UNPACKING
○ Carefully unpack the device.
○ Take out the accessories in tank before work.
CHARGING
Before using the power tool, charge the battery as follows.
<UC18YFSL (sold separately)>
1. Connect the charger's power cord to the
receptacle.
When connecting the plug of the charger to a
receptacle, the pilot lamp will blink in red. (See Table 1)
2. Insert the battery into the charger.
Firmly insert the battery into the charger as shown in
Fig. 3 (on page 2).
3. Charging
When inserting a battery in the charger, charging will
commence and the pilot lamp will light continuously in
red.
When the battery becomes fully recharged, the pilot
lamp will blink in red. (See Table 1)
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown in
Table 1, according to the condition of the charger or
the rechargeable battery.
Table 1: Indications of the pilot lamp
ON/OFF at 0.5 sec. intervals
Lights continuously
Lights for 1 sec. at intervals of
0.5 sec.
ON/OFF at 0.1 sec. intervals
NOTE
*1 If the red lamp continues to blink even after the charger
has been attached, check to confi rm that the battery
has been fully inserted.
*2 Battery overheated. Unable to charge.
Although charging will start once the battery has
cooled down even when left in situ, the best practice
is to remove the battery and allow it to cool down in a
shaded, well-ventilated location before charging.
*3 Malfunction in the battery or the charger
–
Fully insert the battery.
–
Check to confi rm that no foreign matter is stuck
to the battery mount or terminals. If there are no
foreign objects, it is probable that the battery or
charger is malfunctioning. Take it to your authorized
Service Center.
○ If the pilot lamp does not blink in red even though the
charger cord is connected to the power, it indicates that
the protection circuit of the charger may be activated.
Remove the cord or plug from the power and then
connect it again after 5 minutes or so. If this does not
cause the pilot lamp to blink in red, please take the
charger to the HiKOKI Authorized Service Center.
○ When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
bcompleted, give 5 minutes rest until the next charging.

NOTE
○ The recharging time may vary according to the ambient
temperature and power source voltage.
○ If charging takes a long time
–
Charging will take longer at extremely low ambient
temperatures. Charge the battery in a warm
location (such as indoors).
–
Do not block the air vent. Otherwise the interior will
overheat, reducing the charger's performance.
–
If the cooling fan is not operating, contact a HiKOKI
Authorized Service Center for repairs.
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.
