:Fire
Always stop the engine, when working on the fuel line.
Always wipe any drip of Diesel fuel or oil. Do not use this equipment when a leak is found.
Repair the equipment before use.
Ensure that there is no fuel leakage on the fuel line after the fuel line working finished.
Turn the lever for 3-way valve to A position
Disconnect the PT-1/2 plugs from both the external
fuel intake and an external fuel return, and connect
the hoses from an external fuel tank, as shown
below.
Turn the lever for 3-way valve to B position.
Vacuum out the air from connected hoses.
This will allow the use of the fuel from an external fuel
tank.
<Caution>
To vacuum out the air from the fuel line, refer to 9.3
During Operation section.
Use always oil-proof hose in 8-10mm inner diameter
as connecting hose.
The fuel level in the external fuel tank should be 0 to
3m higher than the bottom of the generator.
To avoid any leaks from the external fuel intake and an
external fuel return ports, always turn the lever for
3-way valve to A position.
Use extreme caution when connecting the hoses. If the lever
position is not set properly, the fuel may leak from either the
built-in fuel tank or an external fuel tank.
Set the fuel intake position 15-20mm above from the external
fuel intake bottom line, otherwise water or garbage in the tank
may come into the fuel line.
In order to avoid engine malfunction due to air suction, set the
fuel return at the same level as the fuel intake level in the
external tank.
Just after having connected to external fuel tank, there may be
a case that engine speed is unstable and engine stops due to
insufficient air extraction. Therefore, be sure to confirm that the
air is extracted completely and the engine speeds keeps stable
before leaving the equipment under people-less operation.
