10.14. Make adjustments to the relief valve in single-
facet increments:
• Loosen the jam nut.
• Make adjustment: 1/6th turn or less.
• Tighten jam nut.
• Install pivot bracket.
• Test relief valve pressure.
• Repeat as necessary.
• DO NOT "crank-up" the pressure beyond 1,500
PSI (103 Bars).
• Install the fenders when adjustment is com-
pleted.
10.15. The pressure readings at both sets of ports
should respond equally to adjustments made to
the relief valve. If there is substantial difference
between the pressures found at the two sets of
ports, there is an internal problem with the
loader valve.
10.16. If the loader valve does not respond to adjust-
ment, or does not perform as described in this
section, replace the valve.
