Operation—Battery Charger
• Charger plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) char-
gers. Unmodified plugs and matching outlets will
reduce risk of electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling, or unplugging the charger.
Keep cord away from heat, oil, sharp edges,
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
• To reduce the risk of electric shock, unplug
charger from outlet before attempting any main-
tenance or cleaning.
• If the temperature of the battery pack falls below
approximately 14 °F (−10 °C), charging automati-
cally stops to prevent degradation of the battery.
• It is strongly urged that the battery pack not be
charged when the temperature is BELOW 32 °F
(0 °C) or ABOVE 104 °F (40 °C). This is very
important in order to maintain optimal condition of
the battery pack.
• When charging a cool battery pack [below 32 °F
(0 °C)] in a warm place, leave the battery pack
at the place and wait for more than one hour to
warm up the battery to the level of the ambient
temperature.
• Cool down the charger when charging more than
two battery packs consecutively.
• Charge the battery pack in a well ventilated place;
do not cover the charger and battery pack with a
cloth, etc., while charging.
• Do not insert your fingers into contact hole, when
holding charger or any other occasions.
• This plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified
electrician to install the proper outlet. Do not
change the plug in any way
• To reduce risk of damaging the electric plug and
cord, pull by plug rather than cord when discon-
necting charger.
• Make sure cord is located so that it will not be
stepped on, tripped over, or otherwise subjected
to damage or stress.
• Do not operate charger with damaged cord or
plug—replace them immediately.
• An extension cord should not be used unless
absolutely necessary.
• Use of improper extension cord could result in a
risk of fire and electric shock.
• If extension cord must be used, make sure that:
– Pins on plug of extension cord are the same
number, size and shape as those of plug on
charger.
– Extension cord is properly wired and in good
electrical condition.
– Wire size is large enough for ampere rating of
charger as specified below.
