9-5. Connecting with External Fuel Tank

CAUTION : FIRE
 Always make sure that the Power Switch is OFF position when working on
piping.
 Always be sure to wipe up any spilled fuel.
 After working on the piping, check that there is no fuel leakage.
Turn the 3way fuel valve lever to the "A"
1
side. (Position for using the internal
tank.)
Remove the connecting hose from the
2
3way fuel valve.
Remove the plate.

Pass the fuel hose from the external
4
tank through the external fuel ports and
connect to the external tank fuel
inlet/return of the 3way fuel valve.
Turn the 3way fuel valve lever to the "B"
5
side. (Position for using the external
tank.)
Bleed air from the external tank
6
connecting hose. Fuel can be supplied
from the external tank after completing
the above procedures.
< Note >
 Protect the piping connecting the external fuel tank and this generator with corrugate tubing or
similar in order to prevent interference between the generator internal parts and the external
fuel ports.
 If using a hose for the piping, use oil-resistant hose with an internal diameter of 8 to 9 mm.
 Set the fuel level of the external fuel tank from 0 to 3 m from the underside of this generator.
The fuel level of the external fuel tank being lower than this generator will result in poor engine
operation or stoppage.
 Turn the 3way fuel valve lever to the "A" side in order to
prevent fuel from flowing out from the external tank fuel
inlet/return.
 Turn the lever completely as far as possible. If the lever
is not completely pressed to either side, it might not be
possible to supply fuel causing the engine to stop.
 Set the supply side so that it is 15 to 20 mm above the
underside of the tank in order to prevent foreign material
or water from being suctioned from inside the external
fuel tank.
 Set the external fuel tank return side at the same height as the supply side in order to prevent
poor engine operation due to air mixed in with the fuel.
 Refer to section "9-2 Procedures during Operation" for air bleeding.
 Some air may remain in hoses or pipes immediately after connecting the external fuel tank
resulting in unstable engine speed and engine stoppage.
 Do not leave the generator unattended for unmanned operation until you have confirmed that
the engine speed is stable.
