Using the Greenlee 727 Cable Cutter is easy. First, make sure the cable you're cutting is within the specified capacity. Place the cable between the cutting blades and apply pressure on the plastic - coated handles. The high - leverage design will help you make the cut with less effort. Remember, this is not an insulated tool, so don't use it on live electrical cables. For maintenance, keep the cutter clean and dry. After use, wipe it down to prevent dirt and debris from building up. Since it has a rust - resistant finish, it should last a long time, but if you notice any signs of wear on the cutting blades, it might be time to replace them or get it serviced.
