DeWalt DCST991 - Important Charging Notes

ENGLISH

and instructions may result in electric shock, fire
and/or serious injury.
• 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
DeWALT
rechargeable batteries.
Any other uses may result in risk of fire, electric shock
orelectrocution.
• Do not expose the charger to rain orsnow.
• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.
• Make sure that the 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.
• When operating a charger outdoors, always provide
a dry location.
• If use of an extension cord is absolutely necessary
outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk
of electricshock.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than 18
gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using
more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier thecord.

• Do not place any object on top of the 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 the charger with a damaged cord
orplug.
• Do not operate the 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 the 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
120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicularcharger.

WARNING: Shock hazard. Do not allow
any liquid to get inside the charger. Electric shock
mayresult.

WARNING: Burn hazard. Do not
submerge the battery pack in any liquid or allow any
liquid to enter the battery pack. Never attempt to open
the battery pack for any reason. If the plastic housing
of the battery pack breaks or cracks, return to a service
center for recycling.

CAUTION: Burn hazard. To reduce the risk
of injury, charge only
DeWALT
rechargeable battery
packs. Other types of batteries may overheat and burst
resulting in personal injury and propertydamage.
NOTICE: Under certain conditions, with the
charger plugged into the power supply, the charger
can be shorted by foreign material. Foreign materials
of a conductive nature, such as, but not limited to,
grinding dust, metal chips, steel wool, aluminum
foil or any buildup of metallic particles should be
kept away from the charger cavities. Always unplug
the charger from the power supply when there is no
battery pack in the cavity. Unplug the charger before
attempting toclean.
Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect
the charger from the AC outlet before cleaning. Dirt
and grease may be removed from the exterior of the
charger using a cloth or soft non-metallic brush. Do
not use water or any cleaning solutions.
Important Charging Notes
1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature is
between 65°F and 75°F (18° – 24°C). DO NOT charge
the battery pack in an air temperature below +40°F
