Loose or overtorqued bolts can cause death, severe
injury, or property damage. Maintain proper bolt torque.
Visually check bolts daily. Check torque every 100
hours.
In critical applications (such as Turntable Bearing Bolts
and any grade 8 or grade 9 bolts), once the old bolts
and nuts have been loosened, they must be replaced
rather than re-tightened and re-torqued. Original clamp-
ing force cannot be achieved using the old bolts and
nuts.
