Operator's Manual. The Greenlee 7506 knockout punch kit is a must - have for construction and maintenance tasks. Its conduit sizes are based on the outside diameter of US conduit sizes. For instance, a 1/2' conduit size punch creates a 7/8' hole. It comes with 1/2' - 2' Conduit Size Slug - Splitter SC (Self Centering) knockout punches. These punches can handle up to 10 gauge (3.5 mm) stainless steel. The self - centering feature aligns the punch on the pilot hole, eliminating the need for crosshairs or die alignment marks. It's incredibly fast, easy, and simple to operate. Its compact design makes it ideal for on - site use. Additionally, it can drive a 751 Cable Cutter head. The kit includes a powerful 11 - ton hydraulic ram and a 3 - foot hose, along with a hand pump.
Using the Greenlee 7506 knockout punch kit is a breeze. First, select the right punch size according to your conduit needs. The self - centering feature will help you align the punch on the pilot hole automatically, so you don't have to waste time with alignment marks. Then, use the hand pump to operate the 11 - ton hydraulic ram. This will drive the punch through the material. Remember, this kit can handle up to 10 gauge (3.5 mm) stainless steel, so don't try to use it on thicker materials. When you're done, clean the punches and the hydraulic ram with a dry cloth. Keep the kit in a dry place to prevent rust. Also, check the 3 - foot hose regularly for any signs of damage. If you need to use the 751 Cable Cutter head, simply attach it to the kit and follow the same operation steps.
