ENGINE AR 2W7067 - Caterpillar

Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. To help prevent possible injury, turn the start switch off when changing fuel filters or water separator elements. Clean up fuel spills immediately.
Illustration 1 g01182169 (1) Priming Pump Priming the fuel system fills the fuel filters. Priming the fuel system also removes air from the fuel system. This procedure is used primarily when the engine runs out of fuel.
Unlock the fuel priming pump by turning the handle counterclockwise. Move the plunger for the fuel priming pump in and out until a strong pressure is felt on the fuel priming pump and until the check valve clicks. This procedure will require considerable strokes. Lock the fuel priming pump.
Crank the engine after the system is pressurized.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
If the engine does not start, repeat Steps 1 and 2 in order to start the engine.
