2.9.1 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.
NOTE:
If engine fires, but does not continue to run, pull choke knob
to “Full Choke” and repeat starting instructions.
2.9.2 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.
NOTE:
The switch must be in the RUN position. Use one of the
generator’s receptacle outlets along with the included battery
charger to charge the battery while the generator is running.
2.10 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.
2.11 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.
2.11.1 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.
2.12 CHARGING THE BATTERY (XG7000E & XG8000E)

Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron and
rubber gloves when working around a battery.
Battery electrolyte fluid is an extremely
corrosive sulfuric acid solution that can cause
severe burns. If spill occurs flush area with
clear water immediately.
Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.
