CHARGING THE BATTERY PACK
See Figure 4.
The battery pack for this tool has been shipped in a low
charge condition to prevent possible problems. Therefore,
you should charge it until the light on front of charger changes
from flashing green to continuous green.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged. This is normal
for nickel-cadmium batteries.

Charge the battery pack only with the charger provided.
�
n
Make sure the power supply is normal house voltage,
120 volts, 60 Hz, AC only.

IMPORTANT INFORMATION FOR RECHARG-
ING A HOT BATTERY PACK
When using the saw continuously, the batteries in the
battery pack will become hot. You should let a hot
battery pack cool down for approximately 20 minutes before
attempting to recharge. When the battery pack becomes
discharged and is hot, the green LED will be off and the red
LED will begin flashing.
When the battery pack cools down to approximately 104°F
(40°C), the charger will automatically begin fast charge
mode.
If the Red LED continues to flash for more than 90 minutes,
and the green LED remains off, this may indicate a damaged
battery that will not charge.
IMPORTANT INFORMATION FOR RECHARG-
ING A COOL BATTERY PACK
If the battery pack is below normal temperature range, the
red LED will begin flashing and the green LED will be off.
When the battery warms to a temperature of more than
41°F (5°C), the charger will automatically begin fast charge
mode.
NOTE: Refer to “CHARGING THE 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 repair center
for electrical check. For the location of your nearest repair
center, please call 1-866-539-1710.
