Using the Greenlee FTXS-125BP fish tape is a straightforward process. First, place the case on the ground to free up both your hands. Then, start pulling out the tape for fishing, cable installation, or cable pulling. The free-spinning interior reel will make the process faster. When you're done, use the storage lock to keep the tape secure during transport. As for maintenance, regularly open the easy-open case to clean the tape and check the reel cartridge. If the tape gets damaged, you can easily replace it with a quick-change reel. Remember, the tape has a tensile strength of 400 lbs, so don't exceed this limit to avoid breakage. Also, keep it in a dry place to prevent rusting of the steel tape.
