WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California 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.
• Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing
dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmfulchemicals.

WARNING: Use of this tool can generate and/
or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles
away from face andbody.

WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19)
during use. Under some conditions and duration
of use, noise from this product may contribute to
hearingloss.

CAUTION: When not in use, place tool on its side
on a stable surface where it will not cause a
tripping or falling hazard. Some tools with large
battery packs will stand upright on the battery pack
but may be easily knockedover.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be
caught in movingparts.

Important Safety Instructions for All
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.
