SAFETY RULES FOR CHARGER
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS.
Failure to follow all instructions listed below, may result in
electric shock, fire and/or serious personal injury.
n Before using battery charger, read all instructions and
cautionary markings in this manual, on battery charger,
battery, and product using battery to prevent misuse of
the products and possible injury or damage.
CAUTION:
To reduce the risk of electric shock or damage to
the charger and battery, charge only nickel-cadmium
rechargeable batteries as specifically designated on your
charger. Other types of batteries may burst, causing personal injury or damage.
n Do not use charger outdoors or expose to wet or damp
conditions. Water entering charger will increase the risk
of electric shock.
n Use of an attachment not recommended or sold by the
battery charger manufacturer may result in a risk of
fire, electric shock, or injury to persons. Following this
rule will reduce the risk of electric shock, fire, or serious
personal injury.
n Do not abuse cord or charger. Never use the cord to
carry the charger. Do not pull the charger cord rather than
the plug when disconnecting from receptacle. Damage
to the cord or charger could occur and create an electric
shock hazard. Replace damaged cords immediately.
n Make sure cord is located so that it will not be stepped
on, tripped over, come in contact with sharp edges
or moving parts or otherwise subjected to damage or
stress. This will reduce the risk of accidental falls, which
could cause injury, and damage to the cord, which could
result in electric shock.
n Ke e p cord and char ger from he at to preve nt
damage to housing or internal parts.
n Do not let gasoline, oils, petroleum-based products,
etc. come in contact with plastic parts. They contain
chemicals that can damage, weaken, or destroy plastic.
n An ext ens ion cord should not be use d unl ess
absolutely necessary. Use of improper extension
cord could result in a risk of fire and electric shock. If
extension cord must be used, make sure:
a. Tha t pins on plug of ext ensio n cord are the
sam e num ber, size and s hape as th ose o f
plug on charger.
b. That exten sion cord is prop erly wire d and in
good electrical condition; and
c. That wire size is large enough for AC ampere
rating of charger as specified below:
Cord Length (Feet) 25’ 50’ 100’
Cord Size (AWG) 16 16 16
NOTE: AWG = American Wire Gauge
n Do not operate charger with a damaged cord or
plug, which could cause shorting and electric shock. If
damaged, have the charger replaced by an authorized
serviceman.
n Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take
it to an authorized serviceman for electrical check to
determine if the charger is in good working order.
n Do not disassemble charger. Take it to an authorized
serviceman when service or repair is required. Incorrect
reassembly may result in a risk of electric shock or fire.
n Unplug charger from ou tlet befor e attempti ng
any maintenance or cleaning to reduce the risk of
electric shock.
n Disconnect charger from the power supply when
not in use. This will reduce the risk of electric shock or
damage to the charger if metal items should fall into the
opening. It also will help prevent damage to the charger
during a power surge.
n Risk of electric shock. Do not touch uninsulated portion
of output connector or uninsulated battery terminal.
n Save these instructions. Refer to them frequently
and use them to instruct others who may use this
tool. If you loan someone this tool, loan them these
instructions also to prevent misuse of the product and
possible injury.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks
that are specially designed to filter out microscopic particles.

OPERATION
CHARGING THE BATTERY PACK
Battery packs for this tool are shipped in a low charge condition to prevent possible problems. Therefore, you should
charge them until the green LED on the front of the charger
comes on.
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.
CHARGING A COOL BATTERY PACK
See Figure 3.
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack and
charger to your nearest Ryobi Authorized Service Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
n Connect the charger to the power supply.
n Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
n Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOT E: Th e gre en LE D wi l l rem ain on unt il th e
battery pack is removed from the charger or charger is
disconnected from the power supply.
n If both yellow and green LEDs come on, this indi-
cates a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
n The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
n 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.
n When batteries become fully charged, unplug the
charger from power supply and remove the battery
pack.

CHARGING A HOT BATTERY PACK
When using a 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 a
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 batteries. 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.
