* 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.
