4. PRE-OPERATION CHECK
■Be sure to check the generator on a level surface with the engine stopped.
1. Check the engine oil level.
■Using non detergent oil or 2 cycle 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
AMBIENT TEMPERATURE
Loosen the cover screw and remove the left side maintenance cover. Remove the oil filler cap,
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.

NOTE: 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.
You must screw down the dipstick completely to measure the oil level.
2. Check the fuel level.
Use automotive unleaded regular gasoline only. A fuel preservative and stabilizer should be
added to any container of stored fuel.
If the fuel level is low, refill the fuel tank until the level reaches the specified mark.
Never use an oil/gasoline mixture or dirty gasoline.
Avoid getting dirt, dust or water in the fuel tank.
After refueling, tighten the fuel filler cap securely.
■Gasoline is extremely flammable and is explosive under certain conditions.
■Refuel in a well-ventilated area with the engine stopped. Keep all smoking materials, sparks,
and any other source of combustion away from the generator during refueling.
■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 breathing of vapor. KEEP OUT OF REACH
OF CHILDREN.

Gasoline containing alternate fuels
If you decide to use a gasoline containing ethanol, be sure its octane rating is no lower than the
specification. Do not use a blend that contains more than 10% ethanol. Do not use gasoline
containing methanol.
■Fuel system damage or engine performance problems resulting from the use of fuels that
contain an improper alcohol blend are not covered under warranty.
■Before buying fuel from an unfamiliar station, Determine if the fuel contains ethanol and if it
does, confirm the type and percentage of ethanol used. If you notice any undesirable
operating symptoms while using a gasoline that contains ethanol, or one that you think
contains ethanol, replace it by a gasoline that you know has the proper blend.
3. Check the air cleaner
Check the air cleaner element to be sure it is clean and in good condition.
Loosen the cover screw and remove the left side maintenance cover.
Press the latch tab on the top of the air cleaner body, remove the air cleaner cover, check the
element. Clean or replace the element if necessary.

6. GENERATOR USE
Be sure to ground the generator when loads are connected.
■To prevent electrical shock from faulty appliances, the generator should be grounded.
Connect a length of heavy cable between the generator's ground terminal and an external
ground source.
■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. When utility power is restored the generator may explode, burn, or
cause fires in the building's electrical system.
■Do not connect the generator to an automatic transfer device. Severe damage to the inverter
module may result.

■The total wattage of all appliances connected must be considered.
■Do not exceed the current limit specified for any one receptacle.
■Do not connect the generator to a household circuit. This could cause the damage to the
generator or to electrical appliances in the house.
■Do not modify or use the generator for other purpose than it is intended for. Also observe the
following when using the generator.
■Do not connect an extension to exhaust pipe.
■When an extension cable is required, be sure to use a rubber sheathed flexible cable (IEC
245 or equivalent).
■Limit length of extension cables to 195 ft (60 m) for cables of 1.5mm2and 325 feet (100 m) for
cables of 2.5mm2. Long extension cables will reduce usable power due to resistance in the
extension cable.
■Keep the generator away from other electric cables or wires such as commercial power
supply lines.
■The DC receptacle can be used while the AC power is in use. If you use both at the same time,
be sure not to exceed the total power for AC and DC.
■Most appliance motors require more than their rated wattage for start-up.

AC application
1. Start the engine and make sure only the output indicator light (green) comes on.
2. Confirm that the appliance to be used is switched off, and plug in the appliance.
■Substantial overloading that continuously lights the overload indicator light (red) may damage
the generator. Marginal overloading that temporarily lights the overload indicator light (red)
may shorten the service life of the generator.
■Be sure that all appliances are in good working order before connecting them to the generator.
If an appliance begins to operate abnormally, becomes sluggish, or stops suddenly, turn off
the generator engine switch immediately. Disconnect the appliance and examine it for signs
of malfunction.
3. In order to insure the optimum output and the maximum service life of the generator, the
generator should run at a 50% load for the first 20 hours.
Stop the engine if the overload indicator light (red) comes on and investigate the overload source
■Before connecting an appliance to the generator, check that it is in good order and that its
electrical rating does not exceed that of the generator. Connect the power cord of the
appliance and start the engine.
