instrument before opening the autosampler cover. Do not connect the
power cable to the autosampler while the covers are removed.

belts, and the gripper assembly is done by Agilent-trained service personnel.
There are no other field-replaceable parts in the transport assembly. If any
other component is defective (flex board, spindles, plastic parts) the
complete unit must be exchanged.
