• Make sure that 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.
• 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. The charger
is ventilated through slots in the top and the
bottom of the housing.
• 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 authorised
service centre.
• Do not disassemble charger; take it to an
authorised service centre 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 230V household electrical power.
Do not attempt to use it on any other voltage.
This does not apply to the vehicular charger.

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.
Important Safety Instructions for All
