Yamaha Generator Theory & Diagnostics Guide
Ventilation
Be aware of the surroundings where generators are being used. Three (3) feet of clear space is necessary for
safe operation. Adequate ventilation is also necessary, as the generator’s engine needs fresh air for the intake,
and the exhaust must be safely vented. Refer to the Owner’s Manual for complete information.
Lubrication System
The engine units of all Yamaha conventional and inverter generators use a splash type oiling system.
Cooling System
The centrifugal fan equipped on the rotor performs forced air cooling of the system over the path listed below.
Each part of the system is therefore continuously kept at a stable operating temperature with only a single
fan.
Cooling systems will vary from one model to another. The EF3000iSE is shown here as an example. Refer to
the Owner’s or Service Manual for model specific information.
• Cooling air path
• Control unit cover
• Control unit
• Alternator
• Engine (cylinder)
• Muffler
Generator Storage
To prepare a Yamaha generator for storage follow these basic
procedures:
•
The carburetor float bowl should be emptied using the
float bowl drain screw located on the float bowl.
•
The fuel tank should be full and contain the proper amount
of a fuel stabilizer.
•
The unit should be covered and stored in a cool dry
place.
•
Refer to the Owner’s or Service Manual for complete stor-
age information.
