(2) Regarding the temperatures 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
BSL1430, BSL1830
(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)

Battery
BSL1430, BSL1830
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 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:
When the battery charger has been continuosly 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 is recharged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
map light in green.
Temperatures at
which the battery
can be recharged
0°C – 50°C
UC18YRSL
Approx. 45 min.
The battery will not be recharged. In such a case, let
the battery cool before charging.
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.
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. Confirm 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, 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. 6)
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 Fig. 5)
(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.
