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 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 machine, 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 machine in a place where pedestrians or children are not likely to touch the machine.

9 Avoid placing any flammable materials near the exhaust outlet during operation.

1		CONNECTION
			WARNING
		Before the generator can be connected to a build-
		ing’s electrical system, a licensed electrician must
2		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.

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 “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 off 2 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 “ON” 1.

1 “ON”

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

2 “OFF”

Direct current is not output.

Economy control switch

1 I “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 3 “OFF”

When the economy control switch is turned to “OFF” 2, 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” 2 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 1 comes on when the engine starts and produces power.

Overload indicator light (Red)

The overload indicator light 1 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.

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 them.

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 knob

The fuel tank cap 2 is provided with an air vent knob 1 to 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.

Fuel cock knob

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.

Ground (earth) terminal

Ground (earth) terminal 1 connects the earth line for prevention of electric shock.

When the electric device is grounded, be sure to ground the generator also.

Twin Tech

(Terminal for Connecting special cables for parallel running)

This is the terminal for connecting special cables for parallel running of two EF2000iS. The parallel running requires two EF2000iS and the special cables. (The rated output in parallel running is 3.0 kVA and the rated current is 25.0 A.)

The handling, operation procedure and the notes on usage are described in the PARALLEL RUNNING KIT OWNER’S MANUAL included in the Parallel Running Kit. Consult a Yamaha dealer for this Parallel Running Kit.

Fuel

WARNING

9Fuel is highly flammable and poisonous. Check “SAFETY INFORMATION” (See page 2) carefully before filling.

9Do not overfill the fuel tank, otherwise it may overflow when the fuel warms up and expands.

9After fill the fuel, make sure the fuel tank cap is tightened securely.

NOTICE

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 gasoline will cause severe damage to internal engine parts.

Remove the fuel tank cap and fill the fuel into the tank up to the red level 2.

The fuel level in the fuel tank can be checked through the fuel level gauge 1.
