2. Installing the bit (Impact driver)
Always follow the following procedure to install driver bit. (Fig. 10)
(1) Pull the guide sleeve back.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original position.
CAUTION:
If the guide sleeve does not return to its original position, then the bit
is not installed properly.
3. Removing the bit (Impact driver)
Please do the opposite point on the method of installing bit.
4. Selecting the socket matched to the bolt (Impact wrench)
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.
5. Installing a socket (Impact wrench)
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. (Fig. 11)
6. Retaining ring type (Impact wrench)
(1) Align the square portions of the socket and the anvil with each other.
(2) Make sure to firmly install the socket by pushing it all the way into the
anvil.
(3) When removing the socket, pull it out of the anvil.
