B5.9G, B5.9LPG, B Gas Plus, B LPG Plus, and B Gas International Engines – 101-014   Normal Starting Procedure

CAUTION  To prevent damage to the starting motor, do not engage the starting motor for more than 30 seconds. Wait two minutes between each attempt to start (electrical starting motors only).

1. Check for free throttle operation.
2. Disengage the driven unit, or if equipped, put the transmission in neutral.
3. Position the fuel shutoff, electrical switch, or mechanical control to the RUN position.
4. With the accelerator pedal or lever in the idle position, Turn the keyswitch to the ON position.

With the keyswitch in the ON position, the engine indicator lamps will come on momentarily and then go out.

If any of the lamps remain on or begin to flash, reference the following procedure. Refer to Procedure 101-048 in Section 1.

CAUTION  The engine must have adequate oil pressure within 15 seconds after starting. If the WARNING lamp indicating low oil pressure has not gone out or there is no oil pressure indicated on the gauge within 15 seconds, shut off the engine immediately to avoid engine damage.

If the engine does not start after three attempts, check the fuel supply system.

Engine oil pressure must be indicated on the gauge within 15 seconds after starting. If oil pressure has not registered within 15 seconds, shut off the engine immediately to avoid engine damage. Check the engine oil level.

Idle the engine 3 to 5 minutes before operating with a load.

CAUTION  Do not operate the engine at low idle for long periods with the engine coolant temperature below the minimum specification found in the Maintenance Specifications in Section V.

Operating the engine at low idle for long periods can result in, but is not limited to, the following conditions:

• Carbon build-up in the cylinder
• Cylinder head valve sticking
• Reduced performance.

WARNING  Batteries can emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To reduce the possibility of arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.

CAUTION  When using jumper cables to start the engine, make sure to connect the cables in parallel: Positive (+) to positive (+) and negative (-) to negative (-). When using an external electrical source to start the engine, turn the disconnect switch to the OFF position. Remove the key before attaching the jumper cables.

CAUTION  To reduce the possibility of damage to engine parts, do not connect jumper starting or battery charging cable to any fuel system or electronic component.

This illustration shows a typical parallel battery connection. This arrangement doubles the cranking amperage.

NOTE: Always reference the relevant OEM literature for jump starting procedures. Failure to follow correct procedures can result in damage to the ECM and other electrical equipment.

This illustration shows a typical series battery connection. This arrangement, positive (+) to negative (-), doubles the voltage.

NOTE: Always reference the relevant OEM literature for jump starting procedures. Failure to follow correct procedures can result in damage to the ECM and other electrical equipment.
