Using the Greenlee K09 - SYNCRO Hand Crimping Tool is quite easy. First, select the appropriate die using the color - coded one - dial die selection wheel according to your connector size. Then, place the connector in the crimper. Extend the handles to the desired length for better leverage and lock them in place. Apply pressure to the handles, and the tool will crimp the connector. When you're done, check the engraved crimp groove to make sure the connection is proper. As for maintenance, keep the tool clean and dry. After long - term use, you may need to lubricate the moving parts to ensure smooth operation. Also, store it in a cool, dry place to prevent corrosion. Avoid using it on connectors that are out of its capacity range, as this may damage the tool and affect the crimp quality.
