Installer must identify the pressure port of the supply valve prior to connection to the grapple's
main control valve. Failure to do so may result in severe internal damage to the valve.

For each auxiliary valve used, do the following (see schematic):
• Adjust flow rate (auxiliary valve).

• Adjust system relief pressure at valve inlet section.
• Adjust pump pressure (auxiliary valve).
