Description

Technical Field

[0002] At present, most generators in low-temperature areas are difficult to start without auxiliary heating measures, and the low temperature is more obvious in winter.

[0003] Existing solutions generally add a manual button on the panel to manually heat and restart. There are hidden dangers in the operation.
