How to Connect the Bulb Primer on a Husqvarna 125BV Chainsaw

The Husqvarna 125BV is a reliable chainsaw, but starting it can be tricky if you're not familiar with the process. A key component in easy starting is the bulb primer. This guide will walk you through how to properly connect and use the bulb primer on your Husqvarna 125BV. Understanding this process will significantly improve your chainsaw starting experience.

Locating the Bulb Primer

Before you begin connecting anything, you need to locate the bulb primer itself. It's a small, usually pear-shaped bulb, often found near the carburetor on your Husqvarna 125BV. It's typically made of a flexible, transparent or translucent material. Take a moment to carefully examine your chainsaw's carburetor area to identify it. If you are unsure, consult your owner's manual for a visual reference.

Connecting the Bulb Primer (If Disconnected)

The bulb primer should be connected directly to the carburetor via a small fuel line. If it's disconnected, you'll need to reconnect it. This typically involves:

1. Identifying the Fuel Line: Find the small fuel line that connects to the carburetor. It's a thin tube, usually made of rubber or plastic.

2. Connecting the Line to the Primer: Carefully push the fuel line onto the nipple on the bulb primer. Ensure a secure connection. A slight resistance indicates a proper fit. Do not force it. If it doesn't fit easily, double-check that you have the correct line and that you're inserting it correctly.

3. Check for Leaks: After connecting, gently squeeze the bulb primer several times. Inspect the connection for any leaks. If you see fuel leaking, the connection isn't secure, and you'll need to repeat steps 1 and 2, ensuring a tight fit.

Using the Bulb Primer to Start Your Husqvarna 125BV

Once you've confirmed the bulb primer is properly connected, starting your chainsaw becomes significantly easier. Here’s how to use it effectively:

1. Ensure Sufficient Fuel: Make sure your chainsaw has enough fuel in the tank.

2. Prime the Carburetor: Before attempting to start the chainsaw, squeeze the bulb primer several times until it becomes firm and no more air bubbles are visible within the bulb. This pumps fuel into the carburetor, preparing the engine for starting. Aim for a consistent, firm feel in the bulb; avoid over-squeezing.

3. Start the Chainsaw: Follow the starting procedure outlined in your Husqvarna 125BV owner's manual. This usually involves activating the choke (if necessary), pulling the starter cord, and gradually transitioning to the run position.

Troubleshooting

If your chainsaw still struggles to start even after using the bulb primer, consider the following:

• Fuel Quality: Ensure you're using fresh, high-quality fuel mixed at the correct ratio as specified in your owner's manual. Old or improperly mixed fuel can hinder starting.
• Air Filter: A clogged air filter can restrict airflow to the engine, making starting difficult. Clean or replace your air filter as needed.
• Spark Plug: A faulty spark plug can prevent the engine from igniting. Inspect and, if necessary, replace the spark plug.

Remember to always consult your owner's manual for detailed instructions and safety precautions specific to your Husqvarna 125BV chainsaw.

By following these steps, you’ll be able to confidently connect and utilize the bulb primer on your Husqvarna 125BV, leading to easier and more reliable starting every time. This improved starting capability will enhance your overall chainsaw operation and productivity.
