Remove the cap from charge pressure tap (19) on the right propel pump. Connect third Tool (A2) to the pressure tap. Test Procedure
Move machine power switch (10) to the START position.
Press push to start switch (7) for 2 seconds in order to start the engine. An LED next to the push to start switch will flash when the engine is in start mode. When the engine has started, the LED will remain illuminated. Note: Only one attempt to start the engine is allowed per key cycle. A new key cycle is necessary in order to restart the process.
Operate the engine at low idle for a few minutes.

Squeeze trigger (24), and move propel lever (4) to the FULL FORWARD position.
Record the pressure at port "M1" (17).
Record the pressure at charge pressure tap (19). Note: This pressure should be 2425 175 kPa (352 25 psi). If this pressure is outside specification, charge pressure must be adjusted. Refer to AP655F Paver Propel System Operations, Testing and Adjusting, "Relief Valve (Charge) Test and Adjust (Right Pump)".
Subtract the pressure that was recorded in Step 11 from the pressure that was recorded in Step 10. The pressure differential should be 42000 1400 kPa (6090 200 psi).
Move propel lever (4) back to the NEUTRAL position.
Squeeze trigger (24), and move propel lever (4) to the FULL REVERSE position.
Record the pressure at port "M2" (18).
Record the pressure at charge pressure tap (19).
Move propel lever (4) to the NEUTRAL position.
Subtract the pressure that was recorded in Step 16 from the pressure that was recorded in Step 15. The pressure differential should be 42000 1400 kPa (6090 200 psi).
Move speed dial (23) back to the MINIMUM position.
Press parking brake switch (3) in order to change the status of the parking brake to "engaged". When the parking brake status is "engaged", an LED next
