Using this Milwaukee fish tape kit is a breeze. First, make sure your M18™ REDLITHIUM™ batteries are fully charged using the multi - voltage charger. Attach the desired drum to the powered base using the quick - change latches. Then, use the variable speed trigger to control the movement of the fish tape. When you're done, the tape will automatically retract into the drum, keeping your workspace tidy. For safety, always wear appropriate protective gear. Don't overload the machine; the REDLINK PLUS™ Intelligence helps with that, but it's still important to be cautious. When it comes to maintenance, regularly check the drums for any signs of wear and tear. You can replace the drums easily if needed. Keep the powered base clean and store it in a dry place when not in use. This way, your Milwaukee fish tape kit will serve you well for a long time.
