Using the Klein SRS56037 Magnetic Wire Pulling System is a breeze. First, take the system out of the storage tube. Connect the swivel leader eyelet to the wire or mesh wire pulling grip of the cable you want to pull. Then, start guiding the leader - pull through the enclosed space, like behind walls or in ceiling voids. The innovative design helps it navigate around insulation and other obstacles. When you're done with the job, wind the heavy - duty nylon rope onto the spool and put it back in the storage tube for protection. As for maintenance, keep the nylon parts clean and check the swivel eyelet regularly for any signs of wear. Avoid pulling the rope with excessive force to prevent damage. If you notice any issues, have it inspected or repaired before using it again.
