CHECKING BOLT TORQUE:

in chart unless otherwise noted. Replace hardware with the same strength bolt.
Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise specified. Therefore, do not grease or
oil bolts or capscrews unless otherwise specified in this manual. When using locking elements, increase torque values by 5%.
