Prior To Operation - Hitachi WH 8D2 Instruction Manual And Safety Instructions

!
CAUTION:
When the battery charger has been continuously used, the battery charger will
be heated, thus constituting the cause of failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
If the battery is recharged when it is warm due to battery use or exposure to
sunlight, the pilot lamp may not light. The battery will not be recharged. In such
a case, let the battery cool before charging.
If the pilot lamp blinks quickly (at 0.2-second intervals), check for and take out
any foreign objects in the charger's battery installation hole.
If there are no foreign objects, it is probable that the battery or charger is
malfunctioning. Bring them to HITACHI AUTHORIZED SERVICE CENTER.

PRIOR TO OPERATION

1. Confirm that the battery is mounted correctly
2. Selecting the socket to be matched to the bolt
Be sure to use a socket which is matched to the bolt to be tightened. Using an
improper socket will result not only in insufficient tightening but also in damage
to the socket or nut.
A worn or deformed hex or suqare-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 in Tables 2 and 3.
The numerical value of a socket designation denotes the side-to-side distance (H)
of its hex hole.
3. Mounting the socket (Fig. 12)
Align the plunger loated in the square
part of the anvil with the hole in the hex.
socket and mount the hex. socket on the
anvil. Check that the plunger is fully en-
gaged in the hole.
