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.
CAUTION:
●
Please use the designated attachments which are listed in the operations manual and Hitachi's catalog.
Accidents or injuries could result from not doing so.
●
Make sure to firmly install the socket in the anvil. If the socket is not firmly installed it might come out and
cause injuries.
7. Confirm that the battery is mounted correctly
8. 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. 12)
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.
9. 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.
10. Change rotation speed
As shown in Fig.13, when the rotation switch-over lever is slid to the
lower side, the power mode (P) is set. And when slid to upper side, the
save mode (S) is set.
Please use the save mode (S) when you want to lower Maximum
tightening torque.
