AFTER RUNNING OUT OF FUEL

If you have run out of fuel, add fuel to the fuel tank and bleed air from the fuel system and then start the engine.
PROCEDURE FOR BLEEDING AIR
The fuel injection pump and nozzle of this engine consist of more precise parts than the conventional ones. If foreign matter
enters them, it can cause a trouble. Accordingly, if dust sticks to the fuel system, wash it off with clean fuel.
When opening the air bleeding plug at the fuel filter head, take care. Fuel may spout because of residual pressure.
1. Fill the fuel tank with fuel.
2. Loosen air bleeding plug (1) at the fuel main filter head.
Do not loosen the plug at the filter stand of the fuel prefilter. If
it is loosened, air is not bled.
3. Loosen wing bolt (3) which is fixing lever (4) of priming pump
(2). Move lever (4) up and down to let fuel flow out of air
bleeding plug (1) until bubbles do not come out any more.
4. Tighten air bleeding plug (1) and then tighten wing bolt (3) of
priming pump (2) securely to lock lever (4).
Tightening torque for air bleeding plug
7.8 to 9.8Nm{0.8 to 1kgm}
Tightening torque for wing screw
6.9 to 12.7Nm{0.7 to 1.3kgm}
5. Turn the key in the starting switch to the START position and
start the engine.
When doing this, do not crank the starting motor continuously
for more than 20 seconds. If the engine does not start, wait for
at least 2 minutes, then try again. Perform this operation a
maximum of 4 times.
6. If the engine does not start, repeat the procedure from Step 2.
