CAUTION
Risk of equipment damage or personal injury. The
Zaxis module is heavy and will fall if not held.
Nordson EFD recommends that the Zaxis module be
held by an assistant during disassembly.
Tightly grasp the Zaxis module and then
remove the four (4) screws on the left and right
sides of the Zaxis module that fasten it to the
Xaxis linear guideway.
NOTE: Nordson EFD recommends that
the Zaxis module be held by an assistant;
alternatively, you can carefully place the Zaxis
module on the top the robot in a position that
will not strain any connections.

timing belt from the idler pulley. This loosens
the timing belt enough to remove it from the
idler and timing pulleys.
NOTE: The screw only needs to be loosened,
not completely removed.
