8. Tightening and loosening bolts
A hex. socket matching the bolt or nut must
fi
rst be selected. Then mount the socket on the
anvil, and grip the nut to be tightened with the hex. socket. Holding the tool in line with the
bolt, press the power switch to impact the nut for several seconds.
If the nut is only loosely
fi
tted to the bolt, the bolt may turn with the nut, therefore mistaking
proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench
before restarting impact, or manually tighten the bolt and nut to prevent them slipping.
