CAUTION : FIRE
 Always make sure that the engine is stopped 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 3 way valve toward position "A".

(to supply fuel from the internal tank.)
Remove the connecting hose from the
2
3 way valve.

Remove the plate.
Pass the fuel hose from the external tank
4
through the inlet for the external fuel
supply and connect the inlet and outlet
valve in the 3 way valve.
Turn the 3 way valve lever to the position

external tank. Steps to supply fuel from
the external tank completed.
< 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 3 way 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.
 Extend the supply side outlet 15 to 20 mm above the bottom of the external tank in
order to prevent foreign material or water from being suctioned.
 Set the external fuel tank return side inlet as 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.(2) Adjustment 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.
