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 (back feeding)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.
AE00086
EXTENSION CORD NOTES
Extension cords should be protected by a tough flexible
rubber sheath (I E C 245) or the equivalent to withstand
mechanical stress.

CONTROL FUNCTION
Engine switch
The engine switch controls the ignition system.
①“ON”
Lgnition circuit is switched on.
The engine can be started.
②“stop”
Lgnition circuit is switched off.
The engine will not run,
OIL Warning light (Red)
When the oil level falls below the lower, 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 “ON” and the 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 off automatically when elec②-
tric device being connected to the generator is operat-
ing and current above the rated flows. To use
this equipment again turn on the DC protector
bypressingitsbuttonto“ON” .①
”ON”①

11

Reduce the load of the connected electric device
below the specified rated output of the generator
if the DC protractor turns off again, stop using the
device immediately and consult a Yamaha dealer.
Economy control switch
①1 “ON”
When the economy control switch is turned to
“on” ①,The economy control unit controls the
engine speed According to the connected load.
the results are better Fuel consumption and less
noise.
②“OFF”
When the economy control switch is turned to
” OFF” ②,The engine runs at the rated r/min
(4,500 r/min) regard-Less of whether is
a load connected or not.
TIP
The economy control switch must be turned to
“ OFF” ②
when using electric devices that require a large
starting current, such as a compressor of a
submergible pump.
AC pilot light (Green)
The AC pilot light ①comes on when the engines
starts and produces power.
12

Overload indicator light (Red)
The overload indicator light comes on when an①
over- of a connected electrical decide is detected,
the inverter control unit overheats, or the AC output
Voltage rises. Then, theAC protector will trip, stopping
power generation in order to protect the generator 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 rated output
3、Check for blockages in the cooling air inlet and
around the control unit, if any blockages are found
remove
4、After checking ,restart the genine.
TIP
The overload indicator light may come on for a few sec-
onds at first when using electric deices that require a
large starting current, such as a compressor or a sub-
mergible pump.However, this is not a malfunction.
Fuel tank cap
Remove the fuel tank cap by turning it counter clock-
wise.
13

Fuel tank cap air vent knob
Thefueltankcap is②provided with an air vent
Knob ①to stop fuel flow.
The air vent knob must be turned to “ON”. This
will allow fuel to flow to the carburetor and the
engine to run, when the engine is not in use, turn
the air vent knob to “OFF” to stop fuel flow.
Fuelcockknob
The fuel cock supplies fuel from the fuel tank to
the car- buretor.
①“ON”
With the knob in this position, fuel flows to the
carburet- 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.

PREPARATION
Fuel
·fuel is highly flammable and poisonous. Check
“SAFETYINFORMATION”(See page 1)careful-
Lybeforefilling.
·Do not overfill the fuel tank, otherwise it may
overflowwhen the fuel warms up and expands.
·After fill the fuel. make sure the fuel tank cap is
tightened securely.
·Immediately wipe off spilled fuel with a clean,
dry,softcloth, since fuel may deteriorate paint-
ed surfaces or plastic parts.
·Use only unleaded gasoline. The use of laded
gasoline will cause severe damage to internal
engineparts.
Remove the fuel tank cap and fill the fuel into the tank
uptothelevel ②.

PRE-OPERATION CHECK
If any item in the pre-operation check is not
work-ing properly, have it inspected and repaired
before operating the generator.
The condition of a generator is the owner’ responsibil-
Ity. Vital components can start to deteriorate quickly
and unexpectedly, even if the generator unused.
TIP
Pre-operation checks should be made each time the
generator is used.
Pre –operation check
Fuel (see page 11)
·Check fuel level in fuel tank.
·Refuel if necessary.
Fuelline
·Check fuel hose for crack or damage.
·Replace if necessary.
Engine oil (See page 12)
·Check oil level in engine.
·If necessary, add recommended oil to specified level.
·Check generator for oil leakage.
The point where abnormality was recognized by
Use
·Check operation.
·If necessary, consult a Yamaha dealer.
17

OPERATION
·Never operate the engine in a closed area or it
may cause unconsciousness and death within
a short tine. Operate the engine in a well venti-
latedarea.
·before starting the engine, do not connect any
electric devices.
Starting the engine

5、Pull the choke knob ①fully out.
①choke knob
TIP
The choke is not required to start a warm engine.
Push the choke knob in to the original position,
6、Pull slowly on the recoil starter until it is
engaged, then pull it briskly.
TIP
Grasp the carrying handle firmly to prevent the
genera-tor from falling over when pulling the
recoil starter.
7、After the engine starts, warm up the engine
until the engine does not stop when the choke
knob is returned the original position.
TIP
When starting the engine, with the economy,
control switch “ON” , and there is no load on the
generator:
·in ambient temperature below 0℃(32℉)，the
engine will run at the rated r/min (4,500 r/min) for
5 minutes to warm up the engine,
·in ambient temperature below 5℃(41℉),the
engine will run at the 4,500 r/min for 3 minutes to
warm up the engine.
The economy control unit operates normally after
the above time period, while the economy control
switchis“ON”.
