• 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 240V household electrical
power. Do not attempt to use it on any other voltage. This does not apply to the
vehicular charger.
• We recommend the use of a residual current device with a rated residual
current of 30 mA or less .
Using Automatic Tune-Up™ Mode
The automatic Tune-Up™ Mode equalizes or balances the individual cells in the
battery pack allowing it to function at peak capacity. Battery packs should be tuned up
weekly or after 10 charge/discharge cycles or whenever the pack no longer delivers
the same amount of work. To use the automatic Tune-Up™, place the battery pack
in the charger and leave it for at least 8 hours. The charger will cycle through the
following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has
started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and
will no longer blink. This indicates that the pack is fully charged and can be used
at this time.
3. If the pack is left in the charger after the initial 1-hour charge, the charger will
begin the Automatic Tune-Up mode. This mode continues up to 8 hours or until
the individual cells in the battery pack are equalized. The battery pack is ready for
use and can be removed at any time during the Tune-Up mode.
4. Once the Automatic Tune Up mode is complete, the charger will begin a
maintenance charge; the red indicator will remain lit.

at charging terminals. Do not probe with conductive
objects. Electric shock or electrocution may result.
1. Plug the charger into an appropriate outlet before
inserting battery pack.
2. Insert the battery pack into the charger, as shown in
Figure 1, making sure the pack is fully seated. The
red (charging) light will blink continuously indicating
that the charging process has started.
3. The completion of charge will be indicated by the red
light remaining ON continuously. The pack is fully
charged and may be used at this time or left in the
charger.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert
battery pack into the charger. If the problem persists, try a different battery pack to
determine if the charger is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to a service center or other collection site for recycling.
If the new battery pack elicits the same trouble indication as the original, have the charger
tested at an authorized service center.
