To turn the idle control feature on, turn on the idle control switch. Using this feature is recom-
mended while the generator is running to minimize fuel consumption. To avoid extended
engine warm-up periods, place the switch in the off position when starting the engine and until
the engine reaches operating temperature.
OPERATION
Starting Generator — Recoil Start
WARNING: Before starting the generator, be sure that you read and understand all the
safety and operating instructions in this manual.
1. Disconnect all electrical loads from the generator and place the main circuit breaker in the
off position.
2. Turn the idle control switch (figure 13H) off.
NOTE: The D
WALT models DG4300, DG6000, DG6000E, DG7000 and DG7000E have the
E
idle control feature. Model DG2900 does not have this feature.
3. Open the fuel valve by turning the petcock clockwise to the vertical position as shown in
figure 15.
4. If the engine is cold, pull the choke lever out to the closed position shown in figure 16. If
the engine is hot, set choke to open position shown in figure 17.
5. Turn engine switch (figure 13A) on.
6. Pull the starter grip slowly until you feel compression then pull briskly.
NOTE: Do not allow the starter grip to snap back. Return it slowly by hand.
NOTE: If the oil level in the engine is low, the engine will not start. If the engine does not start,
check the oil level and add oil as needed.
NOTE: To ensure maximum oil lubrication, place the generator on a level surface.
7. As the engine warms up, move the choke lever to the open position shown in figure 17.
8. Allow the engine to warm up for a few minutes. Then place the main breaker (figure 13B)
in the on position. Attach electrical loads.
Starting the Generator — Electric Start
WARNING: Before starting the generator, be sure you read and understand all the safety
and operating instructions in this manual.
1. Follow steps 1 through 5 of the recoil start section.
2. Turn starter switch to the start position. See Figure 18.
3. Hold the switch in the start position until the engine starts.
NOTE: Do not hold the switch in the start position for more than
5 seconds. If the engine does not start, wait 10 seconds before re-
trying. Failure to follow these instructions may result in damage to
the starter motor due to overheating.
4. When the engine starts, release the switch, allowing it to return
to the run position.
NOTE: Do not turn the switch to the start position while the generator is running.
5. As the engine warms up, move the choke lever to the open position as shown in figure 17.
6. Allow the engine to warm up for a few minutes before placing the main breaker (figure 13B)
in the on (closed) position. Attach electrical loads.

Stopping the Generator
To stop the engine in an emergency, move the engine switch to the off position. For electric
start models (DG6000E and DG7000E) turn the engine switch to the stop position.
To Stop the Generator in Normal Use:
1. Turn off and disconnect all electrical loads attached to
the generator.
2. Turn the engine switch off. For electric start models
(DG6000E and DG7000E), turn the engine switch to
stop.
3. Close the fuel valve by turning petcock counterclock-
wise to the horizontal position shown in figure 19.
Engine Speed
Generators require a fixed engine speed to maintain the
correct voltage. Engine speed is controlled by the governor
which automatically adjusts to varying loads on the engine
to maintain a constant speed of 3600-3700 rpm.
NOTE: Do not adjust the governor setting of this generator. It has been set at the factory for
optimum performance. Tampering may cause damage to the generator and voids the warran-
ty. The governor may only be adjusted by an authorized service center.

High Altitude Operating
At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will
decrease and fuel consumption will increase. A very rich mixture will also foul the spark plug
and cause hard starting.
High altitude performance can be improved by specific modifications to the carburetor. If you
always operate your engine at altitudes above 1,800 meters (6,000 feet), have your authorized
service center perform a carburetor modification.
Even with a carburetor modification, engine horsepower will decrease about 3.5% for each 300
meter (1,000 foot) increase in altitude. The effect of altitude on horsepower will be greater than
this if no carburetor modification is made. A decrease in engine horsepower will decrease the
power output of the generator.
NOTE: When the carburetor has been modified for high altitude operation, the air-fuel mixture
FIGURE 18: ELECTRIC
will be too lean for low altitude use. If the generator is used at low altitudes after a carburetor

modification, the carburetor may cause the engine to overheat and result in serious engine
damage. For use at low altitudes, have your authorized service center return the carburetor to
original factory specifications.
