rotating will result in burning the motor.
2. 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. Hold-
ing 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 with

nut and hold the bolt head with a wrench before restarting impact, or manually
tighten the bolt and nut to prevent them slipping.
