Drive the machine to a smooth, horizontal surface.
Illustration 1 g02125547
Move propel lever (3) to the NEUTRAL position.
Rotate speed dial (2) to the MINIMUM position.
Move parking brake switch (1) to the ON position.
Illustration 2 g02125548
Move screed lift switch (4) to the FLOAT position. Move the screed lift switch on the right instrument panel to the FLOAT position.Note: The screed lift switch on both instrument panels must be in the FLOAT position in order for the screed to lower.
After the screed rests on the ground, move screed lift switch (4) to the HOLD position.
Illustration 3 g02125550
Move throttle control switch (5) to the LOW IDLE position. Hold the switch in this position for less than 1 second.
After the engine reaches low idle, move engine start switch (6) to the OFF position.
Illustration 4 g02125552
Open access door (7) on the left side of the machine.
Illustration 5 g02125554
Remove cap from port "G" (8) on the left grade and slope control valve. Install Tool (C) on tap (9) .
Connect Tool (B) to Tool (C). Connect Tool (B) to Tool (A).
Move engine start switch (6) to the START position. Release the engine start switch when the engine starts.
Operate the engine at low idle for a few minutes.
Move throttle control switch (5) to the HIGH IDLE position. Hold the switch in this position for less than 1 second. The engine speed should increase to 2200 rpm.
Illustration 6 g02125557
Monitor the hydraulic oil temperature on the operator display. Operate the machine until the oil temperature reaches 43 5.6 °C (110 10 °F).
Read pressure on Tool (A). The pressure should be 14000 175 kPa (2030 25 psi).
Move throttle control switch (5) to the LOW IDLE position. Hold the switch in this position for less than 1 second.
After the engine reaches low idle, move engine start switch (6) to the OFF position.
If the pressure is within the specified range, go to Step 23. If the pressure is outside the specified range, go to Step 20.
Illustration 7 g02125561
Use a 4 mm hex wrench in order to loosen set screw (9) on the pump control valve.
Use a 6 mm hex wrench in order to manipulate adjustment screw (10). Rotate the adjustment screw clockwise in order to increase the pressure. Rotate the adjustment screw counterclockwise in order to decrease the pressure.Note: One revolution of adjustment screw (10) changes the pressure by approximately 2411 kPa (350 psi).
Hold adjustment screw (10) in place. Tighten set screw (9). Go back to Step 12.
Remove the tooling.
Close access door (8) .
