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 (o
ff
for 0.5 seconds) (UC18YFSL)
or lights up green. (UC18YML2). In such a case,
fi
rst let
the battery cool, then start charging.
○
When the pilot 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 con
fi
rm that the battery being charged with UC18YFSL
/ UC18YML2 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.
○
Check the voltage of the in-car power source when the pilot
lamp blinks in green (At 1-second intervals). (UC18YML2)
If the voltage is 12 V or lower, it indicates that the car
battery has weakened and cannot be charged.
○
If the pilot lamp does not blink in red (every second) even
though the charger cord or cigarette lighter connecting
plug 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 30 seconds or so. If this does
not cause the pilot lamp to blink in red (every second),
please take the charger to the HiKOKI Authorized
Service Center.

1. How to operate operation panel
(1) Power switch ON (See
Fig. 4
)
Under the condition of “Power switch OFF”, push and
hold on Power switch more than 1 second, then power
indicator lights in Green.
NOTE
Do not press the push lever and/or pull the trigger during
the process of turning the power switch ON.
Doing so will prevent the power switch from turning ON.
[Auto power o
ff
]
When the power is turned on but the Nailer is not used
for 30 minutes, the Nailer is automatically turned o
ff
. To
turn on again, press the power switch.
WARNING
Never leave the Nailer with the power on. This could
result in an accident.
(2) Power switch OFF (See
Fig. 4
)
Under the condition of “Power switch ON”, push and
hold on Power switch more than 1 second, then power
indicator goes o
ff
.
Under the condition of “Power switch ON”, functions
below are active.
(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.

Temperatures at
which the battery
can be recharged

0°C – 50°C
(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.
<UC18YML2>
Especially, using a DC 12V in-car power source may
require longer recharging time at high temperatures.
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 or cigarette lighter socket.
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.
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.
