Repeat this step until the relief is set at 2500 psi.
a. Setting relief pressure on selector valve.
i. Loosen the adjustment setscrew jam nut on relief valve using a 9/16-inch
wrench.
ii. Use a 3/16-inch hex wrench and turn relief clockwise to increase pressure and
counter clockwise to decrease pressure.
iii. Pull selector valve lever rearward and check pressure. Repeat adjustment
until 2500 psi is obtained.
iv. Once pressure is obtained, tighten setscrew jam nut with 9/16-inch wrench.
7. Raise incline conveyor to maximum height by moving right lever forward. Release lever and
leave incline conveyor remaining in maximum position. After testing check to see if the incline
conveyor drifts down.
8. Engage operation of conveyor system by moving left selector valve forward. Both conveyors
should be rotating.
9. Verify pressure readings at each gauge.
a. Pressure at lower conveyor pressure line should read between 500 to 1000 psi
b. Pressure on incline conveyor pressure line should read between 500 to 1000 psi.
10. Move hydraulic selector valve back into neutral position.
