IMPORTANT NOTICE ON USE OF TORQUE WRENCHES
Never forget that tightening of screws and nuts with torque wrenches to the recom-
mended torques, must always be performed with threads and seating faces (screw or
nut head seating faces, lockplates, washers, etc.) absolutely dry, perfectly free from
any trace of rust, grease, dirt, etc.
NOTE - Tightening directions for self-locking nuts are outlined on page 154.
