AT T ENTION
For gasoline restarts with hot engine in hot ambient temperature >86°F (30°C): Rotate the Multi-Switch to the
“START” position for only one pull of the recoil cord. If generator does not start after first pull, rotate the Multi-
Switch to the “RUN” position for the next three pulls. Too much choke leads to spark plug fouling and engine
flooding. This will cause the engine not to start.
14
STARTING UP THE GENERATOR
AT T ENTION
For gasoline starting in standard ambient temperature >59°F(15°C): Keep Multi-Switch in “START” position for
three pulls of the recoil cord. If generator does not start after three pulls, rotate the Multi-Switch to the “RUN”
position for the next three pulls. Too much choke leads to spark plug fouling and engine flooding. This will cause
the engine not to start.
AT T ENTION
For gasoline starting in cold ambient temperature < 59°F (15°C): Keep the Multi-Switch in the “START”
position until engine starts. As soon as the engine starts and runs smoothly turn the Multi-Switch to the “RUN”
position. In extreme cold temperatures, this may take several seconds.
AT T ENTION
If the engine starts but does not continue to run make certain that the generator is on a flat, level surface. The
engine is equipped with a low oil sensor that will prevent the engine from running when the oil level falls below a
critical threshold.
Parallel Operation
The parallel connection ports allow you to connect two generators to increase the total available electrical power.
Follow the instructions included with your parallel connection kit for proper installation and operation.
Overload Indicator
Note: The OVERLOAD light may turn on for a few seconds as a large device starts. This is normal for loads
approaching the capacity of this generator.
1. The total combined load through the outlets on the generator must not exceed the running power of the unit.
2. If the OVERLOAD light turns on and the generator stops producing power, it has been overloaded.
3. Turn off and disconnect all electrical devices and stop the engine. Compare device requirements to generator
rating and reduce the total wattage of connected devices if necessary. Move anything that may be limiting
generator ventilation away.
4. Check if any circuit breakers have tripped and make sure that ALL circuit breakers are reset before starting the
generator again.
5. Restart the engine and reconnect devices while being careful to not overload the generator.
Low Oil Indicator
1. If the engine oil level is too low, the LOW OIL light turns on and the engine will automatically shut off.
2. The engine cannot be restarted until the proper amount of oil has been added. Add the appropriate type of oil
until the oil level is at the proper level. SAE 10W-30 oil is recommended for general use.
