Prior To Operation; How To Use - Hitachi Koki DS 14DMR Instrucciones De Manejo

English
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.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC14YFA/UC24YFA/UC18YRL/UC18YFL is taken
out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is
reinserted within 3 seconds, the battery may not be
properly charged.

PRIOR TO OPERATION

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

HOW TO USE

1. Confirm the cap position (see Fig. 4)
The tightening torque of this unit can be adjusted
according to the cap position, at which the cap is set.
(1) When using this unit as a screwdriver, line up the one
of the numbers "1, 4, 7 ... 22" on the cap, or the black
dots, with the triangle mark on the outer body.
(2) When using this unit as a drill, align the cap drill mark
" " with the triangle mark on the outer body.
CAUTION:
The cap cannot be set between the numerals "1, 4, 7
... 22" or the black dots.
Do not use with the cap numeral between "22" and
the black line at the middle of the drill mark. Doing so
may cause damage. (See Fig. 5)
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 cap position according to the
screw diameter.

(2) Tightening torque indication
The tightening torque differs depending on the type
of screw and the material being tightened.
The unit indicates the tightening torque with the
numbers "1, 4, 7 ... 22" on the cap, and the black
dots. The tightening toque at position "1" is the
weakest and the torque is strongest at the highest
number. (See Fig. 4)
(3) Adjusting the tightening torque
Rotate the cap and line up the numbers "1, 4, 7 ... 22"
on the cap, or the black dots, with the triangle mark
on the outer body. Adjust the cap 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. 6 and 7).
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, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
When setting the shift knob to "HIGH" (high speed)
and the position of the cap is bitween "16" and "22",
it may happen that the clutch does not engaged and
that the motor is locked. In such a case, please set the
shift knob to "LOW" (low speed).
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.
