Greenlee 7309SB 11-Ton Hydraulic Knockout Kit Hand Pump, Slug-Buster 1/2 - 3, 4

Using the Greenlee 7309SB is straightforward. First, select the right punch and die for your conduit size. Then, attach them to the 746A ram and 767 hand pump unit. Insert the draw stud through the material you're working on and into the punch. Use the hand pump to apply pressure until the hole is punched. After use, make sure to clean the punches, dies, and draw studs to prevent rust and debris build - up. When storing, keep the kit in the provided carrying case to protect it from damage. Also, always check the alignment markings and laser markings for accurate and quick work. Avoid using the kit on materials that it's not designed for, as this may damage the components. If you encounter any cross - threading issues, use the draw studs with 'dog point' tips to correct it. And remember, since it's a hydraulic tool, don't over - pressurize the hand pump to ensure long - term durability.
