CAUTION
○
Applying the impact driver for too long tightens the screw too much and can break it.
○
Tightening a screw with the impact driver at an angle to that screw can damage the
head of the screw and the proper force will not be transmitted to the screw. Tighten
with this impact driver lined up straight with the screw.
7. 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.
