AUXILIARY FUEL TANK OPTION
The auxiliary fuel tank option is designed so the unit can run from an external
fuel tank. The unit is still programmed to shut down when the internal tank’s
fuel level drops below 5%. In order for the unit to run off of an auxiliary tank,
the fuel level in the internal tank must remain over 5%. To operate the unit using
an auxiliary fuel tank, use the following procedure:
1. Shut down the unit and check that the level of fuel in the tank is above 5%.
2. Attach the auxiliary fuel tank's fuel lines to the “AUXILIARY FUEL INLET”
and “AUXILIARY FUEL OUTLET” fittings on the unit.
3. Open the “AUXILIARY FUEL INLET” and “AUXILIARY FUEL OUTLET”
valves located above the fuel fill cap behind the lift structure.
FUEL TRANSFER PUMP OPTION
The fuel transfer pump option allows the fuel tank to be refilled from an external bulk
fuel source. When the fuel transfer switch is on, anytime the fuel level drops below 15%
the fuel transfer pump will begin pumping fuel from an external bulk fuel source into the
fuel tank on the unit. The fuel transfer pump will shut off when the fuel level of the internal
tank reaches 90%. The pump will also be monitored to ensure a certain percentage
increase in fuel level over a given period of time to prevent the pump from running dry.
To operate the fuel transfer system, use the following procedure:
1. Shut down the unit.
Note:
If the external bulk fuel supply is already connected, the unit does not have to be
shut down to turn the fuel transfer pump option on or off.
2. Attach the external bulk fuel supply to the “FUEL TRANSFER INLET” fitting on the unit.
3. Turn on the fuel transfer switch.
VISCOUS FAN CLUTCH OPTION
The viscous fan clutch option allows the engine cooling fan to engage at lower speeds and disengage at higher
speeds, increasing cooling system efficiency. The cooling fan will engage at full speed when the coolant temperature
rises. When the fan is operating at full speed, it will switch to a slower speed when the coolant temperature drops.
There will be an audible difference when the engine cooling fan switches speeds. Depending on unit model, the
temperature ranges vary between 170-200ºF (77-93ºC).
