• Move engine CHOKE knob to “Full Choke” position.
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. 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.
