1. Operation 1 Operating the air shear 2 Cutting metal and plastic This Air Shear is designed to operate on 90 PSIG Lower pressure below 90 PSIG will reduce performance of the tool Higher air pressure over 90 PSIG raises the The air shear is suitable for cutting metals and plastics up performance of the tool beyond its rated capacity and to 16 gauge could cause serious damage to the tool and the user Hold the air shear with one hand on the handle Place the open shear blades on the work surface To start cutting press the trigger lightly and then increase the trigger pressure to achieve the desired cutting speed
