NOTE
The recharging time may vary according to the
ambient temperature.

Disconnect
the
charger’s
power
cord
from
the
receptacle.

and

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.
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).
In such a case,
fi
rst let the battery cool, then start
charging.
○
When the pilot lamp
fl
ickers (at 0.2-second 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 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.
MAINTENANCE
AND
INSPECTION
1.
Inspecting
the
mounting
screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
2.
Cleaning
of
the
charger
When the charger is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, for they melt
plastics.
3.
Store
idle
charger
When not in use, the charger should be stored in dry,
high or locked-up place — out of reach of children.
