and windows are open.
Only use OUTSIDE and
far away from windows,
door, and vents.
2
Read the owner's manual and all labels before operating.
Only operate in well-ventilated areas.
Exhaust gas contains poisonous carbon monoxide.
Check for spilled fuel or fuel leaks.
Stop engine before refueling.
Do not Operate near flammable materials.
Electrocution can occur if generator is used in rain,
snow, or near water, keep this unit dry at all times.
When operating the generator:
Never place a partition or other barrier around the generator.
Do not cover the generator with a box.
Do not place any objects on the generator.

FUEL IS HIGHLY FLAMMABLE AND POISONOUS
9Always turn off the engine when refuelling.
9Never refuel while smoking or in the vicinity of an
open flame.
9Take care not to spill any fuel on the engine or muf-
fler when refuelling.
9Do not leave the generator inside the vehicle or in
the trunk.
9If you swallow any fuel, inhale fuel vapor, or allow
any to get in your eye(s), see your doctor immedi-
ately. If any fuel spills on your skin or clothing,
immediately wash with soap and water and change
your clothes.
9When operating or transporting the generator, be
sure it is kept upright. If it tilts, fuel may leak from
the carburetor or fuel tank.

AE00091
CONNECTION
Before the generator can be connected to a build-
ing’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the build-
ing’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power sup-
ply has failed or has been turned off for line repair.
Backfeeding can electrocute or injure line mainte-
nance personnel. Also, generator and building
electrical system damage can occur when normal
operating power returns if unit is used without an
isolation switch.
WARNING
AE00086
EXTENSION CORD NOTES
Extension cords should be protected by a tough flexible
rubber sheath (IEC 245) or the equivalent to withstand
mechanical stresses.

OIL WARNING LIGHT (Red)
When the oil level falls below the lower level, the oil
warning light (Red) comes on and then the engine
stops automatically. Unless you refill with oil, the engine
will not start again.
TIP
If the engine stalls or does not start, turn the engine
switch to “ON”and then pull the recoil starter. If the oil
warning light flickers for a few seconds, the engine oil is
insufficient. Add oil and restart.
DC PROTECTOR
The DC protector turns to “OFF”2automatically when
electric device being connected to the generator is
operating and current above the rated flows. To use this
equipment again, turn on the DC protector by pressing
its button to “ON”1.
1“ON”
Direct current is output. (This is the default position.)
2“OFF”
Direct current is not output.
Reduce the load of the connected electric device
below the specified rated output of the generator if
the DC protector turns off. If the DC protector turns
off again, stop using the device immediately and
consult a Yamaha dealer.

PRE-OPERATION CHECK
Pre-operation checks should be made each time the
generator is used.
The engine and muffler will be very hot after the
engine has been run.
Avoid touching the engine and muffler while they
are still hot with any part of your body or clothing
during inspection or repair.

FUEL
Make sure there is sufficient fuel in the tank.
Your Yamaha engine has been designed to use regular
unleaded gasoline with a pump octane number ((R +
M)/2) of 86 or higher, or research octane number of 91
or higher.

and expands.
9After refueling, make sure the tank cap is tight-
ened securely.

Make sure the engine oil is at the upper level of the oil
filler hole. Add oil as necessary.
9Immediately wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may deteriorate paint-

9Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts.

APPLICATION RANGE
When using the generator, make sure the total load is within rated output of a generator.
Otherwise, generator damage may occur.
9Do not overload. The total load of all electrical appliances must not exceed the
supply range of the generator. Overloading will damage the generator.
9When supplying precision equipment, electronic controllers, PCs, electronic
computers, microcomputer-based equipment or battery chargers, keep the
generator a sufficient distance away to prevent electrical interference from the
engine. Also ensure that electrical noise from the engine does not interfere
with any other electrical devices located near the generator.
9If the generator is to supply medical equipment, advice should first be obtained
from the manufacturer, a medical professional or hospital.
9Some electrical appliances or general-purpose electric motors have high start-
ing currents, and cannot therefore be used, even if they lie within the supply
ranges given in the above table. Consult the equipment manufacturer for fur-
ther advice.
NOTICE
TIP
9“–” means below.
9Application wattage indicates when each device is
used by itself.
9The simultaneous usage of AC and DC power is
possible but total wattage should not exceed the
rated output.

Overload indicator light (Red)
The overload indicator light (Red) 1comes on when
an overload of a connected electrical device is detect-
ed, the inverter control unit overheats, or the AC output
voltage rises. The electronic breaker will then activate,
stopping power generation in order to protect the gen-
erator and any connected electric devices. The AC pilot
light (Green) will go off and the overload indicator light
(Red) will stay on, but the engine will not stop running.
When the overload indicator light comes on and power
generation stops, proceed as follows:
1. Turn off any connected electric devices and stop
the engine.
2. Reduce the total wattage of connected electric
devices within the application range.
3. Check for blockages in the cooling air inlet and
around the control unit. If any blockages are found,
remove them.
4. After checking, restart the engine.
TIP
9The generator AC output automatically resets
when the engine is stopped and then restarted.
9The overload indicator light (Red) may come on for
a few seconds at first when using electric devices
that require a large starting current, such as a com-
pressor or a submersible pump. However, this is
not a malfunction.
