could burst, causing personal injury and damage.
• Unplug the charger from the outlet before attempting any maintenance or clean-
ing.
• Do not disassemble the charger; take it to a qualified service technician when
service or repair is required. Improper reassembly may result in a risk of electric

OPERATION
Always use a battery pack until it can
no longer provide the necessary pow-
er.
Follow these steps to charge a battery
pack.
1. Slide the battery connector of the
battery pack you want to charge
into the CHARGING JACK.
Cautions:
• This charger works only with 4.8-
volt, 7.2-volt and 9.6-volt nickel-
cadmium battery packs. Charging
other types of battery packs could
damage the battery packs.
(illus)
• Be sure the battery pack is rated at
4.8 V, 7.2 V, or 9.6 V.
• Avoid charging fully-charged bat-
tery packs. Doing so can damage
the battery pack or cause it to lose
some of its storage capacity.
Warning: Connect or disconnect
the battery plug only when the AC
cord is disconnected. Otherwise,
arcing and burning might result.
• Charge battery packs only at room
temperature (65-80×F). Charging
battery packs in hot areas can per-
manently reduce the battery pack’s
power capacity.
Notes:
• If the connector does not fit, turn
it over and try again. Do not force
it.
• To protect battery packs, allow
them to cool for 20 minutes before
recharging them.
• If you want to charge a 4.8 volt
nickel-cadmium battery pack,
plug the small end of the sup-
plied adapter cord fully into the
battery pack’s connector. Then
plug the adapter cord’s large end
fully into the CHARGING JACK.
• Charge only one battery pack at a
time.

the
battery
(illus)
• If the battery pack you want to
charge is a new one or has not
been used for more than 3
months, leave it in the charger
for 24 hours, even if the
CHARGE indicator turns off.
Caution: Be sure to insert the bat-
tery pack into the upper side of the
comprtment first. Then secure the
battery pack in place so it pushes
down the applicable voltage selec-
tor sensors and the two latches at
the lower side of the compartment.
• If the CHARGE indicator flashes,
check the battery connection.
4. When the CHARGE indicator turns
off, unplug the charger’s AC cord
then disconnect the battery pack.
3. Plug the AC cord into a standard
AC outlet.
Notes:
• High-capacity 7.2-volt, 1700
mAh, and 9.6-volt, 950 mAh bat-
tery packs might require two
charging cycles to fully charge.
(illus)
• When you disconnect a 4.8-volt
or 9.6-volt battery pack from the
compartment, be sure to take
out the lower part of the battery
pack first.
Notes:
• After 7 seconds, the charger
automatically selects the appro-
priate charging current.
• When you disconnect a 7.2-volt
battery pack from the compart-
ment, take out the upper part of
the battery pack first.
• The CHARGE indicator lights
when the battery pack is charg-
ing, automatically turns off when
the battery pack finishes charg-
ing, and flashes when the bat-
tery pack fails to charge.
