The Echo PB-580T is a powerful and reliable leaf blower, a staple in many landscaping businesses and homeowner garages alike. But even the most dependable tools require maintenance and occasional repair. As someone who’s spent years working with logging tools and maintaining equipment, I’ve encountered my fair share of leaf blower issues. I’m going to share five common problems and the fixes that seasoned professionals use to keep their Echo PB-580T blowers running smoothly.
Understanding Noise Reduction and Its Importance
Before diving into repairs, it’s important to address noise reduction. High noise levels are not only annoying but also pose a health risk. Prolonged exposure to loud machinery like leaf blowers can lead to hearing loss. The Echo PB-580T, while powerful, can generate significant noise. Understanding how to mitigate this noise is crucial for operator safety and maintaining good relations with neighbors.
Noise reduction starts with maintaining the blower properly. A well-tuned engine runs smoother and quieter. Regularly inspect and replace worn parts, such as the muffler, which is specifically designed to dampen engine noise. Using hearing protection, like earmuffs or earplugs, is also essential, especially during extended use. Lastly, being mindful of operating hours and avoiding early morning or late evening use can minimize disturbance to others.
Let’s get started with those repairs!
1. The Blower Won’t Start: Fuel and Spark
The most common complaint I hear is, “My Echo PB-580T just won’t start!” Nine times out of ten, the problem lies within the fuel system or the ignition system.
Fuel System Inspection and Cleaning
Fuel issues are often the culprit. Over time, fuel can degrade and leave behind varnish or deposits that clog the carburetor, fuel lines, and fuel filter.
- Step 1: Check the Fuel Mix. Echo products require a specific fuel-to-oil ratio, typically 50:1. Using the wrong ratio, or old fuel, can wreak havoc. I always use a high-quality two-cycle engine oil and fresh gasoline. I recommend non-ethanol fuel whenever possible, as ethanol can attract moisture and cause corrosion.
- Step 2: Inspect the Fuel Filter. The fuel filter is located inside the fuel tank, attached to the fuel line. Remove the fuel line from the carburetor and pull out the fuel filter. If it’s dirty or clogged, replace it. I keep a few spares on hand. A clogged fuel filter restricts fuel flow, preventing the engine from starting.
- Step 3: Examine the Fuel Lines. Look for cracks, kinks, or leaks in the fuel lines. Replace any damaged lines immediately. A leak can cause a loss of fuel pressure, making starting difficult.
-
Step 4: Clean the Carburetor. The carburetor mixes air and fuel to create a combustible mixture. A clogged carburetor is a frequent cause of starting problems. If the fuel filter and lines are clear, the carburetor likely needs cleaning.
- Disassembly: Carefully disassemble the carburetor, noting the location of each component. Take pictures as you go to help with reassembly.
- Cleaning: Use carburetor cleaner to thoroughly clean all parts, paying special attention to the jets and passages. I use a set of carburetor cleaning picks to ensure all passages are clear.
- Reassembly: Reassemble the carburetor, ensuring all parts are correctly positioned.
- Step 5: Check the Primer Bulb. The primer bulb helps to prime the engine with fuel. If it’s cracked or damaged, it won’t work properly. Replace it if necessary.
Estimated Time: 30-60 minutes Tools Required: Screwdrivers, pliers, carburetor cleaner, carburetor cleaning picks, replacement fuel filter, replacement fuel lines (if needed), replacement primer bulb (if needed). Cost: Fuel filter ($5-10), fuel lines ($5-15), carburetor cleaner ($5-10), primer bulb ($5-10).
Ignition System Inspection
If the fuel system is functioning correctly, the next step is to check the ignition system. The ignition system generates the spark that ignites the fuel-air mixture in the engine.
- Step 1: Check the Spark Plug. Remove the spark plug and inspect it. Look for cracks, carbon buildup, or damage to the electrode. Clean the spark plug with a wire brush or replace it if necessary. I recommend using the spark plug specified in the Echo PB-580T owner’s manual.
- Step 2: Test for Spark. Reconnect the spark plug to the spark plug wire and ground the spark plug against the engine block. Pull the starter rope. You should see a strong, blue spark. If there’s no spark, or the spark is weak, the ignition coil may be faulty.
- Step 3: Check the Ignition Coil. The ignition coil generates the high voltage needed to create a spark. If the ignition coil is faulty, it will need to be replaced. To test the ignition coil, use a multimeter to check the resistance between the terminals. Refer to the Echo PB-580T service manual for the correct resistance values.
