• 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 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.

WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric shock

may result.

WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any

liquid to enter the battery pack. Never attempt to open the battery pack for any reason. If the

plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

CAUTION: Burn hazard. To reduce the risk of injury, charge only D

battery packs. Other types of batteries may overheat and burst resulting in personal injury

and property damage.

NOTICE: Under certain conditions, with the charger plugged into the power supply, the

charger can be shorted by foreign material. Foreign materials of a conductive nature, such

as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil or any buildup

of metallic particles should be kept away from the charger cavities. Always unplug the

charger from the power supply when there is no battery pack in the cavity. Unplug the

charger before attempting to clean.

Charging a Battery (Fig. 3)

Plug the charger into an appropriate outlet before inserting battery pack.

FIG. 3

Insert the battery pack into the charger, making sure the battery pack is fully seated in the

charger. The red (charging) light will blink continuously indicating that the charging process

has started.

The completion of charge will be indicated by the red light remaining ON continuously. The

battery pack is fully charged and may be used at this time or left in the charger. To remove the

battery pack from the charger, push the battery release button on the battery pack.

NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the

battery pack fully before first use.
