DeWalt DC901 Instructions Manual page 37

• DO NOT attempt to charge the battery pack
with any chargers other than the ones in
this manual. The charger and battery pack are
specifically designed to work together.
• These chargers are not intended for any uses
other than charging D
E
batteries. Any other uses may result in risk of
fire, electric shock or electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when
disconnecting charger. This will reduce risk
of damage to electric plug and cord.
• 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 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.
• 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 230 V household electrical power.
Do not attempt to use it on any other voltage.
This does not apply to the vehicular charger.
SAVE THESE INSTRUCTIONS
Chargers
The DE9000 charger accepts 36 V Li-Ion batteries.
This charger requires no adjustment and is designed
to be as easy as possible to operate.
Charging Procedure (fi g. B)
WALT rechargeable
NOTE: To ensure maximum performance and life of
Li-Ion batteries, charge the battery pack fully before
first use.
Charging Process (fi g. B)
Refer to the table below for the state of charge of the
battery pack.
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.
DANGER: Electrocution hazard.
230 volts present at charging terminals.
Do not probe with conductive objects.
Danger of electric shock or electrocution.
1. Plug the charger (12) into an appropriate outlet
before inserting battery pack.
2. Insert the battery pack into the charger. The
charger is equipped with a three-light fuel gauge
(13) that will blink according to the state of
charge of the battery pack.
3. The completion of charge is indicated by the
three red lights remaining ON continuously. The
pack is fully charged and may be used at this
time or left on the charger.
