A swing door operator having a powered driver operable to manipulate a drive unit that rotates a spindle to open a door. As the door is opened, the drive unit compresses a spring engaged with a spring mount that is pivotally connected to the drive unit. The spring mount is pivotable between an operating configuration in which the spring is arranged to be compressed by the drive unit as spindle rotates in the first direction and to expand thereafter to rotate the spindle in a second direction opposite the first direction, and a servicing configuration in which the spring is slidably removable from the spring mount.
