FUEL TANK CONNECTION
1. Set the fuel cock to the
OFF
position.
2. Connect the suction hose to the fuel filter. Use a suction
hose with an inner diameter of 7 mm and attach a hose
clamp so that there is no leak in the connection.
3. Connect the return hose to the engine. Use a return
hose with an inner diameter of 4 mm and attach it with
a hose clamp so there is no leak in the connection.
4. Set the fuel cock to the
ON
position and make sure
there is no fuel leaking at the joints.
5. Loosen the bolt at the inlet of the injection pump and
remove the air inside the piping.
6. Tighten the bolt when all of the air has come out and
the fuel starts to overflow.

NOTICE
This generator does not have an internal fuel tank. An
external fuel tank needs to be connected.
Make sure the external fuel tank is positioned higher
than the engine, or pump the fuel to the engine using
a fuel pump.
DANGER
Motor fuels are highly flammable and can
be dangerous if mishandled.
DO NOT
smoke while refueling.
DO NOT
attempt
to refuel if the engine is hot!, running or
in the dark.
INSPECTION/SETUP
COOLANT (ANTIFREEZE)
Kubota recommends antifreeze/summer coolant for use in
their engines, which can be purchased in concentrate (and
mixed with 50% demineralized water) or pre-diluted. See
the Kubota Engine Owner’s Manual for further details.
Day-to-day addition of coolant is done from the recovery
tank (Figure 11). When adding coolant to the radiator,
DO NOT
remove the radiator cap until the unit has
completely cooled. See Table 7 for engine, radiator, and
recovery tank coolant capacities.
1. Verify that the coolant level in the coolant recovery tank
is between the
FULL
and
LOW
markings as shown in
Figure 11. Coolant Recovery Tank
WARNING
When adding coolant/antifreeze mix to the
radiator,
DO NOT
remove the radiator cap
until the unit has completely cooled. The
possibility of hot coolant exists which can
cause severe burns.
NOTICE
Normally, only the coolant level in the recovery tank
needs to be checked. However, the radiator cap should
be opened once a week to verify that coolant is visible
(full) in the radiator.
