Understanding Your PB-580t Leaf Blower Key Components

Before you learn how to start a PB-580t leaf blower, it’s important to familiarize yourself with the key components that control the starting process. Knowing what each part does will help you adjust settings correctly and troubleshoot issues if they arise.

Primer Bulb

The small, rubber primer bulb is located next to the fuel tank on the side of the blower. Its purpose is to pump fuel from the tank into the carburetor, ensuring there is enough fuel to ignite a cold engine. For cold starts, you will need to press the primer bulb 3 to 5 times until you see clear fuel flowing through the transparent fuel line attached to the bulb. Over-pumping the primer will flood the engine with excess fuel, making starting impossible until the extra fuel drains.

Throttle Trigger

The throttle trigger is located under the handle of the blower, and controls the engine speed when the blower is running. During starting, you will need to hold the trigger slightly (about 1/4 of the way down) to allow a small amount of fuel into the engine, which makes ignition easier. Never hold the throttle fully open while starting, as this will deliver too much fuel and flood the engine.

Choke Control

The choke is a lever or knob located on the side of the carburetor, and it controls the air-to-fuel ratio in the engine. For cold starts, the choke should be set to the “closed” position to restrict air flow and enrich the fuel mixture, making it easier to ignite. Once the engine fires, you will move the choke to the “half-open” position, then to fully open once the engine is warm. Most PB-580t models have three choke positions: closed (cold start), half-open (warm start), and fully open (running).

Fuel Tank

The fuel tank holds the 50:1 mixture of unleaded gas and 2-stroke oil required for the PB-580t to run. It has a sealed fuel cap to prevent leaks, and a fuel line that delivers fuel to the carburetor. Always make sure the fuel cap is tightened securely after refilling to avoid air leaks that can make starting difficult.

Spark Plug

The spark plug is located on the side of the engine, and provides the ignition spark that ignites the fuel-air mixture in the engine cylinder. A clean, properly gapped spark plug is essential for reliable starting. If the spark plug is fouled with carbon buildup or has a worn electrode, it will produce a weak or no spark, making the engine hard to start or causing it to misfire.

Air Filter

The air filter is located under the plastic air cover on the side of the blower, and prevents dust, debris, and leaves from entering the carburetor. A clogged air filter restricts air flow, making the fuel mixture too rich to ignite. Clean the air filter after every 10 hours of use to ensure proper air flow and easy starting.

Pre-Start Safety Checks You Should Never Skip

Skipping pre-start safety checks not only increases the risk of injury, but can also damage your PB-580t or cause starting failures. Take 2 minutes to complete these checks before every use.

Clear the Work Area

Remove all debris, toys, pets, and bystanders from the area you will be blowing to avoid injury from thrown objects. The PB-580t blows air at speeds up to 180 mph, which can throw small objects at dangerous velocities.

Inspect Fuel and Oil

Confirm you are using the correct 50:1 mixture of unleaded 87 octane gas and 2-stroke oil. Never use fuel that is older than 30 days, as it will degrade and cause starting issues. Check that the fuel cap is tightened securely to prevent leaks.

Check for Damage

Inspect the fuel lines for cracks or leaks, the air filter for clogs or tears, the spark plug boot for a secure connection, and the handle and throttle for cracks or loose parts. Do not use the blower if you find any damage, as it can cause starting failures or injury during operation.

Wear Proper PPE

Always wear safety glasses, hearing protection, work gloves, closed-toe shoes, and long pants when starting and operating the PB-580t. This protects you from flying debris, loud engine noise, and accidental contact with hot engine parts.

Step-by-Step Guide: How to Start a Pb-580t Leaf Blower? (Cold Start)

A cold start is required when the engine has not been run in the last 10 minutes, or when the ambient temperature is below 60°F (15°C). Follow these steps exactly for a reliable cold start every time:

1. Set the blower on a flat, stable surface with the air intake clear of debris, and ensure there are no flammable materials nearby.
2. Prime the carburetor by pressing the primer bulb 3 to 5 times, until you see clear fuel flowing through the transparent fuel line next to the bulb. This delivers fuel to the cold carburetor to enable ignition.
3. Set the choke control to the fully closed “cold start” position to enrich the fuel-air mixture.
4. Hold the throttle trigger slightly (about 1/4 of the way down) to allow a small amount of fuel into the engine. Disengage the throttle lock if your model has one.
5. Pull the starter cord slowly 2 to 3 times to get the engine to fire. You will hear a sputtering sound as the fuel ignites.
6. Once the engine fires and runs for 2 to 3 seconds, move the choke to the half-open position. Continue pulling the starter cord gently until the engine stays running on its own without your assistance.
7. Let the engine idle for 30 seconds to warm up, then release the throttle lock and move the choke to the fully open “run” position. The blower is now ready for use.

If the engine does not start after 5 to 6 pull attempts, stop pulling to avoid flooding the engine. Check for common issues like old fuel, a clogged air filter, or an incorrectly set choke before trying again.

