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
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 charge indicator lamp of the 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
charge
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 confi rm that the battery being charged
with UC18YSL3 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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
