2. Selecting the socket matched to the bolt
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.
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.
Pay attention to wear of socket hole, and replace
before further wear has developed.
Matching socket and bolt sizes are shown Tables
4, 5, 6 and 7. The numerical value of a socket
designation denotes the side-to-side distance (H)
of its hex. hole.
3. Installing a socket (Fig. 9, 10)
Align the plunger located in the square part of the
anvil with the hole in the hex. socket. Then push
the plunger, and mount the hex. socket on the
anvil. Check that the plunger is fully engaged in
the hole. When removing the socket, reverse the
sequence.
4. Removing the socket
Please do the opposite point on the method of
installing socket.
5. Confirm that the battery is mounted correctly.
6. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the push button.
The L-side of the push button is pushed to turn
the bit counterclockwise. (See Fig. 11) (The
and
R
marks are engraved on the body.)
CAUTION
The push button can not be switched while the impact driver is turning. To switch the
push button, stop the impact driver, then set the push button.
7. Switch operation
When the trigger switch is depressed, the tool rotates. When the trigger is released, the
tool stops.
The rotational speed can be controlled by varying the amount that the trigger switch is
pulled. Speed is low when the trigger switch is pulled slightly and increases as the
trigger switch is pulled more.
NOTE
A buzzing noise is produced when the motor is about to rotate; this is only a noise, not
a machine failure.
