3. The crane has minimum hydraulic requirements. See General Dimensions.
4. Vehicle shall meet minimum GVWR dependent on crane model:
5. The vehicle must be equipped with an engine speed control and tachometer.
6. Ensure the mounting surface is properly reinforced to withstand the capacity loading of the crane. Ensure the
outriggers are used to provide total stability for the truck.
7. Cut the proper sized hole in the mounting location (centered with mounting bolts) for access to hydraulic
connections.
8. Ensure the mounting bolts are the proper size and grade. Tighten to the correct specification. See General
