6.5 DRAINING OIL BUILD UP FROM THE PROPANE
REGULATOR (PRIOR TO S/N 0300109274)
During the course of normal operation oils may build inside the
primary and secondary chambers of the propane pressure regu-
lator. These oils may be a result of poor fuel quality, contamina-
tion of the fuel supply chain, or regional variation in the make up
of the fuel. If the build up of the oil is significant this can effect the
operation of the fuel control system. Refer to Section 6.3, Opera-
tor Maintenance for maintenance intervals. More frequent drain-
ing may be required if the fuel supply has been contaminated.
FOR BEST RESULTS WARM THE ENGINE TO OPERATING TEMPERATURE BEFORE DRAINING.
THIS WILL ALLOW THE OILS TO FLOW FREELY FROM THE REGULATOR.
1. Move the equipment to a well ventilated area. Ensure there
are no external ignition sources.
2. Start the engine and bring to operating temperature.
3. With the engine running, close the manual tank valve and
run the engine out of fuel.
4. Push in the Emergency Switch once the engine stops.
5. Disconnect the electrical connection to the LPG fuel temper-
ature sensor in the auxiliary fuel port of the EPR.
