Understanding Your Stihl Leaf Blower Types

Stihl produces three main categories of leaf blowers, each with a distinct start process, so the first step to answering How to Start Leaf Blower Stihl? is identifying which type of model you own. The most common types include:

• Gas-powered leaf blowers: These are the most powerful Stihl models, ideal for large yards, commercial use, and clearing heavy, wet debris. Popular models include the BG 50, BG 86, and SH 56. They run on a 50:1 pre-mixed fuel blend, and require a manual start process involving priming, choke adjustment, and pulling the starter cord.
• Corded electric leaf blowers: These lightweight, low-emission models are perfect for small to medium yards with easy access to electrical outlets. Common models include the SHE 71 and SHE 81. They start instantly with the flip of a switch, no fuel or priming required.
• Battery-powered leaf blowers: Part of Stihl’s AK and AP battery systems, these cordless models offer the convenience of gas power without the fumes or noise. Popular models include the BGA 45, BGA 56, and BGA 86. They start with the push of a trigger once the battery is seated, making them ideal for noise-sensitive areas and residential use.

Most start issues stem from using the wrong procedure for your blower type, so confirming your model before you begin will save you time and frustration.

Pre-Start Safety Checks

Before you attempt to start your Stihl leaf blower, completing a few quick safety checks will prevent injury and damage to your equipment. These steps apply to all blower types:

1. Read your owner’s manual: While this guide covers general Stihl start procedures, your specific model may have unique requirements or safety features outlined in the manual. Keep the manual in a convenient place for reference.
2. Wear proper personal protective equipment (PPE): Always wear safety goggles to protect your eyes from flying debris, hearing protection to guard against loud engine noise, and non-slip gloves to improve your grip on the blower. For gas models, wear a mask if you’re working in dusty conditions.
3. Clear the work area: Remove any rocks, sticks, toys, or other obstacles from the area where you’ll be starting the blower. This prevents debris from being thrown by the blower when it starts, and gives you space to move safely if the blower kicks back.
4. Check for fuel leaks (gas models only): Inspect the fuel tank, fuel lines, and carburetor for any signs of leaks or cracks before starting. If you smell gas or see fuel dripping, do not start the blower – address the leak first to avoid fire risk.
5. Place the blower on a flat, stable surface: Never start a gas-powered blower while holding it, as it can kick back unexpectedly. Set it on level ground, and stand behind it with a firm grip on the handle before pulling the starter cord.
6. Disconnect the spark plug (for gas models only, if performing maintenance): If you’ve recently cleaned the air filter, adjusted the carburetor, or done any work on the engine, disconnect the spark plug wire before attempting to start the blower to avoid accidental ignition.

For gas models, never start the blower indoors, in a garage, or in any enclosed space, as carbon monoxide fumes from the engine are odorless and deadly. Always start and run gas blowers in a well-ventilated outdoor area.

Step-by-Step Cold Start for Gas Stihl Leaf Blowers

A cold start refers to starting a gas-powered Stihl leaf blower that has not been run in the last 30 minutes, or that has been stored for an extended period. This is the most common start scenario for new users, and following these steps exactly will help you avoid flooding the engine or damaging the carburetor:

1. Prime the carburetor (if your model has a primer bulb): Most modern Stihl gas leaf blowers have a small rubber primer bulb located near the carburetor. Press the bulb 3 to 5 times, holding it down for 1 second each time, until you see fuel flowing through the clear fuel line connected to the bulb. If your model does not have a primer bulb (older models like the BG 45), skip this step and pull the starter cord 2 to 3 times with the choke closed to draw fuel into the carburetor.
2. Set the choke to the closed (cold start) position: The choke restricts airflow to the carburetor to create a richer fuel mixture for cold starts. On most Stihl models, the choke lever is located near the throttle handle, and the closed position is marked with a rabbit icon or labeled “Cold Start.” Move the lever to this position fully.
3. Set the throttle to the start position: Move the throttle lever to the “Start” position, which is usually marked with a turtle icon or labeled “Start.” This opens the throttle slightly to give the engine enough air to fire when you pull the starter cord. Do not set the throttle to full open for starting, as this can cause flooding.
4. Pull the starter cord: Stand behind the blower with one hand on the handle and the other on the starter cord grip. Pull the cord slowly at first to feel for resistance, then pull it firmly and quickly in one smooth motion. Repeat this 3 to 4 times. If your model has Stihl’s Easy2Start system, you will only need to pull the cord 1 to 2 times, as the built-in damper reduces the amount of force needed.
5. Adjust the choke once the engine sputters: As soon as you hear the engine sputter or catch, move the choke lever to the half-open position. This adjusts the fuel mixture to a leaner setting as the engine warms up. Let the blower run for 30 seconds at this setting to warm up.
6. Open the choke fully and set to idle: After 30 seconds of running, move the choke lever to the fully open position (marked with a turtle icon or “Run”). Adjust the throttle to the idle position, and your blower is ready to use.

