Exhaust fumes are poisonous

9 Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

9NEVER use inside a home or garage, EVEN IF doors and windows are open.

9Only use OUTSIDE and far away from windows, doors, and vents.

AE00075

Fuel is highly flammable and poisonous

9 Always 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 muffler when refueling.

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 immediately. 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.

AE00843

Engine and muffler may be hot

9Place the generator in a place where pedestrians or children are not likely to touch the machine.

Electric shock prevention

9 Never operate the engine in rain or snow.

9Never touch the generator with wet hands or electrical shock will occur.

9Connect the Ground (earth) terminal to a ground source. In order to prevent electrical shock, the generator must be grounded when using an electrical device with a ground plug.

1	Connection
		WARNING
	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-
2	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

2supply has failed or has been turned off for line repair. Backfeeding can electrocute or injure line maintenance personnel. Also, generator and building electrical system damage can occur when normal operating power returns if unit is used without an isolation switch.

Extension cord notes

Extension cords should be protected by a tough flexible rubber sheath (IEC 245) or the equivalent to withstand mechanical stresses.

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. Electrocution or property damage can occur: Do not connect this generator to any building’s electrical system unless an isolation switch has been installed by a licensed electrician. Refer to the owner’s manual. 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.

1

7DK-018

Ignition circuit is switched on. The engine can be started.

2 “5” (STOP)

Ignition circuit is switched off. The engine will not run.

Recoil starter

The recoil starter is used to start the engine.

Pull the recoil starter slowly until it is engaged, then pull it briskly.

NOTICE

9 Pull the recoil starter handle straight.

9 Return the recoil starter handle slowly.

9 Do not touch the recoil starter handle while the generator is operating.

AE00111

Oil warning light (Red)

When the oil level falls below the lower level, the oil warning light 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 “7” (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 “3” (OFF) automatically 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 “I” (ON).

1 “I” (ON)

Direct current is output. (This is the default position.)

2 “3” (OFF)

Direct current is not output.

NOTICE

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.

AE00142

Economy control switch

1 “I” (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.

2 “3” (OFF)

When the economy control switch is turned to OFF, the engine runs at the rated r/min (4,500 r/min) regardless of whether 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 of a submersible pump.

AC pilot light (Green)

The AC pilot light comes on when the engine starts and produces power.

1 AC pilot light

AE01087

Overload indicator light (Red)

The overload indicator light comes on when an overload of a connected electrical device is detected, the inverter control unit overheats, or the AC output voltage rises. Then, the AC 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.

1 Overload indicator light

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 engine.

TIP

The overload indicator light may come on for a few seconds at first when using electric devices that require a large starting current, such as a compressor or a submersible pump. However, this is not a malfunction.

Fuel tank cap

Remove the fuel tank cap by turning it counterclockwise.

Fuel tank cap air vent lever

The fuel tank cap is provided with an air vent lever to stop fuel flow.

The air vent lever 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 lever to OFF to stop fuel flow.

Fuel petcock

The fuel cock supplies fuel from the fuel tank to the carburetor.

The fuel cock has two positions.

1 ON

With the knob in this position, fuel flows to the carburetor. 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.

Twin Tech (Parallel generator operation)

Two EF2000iSv2 generators can be operated in paral-

lel to increase the rated output to 3.0 kVA and the

rated current to 25.0 A. For parallel operation, use

only a special parallel cable set (optional equipment)

approved by Yamaha; contact your Yamaha dealer for

7DK-042a the proper parallel cable set.

The handling, operation procedure and the notes on usage are described in the parallel cable set owner’s manual included in the parallel cable set. Consult a Yamaha dealer for this parallel cable set.

TIP

The EF2000iSv2 may be connected in parallel with an earlier model Yamaha EF2000iS. However, a second Yamaha EF2000iSv2 is recommended to use the full capabilities of this model.

NOTICE

To avoid severe damage to the generators or other equipment:

9 Never attempt to parallel Yamaha generators of different outputs or a Yamaha generator with any other brand.

9Connect the parallel cable set to the generators before starting the generators and turn off the generators before disconnecting them. Never connect the parallel cable set to running

generators or disconnect them from the generators during parallel operation.

9 Do not use parallel cable set with only one generator or with just one generator running.

9During parallel operation, do not use the AC receptacles on the generator control panel.

9 Never allow the parallel cable set to hang close to the exhaust side of the generator. Heat from the exhaust could damage the parallel cables.

9Do not attempt to modify the parallel cable set in any way, such as to try to use three generators.
