When servicing and disassembling the fuel system, or when fuel has run out air must be bled from the fuel. See the following for the procedure.

1. Fill the fuel tank with fuel.

1. Squeeze the fuel hand primer (A) and operate it 40 to 50 times. Operate the fuel hand primer until it becomes hard.

1. Stop bleeding when the fuel hand primer becomes hard and start the engine.

1. Accelerate the engine for about 3 times, then check that idle speed is stable.

1. If the engine does not start, operate the hand primer again until it becomes hard.
   NOTE: Note that the continuous cranking time of the engine must be 30 seconds to shorter at one operation. Cranking the engine for longer than 30 seconds can cause damage to the starter and fuel pump.
