BRAKE VALVE TROUBLESHOOTING

FAILURE MODE:	CHECK STEPS
- MOWER WILL NOT START - system pressure is low
(engine not lugging).	1 thru 6
- MOWER WILL NOT START - system pressure is high
(engine lugging). “MR” port will be high pressure.	7
- MOWER WILL NOT ROTATE AT FULL SPEED - limited power.	3 thru 5
- MOWER BLADE WILL NOT STOP - blade will not stop in proper time.	7 thru 9

CORRECTIVE STEPS:

1.Check for voltage at solenoid (item 6), voltage must be between 10.2 volts and 13.8 volts.

2.Remove, inspect solenoid and cartridge (items 4, 6) for wear or contamination.

3.Remove, inspect logic elements near “P” port (item 3) for wear or contamination.

4.Remove, inspect 3000 psi relief valve (item 2) for wear or contamination.

5.Remove and inspect orifices near “P” port for contamination.

6.Remove “P” port hose and fitting, visually inspect for contamination, check ball for movement.

7.Remove and inspect orifices near “MR” port for contamination.

8.Remove, inspect 2600 psi relief valve (item 5) for wear of contamination.

9.Remove, inpect logic element near “MR” port (item 3) for wear or contamination.
