6.2.2 General torque guidelines
Bolts and screws must be properly torqued. This is especially
true if part(s) and/or accessory(ies) are added or replaced. Table
23 provides guidelines on torque levels. The table is intended as
a general guideline and should be applied in conjunction with the
experience and good judgment of the individual performing the
work.
m CAUTION
OVER TORQUING CAN CAUSE PERMANENT DAMAGE WHILE UNDER
TORQUING WILL NOT PROVIDE THE PROPER CLAMPING FORCE AND MAY
EVENTUALLY WORK LOOSE.
