 TORQUE SPECIFICATION
The following torque specifications must be
adhered to on every machine. When applying
torque to multi-secured fastener components,
the several studs should be tightened in
gradual stages and in a pattern that will avoid
warpage
 to the item being secured. Torque
settings are for dry, clean threads. Torquing
should always be done to the nut, never the
bolt head.
NOTE:
Certain items with other than standard thread
pitches
 may require differing torque.
