Yamaha EF2000iSv2 Specification

The Yamaha EF2000iSv2 is a versatile and compact inverter generator designed for efficient power delivery and portability. It features a 79cc, air-cooled, OHV 4-stroke engine, which provides reliable performance with a maximum AC output of 2000 watts and a rated AC output of 1600 watts. The generator's inverter system produces clean power with a sine wave as pure as or purer than commercial power, making it safe for sensitive electronics like laptops, smartphones, and other sensitive devices.

Weighing approximately 44.1 pounds, the EF2000iSv2 is highly portable, aided by an ergonomic handle that ensures easy transportation. The unit's dimensions are 19.3 x 11.0 x 17.9 inches, making it compact enough for storage and transportation. Equipped with Yamaha’s Smart Throttle technology, the generator automatically adjusts engine speed based on load, enhancing fuel efficiency, reducing noise, and extending engine life. It can run up to 10.5 hours at a quarter load on a single tank of fuel, which has a capacity of 1.1 gallons.

The generator operates quietly with a noise level of 51.5 to 61 dBA, making it suitable for camping, tailgating, and other outdoor activities where noise reduction is important. It also features parallel capability, allowing users to connect two EF2000iSv2 units for increased power output. The unit includes an oil-watch warning system to prevent engine damage from low oil levels and a fuel gauge for convenient fuel management. Overall, the Yamaha EF2000iSv2 offers a blend of efficiency, reliability, and portability, making it a popular choice among portable inverter generators.

Yamaha EF2000iSv2 F.A.Q.

How do I properly start the Yamaha EF2000iSv2 generator?

To start the Yamaha EF2000iSv2, first ensure the generator is on a flat surface. Turn the fuel petcock to "On," then switch the engine switch to "On." Move the choke lever to "Start" if the engine is cold. Pull the recoil starter gently until resistance is felt, then pull quickly to start the engine. Once started, slowly move the choke to "Run."

What maintenance steps should I follow for the Yamaha EF2000iSv2?

Regular maintenance for the Yamaha EF2000iSv2 includes checking and cleaning the air filter, changing engine oil every 6 months or 100 hours, and inspecting the spark plug for wear. Additionally, inspect the muffler and spark arrestor periodically for blockages.

How can I troubleshoot if the generator doesn't start?

If the generator doesn't start, check the fuel level and ensure the fuel valve is open. Verify that the engine switch is in the "On" position. Check the oil level, as the generator won't start if it's too low. Inspect the spark plug and replace it if fouled. Ensure the choke is set correctly based on the engine's temperature.

What type of oil is recommended for the Yamaha EF2000iSv2?

Yamaha recommends using SAE 10W-40 oil for the EF2000iSv2 generator. Use a high-quality 4-stroke engine oil that is API service class SE or higher.

How do I perform an oil change on the Yamaha EF2000iSv2?

To change the oil, turn off the engine and let it cool. Remove the oil filler cap and place a container under the oil drain plug. Remove the drain plug and allow the oil to drain completely. Reinstall the drain plug and fill with new oil up to the specified level. Replace the oil filler cap securely.

What is the procedure for cleaning the air filter?

Remove the air filter cover and take out the filter element. Wash the foam element in warm, soapy water and rinse thoroughly. Allow it to dry completely. Lightly oil the foam element with engine oil and squeeze out any excess. Reinstall the filter and cover securely.

How do I store the generator when not in use for extended periods?

For extended storage, drain the fuel tank and run the engine until it stops to empty the carburetor. Change the oil and remove the spark plug, adding a small amount of oil to the cylinder before reinserting the plug. Store in a dry, well-ventilated area, away from direct sunlight.

What should I do if the generator is overloaded?

If the generator is overloaded, it will automatically shut off. Reduce the electrical load by unplugging some devices. Reset the overload indicator by pressing the reset button on the control panel. Restart the generator and ensure the load does not exceed the rated capacity.

Can the Yamaha EF2000iSv2 be used with sensitive electronics?

Yes, the Yamaha EF2000iSv2 is equipped with an inverter system that provides clean and stable power suitable for sensitive electronics such as laptops, smartphones, and audio equipment.

How do I check the oil level in the generator?

To check the oil level, ensure the generator is on a level surface and the engine is off. Remove the oil filler cap and wipe the dipstick clean. Insert the dipstick without screwing it in, then remove it to check the oil level. Add oil if the level is below the recommended mark.
