CHARGING BATTERY PACK
The battery pack for this tool has been shipped in a
low charge condition to prevent possible problems.
Therefore, you should charge it prior to use.
Note: Batteries will not reach full charge the first time
they are charged. Allow several cycles (cutting
followed by recharging) for them to fully charge.
WARNING:
RISK OF ELECTRIC SHOCK. DO NOT TOUCH
UNINSULATED PORTION OF OUTPUT
CONNECTOR OR UNINSULATED BATTERY
TERMINAL.
TO CHARGE
■ Charge battery pack only with the charger pro-
vided.
■ Make sure power supply is normal house
voltage, 120 volts, 60 Hz, AC only.
■ Connect charger to power supply.
■ Place battery pack in charger. See Figure 4. Align
raised rib on battery pack with groove in charger.
■ Press down on battery pack to be sure contacts on
battery pack engage properly with contacts in
charger. When properly connected, red light will
turn on.
■ Normally, the yellow and green lights on the
charger will come on. This indicates charger is in
control charge mode and should switch to fast
charge mode within 5 minutes. When charger is in
fast charge mode the red light will come on. If after
a period of 15 minutes the yellow and green lights
remain on, remove the battery pack, wait 1 minute
and reinsert battery pack in charger. If the yellow
and green lights continue to remain on an addi-
tional 15 minutes, the battery pack is damaged and
will not accept charge.
■ When your battery pack becomes fully charged,
the red light will turn off and the green light will turn
on.
■ After normal usage, 1 hour of charge time is
required to be fully charged. A minimum charge
time of 1 to 1-1/2 hours is required to recharge a
completely discharged tool.
■ The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
■ DO NOT place charger in an area of extreme heat
or cold. It will work best at normal room tempera-
ture.
IMPORTANT INFORMATION FOR RECHARG-
ING HOT BATTERIES
When using your saw continuously, the batteries in
your battery pack become hot. You should let a hot
battery pack cool down for approximately 30 minutes
before attempting to recharge.
Note: This situation occurs when continuous use of
your saw causes the batteries to become hot. It does
not occur under normal circumstances. Refer to
"Charging Battery Pack" for normal recharging of
batteries. If the charger does not charge your battery
pack under normal circumstances, return both the
battery pack and charger to your nearest Ryobi
Authorized Service Center for electrical check.
