Before using the power tool, charge the battery as follows.
1. Connect the charger power cord to the receptacle
Connecting the power cord will turn on the charger.
2. Insert the battery into the charger
Insert the battery firmly while observing its direction,
until it contacts the bottom of the charger
(
See Fig. 4
)
(the pilot lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the
power cord from the receptacle and check the
battery mounting condition.
The pilot lamp goes off to indicate that the battery is
fully charged.
The battery charging time becomes longer when a
temperature is low or the voltage of the power source
is too low.
(1) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become
hot should be cooled for a while before being
recharged.
(2) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.
When the pilot lamp does not go off even if more
than 120 minutes have elapsed after starting of the
charging, stop the charging and contact your HITACHI
AUTHORIZED SERVICE CENTER.
CAUTION
If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may
not light up. At that time, cool the battery first,
then start charging.
3. Disconnect the charger power cord from the
receptacle
4. Hold the charger tight and pull out the battery
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an extended
period is not activated, the electric discharge might
be low when using them the first and second time.
This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging
the batteries 2 – 3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(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.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by the
above precautions.
HOW TO USE
1. Installing the bit
Always follow the following procedure to install driver
bit. (Fig. 5)
(1) Pull the guide sleeve forward.
(2) Insert the bit into the hexagonal hole in the socket.
(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.
2. Removing the bit
Please do the opposite point on the method of
installing bit.
3. Confirm 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 selector button.
The L-side of the selector button is pushed to turn the
bit counterclockwise (See Fig. 6) (The
L
and
R
marks are provided on the body).
5. Switch operation
CAUTION
⅜ Before using, confirm that the switch lever returns
to its original position when pulled and then
released. Failure of the switch lever to operate
properly can result in injury.
⅜ Do not hang the angle impact driver from a belt
and the like by the switch lever. The angle impact
driver may drop causing an accident. In addition,
this can also damage the switch lever.
⅜ When carrying the angle impact driver, confirm
that the lock button is in the OFF position. Carrying
the angle impact driver with the lock switch in the
ON position can cause the switch to inadvertently
be turned on resulting in injury.
⅜ Do not carry the angle impact driver by the switch
lever when carrying. This can cause a malfunction.
⅜ Be careful not to pinch your finger between the
switch lever and the angle impact driver. This can
cause an injury.
⅜ The switch is turned on when the switch lever is
pulled after having slid the lock button to the ON
position, and is turned off when the switch lever is
released. (See Fig. 7)
⅜ 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.
⅜ Always make sure to return the lock button to the
OFF position after using. (See Fig. 7)
NOTE
⅜ A buzzing noise is produced when the motor is about
to rotate. This is only a noise, not a machine failure.
