How to Procedures
NOTE: If a vehicle is on uneven ground, more fuel may be required.
1. Fill the fuel tank with the recommended grade of fuel. If only partial filling is
possible, add a minimum of 10% of the total tank volume of fuel to the tank.
For example, a 150-gallon tank would require a minimum of 15 gallons of
fuel.
2. Connect ESOC 350 (J-47912) or operate the engine mounted hand primer for
three minutes or 250 strokes.
3. Turn on the ignition switch.
4. Wait for the engine system indicator lights on the instrument panel to go out.
5. With the accelerator pedal in the idle position, start the engine.
6. Crank engine for 20 seconds.
NOTE: The starting cycle can be repeated up to three times.
7. If engine does not start, allow for a 60-second cool down and repeat previous
step.
8. Monitor the oil pressure gauge or indicator lamp. Keep the engine running at
an idling speed until a stable oil pressure reading of 97 kPa (14 psi) or more
is maintained for one minute.
9. Check for leaks.
10. Allow the engine to reach operating temperature of 60° C (140° F).
NOTICE: Increasing engine speed above idle before oil pressure has
stabilized may cause severe engine damage.
