5. After Step 4, slowly operate a hydraulic function that will demand approximately half flow from the
pump, but keep outlet pressure below the power control pressure starting point (if Power control is
used). Danfoss recommends loading the outlet pressure to 50bar.

Warning
Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing
serious injury and/or infection. Relieve pressure in the system before removing hoses, fittings,
gauges, or components.
Unintended movement of the machine or mechanism may cause injury to the technician or
bystanders. To protect against unintended movement, secure the machine or disable / disconnect
the mechanism while servicing.
C
Caution
Contamination can damage internal components and void the manufacturer’s warranty. Take
precautions to ensure system cleanliness when removing and reinstalling system lines.
6. Loosen the LS control lock nut. While watching the pressure gauges, turn the LS control adjusting
screw counterclockwise until the desired pressure differential between port MB and port X is
achieved (LS setting). Clockwise rotation increases the setting, counterclockwise rotation will
decrease it; approximate gain (see Table 1) per turn. While holding the position of the LS adjusting
screw, torque the LS lock nut to 21.6~24.6 N•m [191-218 lbf•in].
7. Stop the prime mover, remove the pressure gauge and flow meter, and return the system to its
normal operating configuration.
