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

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
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and build-
ing electrical system damage can occur when nor-
mal operating power returns if unit is used without
an isolation switch.
AE00086
EXTENSION CORD NOTES
Extension cords should be protected by a tough flexi-
ble rubber sheath (IEC 245) or the equivalent to with-
stand 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.

ENGINE SWITCH
The engine switch controls the ignition system.

Ignition circuit is switched on.
The engine can be started.
2 5“STOP”
Ignition circuit is switched off.
The engine will not run.
AE00787
ECONOMY CONTROL SWITCH
1 I “ON”
When the economy control switch is turned “ON”, the
economy control unit controls the engine speed
according to the connected load. The results are better
fuel consumption and less noise.
2 3“OFF”
When the economy control switch is turned “OFF”, the
engine runs at the rated r/min (3,600 r/min) regardless
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 start-
ing current, such as a compressor or a submergible
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 immediately
and consult a Yamaha dealer.

G.F.C.I. RECEPTACLE
The G.F.C.I. (Ground Fault Circuit Interrupter) shuts
off power to the protected receptacles if a ground fault
(electrical leak) is detected.
If the reset button pops out, the equipment plugged
into the receptacle may be faulty. If this happens,
check the equipment carefully. If the equipment
appears to be in good condition, press the reset button
firmly until a click is heard. This will restore power. If
the reset button pops out again, unplug the equipment
immediately. Have the equipment inspected and
repaired by a qualified repairperson before attempting
to use it again.

TO REDUCE THE CHANCE OF ELECTRICAL
SHOCK:
9Do not attempt to operate equipment if the
ground fault circuit interrupter reset button
pops out repeatedly during use.
9Test the ground fault circuit interrupter during
the pre-operation checks according to the
maintenance instructions on page 31.
9Remember that only receptacles labeled
“GFCI”have ground fault circuit interrupter
protection.

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 regu-
lar unleaded gasoline with a pump octane number ((R

may overflow when the fuel warms up and
expands.
9After refueling, make sure the tank cap is tight-
ened securely.

9Immediately wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may deteriorate
painted surfaces or plastic parts.
9Use only unleaded gasoline. The use of leaded

TIP
The choke is not required to start a warm engine.
Push the choke knob in to the original position.
5. Pull slowly on the recoil starter until it is engaged,
then pull it briskly.
6. After the engine starts, warm up the engine until
the engine does not stop when the choke knob is
returned to the original position.
7. Push the choke knob back to the original position.
TIP
When starting the engine in areas where the ambient
temperature is below 0°C (32°F), the engine automati-
cally operates at the rated r/min (3,600 r/min) for three
minutes to warm up the engine regardless of the econ-
omy control switch position. The economy control unit
operates normally afterwards if the economy control
switch is turned to “ON”.

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 inter-
fere 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
starting currents, and cannot therefore be used, even if they lie within the
supply ranges given in the above table. Consult the equipment manufacturer
for further 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.
