CHARGING THE 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 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.
TO CHARGE
 Charge the battery pack only with the charger provided.
� Make sure the power supply is normal household voltage,
120 volts, 60 Hz, AC only.
 Connect the charger to a power supply.
 Attach the battery pack to the charger by aligning the
raised ribs on the battery pack with the grooves in the
charger, then slide the battery pack onto the charger. See
Figure 2.
 The battery pack will become slightly warm to the touch
while charging. This is normal and does not indicate a
problem.
 Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.
 For average charge times, refer to the chart on the
following page.
 When the batteries become fully charged, unplug the
charger from the power supply and remove the battery
pack.
CHARGING A HOT BATTERY PACK
When using the tool 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.
If the battery pack is above normal temperature range, the
red LED will begin flashing and the green LED will be off.
When the battery pack cools down to approximately 104°F
(40°C), the charger will automatically begin fast charge mode.
CHARGING 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.
