Using the Greenlee E12CCXLX11 is a breeze. First, make sure the battery is fully charged or connect the charger if you're using the corded option. Then, select the right die for your crimping or cutting job. Place the wire or connector in the tool, and press the trigger. The tool will do the rest, and it'll retract automatically when the cycle is done. Remember to check the LED display for pressure and battery levels. As for maintenance, keep the tool clean and dry. Use the biodegradable oil as recommended. If the LED light shows maintenance is needed, follow the instructions in the Gator Eye app. Also, store the tool in a cool, dry place when not in use. When handling the batteries, always use the smart charger to ensure long battery life.
