(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.

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
CAUTION
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
completed, give 15 minutes rest until the next charging.
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.
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 UC18YFSL charger lights for 1 second,
does not light for 0.5 seconds (off for 0.5 seconds), or
the charge indicator lamp of UC18YSL3 charger lights
for 0.3 seconds, does not light for 0.3 seconds (off for
0.3 seconds). In such a case, fi rst let the battery cool,
then start charging.

○ When the pilot lamp or charge indicator lamp fl ickers in
red (at 0.2-seconds 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 micro computer takes about 3
seconds to confi rm that the battery being charged with
charger 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.
○ If the pilot lamp or charge indicator lamp does not blink
in red (every second) 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 from the power and then connect it
again after 30 seconds or so. If this does not cause
the pilot lamp or charge indicator lamp to blink in red
(every second), please take the charger to the HiKOKI
Authorized Service Center.
HOW TO RECHARGE USB DEVICE (ONLY WITH
UC18YSL3 CHARGER)
(1) Select a charging method
Depending on the charge method selected, either the
battery is inserted into the charger or the power cord is
plugged into an outlet.
○ Charging a USB device from an electrical outlet
(Fig. 8-a)
○ Charging a USB device and battery from an electrical
outlet (Fig. 8-b)
(2) Connect the USB cable. (Fig. 9)
Pull back the rubber cover and fi rmly plug in a
commercially available USB cable (appropriate to the
device being charged) into the USB port.
(3) When charging is completed
○ To verify charge status, check the USB device.
○ Unplug the power cord from the electrical outlet.
○ Place the rubber cover over the USB port.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by following the
precautions.
2. Power switch
Ensure that the power switch is in the OFF position. If the
battery is attached to the body while the power switch
is in the ON position, the power tool will start operating
immediately, which could cause a serious accident.
3. Prepare a stable wooden workbench suitable for planing
operation. As a poorly balanced workbench creates a
hazard, ensure it is securely positioned on fi rm, level
ground.