If the blower does not start after 4 pulls of the starter cord, wait 10 seconds before pulling again. Pulling the cord too many times in a row will flood the engine with excess fuel, making it harder to start.

Step-by-Step Warm Start for Gas Stihl Leaf Blowers

A warm start is used when your Stihl gas leaf blower has been run within the last 30 minutes, and the engine is still warm from recent use. This process is much faster than a cold start, and takes just a few seconds:

1. Skip priming the carburetor: Since the engine is already warm, there is enough fuel in the carburetor to start the blower, so you do not need to press the primer bulb.
2. Set the choke to half-open (or fully open if the engine is fully warm): If the blower was turned off less than 10 minutes ago, set the choke to the half-open position. If it was run within the last 5 minutes, you can leave the choke fully open.
3. Set the throttle to the start position: Move the throttle lever to the “Start” position, just like you would for a cold start.
4. Pull the starter cord once or twice: Pull the starter cord firmly one time. In most cases, the blower will start immediately. If it doesn’t start on the first pull, pull it one more time, then wait a few seconds before pulling again to avoid flooding.
5. Adjust to idle: Once the blower is running, move the throttle to the idle position, and it’s ready to use.

If your blower has been sitting for 10 to 30 minutes, treat it as a cold start, as the engine may have cooled down enough to require a richer fuel mixture. (See Also:What Oil To Mix For Leaf Blower)

How to Start Electric Stihl Leaf Blowers

Corded electric Stihl leaf blowers are the easiest to start, with no priming, choke adjustment, or pulling required. Follow these steps to start your model:

1. Plug the blower into a grounded 120V outlet: Use a heavy-duty, 3-prong extension cord if your work area is more than 50 feet from an outlet. Stihl recommends a 12-gauge extension cord for runs over 50 feet to avoid voltage drop that can damage the motor. Inspect the cord for any cuts or fraying before plugging it in, and never use a damaged cord.
2. Confirm the power switch is in the off position: Most Stihl corded blowers have a rocker switch on the handle. Make sure it is flipped to “Off” before plugging in the blower to avoid accidental start-up.
3. Stand in a stable, balanced position: Hold the blower handle firmly with both hands, and make sure the blower tube is pointed away from your body and any bystanders.
4. Press the trigger lockout and squeeze the trigger: Most Stihl corded blowers have a trigger lockout button that you must press before you can squeeze the main trigger. Press the lockout with your thumb, then squeeze the trigger fully to start the blower. For models with variable speed control, start at the lowest speed setting first, then adjust to your desired power as needed.

Never use a corded Stihl leaf blower in wet conditions, as water can cause electric shock. Always unplug the blower when not in use, and wrap the cord around the handle for storage to avoid damage.

