• Move engine CHOKE knob to “Full Choke” position.
Figure 17 - Full Choke Position
• To start 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, move choke knob to “1/2 Choke”
position until the engine runs smoothly and then to “Run”
position. If engine falters, move choke knob 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, move choke
lever to “Full Choke” and repeat starting instructions.
2.8 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.
• Turn “Off” the Idle Control switch (if on).
• Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
• Move Start/Run/Stop switch to “Off” position.
• Close fuel valve.
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” on page 9 carefully.
2.9 AUTOMATIC IDLE CONTROL
This feature is designed to greatly improve fuel economy. When
this switch is turned “On,” the engine will only run at its normal
fast governed engine speed when electrical load is connected.
When the load is removed, the engine will run at a reduced speed
of 2100RPM. With the switch “Off,” the engine runs at the normal
fast engine speed all the time. Always have the switch OFF when
starting and stopping the engine.
2.10 COLD WEATHER OPERATION/ DE-ICER
Under certain weather conditions (temperatures below 40° F (4°
C) and a high dew point), the engine may experience icing of the
carburetor and/or the crankcase breather system. To eliminate
this problem, this generator engine is fitted with a winter/summer
valve. this directs hot air into the carburetor during cold weather
operation. Always make sure the winter/summer valve is in the
correct location relative to the weather conditions.
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
10 psi. If the engine shuts down by itself and the fuel tank has
enough gasoline, check engine oil level.
2.11.1 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.
2.11.2 SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the engine
shuts down.
2.11.3 RESTARTING
If you try 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 you do restart the engine after such a shutdown and have not
corrected the low oil pressure, the engine runs for about 10
seconds as described above and then stops.
