3.0 ADJUSTING THE B-PORT RELIEF VALVE
(Retract Pressure Setting)
A separate relief valve limits the maximum B-Port retract
pressure. See Figure 9. Check the retract pressure as described
in steps 1 through 4 of this section. If it is not within allowable
limits, make adjustments as described in steps 5a through 5e.
1. Set the main relief valve (A-Port) pressure to the desired
setting as described in Section 2.1.
2. Be sure that all hydraulic hoses are disconnected from
couplers on valve.
WARNING: Ensure all couplers have the protective
caps fully installed before starting pump.
3. Use the menu button and ARROW keys to change LOCAL
mode to ON.
4. Press and release the ARROW UP button on the keypad.
The pump will start (refer to pump instruction sheet for
complete operating instructions).
5. After releasing the ARROW UP button, check the retract
pressure on the pressure gauge or LCD screen.
Pressure should read 220 BAR +/- 10 BAR"
6. If the retract pressure reading is not within the allowable
range, follow steps a through e, otherwise follow up with
instructions in paragraph 2.1.12 on page7.
IMPORTANT: The B-Port relief valve should be adjusted only by
qualified hydraulic service personnel.
a. Remove acorn nut using a 9/16" socket wrench. This will
expose the adjustment set screw. See Figure 9.
b. Remove copper gasket and loosen jam nut.
c. Using a 5/32" Allen wrench, turn the adjustment set screw
clockwise to increase pressure or counter-clockwise to
reduce pressure (as required).
d. To secure the setting, torque jam nut to 5-6 ft-lbs [6-8
Nm] while holding the adjustment set screw in place with
a 5/32" Allen wrench.
e. Reinstall copper gasket and acorn nut and torque to
5-6 ft-lbs [7-8 Nm] using a 9/16" socket wrench. (Do
not overtighten as threads will strip out). Verify pressure
setting and readjust if necessary.
