Using the Jet 220025 rebar cutter and bender is straightforward. First, mount it on a board or floor to enable one - handed operation. Then, place the up - to 5/8 inch grade 60 rebar into the jaws. The needle bearing design makes it easier to start the cutting or bending process. When using, make sure the rebar's hardness does not exceed HRC - 48. For safety, keep your hands away from the moving parts. After each use, clean the tool to remove any debris. Regularly check the jaws and the needle bearing for wear and tear. If any part shows significant damage, replace it immediately to ensure the tool's long - term performance.