How to Start a PB-580t Leaf Blower After It’s Been Running (Warm Start)

A warm start is used when the engine has been running in the last 10 minutes, and is still warm to the touch. Warm starts are faster and require fewer steps than cold starts:

1. Set the blower on a flat, stable surface with the air intake clear of debris.
2. Only prime the carburetor 1 to 2 times if the engine has been off for more than 5 minutes. If the engine is still warm, you can skip priming entirely.
3. Set the choke to the half-open position, or fully open if the engine is still very warm.
4. Hold the throttle trigger slightly, then pull the starter cord once or twice. The engine should start immediately.
5. Let the engine idle for 10 to 15 seconds, then release the throttle and set the choke to fully open.

If the engine does not start on the first pull, it may have cooled too much to run on a warm start. Switch to the cold start procedure outlined above to get it running.

Troubleshooting Common Starting Issues

Even with the correct starting procedure, you may occasionally run into starting issues with your PB-580t. Here are the most common problems and their fixes:

Won’t Start After Priming and Multiple Pulls

This is almost always caused by one of four issues: old or incorrectly mixed fuel, a clogged air filter, a faulty spark plug, or an incorrectly set choke. First, confirm you are using fresh 50:1 2-stroke mix. Next, remove and clean the air filter, check the spark plug for fouling or damage, and confirm the choke is fully closed for a cold start. If all of these are correct, the carburetor may be clogged and need cleaning.

Engine Fires But Dies Immediately

This is usually caused by the choke being left in the closed position, the throttle not being held slightly during starting, or a clogged fuel filter. First, move the choke to the half-open position as soon as the engine fires. Hold the throttle lightly while starting, and check the fuel filter for clogs that may be blocking fuel delivery to the carburetor.

No Spark at the Spark Plug

A lack of spark prevents the engine from igniting fuel, so it will not start. To test for spark, remove the spark plug, hold the metal base of the plug against the engine block (wear gloves to avoid shock), and pull the starter cord. You should see a bright blue spark between the electrode and the ground. If there is no spark, first replace the spark plug with a new, properly gapped plug. If there is still no spark, the ignition coil may be faulty and need replacement.

Flooded Engine (Too Much Fuel)

A flooded engine occurs when too much fuel enters the cylinder, making it impossible to ignite. This is usually caused by over-priming the carburetor, holding the throttle fully open while starting, or pulling the starter cord too many times with the choke closed. To fix a flooded engine, set the choke to fully open, hold the throttle fully open, and pull the starter cord 5 to 6 times to push excess fuel out of the cylinder. Wait 5 minutes for the remaining fuel to evaporate, then try starting again, priming only 2 times this time to avoid re-flooding.

PB-580t Fuel and Maintenance Tips for Reliable Starting

Most starting issues with the PB-580t are preventable with proper fuel handling and regular maintenance. Follow these tips to keep your blower starting reliably:

Use the Correct Fuel Mix

The PB-580t requires a 50:1 ratio of unleaded 87 octane gas to 2-stroke oil. Never use straight gas, as it will destroy the engine’s internal components by removing lubrication. Never use 4-stroke oil, as it is too thick for 2-stroke engines and will cause carbon buildup. For occasional users, pre-mixed 2-stroke fuel with added stabilizer is the best option, as it stays fresh for up to 2 years and eliminates the need to mix fuel yourself.

Store Fuel Properly

If you mix your own fuel, it will only stay fresh for 30 days at room temperature, or 90 days if stored in a cool, dry place with a fuel stabilizer added. Never store fuel in direct sunlight or near heat sources, as this can cause it to degrade faster. If you will not use the blower for more than 2 months, drain all fuel from the tank and carburetor to prevent it from gelling and clogging the fuel system.

Follow a Regular Maintenance Schedule

Basic maintenance every 10 hours of use will prevent 90% of starting issues. After every 10 hours, clean the air filter, check the spark plug for fouling, and inspect fuel lines for cracks. After every 50 hours of use, replace the spark plug, clean the carburetor jets, and replace the fuel filter. This simple schedule will keep your PB-580t running smoothly for years.

Comparison: PB-580t Starting Process vs. Other Common Leaf Blowers

The PB-580t’s starting process is unique to 2-stroke gas-powered blowers, and differs significantly from 4-stroke and electric models. The table below compares the starting process of the PB-580t to three other common leaf blower types to help you understand what to expect.

As the table shows, the PB-580t’s starting process is nearly identical to most standard 2-stroke handheld blowers, but more involved than 4-stroke or electric models. The extra steps required for starting are a fair tradeoff for the blower’s high power output, cordless portability, and lower emissions compared to 4-stroke gas models.

