(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
Battery type
BSH2420
(3) Regarding recharging time
Depending on the type of the battery, the charging
time will become as shown in Table 3.
Table 3 Charging time (At 20°C)
Battery type
BSH2420
NOTE: The charging time may vary according to ambient
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.
Indications of the pilot lamp
Blinks Lights for 0.5 seconds. Does not light
for 0.5 seconds. (off for 0.5 seconds)
Lights Lights continuously
Blinks Lights for 0.5 seconds. Does not light
for 0.5 seconds. (off for 0.5 seconds)
Blinks Lights for 1 second. Does not light
for 0.5 seconds. (off for 0.5 seconds)
Temperatures at
which the battery
can be recharged
0°C – 50°C
Recharging time
Approx. 60 min.
(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, first let the battery
cool, then start charging.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC24SGH 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. Mounting the drill bit (Fig. 5, 6)
CAUTION
To prevent accidents, make sure to turn the switch
off.
NOTE
When using tools such as drill bits, etc., make sure
to use the genuine parts designated by our company.
(1) Clean the shank portion of the drill bit.
(2) Insert the drill bit in a twisting manner into the tool
holder until it latches itself. (Fig. 5)
(3) Check the latching by pulling on the drill bit.
(4) To remove the drill bit, fully pull the grip in the
direction of the arrow and pull out the drill bit.
2. Confirm that the battery is mounted correctly.
3. Installation of dust cup or dust collector (B) (Optional
accessories) (Fig. 7, Fig. 8)
When using a rotary hammer for upward drilling
operations attach a dust cup or a dust collector (B)
to collect dust or particles for easy operation.
Installing the dust cup
Use the dust cup by attaching to the drill bit as
shown in Fig. 7.
When using a bit which has big diameter, enlarge
the center hole of the dust cup with this rotary
hammer.
