Maintenance

The switch must be in the RUN position.
• To start manually, firmly grasp the recoil handle and pull slowly
until increased resistance is felt. Pull rapidly up and away to
start engine. Then follow the same choke sequence listed
above.
• When the engine starts, slide choke knob to "1/2 Choke"
position until the engine runs smoothly and then fully in to the
"Run" position. If engine falters, slide 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.
IMPORTANT: Do not overload the generator. Also, do not overload
individual panel receptacles. These outlets are protected against
overload with push-to-reset-type circuit breakers. If amperage
rating of any circuit breaker is exceeded, that breaker opens and
electrical output to that receptacle is lost. Read "Don't Overload the
Generator" carefully.

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.
• MoveRun/Stop switch to "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. If the engine shuts down by itself and the fuel tank has
enough gasoline, check engine oil level.
2.10.1 INITIAL START-UP
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.
2.10.2 SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the engine
shuts down.
2.10.3 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.

3.3 GENERAL RECOMMENDATIONS

The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value
from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenance section of this manual should
be made at least once each season. Follow the requirements in the
"Maintenance Schedule".
