SAFETY INSTRUCTIONS FOR GENERATORS
SAVE THESE INSTRUCTIONS FOR FUTURE USE
WARNING! Read and understand all instructions. Familiarity and proper training are
required for the safe operation of generators. A generator operated improperly or by untrained
personnel can be dangerous. Become familiar with all of the generator's controls, output
receptacles and connections. Know how to stop generator in case of emergency. Failure to fol-
low all instructions listed below may result in electrical shock, property damage,and/or serious
personal injury or death. This manual contains IMPORTANT SAFETY INSTRUCTIONS for
models DG2900, DG4300, DG6000, DG7000, DG60000E and DG7000E. It is important to
SAVE THESE INSTRUCTIONS.
Do not operate the generator unless it is fully assembled.
NOTE: All D WALT generators come with a Honda engine owner's manual. The Honda man-
E
ual overrides this manual on all engine topics. Honda engine manuals are available through
D WALT at 1-800-4-D WALT.

WARNING: This product contains chemicals known to the state of California to cause
cancer, birth defects or other reproductive harm.
WARNING! CARBON MONOXIDE HAZARDS
Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing
exhaust can cause loss of consciousness and may lead to death. If you run the generator in
an area that is confined, or even partially enclosed, the air you breathe could contain a dan-
gerous amount of exhaust gas. To keep exhaust from building up, provide adequate ventila-
tion. Do not operate the generator in a room, cave, or tunnel unless professionally installed
exhaust hoses are used.
WARNING! ELECTRIC SHOCK HAZARDS
The generator produces enough electrical power to cause serious shock or electrocution if
misused. Using a generator or an electrical device in wet conditions — near water, on wet
grass, in damp areas, in rain or snow — could result in electrocution. Keep the generator dry
at all times. This generator is not designed to be stored outdoors unprotected from the weath-
er. Moisture or ice can cause a malfunction or short in electrical components, which could
result in electrocution. Test GFCI outlets and accessories before each use. Check all electri-
cal components on the control panel before each use.
Do not connect this generator to any building's electrical system unless a licensed electrician
has installed an isolation switch. Failure to do so can result in property damage or death.
WARNING! FIRE & BURN HAZARDS
The exhaust system gets hot enough to ignite some materials. Keep generator at least 1 meter
(3 feet) away from buildings and other equipment during or immediately after operation. Never
enclose generator in any structure. Keep all flammable materials away from the generator.
The muffler becomes very hot during operation and remains hot for some time after the engine
stops. Do not touch the muffler while the engine is running or hot. Allow the engine and the
muffler to cool before storing. See storing instructions on page 2 of this manual.
Gasoline is highly flammable and poisonous. Always stop the engine and allow the muffler to
cool before refueling. Never refuel while smoking or in the vicinity of an open flame or sparks.
Never smoke near the generator. Always check for spilled fuel or fuel leaks. Make sure that
any spilled fuel has been wiped up before starting the generator. When operating or trans-
porting the generator, be sure that it is kept upright. If the unit tilts, fuel may leak from the car-
buretor or fuel tank.

GROUNDING THE GENERATOR

Grounding the generator helps prevent electric shock from a
ground fault condition. To ground the generator you will need
a ground wire and grounding stake. These are not supplied
with the generator. The ground wire should be a #8, strand-
ed-copper wire. The grounding point should be copper or
brass.
1. Locate the ground plug below the generator control panel
(shown in figure 1).
2. Attach a ground wire to the ground plug.
3. Drive the grounding point into the ground.
4. Attach the ground wire to the grounding point.
The generator should be grounded to a good ground source in compliance with National
Electric Codes standards and local regulations. In some areas, generators are required to be
registered with local utility companies.
power tools.
gasses for the grounding point.

GROUND FAULT CIRCUIT INTERRUPT (GFCI)

On D
DG7000E), all 20 Amp receptacles are protected by a ground fault circuit interrupt (GFCI). The
20A twist lock receptacles are linked to the GFCI duplex receptacles, therefore providing GFCI
protection. The GFCI shuts off the power to the receptacle when it senses small imbalances
caused by current leakage to the ground.
used.
TO TEST A GFCI:
Start the generator. Turn the auto idle switch (figure 13H) off. (See page 4 for
control panel layout information.) Push in the TEST button (A) on the recep-
tacle. The RESET button (B) will pop out. Power is now off at the receptacle.
If the RESET button does not pop out, the GFCI is not working. Do not run
generator until the problem can be corrected. To restore power to receptacle,
push the RESET button in. If the RESET button pops out during operation,
stop the generator and check the generator and equipment for defects.

USE OF EXTENSION CORDS

Only use grounded extension cords that are rated for outdoor use and equip-
ment with a third-wire ground. If using a 30A twist-locking receptacle, you must
connect through a GFCI Protected spider box or use an in-line GFCI adapter.
The 20A twist lock receptacle is already protected by GFCI, therefore addi-
tional GFCI protection in not necessary.
When a long extension cord is used to connect an appliance or tool to the generator, a volt-
age drop occurs. The longer the cord, the greater the voltage drop. This results in less voltage
being supplied to the appliance or tool and increases the amount of current (amp) draw or
reduces performance. A heavier cord with a larger wire size will reduce the voltage drop. Be
sure to choose a cord that will supply enough voltage to operate your tool or appliance. The
