WARNING
Operate carefully to ensure safety.
1. SAFETY INSTRUCTIONS
WARNING
Our generators are designed to give safe and
depend-able service if operated according to
instructions.
Read and understand the Owner's Manual before
operating the generator. Failure to do so could result
in personal injury or equipment damage.
WARNING
WARNING
Exhaust gas contains poisonous carbon monoxide.
Never run the generator in an enclosed area.
Be sure to provide adequate ventilation.
The muffler becomes very hot during operation and
remains hot for a while after stopping the engine.
Be careful not to touch the muffler while it is hot.
The engine exhaust system will be heated during
operation and remain hot immediately after stopping
the engine.
To prevent scalding, pay attention to the warning
marks attached to the generator.
Gasoline is extremely flammable and explosive under certain conditions.
Refuel in a well ventilated area with the engine stopped.
Keep away from cigarette, smoke and sparks when re-fueling the
generator. Always refuel in a well-ventilated location.
Wipe up spilled gasoline at once.
Usage of generator should be limited in ambient where the risk of fire may
be high.

WARNING
WARNING
Connections for standby power to a building's electrical system must be
made by a qualified electrician and must comply with all applicable laws and
electrical codes. Improper connections can allow electrical current from the
generator to back feed into the utility lines. Such back feed may electrocute
utility company workers or others who contact the lines during a power
outage, and when utility power is restored, the generator may explode, burn,
or cause fires in the building's electrical system.
Always make a pre-operation inspection before you start the engine. You
may prevent an accident or equipment damage.
Place the generator at least 1m(3ft) away from buildings or other
equipment during operation.
Operate the generator on a level surface.
If the generator is tiled, fuel spillage may result.
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 and pets away from the generator when it is in operation.
Keep away from rotating parts while the generator is running.
The generator is a potential source of electrical shocks when misused; do
not operate with wet hands.
Do not operate the generator in rain or snow and do not let it get wet.

SMART throttle:
Engine speed is kept at idle automatically when the electrical appliance is
disconnected and it returns to the proper speed to power of the electrical load
when electrical appliance is connected. This position is recommended to
minimize the fuel consumption while in operation.
OFF:
Note: Smart throttle system does not operate. Engine speed is kept at thigh-
speed lever.
Smart throttle system does not operate effectively if the electrical
appliance requires the big electric power.
When high electrical loads are connected simultaneously turn the smart
throttle switch to the OFF position to re-duce voltage changes.

4. PRE-OPERATION CHECK
Be sure to check the generator on a level surface with the engine stopped.
1. Check the engine oil level.
CAUTION
-25 -30
-15 -40
10W-30
15W-40
Ambient temperature Engine oil type
Using nondetergent oil or 2-stroke engine oil could shorten the engine's
service life.
Use a high-detergent, premium quality 4-stroke engine oil, certified to
meet or exceed U.S. automobile manufacturer's requirements for API
Service Classification SG/SF.
Select the appropriate viscosity for the average temperature in your area.
SAE Viscosity Grades
CAUTION
CAUTION
Store and use the oil carefully in order to prevent dust or dirty flowing into
the oil. If oil is overfilled, wipe it up at once.
Never mix different kinds of oil.
Remove and wipe the dipstick with a clean rag. Check the oil level by inserting
the dipstick in the filler hole without screwing it in.
If the oil level is below the end of the dipstick, refill the recommended oil up to the
top of the oil filler neck.
Running the engine with insufficient oil can cause serious engine damage.
The Low Oil Alarm System will automatically stop the engine before the oil
level falls below the safe limit. However, to avoid the inconvenience of an
unexpected shutdown, it is still advisable to visually inspect the oil level
regularly.

2. Check the fuel level.
Use automotive gasoline (Unleaded or low-leaded is preferred to minimize
combustion chamber deposits).
If the fuel level is low, refuel the fuel tank until the level as specified.
Never use an oil/gasoline mixture or dirty gasoline.
Avoid getting dirt, dust or water in the fuel tank.
After refueling, tighten the oil rule seurely.
WARNING
Gasoline is extremely flammable and is explosive under certain conditions.
Refuel in a well-ventilated area with the engine stopped.
Do not smoke or alow flames or sparks in the area where the engine is
refueled or where gasoline is stored.
Do not overfill the fuel tank (there should be no fuel above the upper limit
mark). After refueling, make sure the tank cap is closed properly and
securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
ignite, if any fuel is spilled, make sure the area is dry before starting the
engine.
Avoid repeated or prolonged contact with skin or breath-ing of vapor,
KEEP OUT OF REACH OF CHILDREN.
