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 differs 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 the

dots. The tightening toque at position “1” is the

weakest and the torque is strongest at the highest

number. (See Figs. 4, 6)

(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:

⅜ 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.

⅜ Too long hammering may cause the screw broken

due to excessive tightening.

3. Rotation to Impact changeover <DV14DL2 /

DV18DL2> (See Fig. 6)

The “Rotation (Rotation only)” and “Impact (Impact

+ Rotation)” can be switched by aligning the drill

mark “

” or the hammer mark “ ” with the triangle

mark on the outer body.

⅜ To make holes in the metal, wood or plastic, switch

to “Rotation (Rotation only)”.

⅜ To make holes in bricks or concrete blocks, switch to

“Impact (Impact + Rotation)”.

CAUTION:

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.

4. Change rotation speed

Operate the shift knob to change the rotational speed.

Move the shift knob in the direction of the arrow (see

Figs. 8 and 9).

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:

⅜ 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.

⅜ When setting the shift knob to “HIGH” (high speed)

and the position of the clutch dial is “17” or “22”, it

may happen that the clutch is not engaged and that

the motor is locked. In such a case, please set the

shift knob to “LOW” (low speed).

⅜ 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.

5. 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 4.

and the battery life will be shortened. Leave the battery

and recharge it after it has cooled for a while.

CAUTION:

⅜ If the battery is charged while it is heated because it

has been left for a long time in a location subject to

direct sunlight or because the battery has just been

used, the pilot lamp of the charger lights up green. In

such a case, first let the battery cool, then start

charging.

⅜ When the pilot lamp flickers in red (at 0.2-seconds

intervals), check for and take out any foreign objects

in the charger’s battery connector. If there are no

foreign objects, it is probable that the battery or

charger is malfunctioning. Take it to your authorized

Service Center.

⅜ Since the built-in micro computer takes about 3

seconds to confirm that the battery being charged

with UC18YMRL / UC18YRL 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.

⅜ Check the voltage of the in-car power source when

the pilot lamp flickers in green (every 0.2 seconds)

continuously. (UC18YMRL)

If the voltage is 12V or lower, it indicates that the car

battery has weakened and cannot be charged.

⅜ If the pilot lamp does not blink in red (every second)

even though the charger cord or cigarette lighter

connecting plug is connected to the power, it indicates

that the protection circuit of the charger may be

activated.

Remove the cord or plug from the power and then

connect it again after 30 seconds or so. If this does

not cause the pilot lamp to blink in red (every second),

please take the charger to the Hitachi 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

1. Confirm the clutch dial position (see Figs. 4, 6)

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.

(3) When using this unit as an impact drill, align the

clutch dial hammer mark “ ” with the triangle mark

on the outer body.

CAUTION:

⅜ The clutch dial cannot be set between the numerals

“1, 3, 5 ... 22” or the dots.

⅜ 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 Figs. 5, 7)
