Torque Specications
The following chart depicts the torque specications 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 specications when attaching optical sensors by 10% to prevent damage
to the sensor housing. Use minimum torque when screwing into or clamping plastic surfaces.
