Open the engine access door on the right side of the machine in order to access the fuel priming pump. The fuel priming pump is located above the primary fuel filter.
Turn the priming pump plunger counterclockwise and pull out the priming pump plunger. Operate the priming pump plunger until resistance is felt. This indicates that the fuel filter is full of fuel.
Push the priming pump plunger inward and turn clockwise in order to lock the priming pump plunger.
Start the engine. Look for leaks around the fuel filter assembly. If the engine does not start, or if the engine misfires, more priming is necessary.