How to Start Battery-Powered Stihl Leaf Blowers

Stihl’s battery-powered leaf blowers are just as easy to start as corded models, with the added convenience of cordless operation. Follow these steps to start your battery model:

1. Confirm the battery is fully charged: Check the LED charge indicator on your Stihl AK or AP series battery. A solid green light means the battery is fully charged, a flashing green light means it is partially charged, and a red light means it needs to be recharged. For optimal performance, always start with a fully charged battery, especially for heavy-duty use.
2. Seat the battery in the blower: Align the battery with the slot on the lower part of the blower handle, then push it in firmly until you hear a distinct click. This click indicates the battery is locked in place and making proper contact with the blower’s power terminals. If the battery is not seated correctly, the blower will not start.
3. Engage the safety lock: Most Stihl battery blowers have a safety lock on the handle that prevents accidental start-up. Make sure the lock is disengaged before you try to start the blower.
4. Hold the blower firmly and squeeze the trigger: Stand in a stable position, hold the handle with both hands, and make sure the blower tube is pointed away from people and pets. Squeeze the trigger fully to start the blower. Many models have a boost button that you can press for extra power when clearing heavy debris.

To check the remaining battery life while using the blower, press the battery indicator button on the blower handle to see how much charge is left. When the battery is low, the blower will slow down automatically to alert you to recharge it.

Troubleshooting Common Start Issues

Even if you follow the correct start procedure, you may run into occasional issues with your Stihl leaf blower. Here are the most common problems and how to fix them:

Gas-Powered Blower Won’t Start

• Stale fuel: Gas begins to degrade after 30 days, especially if it contains ethanol. If your blower has been sitting with old gas in the tank, drain the fuel and refill with fresh Stihl pre-mixed fuel or fresh 89+ octane unleaded gas.
• Clogged air filter: A dirty air filter restricts airflow to the engine, preventing it from starting. Remove the air filter cover, take out the foam or paper filter, and clean it with warm soapy water (foam) or compressed air (paper). Replace the filter if it is torn or heavily soiled.
• Worn or dirty spark plug: Remove the spark plug with a spark plug wrench, and inspect it for carbon buildup or wear. Clean the plug with a wire brush, and check the gap with a feeler gauge (it should be 0.02 inches for most Stihl models). Replace the spark plug if it is damaged or the gap is incorrect.
• Flooded engine: If you smell raw gas from the exhaust and the blower won’t start, the engine is flooded. Set the choke to fully open, pull the starter cord 3 to 4 times to clear excess fuel, then wait 10 to 15 minutes before trying to start again. Do not prime the carburetor for the next start attempt.

Electric Blower Won’t Start

• Check that the outlet is working by plugging in another device. If the outlet is not working, reset your home’s circuit breaker or try a different outlet.
• Inspect the power cord for cuts, fraying, or exposed wires. If the cord is damaged, do not use the blower until it is repaired or replaced.
• Some Stihl electric blowers have a reset button on the motor housing. If the blower shuts off unexpectedly, press the reset button and try starting again.

Battery Blower Won’t Start

• Check the battery charge level. If the battery is dead, recharge it fully before trying again.
• Remove the battery and re-seat it firmly in the blower, making sure it clicks into place.
• Clean the metal contacts on the battery and blower with a dry cloth to remove dirt or corrosion that may be preventing power transfer.

Maintenance Tips to Keep Your Stihl Starting Easily

Regular maintenance is the best way to avoid start issues and extend the life of your Stihl leaf blower. Follow these tips to keep your blower running smoothly:

1. Use the right fuel for gas models: Always use fresh 89+ octane unleaded gas with no more than 10% ethanol, or Stihl’s pre-mixed 50:1 fuel for the easiest starts and best performance. Add a fuel stabilizer if you won’t use the blower for more than 2 weeks, to prevent fuel from degrading.
2. Clean the air filter regularly: Clean the air filter after every 25 hours of use, or more often if you’re working in dusty or dirty conditions. A clogged air filter is one of the most common causes of hard starting and poor performance.
3. Change the spark plug annually: Replace the spark plug every 100 hours of use, or once a year, to ensure consistent ignition. Check the spark plug gap every 50 hours to make sure it is set to the manufacturer’s specifications.
4. Store your blower properly: For gas models, drain the fuel tank completely if you won’t use the blower for more than a month, to prevent fuel from clogging the carburetor. Store the blower in a cool, dry place, covered to protect it from dust and moisture. For battery models, store the battery at 40-50% charge in a cool, dry place, away from extreme heat or cold.
5. Clean the blower after each use: Wipe down the exterior of the blower, and clear any debris from the intake, exhaust, and blower tube to prevent clogs that can affect starting and performance.

