DRAINING OIL BUILD UP FROM THE PROPANE

REGULATOR

During the course of normal operation, oils may build
inside the primary and secondary chambers of the pro-
pane pressure 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 significant this can effect the operation of the
fuel control system. Refer to Section 5.4, Operator Mainte-
nance, for maintenance intervals. More frequent draining
may be required if the fuel supply has been contaminated.
NOTICE
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.
