Prior To Operation; How To Use - Hitachi WH 14DBDL Handling Instructions Manual

English
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a while.
CAUTION
When the battery charger has been continuosly used,
the battery charger will be heated, thus constituting
the cause of the 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
map light in green.
The battery will not be recharged. In such a case, let
the battery cool before charging.
When the pilot lamp flickers 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.

PRIOR TO OPERATION

1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at
all loose it could come off and cause an accident.
3. Installing the bit (WH14DBDL / WH18DBDL)
Always follow the following procedure to install driver
bit. (Fig. 5)
(1) Pull the guide sleeve away from front of the tool.
(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.
4. Selecting the socket matched to the bolt
(WR14DBDL / WR18DBDL)
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 (WR14DBDL / WR18DBDL)
Select the socket to be used.
Pin, O-ring type
(1) Align the hole in the socket with the hole in the anvil
and insert the anvil into the socket.
(2) Insert the pin into the socket.
(3) Attach the ring to the groove on the socket.
Plunger type
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.
11
Retaining ring type
(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.

HOW TO USE

1. 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. 7) (The
are provided on the body.)
2. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
The rotational speed of the drill 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.
3. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
CAUTION
When using the hook, hang up the power tool firmly
not to drop accidentally.
If the power tool is dropped, it may lead to an accident.
When carrying the power tool with hooked to your
waist belt, do not fit any bit to the tip of power tool. If
the sharp bit such as drill is fitted to the power tool
when carrying it with hooked to your waist belt, you
will be injured.
Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Removing the hook.
Remove the screws fixing the hook with Philips screw
driver. (Fig. 8)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool
and tighten the screws to fix the hook firmly. (Fig. 9)
4. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig.10)
When releasing your finger from the remaining
battery indicator switch, the remaining battery
indicator lamp goes off. The table 4 shows the state
of remaining battery indicator lamp and the battery
remaining power.
