Port Relief
NOTE
To get proper pressure from the Port Reliefs, it may be necessary
to turn the POR inward on the implement pump. See Figure 2 on
Page 1 for POR location on implement pump.
Port Reliefs should be 500 psi higher than the working pressure
in the valve section.
EXAMPLE
If the implement pump valve LS Relief pressure is 4200 psi, set
the Port Relief pressure to 4700 psi.
3. Back out the Port Relief until the needle on the gauge starts to move and
tighten the jam nut once the relief is properly
set. See Figure 1 above.
4. Reset the Pump POR and LS settings as necessary.
