OPERATION
POWER OUTPUT AND DEMAND
The generator should not be run completely unloaded for extended periods otherwise the engine may be damaged. It
is recommended that the generator should always be operated with at least one-third of its rated 120-Volt AC power
output. 120-Volt AC devices have two dierent electric power demands that must be taken into consideration, namely
the running power and the starting/peak power. Both are measured in Watts (typically abbreviated as “W”).
The steady state continuous load is the running power demand and this is often marked on the device near its model number
or serial number. Sometimes the device might only be marked with its voltage (i.e. 120 V) and current draw (e.g. 6 Amp or 6 A),
in which case the running power demand in Watts can be obtained by multiplying the voltage times the current, e.g. 120 V ×
20 A = 2,400 W.
Simple resistive 120-Volt AC devices such as incandescent bulbs, toasters, heaters, etc. have no extra power demand when
starting, and so their starting power demands are the same as their running power demands.
More complex120-Volt AC devices containing inductive or capacitive elements such as electric motors have a momentary
extra power demand when starting, which can be up to seven times the running power demand or more. Manufacturers of
such devices rarely publish this starting power demand and so it’s often necessary to estimate it. A rule of thumb for devices
tted with an electric motor is to apply a starting power multiplier of 1.2 for small hand-held or portable devices and a value
of 3.5 for larger stationary devices. For example, a 900 W angle grinder can be assumed to have a starting power demand
of at least 1.2 × 900 W, which equals 1,080 W. Similarly, a 1,650 W air compressor can be assumed to have a starting power
demand of at least 3.5 × 1,650 W, which equals 5,775 W.
To prevent overloading of the generator’s 120-Volt AC system:
1. Add up the running power demand of all the 120-Volt AC devices that will be connected to the generator at one time. This
total must not be greater than the generator’s specied running power output.
2. Add up the running power demand again, but for the largest motor-driven device use the value of its starting power
demand instead of its running power demand. This total must not be greater than the generator’s specied starting power
output.
3. The total running power demand of all the devices that will be connected to any one of the generator’s outlets must not
exceed the generator’s specied running power output or 3,700 W, whichever is the lesser.
TRANSPORTING THE GENERATOR
The generator should be stopped and both the fuel control switch and fuel cap vent should be turned to the OFF
position before transporting the generator. Keep the unit level during transport to minimize the possibility of fuel leakage
or, if possible, drain out the fuel prior to transport.
If the generator has been operating, allow the unit to cool down before loading it onto the transport vehicle.

BEFORE ADDING/CHECKING ENGINE
FLUIDS AND FUEL, REVIEW SAFETY
SECTION STARTING ON PAGE 5.
DANGER
Filling the fuel tank with gasoline while
the inverter is running can cause
gasoline to leak and come in contact
with hot surfaces that can ignite the
gasoline.
Before starting the inverter, always check the level of:
• Engine oil
• Gasoline in the fuel tank
Once the inverter is started and the engine gets warm, it
is not safe to add gasoline to the fuel tank or engine oil to
the engine while the engine is running or the engine and
muer are hot.
CHECKING AND / OR ADDING ENGINE OIL
WARNING
Internal pressure can build in the
engine crankcase while the engine
is running. Removing the oil ll plug/
dipstick while the engine is hot can
cause extremely hot oil to spray out of
the crankcase and can severely
burn skin. Allow engine oil to cool for
several minutes before removing the
oil ll plug/dipstick.
The unit as shipped does not contain oil in the engine.
You must add engine oil before starting the inverter for
the rst time. See Initial Oil Fill on page 13 for instructions
on checking engine oil level and the procedure for adding
engine oil.
NOTICE
The engine does not contain engine oil as shipped.
Attempting to start the engine without adding engine oil will
permanently damage internal engine components.
The engine is equipped with a low oil shutdown switch. If
the oil level becomes low, the engine may shut down and
not start until the oil is lled to the proper level.
The owner of the inverter is responsible to ensure the
proper oil level is maintained during the operation of the
generator. Failure to maintain the proper oil level can result
in engine damage.
ADDING GASOLINE TO THE FUEL TANK
WARNING
Never refuel the inverter while the
engine is running.
Always turn the engine o and allow
the inverter to cool before refueling.
CAUTION
Avoid prolonged skin contact with
gasoline. Avoid prolonged breathing of
gasoline vapors.
Required Gasoline – Only use gasoline that meets the
following requirements:
• Unleaded gasoline only
• Gasoline with maximum 10% ethanol added
• Gasoline with an 87 octane rating or higher
Filling the Fuel Tank – Follow the steps below to ll the fuel
tank:
1. Shut o the inverter.
2. Allow the inverter to cool down so all surface areas of
the muer and engine are cool to the touch.
3. Move the inverter to a at surface.

7. Check oil level: When checking the engine oil,
remove the oil ll plug/dipstick and wipe it clean.
Thread the oil ll plug/dipstick all the way back in and
then remove and check the oil level on the oil ll plug/
dipstick.
• Acceptable Oil Level – Oil is visible on the
crosshatches between the H and L lines on the oil
ll plug/dipstick (see Figure 14).
• Low Oil – Oil is below the L line on the oil ll plug/
dipstick.
If oil level is below
this line it is too
low to operate.
