DeWalt DCBL720 Instruction Manual page 7

• DO NOT attempt to charge the battery pack with any
chargers other than the ones in this manual. The charger and
battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than
charging D WAlT rechargeable batteries. Any other uses may
e
result in risk of fire, electric shock or electrocution.
• Do not expose the charger to rain or snow.
• 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 greater the capacity of the cable, that is, 16 gauge
has more capacity than 18 gauge. An undersized cord will cause a
drop in line voltage resulting in loss of power and overheating. 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 following table shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use the next heavier
gauge. The lower the gauge number, the heavier the cord.

• Do not place any object on top of the 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. The charger is ventilated
through slots in the top and the bottom of the housing.
• Do not operate the charger with a damaged cord or plug.
• Do not operate the charger if it has received a sharp blow,
been dropped or otherwise damaged in any way. Take it to an
authorized service center.
• Do not disassemble the 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.
• Disconnect the charger from the outlet before attempting
any cleaning. This will reduce the risk of electric shock.
Removing the battery pack will not reduce this risk.
• NEvER attempt to connect 2 chargers together.
• The charger is designed to operate on standard 120v
household electrical power. Do not attempt to use it on any
other voltage. This does not apply to the vehicular charger.
