Important Safety Instructions for All
Battery Packs
When ordering replacement battery packs, be sure
to include catalogue number andvoltage.
The battery pack is not fully charged out of the
carton. Before using the battery pack and charger,
read the safety instructions below. Then follow
charging proceduresoutlined.
READ ALL INSTRUCTIONS
• Do not charge or use battery in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Inserting
or removing the battery from the charger may
ignite the dust orfumes.
• Never force battery pack into charger. Do
not modify battery pack in any way to fit into
a non-compatible charger as battery pack
may rupture causing serious personalinjury.
• Charge the battery packs only in
DeWALTchargers.
• DO NOT splash or immerse in water or
otherliquids.
• Do not store or use the tool and battery
pack in locations where the temperature
may reach or exceed 40 ˚C (105 ˚F) (such as
outside sheds or metal buildings in summer).
WARNING: Never attempt to open the
battery pack for any reason. If battery
pack case is cracked or damaged,
do not insert into charger. Do not
crush, drop or damage battery pack.
Do not use a battery pack or charger
that has received a sharp blow, been
dropped, run over or damaged in any
way (i.e., pierced with a nail, hit with a
hammer, stepped on). Electric shock
or electrocution may result. Damaged
battery packs should be returned to
service centre forrecycling.
CAUTION: When not in use, place
tool on its side on a stable surface
where it will not cause a tripping
or falling hazard. Some tools with
large battery packs will stand upright
on the battery pack but may be easily
knockedover.
SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION
(Li-Ion)
• Do not incinerate the battery pack even if it
is severely damaged or is completely worn
out. The battery pack can explode in a fire.
continuously, and it may be removed and used at this
time or left in thecharger.
NOTE: To remove the battery pack, some chargers require
the battery pack release button to bepressed.
Refer to the indicators below for the charge status of the
batterypack.

Hot/Cold Pack Delay*
* The red light will continue to blink, but a yellow indicator
light will be illuminated during this operation. Once the
battery pack has reached an appropriate temperature, the
yellow light will turn off and the charger will resume the
chargingprocedure.
The compatible charger(s) will not charge a faulty battery
pack. The charger will indicate faulty battery by refusing
tolight.
NOTE: This could also mean a problem with acharger.
If the charger indicates a problem, take the charger and
battery pack to be tested at an authorised servicecentre.
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.
A cold battery pack will charge at about half the rate
of a warm battery pack. The battery pack will charge
at that slower rate throughout the entire charging
cycle and will not return to maximum charge rate
even if the batterywarms.
LITHIUM ION BATTERY PACKS ONLY
XR Li-Ion tools 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.
