Connecting With External Fuel Tank - Shindaiwa DGK60D Owner's Manual

9-6. Connecting with External Fuel Tank

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 3way fuel valve lever to the
1
"A" side.
(Position for using the internal tank.)
Remove the plugs(R1/2") from both
2
the external fuel inlet and the
external fuel return.
Connect the hoses from an external fuel tank, as shown below.
3
Turn the 3way fuel valve lever to the "B" side.
4
(Position for using the external tank.)
Bleed air from the external tank connecting hose. Fuel can be
5
supplied from the external tank after completing the above
procedures.
< NOTE >
 If using a hose for the piping, use
oil-resistant hose with an internal
diameter of 0.31 to 0.35 in (8 to 9 mm).
 Set the fuel level of the external fuel tank
so that it is from 0 to 10 ft. (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 0.6 to 0.8 in. (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 "9-3 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.
