B5.9G, B5.9LPG, B Gas Plus, B LPG Plus, and B Gas International Engines – 101-018   Starting Procedure After Extended Shutdown or Oil Change

Complete the following steps after each oil change, or after the engine has been shut off for more than five days, to be sure that the engine receives oil flow through the lubrication system.

Verify that all sensors are functioning properly prior to engine start. Reset control and clear any inactive faults (using an electronic service tool).

Disconnect the engine position sensor if no pre-lubricating oil pump is installed.

WARNING  Natural gas is highly flammable. Keep all cigarettes, sparks, arching switches and equipment, pilot lights, flames and other sources of ignition out of the work area, and areas sharing ventilation.

Make sure the fuel supply is shut off by turning the supply valve off as shown.

CAUTION  Do not engage the starter motor for more than 30 seconds. Wait two minutes between starter engagements to cool the starter motor.

Rotate the crankshaft using the starter motor until oil pressure appears on the gauge or the warning light goes out.

After oil pressure is observed, open the fuel supply valve.

Connect the engine position sensor.

Start the engine. Refer to Normal Starting Procedures in this section.
