Operation
IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank
during storage. Alcohol-blended fuels (called gasohol, ethanol
or methanol) can attract moisture, which leads to separation and
formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30 days or
longer. See the "Storage" section. Never use engine or carburetor
cleaner products in the fuel tank as permanent damage may
occur.
2.8 TO START THE ENGINE
Never start or stop engine with electrical devices

plugged into the receptacles AND devices turned on.
• Unplug all electrical loads from the unit's receptacles before
starting the engine.
• Make sure the unit is in a level position.
• Open the fuel shut-off valve (Figure 10).
• Pull engine CHOKE knob outward to "Full Choke" position
(Figure 11).

2.8.1 MANUAL (RECOIL) STARTING
• To start the generator, put the on/off switch in the ON position.
• Firmly grasp the recoil handle and pull slowly until increased
resistance is felt. Pull rapidly up and away to start engine.
• When the engine starts, push choke knob to "1/2 Choke"
position until the engine runs smoothly and then fully in to the
"Run" position. If engine falters, pull choke knob back out to
"1/2 Choke" position until the engine runs smoothly and then
to "Run" position.
If engine fires, but does not continue to run, pull choke knob
to "Full Choke" and repeat starting instructions.
2.8.2 ELECTRIC STARTING (XG7000E & XG8000E)
• To start the engine, press and hold the Start/Run/Stop switch in
the "Start" position. The engine will crank and attempt to start.
When the engine starts, release the switch to the run position.
• When the engine starts, push choke knob to "1/2 Choke"
position until the engine runs smoothly and then fully in to the
"Run" position. If engine falters, pull choke knob back out to
"1/2 Choke" position until the engine runs smoothly and then
to "Run" position.
• This generator is also equipped with a manual recoil starter
which may be used if the battery is discharged.
The engine Start/Run/Stop switch must be in the RUN
position when using the manual recoil starter.
2.9 STOPPING THE ENGINE
• Shut off all loads, then unplug the electrical loads from
generator panel receptacles. Never start or stop the engine with
electrical devices plugged in and turned on.
• Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
• Move Start/Run/Stop or On/Off switch to the "Off" position.
• Close fuel valve.
2.10 LOW OIL PRESSURE SHUTDOWN SYSTEM
The engine is equipped with a low oil pressure sensor that shuts
down the engine automatically when the oil pressure drops below
5 psi. A delay built into the low oil shutdown system allows oil
pressure to build during starting. The delay allows the engine to
run for about 10 seconds before sensing oil pressure. If the engine
shuts down by itself and the fuel tank has enough gasoline, check
engine oil level.
2.10.1 RESTARTING
If trying to restart the engine within 10 seconds after it shuts down,
the engine may NOT start. The system needs 5 to 10 seconds to
reset.
If the engine is restarted after such a shutdown and the low oil
pressure has not been corrected, the engine will run for about 10
seconds as described above and then stop.
