Disclosed power machines include a lift arm structure having a first arm pivotally mounted to a frame and a second arm, coupled to an implement interface, configured to telescopically extend from and retract into the first arm. A control system controls a first actuator to raise and lower the first arm, and controls a second actuator to extend and retract the second arm relative to the first arm. The control system is configured to control the first and second actuators to implement a lift operation, responsive to an operator input. During the lift operation, the first actuator raises the first arm and the second actuator extends and retracts the second arm to maintain a substantially linear path, such as a vertical path, of the implement interface or an implement attached to the implement interface.
