Using the DCB500 Corded Power Supply
The
DeWALT
corded power supply is designed to
provide power for
DeWALT
2x 54 V FLEXVOLT™ cordless
tools. Insert the corded power supply into the mitre
saw battery slot (refer to Installing and Removing the
Corded Power Supply and Figure D) and plug the
power supply into an AC outlet. The power supply will
act as the power source to the tool. Your
DeWALT
corded power supply should only be used with
standard 230V household electric power supply. UK 115V units should be plugged into a
115Vtransformer.
The corded power supply is suitable for use with double insulated 2x54V AC tools. The EU
model of DCB500 has no groundcontact.
Your
DeWALT
corded power supply should only be used with a power supply corresponding
to the voltage on the rating plate of the DCB500 and not with DC power sources. Please
check that the current rating of the tool is smaller or equal to the current rating of the power
supplyadapter.
Additional Specific Usage Instructions
The corded power supply may become warm to the touch during use. This is a normal
condition and does not indicate aproblem.
IMPORTANT. The power supply is not user serviceable. There are no user serviceable parts
inside the power supply.
Important Safety Instructions for All Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important safety and operating
instructions for compatible battery chargers (refer to TechnicalData).
• Before using charger, read all instructions and cautionary markings on charger, battery pack,
and product using batterypack.

WARNING: Shock hazard. Do not allow any liquid to get inside charger. Electric shock
mayresult.

CAUTION: Burn hazard. To reduce the risk of injury, charge only
DeWALT
rechargeable
batteries. Other types of batteries may burst causing personal injury anddamage.

CAUTION: Children should be supervised to ensure that they do not play with
theappliance.
NOTICE: Under certain conditions, with the charger plugged into the power supply, the
exposed charging contacts inside the charger can be shorted by foreign material. Foreign
materials of a conductive nature such as, but not limited to, steel wool, aluminum foil
or any buildup of metallic particles should be kept away from charger cavities. Always
unplug the charger from the power supply when there is no battery pack in the cavity.
Unplug charger before attempting to clean
• 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 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 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.
• In case of damaged power supply cord the supply cord must be replaced immediately by the
manufacturer, its service agent or similar qualified person to prevent anyhazard.
• 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 230V household electrical power. Do
not attempt to use it on any other voltage. This does not apply to the vehicularcharger.
Charging a Battery (Fig. B)
1. Plug the charger into an appropriate outlet before inserting batterypack.
2. Insert the battery pack
21
into the charger, making sure the battery pack is fully seated
in the charger. The red (charging) light will blink repeatedly indicating that the charging
process hasstarted.
3. The completion of charge will be indicated by the red light remaining ON continuously.
The battery pack is fully charged and may be used at this time or left in the charger. To
remove the battery pack from the charger, push the battery release button
31
on the
batterypack.
NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the
battery pack fully before firstuse.
Charger Operation
Refer to the indicators below for the charge status of the batterypack.
Charge Indicators
Charging
Fully Charged
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 pack that is too hot or too cold, it automatically starts a
Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate
temperature. The charger then automatically switches to the pack charging mode. This feature
ensures maximum battery packlife.
A cold battery pack will charge at a slower rate than 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 packwarms.
The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The
fan will turn on automatically when the battery pack needs to be cooled. Never operate the
charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit
foreign objects to enter the interior of thecharger.
Electronic Protection System
XR Li-Ion tools are designed with an Electronic Protection System that will protect the battery
pack against overloading, overheating or deepdischarge.
The tool will automatically turn off if the Electronic Protection System engages. If this occurs,
place the lithium-ion battery pack on the charger until it is fullycharged.
Wall Mounting
These chargers are designed to be wall mountable or to sit upright on a table or work surface.
If wall mounting, locate the charger within reach of an electrical outlet, and away from a
corner or other obstructions which may impede air flow. Use the back of the charger as a
template for the location of the mounting screws on the wall. Mount the charger securely
using drywall screws (purchased separately) at least 25.4mm long with a screw head diameter
of 7–9mm, screwed into wood to an optimal depth leaving approximately 5.5mm of the
screw exposed. Align the slots on the back of the charger with the exposed screws and fully
engage them in theslots.
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. Never let any liquid
get inside the tool; never immerse any part of the tool into aliquid.
Battery Packs
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.
