Torque Specifications
The following chart depicts the torque specifications for all screws and nuts used in the machine. They
should be followed unless indicated otherwise in this manual (i.e., screws going into plastic materials
require lower torque).
•
Note: Reduce torque specifications when attaching optical sensors by 10% to prevent damage
to the sensor housing. Use minimum torque when screwing into or clamping plastic surfaces.
