Fuel Control System:
This machine utilizes a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combus-		5/16"
tion chamber. The solenoid, which is normally closed,
is activated by a flow switch when water flows through
it. When the operator releases the trigger on the spray		Nozzle
gun, the flow of water through the flow switch stops,		1/16"
turning off the electrical current to the fuel solenoid.
The solenoid then closes, shutting off the supply of fuel	Top View	Side View
