Joystick (front switch)
Disable the hydraulic modulation control, if equipped. Press the front switch on the right joystick in order to deactivate hydraulic modulation.
The air conditioning should be turned off for the following test.
In order to check the line relief valve pressure setting of the stick cylinder head end, move the joystick for the stick until the stick is at the full STICK OUT position (full retraction of stick cylinder). Hold the joystick for the stick in this position.
Check the pressure reading for the stick cylinder head end at the load sensing signal pressure tap.
Return the joystick for the stick to the NEUTRAL position.
The pressure reading should be within the specification. Refer to Table 2. If the pressure reading at the load sensing signal pressure tap is not within the specification, refer to "Adjustment Procedure" in order to adjust the line relief valve for the stick cylinder rod end. Adjustment Procedure

Personal injury or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.
In order to adjust line relief valve (12) for the stick cylinder rod end, loosen locknut (11) and turn adjustment screw (10) until the pressure reading at the load sensing signal pressure tap is within the specification. Refer to Table 2. Note: Turn adjustment screw (10) clockwise in order to increase the pressure. Turn adjustment screw (10) counterclockwise in order to decrease the pressure.Note: Always
