Yamaha EF2800i, YG2800i Specification

The Yamaha EF2800i and YG2800i generators are compact, portable power solutions designed for reliability and efficiency. Both models feature a maximum AC output of 2,800 watts and a rated output of 2,500 watts, making them suitable for a variety of applications, including recreational, emergency, and small job sites. At the heart of these generators is a 171cc OHV air-cooled, 4-stroke engine, designed to deliver consistent power with improved fuel efficiency and reduced noise levels. The inverter system with Pulse Width Modulation (PWM) ensures clean and stable power output, making it safe for sensitive electronic equipment.

The Yamaha EF2800i and YG2800i come equipped with a large 2.9-gallon fuel tank, providing extended run times of up to 15 hours at a quarter load, ensuring long-lasting power without frequent refueling. The generators feature a centralized control panel for ease of operation, which includes an economy control switch to optimize fuel consumption and reduce noise further when operating under lighter loads. The oil watch warning system is incorporated to prevent engine damage by alerting the user to low oil levels, enhancing the longevity of the unit.

Both models are designed with portability in mind, weighing approximately 68 pounds and featuring a compact frame, making them easy to transport and store. The noise level is rated at 64 to 67 dBA, making these generators relatively quiet for their class. The Yamaha EF2800i and YG2800i are engineered with a focus on durability and user-friendliness, offering reliable power in a versatile and compact design, suitable for various power needs.

Yamaha EF2800i, YG2800i F.A.Q.

How do I properly start the Yamaha EF2800i generator?

To start the Yamaha EF2800i, ensure the generator is on a flat surface. Turn the fuel valve to the "On" position, set the choke to "Start," and turn the engine switch to "On." Pull the recoil starter gently until you feel resistance, then pull sharply to start the engine. Once started, gradually move the choke to the "Run" position.

What should I do if the Yamaha YG2800i won't start?

If the YG2800i won't start, check the fuel level and ensure fresh fuel is used. Verify the spark plug is clean and properly gapped. Inspect the air filter for clogs. Make sure the oil level is adequate and the engine switch is in the "On" position. If issues persist, consult the user manual or a professional technician.

How often should I change the oil in my Yamaha EF2800i generator?

The oil in the Yamaha EF2800i should be changed after the first 20 hours of use, and then every 100 hours of use or at least once a year, whichever comes first. Use SAE 10W-30 oil for optimal performance.

What type of maintenance is required for the Yamaha YG2800i?

Regular maintenance for the YG2800i includes checking and changing the oil, cleaning or replacing the air filter, inspecting the spark plug, and ensuring the fuel system is clean. Conduct these checks every 100 hours of operation or annually.

Can I use the Yamaha EF2800i indoors?

No, the Yamaha EF2800i should never be used indoors. Generators produce carbon monoxide, a deadly gas that can accumulate quickly in enclosed spaces. Always operate the generator outdoors in a well-ventilated area.

What is the recommended load capacity for the Yamaha YG2800i?

The Yamaha YG2800i is designed to handle a continuous running load of 2500 watts and a maximum surge load of 2800 watts. Avoid exceeding this limit to prevent damage to the generator and connected appliances.

How do I store the Yamaha EF2800i when not in use?

When storing the Yamaha EF2800i, drain the fuel tank and carburetor to prevent fuel degradation. Clean the generator thoroughly and store it in a dry, cool place. Cover it to protect from dust and debris. Periodically check the unit if stored for an extended period.

Is it possible to parallel connect two Yamaha EF2800i generators?

No, the Yamaha EF2800i does not support parallel connection. To increase power output, consider using a generator model that offers parallel capability.

What should I do if my Yamaha YG2800i is leaking fuel?

If your YG2800i is leaking fuel, immediately stop using the generator. Check the fuel lines and connections for cracks or loose fittings. Tighten any loose components and replace damaged parts. Contact a professional technician if the issue persists.

How can I reduce noise levels when using the Yamaha EF2800i?

To reduce noise levels, place the EF2800i on a soft surface like grass or a rubber mat to absorb vibrations. Position the exhaust away from occupied areas and consider using a sound-dampening enclosure designed for generators.
