1, the power supply voltage should be preceded view is consistent with the product nameplate, whether grounding device. When the supply voltage exceeds + 10% voltage steps should be taken, otherwise it will affect the control accuracy. Bad ground easily cause an accident. 2, ambient temperature the tools used for -10 ℃ -40 ℃, too low will affect the control accuracy. 3. Tighten the bolts are not greater than the initial torque tools, 70% of the rated torque. After the rated torque is not heavy bolt screwed. 4. Remove the bolt when the tool is used, the torque is not greater than the rated torque value. Under normal circumstances, this is not a wrench to tighten a bolt or severe corrosion, should not use this wrench to remove the domestic fixed-torque electric wrench to avoid tool damage. 5, when changing the direction of rotation must be carried out until the motor stops after forbidden reverse toggle switch in the operation. 6, when the wrench to loosen the automatic stop switch (if constantly open switch, over five seconds wrench will start their own) to be 4-5 seconds before conducting the start wrench, wrench otherwise not start. Electric torsional shear torsional shear wrench the name suggests is a Torx bolt tightening operations necessary tool joint torque electric wrench set, help you install, demolition bolts, nuts, and can more accurately control the tightening torque. Fixed by bolts torque wrench when a certain torque to cut part Torx bolts of torque accuracy and axial tension is given by V-shaped incision torque bolts to guarantee. Disassembly twisting torque, more reliable than hand-insurance. Convenient, beautiful, practical, easy to bring with him. Widely used in construction work steel bridges, factories, power plants and other facilities. Electric wrench features: (1) long life (2) handles and cabinet materials, good heat dissipation (3) power (4) impact-resistant and strong (5) hand using the highest cost electric torsional shear wrench is a tight end torsional shear strength bolts tools, general electric torsional shear wrench and manual wrench torsional shear, which is more common electric torsional shear wrench. Torsional shear wrench applications: torsional shear type high strength bolts tight early electric impact wrench can be used or given electric torque wrench set torque wrench, but you must use the tight end wrench torsional shear, torsional shear wrench is designed so tight end torsional shear type high strength bolts a. Torsional shear wrench Use: mainly torsional shear wrench tight end torsional shear type high strength bolts, and its purpose is to torsional shear type high strength bolts Torx be interrupted. Work will be aligned with the bolt head wrench head imported electric torque wrench set, pull the switch to start the work, after a few seconds, Torx bolts will be broken, and then out of the Torx wrench to pull the trigger pop-up, that the end of the work. Torsional shear wrench features: easy to operate, time-saving, safe and convenient electric torque wrench set manufacturers | set torque electric wrench | in General Technology provided by Jinan Cape Technology Limited. Jinan Cape Technology Co. (www.jnddbs.cn) strong, credible, and other industries in other Jinan accumulated a large number of loyal customers.
