8. STANDARD TIGHTENING TORQUE
8.1 STANDARD TIGHTENING TORQUE LIST
CAUTION
Tightening at a torque beyond the specified range will cause damage to tightened parts
or loosening, resulting in failure and malfunction of the Machine.
Pay adequate
attention to the tightening operation.
Torque the metric bolts and nuts that have no specific indication, to the values shown in this
table.
Adequate tightening torque is determined with respect to a width across flat (b) of a bolt or nut.
