NOTE: Your DW902 worklight operates on a 9.6V power pack. Your 
DW904 worklight operates on a 12V battery pack. Your DW906 worklight 
operates on a 14.4V power pack. Your DW908 worklight operates on a 
18V power pack. Power packs are sold separately.
  WARNING: To reduce the risk of injury, read the instruction manual.
General Power Tool Safety Warnings
 WARNING! Read all safety warnings and all instructions. 
Failure to follow the warnings and instructions may result in electric 
shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS 
FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated 
(corded) power tool or battery-operated (cordless) power tool.
Safety Rules for Worklights
WARNING: DO NOT OPERATE WORKLIGHT OR CHARGER NEAR 
FLAMMABLE LIQUIDS OR IN GASEOUS OR EXPLOSIVE ATMOSPHERES. 
INTERNAL SPARKS MAY IGNITE FUMES. Do not expose worklight or charger 
to rain or damp areas.
WARNING: Lens and bulb become hot during use.
•  During or immediately after use, don’t lay worklight flat on lens surface.
•  Don’t touch lens surface when bulb is lit or immediately after use.
•  Handle worklight with care around any flammable surface.
•  If bulb has been lit, let worklight cool for several minutes before changing 
bulb. 
Important Safety Instructions for All 
Battery Chargers
•  Before using charger, read all instructions and cautionary markings on 
charger, battery pack, and product using battery pack.
DANGER: Electrocution hazard. 120 volts are present at charging terminals. 
Do not probe with conductive objects. Electric shock or electrocution may 
result.
DANGER:  Electrocution hazard. 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 center for recycling.
  DO NOT attempt to charge the battery pack with any chargers 
other than the ones in this manual. The charger and batter y pack are 
specifically designed to work together. 
•  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.
  Two wire cords can be used with 2 or 3 wire extension cords. Only round 
jacketed extension cords should be used, and we recommend that they be 
listed by Underwriters Laboratories (U.L.) (C.S.A. in Canada.) The letters WA 
on the cord jacket indicate that the cord is suitable for outdoor use.
•  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 smaller the gauge number, the heavier the cord.

•  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.
•  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.
•  Do not store or use the tool and battery pack in locations where 
the temperature may reach or exceed 105°F (40˚C) (such as outside 
sheds or metal buildings in summer).
•  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.
Important Safety Instructions for All 
Battery Packs
SPECIFIC SAFETY INSTRUCTIONS FOR NICKEL CADMIUM (NiCd) OR 
NICKEL METAL HYDRIDE (NiMH)
•  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.
•  A small leakage of liquid from the battery pack cells may occur 
under extreme usage or temperature conditions. This does not 
indicate a failure. 
 
However, if the outer seal is broken:
a.  and the battery liquid gets on your skin, immediately wash with soap and 
water for several minutes.
b.  and the battery liquid gets into your eyes, flush them with clean water 
for a minimum of 10 minutes and seek immediate medical attention. 
(Medical note: The liquid is 25-35% solution of potassium hydroxide.)
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. Toxic 
fumes and materials are created when lithium ion battery packs are burned.
•  If battery contents come into contact with the skin, immediately 
wash area with mild soap and water. If battery liquid gets into the eye, 
rinse water over the open eye for 15 minutes or until irritation ceases. If 
medical attention is needed, the battery electrolyte is composed of a mixture 
of liquid organic carbonates and lithium salts.
•  Contents of opened battery cells may cause respiratory irritation. 
Provide fresh air. If symptoms persists, seek medical attention.
WARNING:  Burn hazard. Battery liquid may be flammable if exposed to 
spark or flame. 
NOTE:  Battery storage and carrying caps are provided for use
whenever the battery is out of the tool or charger. Remove cap 
before placing battery in charger or tool.
WARNING:  Fire hazard. Do not store or carry battery so that metal 
objects can contact exposed battery terminals. For example, do not place 
battery in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with 
loose nails, screws, keys, etc. without battery cap. Transporting batteries 
can possibly cause fires if the battery terminals inadvertently come in 
contact with conductive materials such as keys, coins, hand tools and 
the like.
 The US Department of Transportation Hazardous Material Regulations 
(HMR) actually prohibit transporting batteries in commerce or on airplanes (i.e., 
packed in suitcases and carry-on luggage) UNLESS they are properly protected 
from short circuits. So when transporting individual batteries, make sure that
