1. SAFETY
DANGER!
USING A GENERATOR INDOORS CAN KILL YOU IN MINUTES.
THE ENGINE EXHAUST FROM THIS PRODUCT CONTAINS CHEMICALS
KNOWN TO CAUSE CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE
HARM.
1.1 OPERATOR SAFETY
WARNING!
Always perform an oil, fuel and air lter check before starting the engine.
Properly clean and maintain the equipment.
Operate the generator according to instructions for safe and
dependable service.
Before operating the generator, read the user guide carefully. Otherwise,
it may result in personal injuries or equipment damage.
Never run the generator in an enclosed area to avoid harm from exhaust
emissions of a poisonous carbon monoxide gas.
Pay attention to the warning labels. The engine exhaust system will
become heated during operation and remain hot immediately after the
engine is stopped.
Gasoline is a highly ammable and explosive liquid. Refuel in a well
ventilated area with the engine stopped.
Use of gasoline with an ethanol content greater than 10% can damage
the engine and fuel system and will void the manufacturer’s warranty.
When refueling the generator, keep it away from cigarettes, open
ames, smoke and/or sparks.
Place the generator at least 3 feet away from buildings or other
equipment during operation.
Run the generator on a level surface. Tilting the generator may result in
fuel spills.
Know how to stop the generator quickly and understand operation of
all the controls. Never permit anyone to operate the generator without
proper instructions.
Keep children, pets and machinery with rotating parts away during
operation.
Do not operate the generator in rain or snow.
Do not allow any moisture to come in contact with the generator.

1.2 AC SAFETY
WARNING!
Before connecting the generator to an electrical device or power cord:
Make sure that everything is in proper working order. Faulty devices or
power cords can lead to an electrical shock.
Turn off the generator immediately if the device begins to operate
abnormally. Then disconnect the device and investigate the problem.
Make sure that the electrical rating of the device does not exceed
that of the generator. If the power level of the device is between the
maximum output power and the running power of the generator, the
generator should not be used for more than 30 minutes.
Connections for standby power to a building’s electrical system must
be done by a qualied electrician and must comply with all applicable
laws and electrical codes. Improper connections may cause serious
injuries to electrical workers during a power outage, and when the
utility power is restored, the generator may explode or cause res. The
generator shall be connected through transfer equipment that switches
all conductors other than the equipment grounding conductor. The
frame of the generator shall be connected to an approved grounding
electrode.
For power outages, permanently installed stationary generators are
better suited for providing backup power to the home. Even a properly
connected portable generator can become overloaded. This may result
in overheating or stressing the generator components, possibly leading
to a generator failure.
1.3 MAINTENANCE SAFETY
WARNING!
After any maintenance is performed, wash immediately using soap and
clean water because repeated exposure to lubricant may cause skin
irritation.
Do not clean the lter element with ammable liquids like gasoline
because an explosion may occur.
Turn off the engine before performing any maintenance. Failure to do so

procedures.
Lubricate all exposed metal parts regularly. See chapter 7.1 for
maintenance schedule.
1.4 OTHER SAFETY TIPS
WARNING!
To avoid breathing in poisonous carbon monoxide from the exhaust
gases, adequate ventilation should be provided if the generator set is
running in a partially enclosed space.
If the generator set is stored outdoors, check all the electrical
components on the control panel before each use. Moisture can
damage the generator and can lead to an electric shock.
Generators vibrate in normal use. During and after the use of the
generator, inspect the generator as well as extension cords and power
supply cords connected to it for damage resulting from vibration. Have
damaged items repaired or replaced as necessary. Do not use plugs or
cords that show signs of damage such as broken or cracked insulation
or damaged blades.
If you start to feel sick, dizzy, or weak after the generator has been
running, move to fresh air RIGHT AWAY. See a doctor. You could have
carbon monoxide poisoning.

2.3 CONTROL FUNCTIONS
EcoMode (Economy Control Switch)
Turn EcoMode ON to minimize fuel consumption. In this mode the
engine will dynamically meet the demand of the electrical load and will
automatically go into an idle state if all loads are disconnected.
Before connecting or removing a high load device to the generator, turn
EcoMode OFF until that device has reached running power.
When EcoMode is OFF, the engine runs at full speed.
Reset Button
If the red overload indicator light is on, press and hold the reset button
for 1 second until the overload indicator light turns off and the green
output indicator light turns on. This will recover generator output without
shutting down the engine.
If the generator is running normally, the RESET button will have no
effect.
NOTE
The RESET button is available a maximum of 5 times for every full start
of the generator. Shut down the generator and restart using the power
switch to refresh available resets.
Output and Overload Indicator
In normal operation, the green output indicator light (READY) will remain
on.
If the generator is overloaded (producing more than 1600W) or a
connected appliance has short-circuited, the output indicator light will
turn off and the overload indicator light will turn on.
USB Ports
A total of 3.1A is available at 5.0V. A single port can draw the full 3.1A or
it will be distributed as needed. For example, a 1A device will only draw
1A.
