Prior To Operation; How To Use - Hitachi DS14DBL Handling Instructions Manual

English
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 fi rst 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.
CAUTION
○ When the battery charger has been continuously 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 fl ickers 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 Hitachi authorized Service
Center.

PRIOR TO OPERATION

○ Setting up and checking the work environment
Check if the work environment is suitable by following the
precautions.

HOW TO USE

1. Confi rm the clutch dial position (See Fig. 5)
The tightening torque of this unit can be adjusted
according to the clutch dial position, at which the clutch
dial is set.
(1) When using this unit as a screwdriver, line up the one of
the numbers "1, 3, 5 ... 22" on the clutch dial, or the dots,
with the triangle mark on the outer body.
(2) When using this unit as a drill, align the clutch dial drill
mark " " with the triangle mark on the outer body.
CAUTION
○ The clutch dial cannot be set between the numerals "1, 3,
5 ... 22" or the dots.
○ Do not use with the clutch dial numeral between "22"
and the line at the middle of the drill mark. Doing so may
cause damage (See Fig. 6).

2. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity to
the screw diameter. When too strong torque is used,
the screw head may be broken or be injured. Be sure
to adjust the clutch dial position according to the screw
diameter.
(2) Tightening torque indication
The tightening torque diff ers depending on the type of
screw and the material being tightened.
The unit indicates the tightening torque with the numbers
"1, 3, 5 ... 22" on the clutch dial, and a dots. The tightening
torque at position "1" is the weakest and the torque is
strongest at the highest number (See Fig. 5).
(3) Adjusting the tightening torque
Rotate the clutch dial and line up the numbers "1, 3, 5 ...
22" on the clutch dial, or the dots, with the triangle mark
on the outer body. Adjust the clutch dial in the weak or the
strong torque direction according to the torque you need.
CAUTION
○ The motor rotation may be locked to cease while the unit
is used as drill. While operating the driver drill, take care
not to lock the motor.
○ Too long hammering may cause the screw broken due to
excessive tightening.
3. Change rotation speed
Operate the shift knob to change the rotational speed.
Move the shift knob in the direction of the arrow (See
Figs. 7 and 8).
When the shift knob is set to "LOW", the drill rotates at a
low speed. When set to "HIGH", the drill rotates at a high
speed.
CAUTION
○ When changing the rotational speed with the shift knob,
confi rm that the switch is off .
Changing the speed while the motor is rotating will
damage the gears.
○ If the motor is locked, immediately turn the power off . If
the motor is locked for a while, the motor or battery may
be burnt.
Be sure to turn the shift knob.
4. Change rotation speed mode selector function
(Fig. 9)
CAUTION
○ Do not subject the switch panel to shock or damage.
○ Select high/low mode while the trigger switch is released.
Failure to do so could result in malfunction.
(1) Change rotation speed selector switch
The rotation speed changes in 4 steps each time the
high/low selector switch is pressed.