Best Practices for Long-Term Performance

Following these best practices will ensure your Stihl leaf blower starts easily every time, and lasts for years of reliable use:

• Follow your model’s specific start procedure: While this guide covers general Stihl start steps, always refer to your owner’s manual for model-specific instructions. Some newer Stihl models have automatic chokes or Easy2Start systems that simplify the process, while older models may require manual priming.
• Avoid over-priming gas models: Pressing the primer bulb more than 5 times will flood the engine with fuel, making it impossible to start until the excess fuel clears. If you’re unsure if the carburetor is primed, press the bulb 3 times, then wait 10 seconds before pressing again if needed.
• Use Stihl-approved fuel and parts: Using non-approved fuel, aftermarket spark plugs, or air filters can damage your blower and cause starting issues. Stihl parts and fuel are formulated specifically for their equipment to ensure optimal performance.
• Don’t store gas in the blower long-term: Ethanol in modern gasoline absorbs water over time, which can cause corrosion in the carburetor and fuel lines. If you won’t use your gas blower for more than 2 weeks, drain the fuel tank completely, then run the engine until it stalls to clear fuel from the carburetor.
• Keep the starter cord in good condition: Inspect the starter cord regularly for fraying or wear. If the cord is damaged, replace it immediately to avoid it snapping while you’re pulling it, which can cause injury or damage to the starter mechanism.

Frequently Asked Questions

Why won’t my Stihl leaf blower start even after following the steps?

This is usually caused by stale fuel, a clogged air filter, or a worn spark plug. First, check that you’re using fresh gas (less than 30 days old), then clean or replace the air filter, and inspect the spark plug for wear or carbon buildup. If those are all in good shape, the carburetor may need to be cleaned or adjusted by a Stihl service center.

Can I use regular unleaded gas in my Stihl gas leaf blower?

Stihl recommends using 89 octane or higher unleaded gas with no more than 10% ethanol. For the best performance and easiest starts, use Stihl’s pre-mixed 50:1 fuel, which is ethanol-free and formulated specifically for Stihl outdoor power equipment. Regular gas with high ethanol content can cause carburetor clogs, corrosion, and starting issues over time.

How do I know if my Stihl leaf blower is flooded?

If you’ve pulled the starter cord multiple times and the engine won’t start, and you smell raw gas coming from the exhaust, the engine is likely flooded. To fix this, set the choke to the fully open position, pull the starter cord 3 to 4 times to clear the excess fuel, then wait 10 to 15 minutes before trying to start it again. Avoid priming the carburetor again for the next start attempt to prevent re-flooding.

Do Stihl battery leaf blowers lose charge when stored?

Yes, all lithium-ion batteries lose a small amount of charge over time when stored. For the best performance and longest battery lifespan, store your Stihl battery at 40-50% charge in a cool, dry place (away from extreme heat or cold, which can damage the cells). If you won’t use the blower for more than 3 months, charge the battery to 50% every 3 months to preserve its capacity.

Is it normal for a new Stihl leaf blower to be hard to start?

New gas-powered Stihl leaf blowers may be slightly harder to start for the first few uses as the engine breaks in. Follow the cold start procedure exactly, and avoid over-priming the carburetor. If the blower still won’t start after 5 to 6 attempts, contact Stihl customer support, as there may be a manufacturing defect. Electric and battery models should start instantly out of the box, so if they don’t, check the power source or battery connection first. (See Also:How To Store Leaf Blower For Winter)

Can I start my Stihl leaf blower in cold weather?

Yes, but gas-powered models may require a slightly richer fuel mixture in temperatures below 40°F (4°C). For cold weather starts, press the primer bulb 4 to 5 times instead of 3, keep the choke closed for an extra 10 to 15 seconds after the engine starts to let it warm up, and use winter-grade oil in the fuel mix if you’re operating in temperatures below 0°F (-18°C). Electric and battery models will start in cold weather, but battery life may be reduced in very low temperatures, so keep the battery warm in your pocket before use if possible.
