Using the Greenlee EK1550FLX11 is easy. First, make sure the battery is fully charged. You can check the battery status on the LED display. Insert the wire and connector into the crimping head, then press the trigger. The tool will start the crimping process automatically and retract when it's done. For safety, always use the correct wire size and connector type as specified in the product. When not in use, store the tool in a dry place. To maintain the tool, clean the crimping head regularly and check the battery health. If you notice any abnormal noises or the crimping force is not right, use the Gator Eye app to check the tool diagnostics. This will help you keep the tool in good condition and ensure efficient crimping.
