The references in the manual to certain sections of the machine are oriented as if you were facing the front of the AMAYA as shown below. Example: The "left" transparent arm cover is on the left side of the machine when you face it from the front, but is on the right side if you face it from the rear. The part however, is called the "left" transparent arm cover since it is installed on the left side, oriented as you face the machine from the front.
The left and right sides of the machine are oriented just as if you were facing it from the front side of the machine directly.
The rear of the machine refers to the entire back side of the AMAYA.
The front part of the machine refers to the entire front section of the machine.
The upper arm assembly, lower arm assembly, needlecase, user interface, and thread tree refer to the entire individual assembly and associated components.
