(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
○ 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 for 1 second, does not
light for 0.5 seconds (off for 0.5 seconds). In such a case,
fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers (at 0.2-second 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.
○ Since the built-in micro computer takes about 3 seconds
to confi rm that the battery being charged with UC18YKSL
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

Setting up and checking the work environment
Check if the work environment is suitable by following the
precautions.
HOW TO USE
1. Confi rm the clutch dial position (See Fig. 4)
The three modes of screwdriver, drill and impact drill can
be switched by the position of the clutch dial in this unit.
(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
○ The clutch dial cannot be set between the numerals "1, 3,
5 ... 22" or the dots.
○ 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 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 clutch dial position according to the screw
diameter.
(2) Tightening torque indication
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, 3, 5 ... 22" on the clutch dial, and the dots. The
tightening torque 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 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
○ The motor rotation may be locked to cease while the unit
is used as drill. While operating the combi drill, take care
not to lock the motor.
○ Too long hammering may cause the screw broken due to
excessive tightening.
3. Rotation to Impact changeover (See Fig. 4)
The "Rotation (Rotation only)" and "Impact (Impact +
Rotation)" can be switched by aligning the drill mark
" " or the hammer mark "
the outer body.
○ 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)".
CAUTION
○ If an operation which is normally performed at the
"Rotation" setting is performed at "Impact" setting, the
eff ect of making holes does not only increase but it may
also damage the bit or other parts.
○ If it is hard to turn the clutch dial to hammer mark "
position, turn the chuck slightly in either direction and then
turn the clutch dial to hammer mark "
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. 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,
confi rm 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 clutch dial is bitween "15" 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.
○ To extend the lifetime, the lithium-ion battery equips with
the protection function to stop the output. Therefore, if the
tool is overloaded, the motor may stop. However, this is
not the trouble but the result of protection function. In this
case, release the switch of tool and eliminate the causes
of overloading.
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.