Top Tips for Easy PB-580t Starting Every Time

Follow these pro tips to eliminate starting frustration and keep your PB-580t running reliably:

• Use only fresh 50:1 2-stroke fuel: Old fuel is the #1 cause of starting issues for the PB-580t. Discard mixed fuel after 30 days, or use pre-mixed fuel with stabilizer for occasional use.
• Prime the carburetor correctly: Use 3 to 5 pumps for cold starts, 1 to 2 pumps for warm starts. Over-priming will flood the engine, while under-priming will not deliver enough fuel to ignite.
• Adjust the choke properly: Use the closed choke position only for cold starts. Move to half-open once the engine fires, and fully open once the engine is warm. Leaving the choke closed after starting will cause the engine to stall and run poorly.
• Hold the throttle slightly during starting: This delivers a small amount of fuel to the engine for easier ignition. Never hold the throttle fully open while starting, as this will flood the engine.
• Clean the air filter regularly: A clogged air filter restricts air flow and makes the fuel mixture too rich to start. Clean it with soap and water after every 10 hours of use, and replace it if it is torn or heavily soiled.
• Store the blower properly in the off-season: Drain all fuel from the tank and carburetor if you will not use the blower for more than 2 months. Store it in a cool, dry place away from direct sunlight to prevent fuel gel and carburetor clogs.

Common Mistakes to Avoid When Starting Your PB-580t

Avoid these common mistakes to prevent starting failures and damage to your blower:

• Using old or incorrect fuel: Straight gas, 4-stroke oil, or fuel mixed at the wrong ratio will damage the engine and prevent starting. Always use 50:1 2-stroke mix, and drain the tank immediately if you accidentally used the wrong fuel.
• Over-priming the carburetor: Pumping the primer bulb more than 5 times will flood the engine with excess fuel. If you over-prime, clear the excess fuel by setting the choke to fully open, holding the throttle open, and pulling the starter cord 5 to 6 times before trying to start again.
• Leaving the choke closed after the engine starts: This causes the engine to run too rich, stall immediately, and waste fuel. Move the choke to half-open as soon as the engine fires, then fully open once it is warmed up.
• Yanking the starter cord too hard: This can damage the starter mechanism over time. Pull the cord smoothly and steadily, rather than using full force.
• Starting the blower in an enclosed space: The engine exhaust contains carbon monoxide, an odorless, deadly gas. Always start and run the PB-580t in a well-ventilated outdoor area to avoid carbon monoxide poisoning.

Frequently Asked Questions

How long does it take to cold start a PB-580t leaf blower?

A well-maintained PB-580t with fresh fuel should start in 3 to 5 pulls of the starter cord when following the correct cold start procedure. If it takes more than 10 pulls to start, check for common issues like old fuel, a clogged air filter, or an incorrectly set choke.

What happens if I use the wrong fuel in my PB-580t?

Using straight unleaded gas without 2-stroke oil will cause the engine to seize within minutes of running, as there is no lubrication for the internal moving parts. Using 4-stroke oil or fuel mixed at the wrong ratio will cause carbon buildup, poor performance, and starting issues. If you accidentally used the wrong fuel, drain the tank immediately and refill with the correct 50:1 mix before attempting to start the engine.

How do I fix a flooded PB-580t engine?

To clear a flooded engine, set the choke to the fully open “run” position, hold the throttle trigger fully open, and pull the starter cord 5 to 6 times to push excess fuel out of the cylinder. Wait 5 minutes for remaining fuel to evaporate, then try starting again, priming the carburetor only 2 times to avoid re-flooding.

How often should I replace the spark plug on my PB-580t?

The manufacturer recommends replacing the spark plug every 50 hours of use, or once per year for infrequent users. A worn or fouled spark plug will produce a weak or no spark, leading to hard starting or engine misfires. You can clean a fouled spark plug with a wire brush and re-gap it, but replacement is inexpensive and ensures reliable performance.

Can I start my PB-580t if it’s been sitting for 6 months?

Yes, but only if it was stored properly. If you left fuel in the tank and carburetor, drain all old fuel first, as it will have gelled and clogged the fuel system. Add fresh 50:1 mixed fuel, prime the carburetor 5 times, set the choke to closed, and follow the cold start procedure. If it still won’t start, you may need to clean the carburetor or replace the spark plug.

Do I need to use the choke every time I start the PB-580t?

Only for cold starts, when the engine is at room temperature or colder. For warm starts (engine was running in the last 10 minutes), set the choke to half-open, or fully open if the engine is still warm. Using the choke on a warm engine will flood it with too much fuel, making starting difficult.

Conclusion

Learning how to start a PB-580t leaf blower is simple once you understand the key components, follow pre-start safety checks, and use the correct procedure for cold or warm starts. The most common causes of starting failures are old fuel, incorrect choke settings, and lack of regular maintenance, all of which are easy to avoid with the tips outlined in this guide. If you do run into issues, the troubleshooting steps provided will help you fix the problem quickly without needing professional repair. With proper care, your PB-580t will start reliably every time, making yard work and fall leaf cleanup fast and frustration-free.
