Note!
To check Gradall torque values, set
the torque wrench of 95% of rated
torque value and check the
fastener. If the torque wrench
releases before the fastener moves,
assume that fastener torque is
correct. When setting Gradall
torque values, use values given on
the chart, not exceeding
allowances.
