Torque Specifications
Metric Hardware
Most of the nuts, bolts, studs, and threaded holes in
your lift truck are metric. In this manual we provide
specifications in both metric and U.S. customary
measurement. Always replace metric hardware with
metric hardware. See the parts books for proper
replacement.
NOTE: For proper fit, use only metric tools on metric
hardware. Non-metric tools might slip and
cause injury.
