the generator from the box. (two people lifting is
recommended)
The recommended oil type is SAE30 oil automotive oil.
NOTE
Add Engine Oil
DO NOT attempt to crank or start the engine before
it has been properly filled with the recommended
type and amount of oil. Damage to the generator as
a result of failure to follow these instructions will
void your warranty.
CAUTION
Check oil often during the break-in period. Refer to
the Maintenance section for recommended service
intervals.
NOTE
Add Engine Oil Cont’d.
The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.
CAUTION
The generator rotor has a sealed, pre-lubricated ball
bearing that requires no additional lubrication for
the life of the bearing.
NOTE
We consider the first 5 hours of run time to be
the break-in period for the unit. During the break
in period stay at or below 50% of the running
watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the
load will also cause engine speed to vary and help
seat piston rings. After the 5 hour break-in period,
change the oil.
NOTE
Once oil has been added, a visual check should show
oil about 1-2 threads from running out of the fill hole.
If using the dipstick to check oil level, DO NOT screw
in the dipstick while checking.
NOTE
1. Place the generator on a flat, level surface.
2. Remove oil fill cap/dipstick to add oil.

OPERATION
Low Idle Mode
The low idle mode can be activated in order to
minimize fuel consumption and noise while operating the
unit during times of reduced electrical output , allowing
the engine speed to idle during periods of non-use. The
engine speed automatically returns to normal when an
electrical load is connected. When the smart switch is
off, the engine runs at normal operating speed.
Starting the Engine Cont’d.
For periods of high electrical load or momentary
fluctuations, the low idle mode should be
turned OFF.
WARNING
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.
NOTE
Connecting a generator to your electric utility
company’s power lines or to another power source
may be against the law. In addition this action,
if done incorrectly, could damage your generator
and appliances and could cause serious injury or
even death to you or a utility worker who may be
working on nearby power lines. If you plan to run a
portable electric generator during an outage, please
notify your electric utility company immediately
and remember to plug your appliances directly
into the generator. Do not plug the generator into
any electric outlet in your home. Doing so could
create a connection to the utility company power
lines. You are responsible for ensuring that your
generator’s electricity does not feed back into the
electric utility power lines.
If the generator will be connected to a building
electrical system, consult your local utility company
or a qualified electrician. Connections must isolate
generator power from utility power and must comply
with all applicable laws and codes.
NOTE
Connecting Electrical Loads
1. Let the engine stabilize and warm up for a few
minutes after starting
2. Plug in and turn on the desired 230 Volt AC single
phase, 50 Hz electrical loads.
– DO NOT connect 3-phase loads to the generator.
– DO NOT overload the generator.
Keep choke in “Choke” position for only 1 pull
of the recoil starter. After first pull, push choke
in for up to the next 3 pulls of the recoil starter.
Too much choke leads to sparkplug fouling/engine
flooding due to the lack of incoming air. This will
cause the engine not to start.
NOTE
6. Pull the starter cord slowly until resistance is felt
and then pull rapidly.
7. As engine warms up, push the choke lever in to the
“Run” position.

OPERATION
Stopping the Engine
1. Turn off and unplug all electrical loads. Never start
or stop the generator with electrical devices plugged
in or turned on.
2. Let the generator run at no-load for several minutes
to stabilize internal temperatures of the engine and
generator.
3. Turn the fuel valve to the “OFF” position.
4. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.
5. Turn the engine switch to the “OFF” position.
Important:Always ensure that the fuel valve and the
engine switch are in the “OFF” position when the engine
is not in use.
If the engine will not be used for a period of two (2)
weeks or longer, please see the storage section for
proper engine and fuel storage.
NOTE
Do Not Overload Generator
Capacity
Follow these simple steps to calculate the running and
starting watts necessary for your purposes.
1. Select the electrical devices you plan on running at
the same time.
2. Total the running watts of these items. This is
the amount of power you need to keep your items
running.
3. Identify the highest starting wattage of all devices
identified in step 1. Add this number to the number
calculated in step 2. Surge wattage is the extra
burst of power needed to start some electric driven
equipment. Following the steps listed under “Power
Management” will guarantee that only one device
will be starting at a time.
Power Management
Use the following formula to convert voltage and
amperage to watts:
Volts x Amps = Watts
To prolong the life of your generator and attached
devices, follow these steps to add electrical load:
1. Start the generator with no electrical load attached.
2. Allow the engine to run for several minutes to
stabilize.
3. Plug in and turn on the first item. It is best to
attach the item with the largest load first.
4. Allow the engine to stabilize.
5. Plug in and turn on the next item.
6. Allow the engine to stabilize.
7. Repeat steps 5-6 for each additional item.
Never exceed the specified capacity when adding
loads to the generator.

OPERATION
Operation at High Altitude
The density of air at high altitude is lower than at sea
level. Engine power is reduced as the air mass and air-
fuel ratio decrease. Engine power and generator output
will be reduced approximately 3½% for every 1000
feet of elevation above sea level. This is a natural trend
and cannot be changed by adjusting the engine. At high
altitudes increased exhaust emissions can also result
due to the increased enrichment of the air fuel ratio.
Other high altitude issues can include hard starting,
increased fuel consumption and spark plug fouling.
Overload Operation
The overload indicator light will turn on when the rated
load is exceeded. When the maximum load is reached,
the LED will blink and cut power to the receptacles.
To recover the power, shut down the generator, wait until
the light turns off and restart the generator.

MAINTENANCE AND STORAGE
Generator Maintenance
Make certain that the generator is kept clean and stored
properly. Only operate the unit on a flat, level surface in
a clean, dry operating environment. DO NOT expose the
unit to extreme conditions, excessive dust, dirt, moisture
or corrosive vapors.
Use a damp cloth to clean exterior surfaces of the generator.
Use a soft bristle brush to remove dirt and oil.
Use an air compressor (25 PSI) to clear dirt and debris
from the generator.
Inspect all air vents and cooling slots to ensure that they
are clean and unobstructed.
DO NOT spray engine with water.
Water can enter the generator through the cooling
slots and damage the generator windings. It can
also contaminate the fuel system.
CAUTION
Gasoline, gasoline vapors and liquid petroleum gas
(LPG/propane) are highly flammable and extremely
explosive.
Fire or explosion can cause severe burns or death.
Only fill or drain fuel outdoors in a well-ventilated
area. Do not pump gasoline directly into the
generator. Use an approved container to transfer the
fuel to the generator. Never use a fuel container,
hose, cylinder or any other fuel related item that
is damaged or appears damaged. Do not overfill
the fuel tank. Always keep fuel away from sparks,
open flames, pilot lights, heat and other sources of
ignition. Do not light or smoke cigarettes.
DANGER
Short Term Storage Cont’d.
Short Term Storage (up to 1 year)
Petrol in the fuel tank has a maximum shelf life of up
to 1 year with the addition of properly formulated fuel
stabilizers and if stored in a cool, dry place. Petrol
in the carburetor, however, WILL gum up and clog the
carburetor if it isn’t used or drained within 2 weeks.
Long Term Storage (over 1 year)
For storage over 1 year, the fuel tank and carburetor must
be completely drained of gasoline.
1. Be sure all appliances are disconnected from the
generator.
2. Add aproperly formulated fuel stabilizer to the fuel
tank.
3. Run the generator for 10 minutes so the treated fuel
cycles through the fuel system and carburetor.
4. Run Dry Option:
a. Let the generator run to fuel complete starvation.
b. Turn engine switch to the “OFF” position.
c. Allow generator to cool completely.
5. Drain Fuel Option:
a. Turn engine switch to the “OFF” position.
b. Allow generator to cool completely.
