and drill/motor:
- Prepare the Lathe Chuck: Ensure your K01-50/63 or K02-50/63 lathe chuck is clean and free from debris.
- Attach to Chuck: Carefully thread the M14*1 end of the connecting rod into the corresponding thread on your lathe chuck. Tighten securely using an appropriate wrench, ensuring there is no play.
- Prepare the Drill/Motor: Insert the 10mm shank end of the connecting rod into the chuck of your electric drill or motor. Ensure the shank is fully seated and centered.
- Secure the Drill Chuck: Tighten the drill chuck securely around the 10mm shank. Verify that the connecting rod is held firmly and does not wobble.
- Final Check: Manually rotate the assembly to confirm smooth movement and proper alignment before powering on the equipment.

6. Operating Instructions
Once the connecting rod is securely installed, you can proceed with your machining tasks. Always operate the equipment within its intended parameters.
- Start the drill/motor at a low speed and gradually increase to the desired operating speed.
- Monitor for any unusual vibrations, noises, or excessive heat during operation. If detected, immediately stop the machine and inspect the setup.
- Ensure the workpiece is properly secured in the lathe chuck before beginning any cutting or shaping operations.
- Avoid applying excessive force that could strain the connecting rod or the chuck.
- When finished, gradually reduce the speed and turn off the drill/motor. Allow all rotating parts to come to a complete stop before touching the assembly.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your connecting rod.
- Cleaning: After each use, clean the connecting rod to remove any metal shavings, dust, or lubricants. Use a clean cloth and a mild cleaning agent if necessary.
- Inspection: Periodically inspect the threads (M14*1) and the shank (10mm) for wear, damage, or corrosion. Check for any cracks or deformities in the stainless steel body.
- Lubrication: Apply a thin layer of machine oil to the threads and shank if storing for extended periods to prevent rust.
- Storage: Store the connecting rod in a dry, clean environment, protected from moisture and impact.
8. Troubleshooting
If you encounter issues during the use of your connecting rod, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive Vibration | Loose connection, bent rod, unbalanced chuck/workpiece. | Ensure all connections are tight. Inspect rod for damage. Re-balance chuck or workpiece. |
| Rod does not fit chuck/drill | Incorrect size or thread type. | Verify compatibility (M14*1 thread for chuck, 10mm shank for drill). Ensure correct product variant was purchased. |
| Difficulty threading | Damaged threads, debris in threads. | Clean threads on both rod and chuck. Inspect for cross-threading or damage. Do not force. |
