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.

CONNECTION NOTES
9Avoid connecting the generator to commercial
power outlet.
9Avoid connecting the generator in parallel with any
other generator.
1Correct
2Incorrect
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
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 comes on and then the engine stops auto-
matically. 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 “START” or pull the recoil starter. If the oil
warning light comes on, the engine oil is insufficient.
Add oil and restart.

ECONOMY CONTROL SWITCH
1I “ON”
When the economy control switch is turned to “ON”,
the economy control unit controls the engine speed
according to the connected load. The results are better
fuel consumption and less noise.
23“OFF”
When the economy control switch is turned to “OFF”,
the engine runs at the rated r/min (3,800 r/min) regard-
less of whether there is a load connected or not.
TIP
The economy control switch must be turned to “OFF”
when using electric devices that require a large starting
current, such as a compressor or a submersible pump.

DC PROTECTOR
The DC protector turns off automatically when electric
device being connected to the generator is operating
and current above the rated flows. To use this equip-
ment again, turn on the DC protector by pressing its
button to “RESET”.
1“RESET”
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 immedi-
ately and consult a Yamaha dealer.

FUEL COCK KNOB
The fuel cock supplies fuel from the fuel tank to the car-
buretor. The fuel cock has two positions.
1“ON”
With the knob in this position, fuel flows to the carbure-
tor.
Normal using is done with the knob in this position.
2“OFF”
With the knob in this position, fuel will not flow. Always
turn the knob to this position when the engine is not
running.

PRE-OPERATION CHECK
Pre-operation checks should be made each time the
generator is used.
The engine and the muffler will be very hot after the
engine has been run.
Avoid touching the engine and the muffler while
they are still hot with any part of your body or cloth-
ing 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.
1Fuel level gauge
4Fuel filter
9Fuel is highly flammable and poisonous. Check
“SAFETY INFORMATION” (See page 4) careful-
ly before refueling.
9Do not fill above the top of the fuel filter or it
may overflow when the fuel warms up and
expands.
9After refueling, make sure the fuel tank cap is
tightened securely.
