REV 11/05; 12/05; REV 04/06
Troubleshooting
1. The air hose is connected to the TOE but it does not operate.
Verify that the air compressor is turned on and running.
Check the air pressure regulator at the air compressor, it should be 90 PSI.
2. The hoses are connected but no oil flow is viewed from the View Flow tubes, even
with higher air pressure.
Verify the correct settings of the Fuel Pressure-Recycle Control knob and the Filling-
Recycle Reverse Control knob.
3. The hoses are connected but no oil flow is viewed from the View Flow tubes, even
with higher air pressure, and the engine running.
Check to see if the direction of the oil inlet and oil return hoses are reversed.
