Prior To Operation; How To Use - Hitachi Koki DB 10DL Instrucciones De Manejo

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 charger does not work while the battery
is mounted correctly, it is probable that the battery or
charger is malfunctioning. Take it to your authorized
Service Center.

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

How to make the batteries perform longer
○ 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.
1. Installing the bit
Always follow the following procedure to install driver
bit. (Fig. 4)
(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. Automatic spindle-lock mechanism
When the main switch is off , the bit is locked in place,
and the tool can be used as a manual screwdriver.
4. Confi rm that the battery is mounted correctly
5. 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, 5, 9 ... 21" on the clutch dial, or the black
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,
5, 9 ... 21" or the black dots.
○ Do not use with the clutch dial numeral between "21"
and the black line at the middle of the drill mark. Doing
so may cause damage (See Fig. 6).
6. 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 (See Fig. 5)
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, 5, 9 ... 21" on the clutch dial, and a black
dots. The tightening toque at position "1" is the weakest
and the torque is strongest at the highest number.
(3) Adjusting the tightening torque (See Fig. 5)
Rotate the clutch dial and line up the numbers "1, 5, 9 ...
21" 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.
○ 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.
○ Too long hammering may cause the screw broken due
to excessive tightening.
7. 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. 7) (The
are provided on the body).
8. 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.
9. Using the light
Pull the trigger switch to light up the light. The light keeps
on lighting while the trigger switch is being pulled. The
light goes out after releasing the trigger switch. (Fig. 8)
CAUTION
Do not look directly into the light. Such actions could
result in eye injury.
10. The scope and suggestions for uses
The usable scope for various types of work based on the
mechanical structure of this unit is shown in Table 2.
