Using the iTOOLco CS50 Five - Conduit Feeding Sheave is quite straightforward. First, place the sheave in the desired location for your cable installation. Then, guide the cable through the sheave's wheel. The needle bearing rollers will ensure a smooth pull, reducing the effort needed. When it comes to maintenance, keep the sheave clean and free from debris. Periodically check the phenolic resin wheel for any signs of wear. If you notice any issues, refer to the 6 - year warranty for support. Also, make sure not to overload the sheave beyond its capacity to avoid damaging the wheel or the bearings.
