fire, electric shock or electrocution.
• To reduce risk of damage to electric plug and cord, pull by plug rather
than cord when disconnecting charger.
• Make sure cord is located so that it will not be stepped on, tripped over,
or otherwise subjected to damage or stress.
• An extension cord should not be used unless 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.

• The charger is ventilated through slots in the top and the bottom of the
housing. 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.
• 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.
• To reduce risk of electric shock, unplug charger from outlet before
attempting any cleaning. 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 AC). Do not attempt to use it on any other voltage!
This does not apply to vehicular charger.
Chargers
Your battery can be charged in D
Chargers or Vehicular 12 volt charger. Be sure to read all safety
instructions before using your charger.
Consult chart on back cover for compatibility of chargers and battery
packs.
Using Tune-Up™ Mode
The Tune-up™ mode will equalize or balance the individual cells in
the battery pack at its peak capacity. This cycle takes up to 8 hours to
complete. Battery packs should be tuned up weekly or after 10 to 20
charge/discharge cycles or whenever the pack no longer delivers the
same amount of work.
1. To tune up your battery pack, place the battery in the charger as
usual. The red light will blink continuously indicating that the charge
cycle has started.
2. The Tune-up™ Button may be pressed at any time after the charge
has started. The red light will stop blinking momentarily, blink quickly
3 times, and then resume blinking continuously. The charger is
now giving your batteries a tune-up.
3. When the charge cycle has completed, the light will stay on
continuously. The pack is fully charged and may be used at this time
or left in the charger.
4. If you select Tune-up™ and then change your mind, remove the
battery from the charger. After 5 seconds, insert the battery into the
charger. The normal charge cycle will commence.
