HYDRAULIC PRESSURE ADJUSTMENT CONTINUED...
L90 LOWER VALVE BANK ADJUSTMENTS (558-01627)
Sections with Feed Reducers:
Sections 1 and 3 are equipped with adjustable feed reducers to control pressure. When making adjustments on
the feed reducers, install a gauge on the load sense test port located on the pump. These feed reducers are pre-
set to 1800 PSI. To decrease the pressure, remove the plastic caps on the feed reducers, loosen the lock nut with
a 10 mm wrench and turn the adjustment screw out (counterclockwise) with a 3 mm Allen wrench.
Sections without Feed Reducers:
To adjust the pressure, install a gauge on the load sense test port located on the pump. Adjust pressure at the
load sense adjustment screw on the load sense relief on the valve bank inlet cover. Pressure should be 2800 PSI.
