Prior To Operation; How To Use - Hitachi DV 14DVA Bedienungsanleitung

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 dis-
charge might be short 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 com-
pletely 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 been cooled for
a while.
CAUTION
If the battery has been heated right after operation
(or due to sunlight, etc.), the charger's pilot lamp
may not light in red. In such a case, first let the
battery cool, then start charging.
When the pilot lamp flickers in red quickly (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 UC14YF/UC14YF2 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 working environment is suitable by
following the precautions.

HOW TO USE

1. Confirm the cap position
The three modes of screwdriver, drill and impact drill
can be switched by the position of the cap in this tool.
(1) When the tool is used as a screwdriver, align the
number displayed on the cap from "1" to "5" to the
triangle mark of the housing.
(2) When the tool is used as a drill, align the drill mark
" " displayed on the cap to the triangle mark of
the housing.
(3) When the tool is used as an impact drill, align the
hammer mark " " displayed on the cap to the
triangle mark of the housing.
CAUTION
2. Tightening torque adjustment

CAUTIONS
3. Rotation to Impact changeover (See Figs. 4, 5).
CAUTION
4. Change rotation speed
CAUTION
(See Figs. 4, 5.)
Align the number and mark on the cap to the triangle
mark of the housing. The middle point of the numbers
and marks on the cap cannot be secured.
Tightening torque should correspond in its intensity
to the screw diameter. When too strong power is
used, the screw head may be broken or be injured.
Be sure to adjust the cap position according to the
screw diameter.
Tightening torque should be changed according to
the screw type and the materials to be tightened.
Guidance of the tightening torque is indicated on
the cap of this unit with numerals "1", "2", "3",
"4" and "5". The minimum power is from "1"
position and bigger numeral is the stronger power
(see Figs. 4, 5).
Rotate the cap and set to one of the numerals.
Adjust the torque by cap rotation in such a way
that when the torque is too strong, set to the next
smaller numeral and set to the next larger numeral
when too weak.
The motor rotation may be locked to cease while
the unit is used as drill. While operating the impact
drill, take care not to lock the motor.
Too long hammering may cause the screw broken
due to excessive tightening.
The "Rotation (Rotation only)" and "Impact (Impact
+ Rotation)" can be switched by aligning the drill
mark " " or the hammer mark" " to the triangle
mark of the housing.
To make holes in the metal, wood or plastic, switch
to "Rotation (Rotation only)".
To make holes in bricks or concrete blocks, switch
to "Impact (Impact + Rotation)".
If an operation which is normally performed at the
"Rotation" setting is performed at "Impact " setting,
the effect of making holes does not only increase
but it may also damage the bit or other parts.
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" (low speed),
the drill rotates at a low speed. When set to "HIGH"
(high speed), the drill rotates at a high speed.
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 "4" or "5", 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.
