Malfunction in the battery
or the charger
The battery temperature
is high, making recharging
impossible.
(2) Regarding the temperatures of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in the table 2, and batteries that have become
hot should be cooled for a while before being
recharged.
Table 2 Recharging ranges of batteries
(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)
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 short when using them the first and second time.
Temperatures at
Rechargeable batteries which the battery
can be recharged
EB1820L –5°C – 60°C
Charger
Battery
UC24YFA
EB1820L Approx. 50 min.
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 been cooled for a
while.
CAUTION
䡬 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.
䡬 When the pilot lamp flickers in red quickly (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.
䡬 Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC24YFA 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.

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, 3, 5 ... 22” on the cap, or the white
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:
䡬 The cap cannot be set between the numerals “1, 3,
5 ... 22” or the white dots.
䡬 Do not use with the cap numeral between “22” and
the white 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, 3, 5 ... 22” on the cap, and a white 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 cap and line up the numbers “1, 3, 5, ...
22” on the cap, or the white 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:
䡬 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.
䡬 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:
䡬 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.
䡬 When setting the shift knob to “HIGH” (high speed)
and the position of the cap is “17” or “22”, it may
happen that the clutch does not engage and that the
motor is locked. In such a case, please set the shift
knob to “LOW” (low speed).
䡬 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.
4. The scope and suggestions for uses

5. How to select tightening torque and rotational speed
Table 5
14
CAUTION:
䡬 The selection examples shown in Table 5 should be
considered as general standard. As different types of
tightening screws and different materials to be
tightened are used in actual works proper adjustments
are naturally necessary.
䡬 When using the driver drill with a machine screw at
HIGH (high speed), a screw may damage or a bit may
loose due to the tightning torque is too strong. Use
the driver drill at LOW (low speed) when using a
machine screw.
6. Mounting and dismounting of the bit
(1) After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve by
turning it toward the right (in the clockwise direction
as viewed from the front). (See Fig. 8)
䡬 If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened additionally.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning
it toward the left (in the counter-clockwise direction
as viewed from the front). (See Fig. 8)
CAUTION:
䡬 When it is no longer possible to loosen the sleeve,
use a vise or similar instrument to secure the bit. Set
the clutch mode between 1 and 11 and then turn the
sleeve to the loose side (left side) while operating the
clutch. It should be easy now to loosen the sleeve.
7. Confirm that the battery is mounted correctly.
8. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the
bit counterclockwise. (See Fig. 9). (The
L
and
R
marks are provided on the body.)
9. Switch operation
䡬 When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
䡬 The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
NOTE:
䡬 A buzzing noise is produced when the motor is about
to rotate; This is only a noise, not a machine failure.
10. Using the hook
CAUTION:
䡬 When using the hook, pay sufficient attention so that
the main equipment does not fall. If the tool falls,
there is a risk of accident.
䡬 Do not attach the tip tool except phillips bit to the tool
main unit when carrying the tool main unit with the
hook suspended from a waist belt.
Injury may result if you carry the equipment
suspended from the waist belt with sharp tipped
components such as drill bit attached.
