Believe we all know, electric wrench is in the power supply or battery powered wrench, is a tool which is used to tighten the bolt. And according to the small make up to know, general electric wrench is mainly used in steel structure installation, the installation of steel structure high strength bolt. So what's the operating essentials: electric wrench set torque operation main points:)First the counterforce support and appropriate and fixed sleeve is installed on the host. )Electric wrench host, make the switch in the forward position anyway. )On the tighten the screws, socket set, at the same time, the reaction force on the lever, depend on the appropriate protection (Can be adjacent to each other to tighten the screws, or other appropriate as a fulcrum place)And downtime. )Will control instrument on 'control' the position of the dial to the zero torque, puts the 'choice' torque to the torque is the number of corresponding, such as 'choice' torque '' on the corresponding torque values about N · m (kg·m), '' on' fine-tuning 'torque corresponding torque values for N · m (kg·m)。 )Start the host fastening, when automatic stop, namely has reached a predetermined torque value, tighten the finish. Fixed Angle of operating points:)Will set Jane set on by tighten the screws, and start the host, made the arm close to pivot after downtime. )Will control instrument on 'control' to 'corner' position, the Angle of 'choice' dial to a predetermined Angle value. )Start the host fastening, automatic stop when, that is, at a predetermined Angle value. Constant torque Angle of continuous operation points:)The sleeve set on the screw thread parts, start the host, made the lever by tight protection after downtime. )To control instrument on 'control' to 'torque Angle' position. Put 'torque choice' and '' are selected respectively to predetermined torque is the number of corresponding and achieve the value after a predetermined Angle. )Start the host, when the torque to the expected value, the torque control is automatically changed to Angle control, when the Angle to the expected value, namely, automatic stop.
