Bolt Torque Chart - Woods BATWING BW15.60E Manual De Usuario

Always tighten hardware to these values unless a different torque value or tightening procedure is listed for a specific
application.
Fasteners must always be replaced with the same grade as specified in the manual parts list.
Always use the proper tool for tightening hardware: SAE for SAE hardware and Metric for metric hardware.
Make sure fastener threads are clean and you start thread engagement properly.
All torque values are given to specifications used on hardware defined by SAE J1701 MAR 99 & J1701M JUL 96.
