CHARGING BATTERIES
See Figures 11 and 12.
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.
Follow these directions when charging batteries.
■ Charge battery pack only with the charger provided.
■ Make sure power supply is normal house volt-
age, 120 volts, 60 Hz, AC only.
■ Connect charger to power supply.
■ Place battery pack in charger. 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. When your battery pack becomes fully
charged, the red light will turn off and the green light
will turn on.
NOTE: 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 additional 15 minutes, the battery pack is damaged
and will not accept charge. See Table 1.
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 temperature.

RECHARGING HOT BATTERIES
When using your Speed 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 Speed Saw causes the batteries to become hot. It
does not occur under normal circumstances. Refer to
"CHARGING BATTERIES" for normal recharging of
batteries. If the charger does not charge your battery
pack under normal circumstances, return both the battery
pack and charger/charging assembly to your nearest
Ryobi Authorized Service Center for electrical check.
