Common fault analysis
• The environmental requirements of the generator:
• Suitable temperature: -15º C -40º C.
• Suitable humidity: lower than 95%
• Suitable altitude: under 1,000 meters (it should be used with lower power in districts higher than 1,000 meters).
• The
generator set can only be loaded to the rated power under the specified environment conditions. If the environment
conditions are inconsistent with the above standards, or if the cooling conditions of the engine and generator set are
defective; for example, when running in limited areas, it is necessary to reduce the power. It is also necessary to reduce
the power when the temperature, altitude and relative humidity exceed the standards.
• If there is no problem with the conditions above, please turn to the nearby dealer or after-sales service center
for consultants.
