CAUTION:
If the tool falls, there is a risk that malfunction and/or physical damage can occur. It is recommended that you
also use fall-preventing wires, etc.
Incomplete installation of the hook E may result in bodily injury when used.
(a) Securely hold the main unit and remove the screw using a slotted head screwdriver or a coin. (Fig. 6)
(b) Remove the hook and spring F. (Fig. 7)
(c) Install the hook E and spring F on the other side and securely fasten with screw. (Fig. 6)
NOTE: Pay attention to the spring F orientation. Install the spring F with larger diameter G away from you. (Fig. 8)
1.2 Using as an auxiliary light
(1) Press the switch H to turn off the light.
If forgotten, the light will turn off automatically after 15 minutes.
(2) The direction of the light can be adjusted within the range of hook positions 1 – 5. (Fig. 9)
Lighting time
AAAA manganese batteries: approx. 15 hrs.
AAAA alkali batteries: approx. 30 hrs.
CAUTION:
Do not look directly into the light. Such actions could result in eye injury.

1.3 Replacing the batteries

(1) Loosen the hook screw J with a Phillips-head screwdriver (No. 1) I. (Fig. 10)
Remove the hook cover L by pushing in the direction of the arrow. (Fig. 11)
(2) Remove the old batteries and insert the new batteries. Align with the hook indications and position the plus (+)
and minus (–) terminals correctly. (Fig. 12)
(3) Align the indentation in the hook E main body with the protuberance of the hook cover L, press the hook
cover L in the direction opposite to that of the arrow K shown in Fig. 11 and then tighten the screw.
Use commercially available AAAA batteries (1.5 V) O.
NOTE: Do not tighten the screw excessively. Such action could strip the screw threads.
CAUTION:
Failure to observe the following can result in battery leakage, rust or malfunction.
Position the plus (+) and minus (–) terminals correctly.
Replace both batteries at the same time. Do not mix old and new batteries.
Remove exhausted batteries from the hook immediately.
Do not discard batteries together with normal trash and do not throw batteries into fire.
Store batteries out of the reach of children.
Use batteries correctly in accordance with the battery specifications and indications.
2. Installing the bit (Impact driver)
Always follow the following procedure to install driver bit. (Fig. 2)
(1) Pull the guide sleeve 7 back.
(2) Insert the bit 9 into the hexagonal hole in the anvil 8.
(3) Release the guide sleeve 7 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 B with the hole in the hex. socket 0. Then push the
plunger, and mount the hex. socket 0 on the anvil B. Check that the plunger is fully engaged in the hole.
When removing the socket 0, reverse the sequence.
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.
