• If defective, try to repeat the conditions a second time by removing and reinstalling the battery
pack. If the LED status repeats a second time, try charging a different battery.
• If a different battery charges normally, dispose of the defective pack (see
Maintenance
section).
• If a different battery also indicates “Defective,” the charger may be defective.
Battery packs for this tool are shipped in a low charge
condition to prevent possible problems. Therefore, you
should charge the pack until the light on the front of the
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 5.
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.
THE FOLLOWING INSTRUCTIONS ARE FOR RIDGID NICKEL-CADMIUM BATTERY PACKS AND
CHARGERS.
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 30 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.
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.
