CHECKING BOLT TORQUE
The tables shown below give correct torque values for various bolts and capscrews. Tighten all bolts to the torques
specified in chart unless otherwise noted throughout this manual. Check tightness of bolts periodically, using bolt torque
chart as a guide. Replace hardware with the same strength bolt.
