Draining Oil Build Up From The Propane Regulator
(Prior to S/N 0300134626)
During the course of normal operation oils may build
inside the primar y and secondar y chambers of the
propane 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 1.7, Maintenance and
Lubrication for maintenance intervals. More frequent
draining may be required if the fuel supply has been con-
taminated.
FOR BEST RESULTS WARM THE ENGINE TO OPERATING TEMPERATURE 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.
5.
Disconnect the electrical connection to the LPG fuel
temperature sensor in the auxiliary fuel port of the EPR.
6.
Remove the retainer clip for the LPG fuel temperature
sensor and remove the sensor from the regulator body.
NOTE:
Have a small container ready to collect oil that will drain
freely from the regulator at this point.
7.
Once all of the oil has been drained, reinstall the LPG
fuel temperature sensor and reconnect the electrical
connector.
8.
Open the fuel tank manual valve.
9.
Start the engine and verify all connections are secure.
10.
Dispose of any drained oil in a safe and proper fashion.
