Greenlee 745H-3 Punch Unit for 3 Conduit

Using the Greenlee 745H - 3 is straightforward. First, select the appropriate punch and die for your job. Place the conduit where you want to make a hole, then use the draw stud to secure the punch and die in place. Make sure the material is properly positioned before starting the punching process. When using it on stainless steel, keep in mind that it's rated for up to 10 - gauge material. For fiberglass and plastic, its abrasion - resistant design will ensure long - lasting performance. As for maintenance, after each use, clean the punches and dies to remove any debris. You can use a mild cleaning solution and a soft brush. Store the unit in a dry place to prevent rust and damage. If you notice any signs of wear on the cutting edge, it might be time to replace the punch to keep getting clean and accurate holes.
