When "Piston Pump Neutral Test" (19) is in "Enabled" mode (21), the Plus+1TM program is launched.
Read differential pressure on Tool (A). The pressure differential should be less than 150 kPa (22 psi). If the differential pressure is less than 150 kPa (22 psi), go to Step 55. If the pressure is not within 150 kPa (22 psi), go to Step 30.
Move parking brake switch (2) to the ON position.
Move engine start switch (4) to the OFF position.
Disconnect Tool (J) from Tool (F) in port "M5" (10). Disconnect other end of Tool (J) from Tool (F) in port "M4" (11) .
Assemble the tooling. Connect one Tool (B) to each Tool (D). Make two sets of Tool (D) and Tool (B). Connect both sets of Tool (D) to Tool (A) .
Connect one Tool (D) to Tool (F) in port "M5" (13) .
Connect other Tool (D) to Tool (F) in port "M4" (14) .

Remove lock-screws (26) and lock-plates (27) from servo cylinder cap (25) for the "M4" servo cylinder.
Using a 3/4" deep socket, unthread servo cylinder cap (24) and servo cylinder cap (25) two to three turns. This action will ensure that the servo cylinder caps are not in contact with the servo piston.
Move engine start switch (4) to the START position. Release the switch when the engine starts.
Use throttle control switch (3) in order to operate the engine in ECO mode or in low idle.Note: Two things indicate when the engine is in ECO mode. First, "ECO" will appear on the display. Second, the second LED next to throttle control switch (3) will be illuminated. Two things indicate when the engine is at low idle. First, "Low Idle" will appear on the display. Second, the first LED next to the throttle control switch will be illuminated.
Move parking brake switch (2) to the OFF position.
Launch the Plus+1TM program on the computer. Enable the "Piston Pump Neutral Test".

Note: A small movement of the adjustment mechanism is all that will be required. Larger movements may cause machine movement.
Loosen locknut (28) and rotate adjustment screw (29). Note the pressure at port "M4" (14) and port "M5" (13). Rotate adjustment screw (29) until the servo pressure at port "M4" is 95 - 200
