6.5 DRAINING OIL BUILD UP FROM THE
PROPANE REGULATOR (PRIOR TO S/N
0300137808)
During the course of normal operation oils may build inside
the primary and secondary chambers of the propane pres-
sure regulator. These oils may be a result of poor fuel quality,
contamination of the fuel supply chain, or regional variation
in the make up of the fuel. If the build up of the oil is signifi-
cant this can effect the operation of the fuel control system.
Refer to Section 6.3, Operator Maintenance for maintenance
intervals. More frequent draining may be required if the fuel
supply has been contaminated.
FOR BEST RESULTS WARM THE ENGINE TO OPERATING TEMPERA-
TURE 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
temperature sensor in the auxiliary fuel port of the EPR.
