Install a 148-8327 Connector As to the "B" port of the stick valve. Connect the 148-8327 Connector As to the hose from the outlet of the portable hydraulic tester.
Release the pressure in the hydraulic system.
Ensure that the harness is disconnected from the solenoid on the pump.
Open the flow meter.
Start the engine. Move the stick joystick fully to the STICK OUT position.
Operate the hydraulics until the 4C-9910 Portable Hydraulic Tester indicates an operating temperature of 65° 5°C (149° 9°F).
Move the accelerator lever to 2100 50 rpm.
Adjust the needle valve so that the discharge pressure on the pressure gauge at test port (5) is 11500 300 kPa (1668 44 psi).
The display on the 4C-9910 Portable Hydraulic Tester should indicate a flow of 80 L/min to 115 L/min (21 US gpm to 30 US gpm).

If the flow in Step 18 is not correct, remove cap (30). Loosen locknut (29). Turn screw (32) in order to ensure that inner spring (27) is under no pressure. Do not remove screw (32) .
Loosen the locknut (28). Turn adjuster (31) .Note: When you turn the set screw clockwise, the torque is increased. When you turn the set screw counterclockwise, the torque is decreased.
Secure set screw (31) with locknut (28). Connect the harness to the solenoid that is on the pump.
Adjust the needle valve so the discharge pressure is 23000 300 kPa (3350 44 psi).
The display on the 4C-9910 Portable Hydraulic Tester should indicate a flow of 95 L/min to 125 L/min (25 US gpm to 33 US gpm).
If the flow in Step 23 is not correct, adjust set screw (32) .Note: When you turn the set screw clockwise, the torque is increased. When you turn the set screw counterclockwise, the torque is decreased.
Secure set screw (32) with locknut (29) .
Move the accelerator lever to low idle. Turn off the engine. Release the pressure in the hydraulic system.
Remove all the test equipment.
After you complete the tests and the machine is operating within specifications, the machine can
