Why is the warranty of diesel generator set one year only or one-thousand working hours? Here are the reasons:

REASON 1: Any quality problem of mechanical-electrical equipments will occur within six months or five-hundred working hours. This is the basis of one-year warranty. Any failure that occurs after that period could possibly be the result of inappropriate operation rather than quality problem.

REASON 2: Most problems of mechanical-electrical equipment will occur at the beginning period of using. After the beginning cooperative period, the equipment should be working stably with few failure.

REASON 3: According to Chinese economic regulations, any quality objections should be placed within six months right after installation and adjustment. The warranty of one-year or one-thousand, whichever reaches first, is in line with the Chinese economic regulations.

So one year warranty is enough, and it's the same as many world-famous brand. We can offer a two-year warranty only with a differnt price, and great after sale service and technical support whe the warranty expires.
