(2) Regarding the temperature of the rechargeable battery.
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become hot
should be cooled for a while before being recharged.
Table 2 Recharging ranges of batteries
Rechargeable batteries
BSL1415S, BSL1415, BSL1425,
BSL1815S, BSL1815, BSL1825
(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.
Table 3 Charging time (At 20°C)
Charger
Battery
BSL1415S, BSL1815S Approx. 20 min. Approx. 35 min.
BSL1415, BSL1815 Approx. 22 min. Approx. 40 min.
BSL1425, BSL1825 Approx. 35 min. Approx. 75 min.
NOTE
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger's power cord from the
receptacle
5. Hold the charger fi rmly and pull out the battery
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
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 fi rst 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
○ 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.
Temperatures at which the
battery can be recharged
0°C – 50°C
UC18YFSL UC18YKSL
○ 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 microcomputer takes about 3 seconds
to confi rm that the battery being charged with UC18YKSL
or UC18YFSL are 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 a 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 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 driver 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 "
outer body.
