Note: Ensure that the spark plug tubes are seated before installing the spark plugs. If the tubes were removed, reinstall them before installing the spark plugs.

14.Reinstall the spark plug. Do not bump the electrode against the cylinder head. Rotate the spark plug clockwise until you feel resistance.

15.Use a torque wrench to torque each spark plug to 18 Nm (13.3 ft. lbs.). Otherwise, hand-tighten the spark plug until you feel resistance.

16.Use a ratchet wrench to tighten an additional 1/4 turn. Do not overtighten, as doing so may strip the threads or alter the electrode gap setting.

17.Check the spark plug wire connector in the boot for accumulated dirt, grease, and other debris, and clean as necessary.

18.Firmly push the spark plug boot onto the spark plug.

19.Reconnect the generator set engine starting battery, negative (--) lead last.

20.Reconnect the power for the battery charger.
