OPERATION
TROUBLES AND ACTIONS
RUNNING OUT OF FUEL
When starting the engine again after running out of fuel, fill with fuel, then bleed the air from the fuel system before
starting the engine.
Always watch the fuel level and be careful not to run out of fuel.
If the engine has stopped because of lack of fuel, it is necessary to use the priming pump to bleed the air com-
pletely from the fuel circuit.
Procedure for Bleeding Air
This engine consists of higher precision parts than on the conventional fuel injection pump and nozzle, so
if dirt gets in, it will cause problems. If there is any dirt stuck to the fuel line, use fuel to wash it off com-
pletely.
Be careful when opening the air bleed plug at the fuel filter head. The system is still under pressure and
fuel may spurt out.
1. Loosen air bleed plug (A) at the fuel main filter head (1).
2. Loosen wing nut (4) holding lever (3) of priming pump (2).
3. Push in lever (3) repeatedly.
Check that bubbles come out with the fuel from air bleed
plug (A).
4. Tighten air bleed plug (A).
Tightening torque: 4.9 to 6.9 Nm (0.5 to 0.7 kgm)
5. Tighten wing nut (4) securely to lock lever (3) in position.
Target tightening torque: 11.8 Nm (1.2 kgm)
6. Turn the key in the starting switch to the START position
and start the engine.
When doing this, do not crank the starting motor continu-
ously 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.
7. If the engine does not start, repeat the operation from Step
1.
