Battery Packs

WARNING: Read all safety
warnings and all instructions for the battery
pack, charger and power tool. Failure to follow
the warnings and instructions may result in
electric shock, fire and/or serious injury.
• Do not charge or use the battery pack in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust. Inserting or removing the battery
pack from the charger may ignite the dust orfumes.
• NEVER force the battery pack into the charger. DO
NOT modify the battery pack in any way to fit into
a non-compatible charger as battery pack may
rupture causing serious personal injury. Consult
the chart at the end of this manual for compatibility of
batteries andchargers.
• Charge the battery packs only in designated
DeWALTchargers.
• DO NOT splash or immerse in water or otherliquids.
• 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.
• If battery contents come into contact with the skin,
immedicately 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.
