features. The DE0245 charger is fitted with a manual tune-up mode whereas the
DE0246 is fitted with an automatic tune-up mode. Also, the DE0246 charger is fitted
with a cooling fan to assist the cooling of the battery cells when the battery pack is
fitted to the charger.
Your charger is designed to use standard 240 volt AC, 50 Hz power. Do not use DC or
any other voltage. Charging time is approximately one hour.
Charging Procedure (DE0245 & DE0246)
The DE0246 charger is fitted with an internal cooling fan that provides rapid cooling of the
cells in the battery pack. The fan operation is automatic and will operate for a short time
when the charger is initially plugged in and turned on. The fan will also operate while the
charging process is underway when a battery is inserted.
This feature is of great benefit where the battery pack has become hot during heavy
applications in the tool and the pack is inserted to the charger to both cool the pack
and either partially or fully charge the pack.
To fully optimise both the life and performance of the battery pack, remove the
battery pack from the tool as soon as possible and insert into the charger so as to
allow the internal fan to cool the individual cells.
WARNING: On the DE0246, the fan may blow debris from vent area at any time.
Keep your face and eyes well above the outlet vent area. Depending on the
environment where the charger is being used it may be necessary to wear eye
protection.
1. Plug the charger into an appropriate outlet.
(On the DE0246 the fan will operate initially for up to 30 sec)
2. Insert the battery pack into the charger (refer figure B1). Be sure the pack is fully
seated in the charger. The red (charging) light will blink continuously indicating
that the charging process has started. On the DE0246 the fan will operate and
remain "On" during the main charging cycle.
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.
Using Tune-Up mode
Using Tune-Up mode will equalise 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 15 charge/discharge cycles or whenever the pack
no longer delivers the same amount of work.
Both the DE0245 and the DE0246 are fitted with a Tune-Up mode feature.
The DE0245 charger is fitted with a manual Tune-Up mode cycle which is initiated by
the operator pushing the small button at the front of the charger marked "Tune-Up
Mode."
The DE0246 is fitted with an auto Tune-Up mode cycle where at the completion of
the normal charging cycle if the battery is left in the charger, the tune up mode cycle
begins.
For DE0245 Manual Tune-Up
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 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. Then normal
charge cycle will commence. To tune up your battery pack, place the battery in
the charger as usual. The red light will blink continuously indicating the charge
cycle has started.
For DE0246 Auto Tune-Up
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.
When the battery is fully charged the red light will remain on, and the tune up cycle
will begin. For the full tune up process, leave the battery pack in the charger for a
further 7 - 8 hours. Please note that the battery pack can be used during the tune up
cycle but when the battery is replaced in the charger, the charging cycle will start
again followed by the tune up cycle where the battery should stay for the full 7 - 8
hours.
During the tune up cycle the red indicator light will remain "ON" continuously.
CHARGE INDICATORS
HOT/ COLD PACK DELAY:
When the charger detects a battery that is excessively hot or excessively cold, it
automatically starts a Hot/Cold Pack Delay, suspending charging until the battery
temperature has normalised. After this happens, the charger automatically switches
to the Pack Charging mode. This feature ensures maximum battery life. The red light
