Note：CT250/300/250A/300Aparameters are suitable for ambient
temperature 25℃. In a low-temperature environment, the load and
endurance will be reduced. If the low-speed mode is started, the
endurance will be reduced accordingly. This product is recommended
to be used within 1000 meters above sea level. It is recommended to
use under ambient humidity range of 45%-85% (no frost or snow).
WARNING ：The center of gravity for the cargo should be
located in the center of the loading board. If the center of gravity
of the cargo exceeds the loading board, it should not be
transported by using the CT250/300/250A/300A.
