6. FUEL PUMP: To bleed air out of fuel pump, open air bleed valve on side of fuel pump. Turn machine
and burner ON. When fuel looks clear (NOT FOAMING), close air bleeding valve. Air is out of fuel lines
and fuel pump.
A. To check fuel pressure, plumb a 200 PSI guage into the port marked gauge. DO NOT USE BLEED
VALVE PORT TO CHECK FUEL PUMP PRESSURE.
B. To adjust fuel pressure, insert a small flat screwdriver into pressure regulator slot and turn clockwise
to increase pressure and counter clockwise to decrease pressure. One full turn is about 10 PSI.
Use a pressure gauge. normal operating pressure is 140 PSI. DO NOT EXCEED 150 PSI.
C. Service the fuel pump once every 50 hours or 3 mnths by cleaning the fuel strainer screen. A
clogged strainer or fuel filter will cause fuel pump stravation and dry the fuel pump up. The ONLY
lubrication the fuel pump has is the fuel that runs through it. KEEP IT CLEAN for longer fuel pump
life.
