| description | Power machines having hydraulic systems and controllers configured to prohibit, limit, or allow full operation of the hydraulic systems based upon measured temperature of the hydraulic oil in the system are provided. Also included are methods of controlling the hydraulic systems. In the methods implemented by the controllers, determinations are made as to whether the temperature of the hydraulic oil is below a first (and lowest) set point temperature, above a second (and higher) set point temperature, or between the first and second set point temperatures. The controllers then either prohibit hydraulic system operation, allow limited hydraulic system operation, or allow full hydraulic system operation, based upon the measured temperature in comparison to the two or more set point temperatures. |
