WARNING
Loose or overtorqued bolts can cause death,
severe injury, or property damage. Maintain
proper bolt torque. Visually check bolts daily.
Check torque every 50 hours.
WARNING
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 clamping force cannot be
achieved using the old bolts and nuts.
