Before Use; Operation - Hitachi WR 18DBDL2 Instruction Manual

English
● When the pilot lamp fl ikers rapidly in red (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. Take it to your authorized
Service Center.

BEFORE USE

Check the work area to make sure that it is clear of debris
and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.

OPERATION

1. 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 insuffi cient 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 fi tting 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.
2. Installing a socket
Select the socket to be used.
● Pin, O-ring type
(1) Slide the O-ring out of the groove, then align the hole
of the socket with the hole of the anvil and insert the
anvil into the socket.

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 fi rmly install the socket in the anvil.
If the socket is not fi rmly installed it might come
out and cause injuries.
● When sliding the O-ring out of the groove of the
socket, be careful not to drop and lose the pin.
● It is possible to temporarily hold the socket in
place with the friction ring, but be sure to insert
the pin and attach the O-ring before use.
If the power tool is used while the socket is
temporarily held in place, the socket may fall off
and cause an injury.
3. Confi rm that the battery is mounted correctly.
4. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the pushing button.
The L-side of the pushing button is pushed to turn the
bit counterclockwise. (See Fig. 11). (The
marks are engraved on the body.)
