2. With engine running at low idle, dead-head in
both directions the auxiliary hydraulics functions.
Indicated system pressure should be 3000 psi
for both directions.
3. If reading is different than 3,000 psi, adjustment
is required.

▪
Auxiliary Hydraulics Port B
1. Loosen the lock nut on the pressure reducing
valve at port RV3 on the Main Manifold.
2. With engine running at low idle, turn the
adjustment screw clockwise (CW) to increase
the pressure reading and counter-clockwise
(CCW) to reduce the pressure reading until
desired reading is achieved.
3. Tighten the lock nut on the valve RV3 and re-
check the reading to ensure that the correct
pressure is maintained.
▪
Auxiliary Hydraulics Port A
1. Loosen the lock nut on the pressure reducing
valve at port RV2 on the Main Manifold.
