After installation, the primer bulb functions as follows:

• Priming the Engine: Before attempting to start a cold engine, press the primer bulb 3-5 times (or as recommended by your mower's manual). This action draws fuel from the tank and injects it into the carburetor, enriching the fuel-air mixture for easier starting.
• 연료 흐름을 관찰하십시오: You should see fuel moving through the fuel lines and into the carburetor as you press the bulb. The bulb should return to its original shape after each press.

Do not over-prime the engine, as this can flood the carburetor and make starting more difficult.

The primer bulb is a wear item and requires periodic inspection. There is no routine maintenance required for the primer bulb itself, beyond ensuring its proper function.

• 정기 검사: Periodically check the primer bulb for cracks, hardening, or loss of elasticity. A damaged bulb will not prime effectively.
• 연료 누출: Inspect around the primer bulb and fuel lines for any signs of fuel leakage. Address any leaks immediately.
• 대사: If the primer bulb shows signs of wear, cracking, or fails to prime the engine, replace it following the installation instructions in Section 4.

7. 문제 해결

If you experience issues related to the primer bulb, consider the following:

Engine Not Starting / Hard Starting

• Primer Bulb Not Returning: If the bulb stays depressed or returns slowly, it may be cracked or the internal spring mechanism is faulty. Replace the bulb.
• No Fuel Movement: If pressing the bulb does not visibly move fuel, check for clogged fuel lines, a faulty fuel filter, or a damaged primer bulb.
• 엔진 침수: If you smell strong gasoline or the spark plug is wet with fuel, you may have over-primed the engine. Wait a few minutes, then attempt to start without priming.
