Important Safety Instructions for Battery Chargers

SAVE THESE INSTRUCTIONS: This manual contains important safety instructions
for battery chargers.
• Before using charger, read all instructions and cautionary markings on charger,
battery pack, and product using battery pack.
DANGER: Electrocution Hazard. 240 volts 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
cadmium rechargeable batteries. Other types of batteries may burst 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
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.
For Cable length (m): 7.5
Use Cable with minimum rating (Amperes)

• 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
(240 Volts). Do not attempt to use it on any other voltage. This does not apply
to the vehicular charger.
