Slowly move the swing joystick for a full SWING RIGHT operation and check the pressure for relief valve (7) at pressure tap (2). Refer to Table 1 for swing relief pressure.
Return the joystick to the NEUTRAL position.
Slowly move the swing joystick for a full SWING LEFT operation and check the pressure for relief valve (10) at pressure tap (2). Refer to Table 1 for swing relief pressure.
Return the joystick to the NEUTRAL position.Adjustment Procedure
To adjust the swing relief valve, loosen the locknut and turn the adjustment plug until the pressure reading at pressure tap (2) is within the specification. Turning the adjustment plug clockwise increases the pressure. Turning the adjustment plug counterclockwise decreases the pressure.Note: Always make final pressure adjustments on pressure rise.
Tighten the locknut to a torque of 117 10 N m (85 7 lb ft).
