4. Disconnect the charger’s power cord from the

receptacle.

5. Hold the charger firmly and pull out the battery.

NOTE:

After operation, pull out batteries from the charger

first, and then keep the batteries properly.

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 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 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:

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 batetery 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-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.

⅜ 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:

⅜ The cap cannot be set between the numerals “1, 4, 7

... 22” or the black dots.

⅜ 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 a 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:

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. 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:

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 cap is between“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).

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.
