1. Plug the charger (11) into an appropriate outlet
before inserting battery pack.
2. Insert the battery pack into the charger. 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.
NOTE: To ensure maximum performance and life of
NiCd, NiMH and Li-Ion batteries, charge the battery
for a minimum of 10 hours before first use.

Automatic Refresh
The automatic refresh mode will equalise or balance
the individual cells in the battery pack at its peak
capacity. Battery packs should be refreshed weekly
or whenever the pack no longer delivers the same
amount of work.
To refresh your battery pack, place the battery in the
charger as usual. Leave the battery pack for at least
10 hours in the charger.
Hot/Cold Pack Delay
When the charger detects a battery that is too hot
or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.
LI-ION BATTERY PACKS ONLY
Li-Ion batteries are designed with an Electronic
Protection System that will protect the battery against
overloading, overheating or deep discharge.
The tool will automatically turn off if the Electronic
Protection System engages. If this occurs, place the
Li-Ion battery on the charger until it is fully charged.
