DeWalt DCS310 Instruction Manual page 8

• 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 two chargers together.
• The charger is designed to operate on standard 120V
household electrical power. Do not attempt to use # on any
other voltage. This does not apply to the vehicular charger.
Chargers
Your tool uses a DEWALT charger. Be sure to read all safety
instructions before using your charger. Consult the chart on the back
cover of this manual for compatibility of chargers and battery packs.
Charging Procedure (Fig. 1)
1. Plug the charger into an appropriate outlet before inserting battery
pack.
2. Insert the battery pack (J) into the charger, as shown in Figure 1,
making sure the pack is fully seated in charger. The red (charging)
light will blink continuously indicating that the charging process
has started.
FIG. 1
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.
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.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the
charger detects a battery that is hot, it automatically starts a Hot Pack
Delay, suspending charging until the battery has cooled. After the
battery has cooled, the charger automatically switches to the Pack
Charging mode. This feature ensures maximum battery life. The red
light flashes long, then short while in the Hot/Cold Pack Delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge
indicator showing Pack Charged.
WEAK BA'R'ERY PACKS: Weak batteries will continue to function
but should not be expected to perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty
battery pack. The charger will indicate faulty battery pack by refusing
to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
