OPERATION

red LED does not come on after 30 minutes, this may

indicate a defective battery pack and should be

replaced.

After normal usage, a minimum of 1 hour of charging time

is required to fully recharge battery pack.

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 and battery pack in an area of

extreme heat or cold. They will work best at normal room

temperature.

NOTE: The charger and battery pack should be placed

in a location where the temperature is more than 50°F

but less than 100°F.

When batteries become fully charged, unplug the

charger from 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, this will cause the green LED to come on instead of
the red LED. After 30 minutes, reinsert the battery pack in
the charger. If the green LED continues to remain on, return
battery pack to your nearest Ryobi Authorized Service Center
for checking or replacing.
NOTE: This situation only occurs when continuous use of
the tool causes the batteries to become hot. It does not
occur under normal circumstances. Refer to

“CHARGING

A COOL BATTERY PACK” for normal recharging of batter-
ies. 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.
After all parts have been assembled properly, the battery
pack can now be attached to tool.
