REPAIR & ADJUSTMENTS
pump #2 should be adjusted where approx. inch of adjustment screw threads are ex-
posed outside of the jam nut when the jam nut is locked in place (the max-volume
control adjustment is the one closest to the reservoir) and (b) The adjustment screw
of the min- volume control of pump #2 should be adjusted where approx. inch of
adjustment screw threads are exposed outside of the jam nut when the jam nut is
locked in place. (The min-volume adjustment is on the opposite side of the pump
controller from the max- volume control).
2. Start the hydraulic unit and remove control relay CR10 from its relay base.
(Removing CR10 will close the bypass valve.)
3. Adjust the pump #1 compensator adjustment screw (hex head bolt on side of com-
pensator) inward and watch gauge #11 for increasing pressure. When you determine
that the pump pressure is responding to your adjustment you need to turn the adjust-
ment screw counterclockwise until you have lowered the pressure to 450 PSI and
set the jam nut in place.
Note: Gauge #11 is located adjacent to the discharge port of pump #1
4. Use the manual override and energize control relay CR16 that will activate the pump
#1 solenoid control valve. While control relay CR16 is energized, adjust the pump
pressure control valve (located on the pump #1 controller) either clockwise to in
crease or counter clockwise to decrease until the pressure reading on gauge #11 is
650-700 PSI. Lock the jam nut.
5. Loosen the jam nut on the system relief valve (located in the subplate supporting
valve #28). Using the manual override, energize control relay CR17 and keep it en-
ergized while you adjust the system relief valve (clockwise to raise or counter
clockwise to lower) to a pressure setting of 2900 PSI.
Note: You can observe system pressure on gauge #23 located next to the pressure
switches mounted on the upper right end of the reservoir.
6. With the system pressure gauge holding 2900 PSI, loosen the lock screw on the pres-
sure switches and adjust the switches to the setting where the contacts will make on
rising pressure at 2900 PSI and lock the setting. (You may want to raise and lower
