Cancer and Reproductive Harm -www.P65Warnings.ca.gov.
DANGER: Do not dispose of the batteries in a
re. The cell may explode. Check with local codes for
possible special disposal instructions.
CAUTION: Do not expose a battery pack or
appliance to re or excessive temperature. Exposure
to re or temperature above 130°C (265°F) may cause
explosion.
CAUTION:Disconnect the battery pack from the
appliance before making any adjustments, changing
accessories, or storing appliance. Such preventive safety
measures reduce the risk of starting the appliance acci-
dentally.
CAUTION: Have servicing performed by a
qualied repair person using only identical replacement
parts. This will ensure that the safety of the product is
maintained.
DANGER: Do not open or mutilate the batteries.
Released electrolyte is corrosive and may cause damage
to the eyes or skin. It may be toxic if swallowed.
CAUTION: Exercise care in handling batteries
in order not to short the battery with conducting materials
such as rings, bracelets, and keys. The battery or
conductor may overheat and cause burns. When battery
pack is not in use, keep it away from other metal objects,
like paper clips, coins, keys, nails, screws or other small
metal objects, that can make a connection from one
terminal to another. Shorting the battery terminals
together may cause burns or a re.
CAUTION: Do not use a battery pack or
appliance that is damaged or modied. Damaged or
modied batteries may exhibit unpredictable behavior
resulting in re, explosion or risk of injury.
CAUTION: Follow all charging instructions and
do not charge the battery pack or appliance outside of the
temperature range specied in the instructions. Charging

Make sure the power supply is normal household voltage,
120volts, 60Hz, AC only.
The battery charger should be operated in
temperatures between 39° F and 104° F.
The battery should be charged in a cool, dry place.

be required to achieve maximum run time/capacity.
Do not attempt to open the charger or the unit. There are
no customer serviceable parts inside. Call the customer
service help line at 1-800-633-1501 for assistance.
DO NOT incinerate battery packs even if they are severely
damaged or completely worn out. They can explode in a
re causing injury.

Disconnect charger from the power supply when not in use
to prevent damage to the charger during a power surge.
When fully charged, the battery can be safely stored
in

battery pack is needed.
To prevent permanent damage to the battery,
never store in a fully discharged condition.
WINTER STORAGE -
Fully recharge before storage
and then again every 90 days.
Since the battery will not develop a memory, it does
not have to be fully discharged before recharging.
A small leakage of liquid from the battery cells may occur
under extreme usage, charging or temperature conditions.
This does not indicate a failure. However, if the outer seal is
broken and this leakage gets on your skin.
a. Wash quickly with soap and water.
b. Neutralize with a mild acid
such as lemon juice or vinegar.
c. If the battery liquid gets in your eyes, ush them
with clean water for a minimum of 10 minutes and
seek immediate medical attention.
