Operation OPERATION (CONTINUED): 5. Selecting the socket matched to the bolt: a. Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will not only result in insufficient tightening but also in damage to the socket or nut. b. A worn or deformed hex or square-holed socket will not give an adequate tightness for fitting to the nut or anvil, consequently resulting in loss of tightening torque. (Fig. 13) c. Pay attention to wear

Operation OPERATION (CONTINUED): 11. Tightening and loosening bolts: A hex socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds. If the nut is only loosely fitted to the bolt, the bolt may turn wit the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and ho