- Step 4: Check the Spark Plug Wire. Inspect the spark plug wire for damage or corrosion. Replace it if necessary.
Estimated Time: 15-30 minutes Tools Required: Spark plug wrench, spark plug cleaner or wire brush, multimeter, replacement spark plug (if needed), replacement ignition coil (if needed), replacement spark plug wire (if needed). Cost: Spark plug ($5-10), ignition coil ($20-40), spark plug wire ($5-10).
Real-World Example: I once had an Echo PB-580T that refused to start. I went through all the fuel system checks, replaced the fuel filter, and cleaned the carburetor. Still nothing. Finally, I checked the spark plug and found it was cracked. A new spark plug was all it needed!
Takeaway: Don’t overlook the simple things. Always start with the basics – fuel and spark – when troubleshooting a starting problem.
2. Loss of Power or Poor Performance: Airflow and Exhaust
If your Echo PB-580T starts but lacks power or runs poorly, the problem often involves restricted airflow or exhaust. A clogged air filter or a blocked exhaust port can significantly reduce engine performance.
Air Filter Inspection and Cleaning
The air filter prevents dirt and debris from entering the engine. A dirty air filter restricts airflow, causing the engine to run lean and lose power.
- Step 1: Remove the Air Filter Cover. Locate the air filter cover and remove it.
- Step 2: Inspect the Air Filter. Examine the air filter for dirt and debris. If it’s dirty, clean it or replace it.
- Step 3: Clean the Air Filter. If the air filter is a foam type, wash it with warm soapy water, rinse it thoroughly, and allow it to dry completely. If it’s a paper type, gently tap it to remove loose dirt. Avoid using compressed air, as it can damage the filter.
- Step 4: Reinstall the Air Filter. Reinstall the air filter and the air filter cover.
Estimated Time: 5-10 minutes Tools Required: Screwdriver (depending on the air filter cover), warm soapy water (for foam filters). Cost: Replacement air filter ($5-10).
Exhaust Port Inspection and Cleaning
The exhaust port allows exhaust gases to escape the engine. Over time, carbon deposits can build up in the exhaust port, restricting exhaust flow and reducing engine power.
- Step 1: Remove the Muffler. Carefully remove the muffler from the engine. Be cautious, as the muffler can be hot if the engine has been running recently.
- Step 2: Inspect the Exhaust Port. Examine the exhaust port for carbon buildup.
- Step 3: Clean the Exhaust Port. Use a scraper or a wire brush to remove carbon deposits from the exhaust port. Be careful not to damage the threads of the exhaust port.
- Step 4: Clean the Spark Arrestor Screen. Many Echo PB-580T blowers have a spark arrestor screen in the muffler. Clean the spark arrestor screen with a wire brush to remove carbon deposits. A clogged spark arrestor screen can also restrict exhaust flow.
- Step 5: Reinstall the Muffler. Reinstall the muffler, ensuring it’s properly tightened.
Estimated Time: 30-45 minutes Tools Required: Screwdrivers, wrenches, scraper, wire brush. Cost: None (unless the muffler gasket needs replacement, which is typically $2-5).
Original Insight: I’ve found that using a small propane torch to burn off the carbon deposits in the exhaust port can be very effective, especially for stubborn buildup. However, use extreme caution and ensure you’re working in a well-ventilated area away from flammable materials.
Takeaway: Regular air filter cleaning and occasional exhaust port cleaning are essential for maintaining peak engine performance.

Takeaway: Don’t ignore excessive vibration. It can be a sign of a serious problem that needs to be addressed promptly.
4. Difficulty Starting When Warm: Vapor Lock and Heat Soak
Sometimes, an Echo PB-580T will start fine when cold but become difficult to start after it’s been running for a while. This is often due to vapor lock or heat soak.
Understanding Vapor Lock and Heat Soak
- Vapor Lock: Vapor lock occurs when the fuel in the fuel line or carburetor vaporizes due to excessive heat. The fuel vapor prevents the engine from getting a consistent flow of liquid fuel, making it difficult to start.
- Heat Soak: Heat soak occurs when the engine components absorb excessive heat, making it difficult to start. This can be exacerbated by poor ventilation or a lean fuel mixture.
Addressing Vapor Lock and Heat Soak
- Step 1: Allow the Blower to Cool Down. The simplest solution is often to allow the blower to cool down for 15-30 minutes before attempting to restart it.
- Step 2: Check the Fuel Cap. Ensure the fuel cap is properly vented. A clogged fuel cap vent can create a vacuum in the fuel tank, making it difficult for fuel to flow to the carburetor.
