RECEPTACLE THERMAL CIRCUIT BREAKERS @ @
The receptacle thermal circuit breakers protect the receptacles.
Overloading the generator will trip the thermal circuit breaker (U). If 1_,,3°A 2oA
a thermal circuit breaker moves to the tripped position as shown: _ (i'_)'J
1. Disconnect the electrical load from the receptacle.
2. Allow the circuit breaker to cool. TRIPPED RESET
3. Push the thermal circuit breaker to reset. If thermal circuit breaker will not reset, contact
a DEWALT factory service center or a DEWALT authorized service center.
NOTE: The 120/240V twist-locking receptacle does not have a thermal circuit breaker.
The receptacle is protected by the main breaker. High ambient temperatures can cause
thermal breakers to trip.
GFCl DUPLEX RECEPTACLES (120V)
All 20A convenience receptacles are GFCI (V) protected. The GFCI protects you against
hazardous electrical shock caused when your body becomes a path through which electricity
travels to the ground. This could happen when you touch a cord of an appliance that is "live"
through faulty mechanism, dampness or worn insulation, etc. The GFCI shuts off the power to
the receptacle when it senses small imbalances caused by current leakage to the ground.
t& CAUTION: Each GFCI should be tested for proper operation every time the generator is used,
see Test GFCI under Maintenance.
TWISTLOCK RECEPTACLES (120V)
NOTE: (DG4400B, DG6300B and DG7000B) The 20A and 30A twistlock receptacles are not
protected by the GFCI. Use a GFCI protected spider box or GFCI adapter to connect loads
to the 20A and 30A twistlock receptacles.
NOTE: (DG3000) The 20A twistlock receptacle is protected by the GFCI.
VOLTAGE SELECTOR SWITCH
DG4400B, DG6300B AND DG7000B
This switch (R) allows the generator to operate in either single voltage (120V) or dual voltage
(120/240V) mode. When placed in the 120V position it allows you to receive the full capacity
of the generator by using all the receptacles. When placed in the 120/240 position, you will
only be able to receive half the available watts when using the 120 volt receptacles and the
full available watts when using the 240V 4-prong twist-lock receptacle.
NOTE: Do not move the voltage selector switch (R) while powering electrical devices.
Disconnect all electrical loads before moving the switch. Failure to disconnect electrical loads
could damage the switch.
IDLE CONTROL SWITCH
DG4400B, DG6300B AND DG7000B
The idle control switch (P) automatically reduces engine speed after all electrical loads
attached to the generator have been turned off. The engine automatically returns to full speed
when an electrical load is turned back on. Using this feature is recommended while the gen-
erator is running to minimize fuel consumption.
To use the idle control feature:
1. Place the idle control switch (P) in the ON position. NOTE: The idle control switch must
be in the OFF position when starting the engine.
Using the idle control switch IS NOT recommend on large motors (refrigerators, freezers, etc)
or voltage sensitive electronic equipment (computers, televisions, etc). For these applica-
tions
2. Place the idle control switch in the OFF position.
LOW OIL PROTECTION
Low oil shutdown is a device designed to protect the engine from damage in the event the oil
level in the crankcase is low.
If while the engine is running, the oil gets low, it will automatically shut itself down and will not
restart until the oil is added. If the oil is low before start-up, the generator will not start until oil
is added.
NOTE: The low oil shutdown mechanism is very sensitive. You must fill the engine to the full
mark on the dipstick.
OPERATION
PreoStart Checklist (Fig. 2)
_, WARNING: Do not operate this unit until you read and understand this instruction manual and
the engine instruction manual for safe_ operation and maintenance instructions.
A CAUTION: Always check engine oil level before every start. Running engine low of oil or out
of oil could result in serious damage to the engine.
Follow the steps listed below before starting generator:
1. Check engine oil. Refer to the engine instruction manual for correct grade and quantity of
oil.
2. Check fuel level, fill as required. See Add Engine Oil and Fuel under Assembly.
3. Make sure generator is grounded in accordance with local requirements. See Grounding
the Generator under Assembly.
4. All electrical loads MUST be disconnected and main breaker (T) in the OFF position.
5. (DG4400B, DG6300B and DG7000B) The idle control switch (P) MUST be in the OFF
position.
CAUTION: Engine speed has been factory set to provide safe operation. Tampering with the
engine speed adjustment could result in overheating of attachments and could cause a fire.
Never attempt to "speed-up" the engine to obtain more performance. Both the output voltage
and frequency will be thrown out of standard by this practice, endangering attachments and
the user. Tampering may cause damage to the generator and voids the warranty.
ik CAUTION: Unplug any load from the generator before starting to prevent permanent dam-
age to any appliances.
6. Test the GFCI outlets (V), see Test GFCl under Maintenance.
Starting Generator _ Recoil Start (Fig. 1, 2)
WARNING: Do not operate this unit until you read and understand this instruction manual and
the engine instruction manual for safety, operation and maintenance instructions.
1. Disconnect all electrical loads from the generator and place the main
circuit breaker (T) in the OFF position.
2. (DG4400B, DG6300B and DG7000B) Place the idle control switch (P)
in the OFF position.
3. Turn the fuel shut-off valve (K) on the gas tank to the vertical (OPEN)
position as shown.
4. If the engine is cold, move the choke (J) to the CLOSED position shown.
If the engine is hot, move the choke to OPEN position.
OR
5. Turn engine switch (S) to the ON position.
6. Pull the starter grip (L) slowly until you feel compression then pull briskly.
