Torque gures indicated above are valid for non-greased or non-oiled threads and heads unless oth-
erwise specied. Therefore, do not grease or oil bolts or capscrews unless otherwise specied in this
manual. When using locking elements, increase torque values by 5%.
* Torque value for bolts and capscrews are identied by their head markings.
