Torque Specifications
Metric Hardware - This lift truck is almost totally
metric design. Specifications are given in metric
and U.S. Customary measurement. Metric
hardware must be replaced with metric hardware.
Check parts books for proper replacement.
Use only metric tools on most hardware for proper
fit. Other tools could slip and possibly cause injury.
