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 gauge 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 months by cleaning the fuel strainer screen. A clogged strainer or fuel filter will cause fuel pump starvation 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.
WINTERIZING
1.Shut off and disconnect the water supply.
2.Drain float tank.
3.Install antifreeze kit (available through local dealer.)
4.Remove nozzle from wand, and insert pick up hose and soap line into a bucket of 50% solution of antifreeze. Pump antifreeze through machine. Open and close trigger gun a few times to winterize unloader system. When antifreeze flows from the wand, shut the pump off. Disconnect antifreeze kit.
NOTE: BEFORE attempting to wash ANY painted surface, pump
