Do not store or use the tool and battery pack in
•
locations where the temperature may reach or
exceed 104 °F (40 °C) (such as outside sheds or metal
buildings in summer). For best life store battery packs in
a cool, dry location.
NOTE: Do not store the battery packs in a tool with
the trigger switch locked on. Never tape the trigger
switch in the ON position.
Do not incinerate the battery pack even if it is severely
•
damaged or is completely worn out. The battery pack
can explode in a fire. Toxic fumes and materials are created
when lithium-ion battery packs are burned.
Do not expose a battery pack or appliance to fire or
•
excessive temperature. Exposure to fire or temperature
above 265 °F (130 °C) may cause explosion.
Follow all charging instructions and do not charge the
•
battery pack or appliance outside of the temperature
range specified in the instructions. Charging improperly or
at temperatures outside of the specified range may damage
the battery and increase the risk of fire.
If battery contents come into contact with the skin,
•
immediately wash area with mild soap and water. If
battery liquid gets into the eye, rinse water over the open
eye for 15 minutes or until irritation ceases. If medical
attention is needed, the battery electrolyte is composed of a
mixture of liquid organic carbonates and lithium salts.
Contents of opened battery cells may cause
•
respiratory irritation. Provide fresh air. If symptoms
persist, seek medical attention.
Battery liquid may be flammable if exposed to spark
•
or flame.
Never attempt to open the battery pack for any
•
reason. If the battery pack case is cracked or
damaged, do not insert into the charger. Do not crush,
drop or damage the battery pack. Do not use a battery pack
or charger that has received a sharp blow, been dropped,
run over or damaged in any way (e.g., pierced with a nail,
hit with a hammer, stepped on). Damaged battery packs
should be returned to the service center for recycling.

Storage Recommendations

The best storage place is one that is cool and dry, away
from direct sunlight and excess heat or cold. Store the fully
charged battery pack out of the charger.
Battery Pack Cleaning Instructions
Dirt and grease may be removed from the exterior of the
battery pack using a cloth or soft non-metallic brush. Do not
use water or any cleaning solutions.
Fuel Gauge Battery Packs (Fig. B)
Some battery packs include a fuel gauge. When the fuel
gauge button is pressed and held, the LED lights will
indicate the approximate level of charge remaining. This
does not indicate tool functionality and is subject to
variation based on product components, temperature, and
end-user application.
