DeWalt DWC709 Instruction Manual page 35

• Before using charger, read all instructions and cautionary markings
on charger, battery pack, and product using battery pack.
DANGER: Electrocution hazard. 120V and 220V are present at
charging terminals. Do not probe with conductive objects. Electric
shock or electrocution may result.
WARNING: Shock hazard. Do not allow any liquid to get inside
charger. Electric shock may result.
CAUTION: Burn hazard. To reduce the risk of injury, charge only
D WALT rechargeable batteries. Other types of batteries may burst
E
causing personal injury and damage.
CAUTION: Under certain conditions, with the charger plugged
in to the power supply, the exposed charging contacts inside the
charger can be shorted by foreign material. Foreign materials of a
conductive nature such as, but not limited to, steel wool, aluminum
foil or any buildup of metallic particles should be kept away from
charger cavities. Always unplug the charger from the power supply
when there is no battery pack in the cavity. Unplug charger before
attempting to clean.
• 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
E
may result in risk of fire, electric shock or electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• Make sure that 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.
• An extension cord must have adequate wire size for safety.
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 smaller the gauge number, the heavier the cord.

12–16A 2.5
• 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. The charger is ventilated
through slots in the top and the bottom of the housing.
• Do not operate charger with damaged cord or plug — have
them replaced immediately.
• Do not operate 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 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.
