Torque Specifications

bar.bmp

The following chart depicts the torque specifications for all screws and nuts used in the AMAYA embroidery machine.  They should be followed unless indicated otherwise in this manual (i.e., screws going into plastic materials require lighter 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.
