1) Work Area Safety
a ) Keep work area clean and well lit. Cluttered or dark
areas inviteaccidents.
b ) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create
sparks which may ignite the dust orfumes.
c ) Keep children and bystanders away while
operating a power tool. Distractions can cause you
to losecontrol.
Electrical Safety
a ) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electricshock.
b ) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed orgrounded.
c ) Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electricshock.
d ) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electricshock.
e ) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electricshock.
f ) If operating a power tool in a damp location
is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI
reduces the risk of electricshock.
Personal Safety
a ) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A

Important Safety Instructions for All
Battery Chargers
WARNING: Read all safety warnings, instructions,
and cautionary markings for the battery pack,
charger and product. Failure to follow the
warnings and instructions may result in electric
shock, fire and/or seriousinjury.
• DO NOT attempt to charge the battery pack with
any chargers other than a DeWALT charger. DeWALT
chargers and battery packs are specifically designed to
worktogether.
• These chargers are not intended for any uses other
than charging DeWALT rechargeable battery packs.
Charging other types of battery packs may cause them to
overheat and burst, resulting in personal injury, property
damage, fire, electric shock orelectrocution.
• Do not expose the charger to rain orsnow.
• Do not allow water or any liquid to entercharger.
• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.
• Make sure that the cord is located so that it will not
be stepped on, tripped over or otherwise subjected to
damage orstress.
• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in
risk of fire, electric shock orelectrocution.
• When operating a charger outdoors, always provide
a dry location and use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electricshock.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the heavier the cord and
thus the greater its capacity. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size
to use depending on total length of all extension cords
plugged together, and nameplate ampere rating. If in
doubt, use the next heaviergauge.
