*Check torque at whichever interval occurs first.
To check GRADALL torque values, set the torque wrench at 95% of rated torque value and check fastener. If the
torque wrench releases before the fastener moves, assume fastener torque is correct. When setting GRADALL
torque values, use the values given on the following chart. Do not exceed allowances.
