• The charger and battery pack are specifically designed to work
together. DO NOT attempt to charge the battery pack with any
chargers other than the ones in this manual.
• Do not expose charger to rain or snow.
• These chargers are not intended for any uses other than charging
D Walt rechargeable batteries. Any other uses may result in risk of fire,
E
electric shock or electrocution.
• To reduce risk of damage to electric plug and cord, pull by plug rather
than cord when disconnecting charger.
• Make sure cord is located so that it will not be stepped on, tripped over,
or otherwise subjected to damage or stress.
• An extension cord should not be used unless absolutely necessary.
Use of improper extension cord could result in risk of fire, electric
shock, or electrocution.
• An extension cord must have adequate wire size (AWG or American
Wire Gauge) for safety. The smaller the gauge number of the wire, the
greater the capacity of the cable, that is 16 gauge has more capacity
than 18 gauge. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size.

• The charger is ventilated through slots in the top and the bottom of the
housing. Do not place any object on top of charger or place the charger
on a soft surface that might block the ventilation slots and result in
excessive internal heat. Place the charger in a position away from any
heat source.
• Do not operate charger with damaged cord or plug — have them
replaced immediately.

center.
• Do not disassemble charger; take it to an authorized service center
when service or repair is required. Incorrect reassembly may result in
a risk of electric shock, electrocution or fire.
• To reduce risk of electric shock, unplug charger from outlet before
attempting any cleaning. Removing the battery pack will not reduce
this risk.
• NEVER attempt to connect 2 chargers together.
• DO NOT store or use the tool and battery pack in locations where the
temperature may reach or exceed 105°F (such as outside sheds or
metal buildings in summer).
• The charger is designed to operate on standard household electrical
power (120 Volts). Do not attempt to use it on any other voltage!

• 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.
• A small leakage of liquid from the battery pack cells may occur under
extreme usage or temperature conditions. This does not indicate a
failure. However, if the outer seal is broken and this leakage gets on
your skin:

b. Neutralize with a mild acid such as lemon juice or vinegar.
c. If battery liquid gets into your eyes, flush them with clean water for
a minimum of 10 minutes and seek immediate medical attention.
(Medical note: The liquid is 25-35% solution of potassium hydroxide.)
