I have got a Genie S-105 lift, I am experiencing Boom Speed Calibration errors. Error text are as follows: 1. Primary Boom UP/DN Speed not Calibrated. 2. Primary Boom EXT/RET Speed not Calibrated. 3. TT Rotation Speed not Calibrated. Manual says that automatic speed calibration is required so I tried to calibrate as given in maintenance manual but not succeeded. Can any brother help me regarding this fault. Thanks in advance.
