Using the DeWalt DCE151B cable stripper is a breeze. First, pick the right bushing according to the cable size you're working with. You can easily change bushings thanks to the quick - release feature. Then, set the depth gauge if needed to ensure a consistent strip up to 4 inches. Turn on the tool using the variable - speed trigger, which also has a reverse function for better control. If you're working in a dark place, turn on the adjustable LED light. When the tool jams, the E - Clutch™ system helps you keep control. As for maintenance, after each use, clean the tool to remove any cable debris. Check the bushings regularly for wear and tear, and replace them if necessary. Store the tool in a dry place to prevent damage. Always use appropriate DEWALT, Greenlee®, or Ripley® bushings for the best performance.
