2. Open the front engine access door on the right side of the machine. Locate the switch for the fuel priming pump above the primary fuel filter.

3. Move the switch for the electric fuel priming pump to the ON position. Operate the fuel priming pump enough to fill the fuel lines and the fuel filters with fuel before turning "OFF".

   Note: As the air is purged from the fuel system, fuel pressure will increase. Listen for the priming pump to come under load. Continue priming the fuel system until the pump is under load.

4. Return the switch for the fuel priming pump to the OFF position.

   NOTICE
   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.

5. Start the engine. If you cannot start the engine, the engine needs more priming. If the engine continues to misfire or to smoke, more priming is necessary.

   Note: The electric fuel priming pump will only operate if the engine start switch key is in the OFF position. Shut off the engine before any additional priming.

6. Run the engine at the LOW IDLE position until the engine runs smoothly.

7. Close the engine access door.

Reference: If the engine does not start after several attempts, consult your Cat dealer.
