7. Low Fuel Shutdown Assembly
A. Description
The low fuel shutdown assembly, when requested as an option by a customer, may be used with all
generator set specifications covered by this manual. It is identified by Hobart Part Number 285953 .
Its purpose is to stop the engine when the fuel level in the fuel tank becomes low before the unit runs
out of fuel. A liquid-level detector, mounted in the fuel tank, opens the power to the engine fuel valve
solenoid when fuel drops to a predetermined level in the fuel tank.
NOTE: Fuel tank MUST be refilled after a low-fuel shutdown before engine can be restarted.

ure 7 shows where the low fuel sensor is installed on the fuel tank. Engine schematic diagram
