Troubleshooting at start-up

Description of frequently occurring problems, particularly those occurring right after purchase, and techniques for managing them

Simple troubleshooting at start-up

Typical troubleshooting procedures required immediately after purchase. Also, refer to the pages of “Frequently Asked Questions” for others.

Engine does not start! First, check the following:

Check 1: Is the engine switch turned to ON?

If the engine switch is in the "STOP " position, it cannot be started.

There are also models that are equipped with an AC switch, which is not related to the start of the engine.

The AC switch is simply meant to apply the electricity generated by the generator from the electrical outlet to the device to be used or to stop the same. It is not a switch for starting the generator.

Check 2: Has the specified amount of engine oil been introduced?

The Yamaha four-stroke generator is equipped with an oil-warning device to protect the engines of all models from damage. When the engine oil level is reduced below a specified level, the oil-warning device stops the engine automatically and restart becomes impossible. Restart can only be performed if the engine oil is replenished up to the specified level.

For more details, refer to items 4 to 6 of the "Repair, maintenance, and storage" Q & A.

Since the required amount of engine oil and the oil level actuating the oil-warning device depend upon the model, refer to the instruction manual.

Check 3: is the fuel cock turned to ON (open)?

Gasoline is obviously contained, but if the fuel cock is in the OFF (closed) position, this gasoline will not flow.
