Using the iTOOLco CS60 Conduit Feeding Sheave is a breeze. First, make sure you have the proper setup for your electrical installation. Place the sheave where you need it along the conduit path. When you start pulling the wire, the needle - bearing rollers will work their magic, smoothly guiding the wire and reducing drag. Just be careful not to overload the sheave beyond its capacity as it may affect its performance. As for maintenance, keep it clean from dirt and debris regularly. Check the bearings and the phenolic resin wheel for any signs of wear. If you notice any issues, don't worry, as it comes with a 6 - year warranty, so you can get it fixed or replaced.
