to use depending on cord length and nameplate ampere rating. If in doubt, use the
next heavier gage. The smaller the gage number, the heavier the cord.

IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY CHARGERS
SAVE THESE INSTRUCTIONS:
This manual contains important safety instructions for
battery chargers.
WARNING:
Before using charger, read all instructions and cautionary markings on
charger, battery pack, and product using battery pack.
•
Shock hazard.
Do not allow any liquid to get inside charger.
•
Burn hazard.
To reduce the risk of injury, charge only designated
BLACK+DECKER
batteries. Other types of batteries may burst causing personal injury and damage.
• Under certain conditions, with the charger plugged in to the power supply, 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 designated
BLACK+DECKER rechargeable batteries.
Any other uses 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 (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.
•
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.
•
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 household electrical power (120
Volts). Do not attempt to use it on any other voltage.
