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
1.11, Operator Maintenance for maintenance intervals.
More frequent draining may be required if the fuel sup-
ply has been contaminated.
FOR BEST RESULTS WARM THE ENGINE TO OPERATING TEM-
PERATURE BEFORE DRAINING. THIS WILL ALLOW THE OILS TO
BE LIQUID AND 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.
