INSPECT / TORQUE BOLTS
Inspect all bolts for damage. Check the torque of all bolts and replace any bolt that is damaged or has be re-torqued
more than once. Replace rotation bolts after 1500 hours / 2 years. Always use replacement bolts of the same size and
class as the one removed. Unless otherwise specified, use class 10.9 metric hex head cap screws, class 10.9 metric flat
head cap screws and class 12.9 metric socket head cap screws. When installing new bolts, ensure that the bolt is clean
and dry.
Note: Some bolts have unique torque specifications. Refer to the LaBounty Parts Manual.
Never use an inferior class fastener. Fastener failure
