 Use 
 S1 and continue to work continuous S3, feathers environmental temperature +50 ℃. 
 Table refers to the rated current of running the line at the end of the rated current, but if the power supply non-rated fixed value, is bound to cause a corresponding change in the rated current. Ambient temperature: -20 ℃ ~ +50 ℃, hydraulic oil: DB-25 (SY1351-77) is lower than -20 ℃, with the YH-10 hydraulic oil, from time to install the heater with a DB-25 Pump, must be installed heaters. Travel time is 20 ℃ ambient temperature when measured.
