Understanding Your Stihl Leaf Blower

Stihl produces three main types of leaf blowers, each designed for different use cases and requiring unique starting steps. Identifying your model type is the first step to learning how to turn on Stihl leaf blower? correctly, as using the wrong procedure can damage the engine or prevent starting entirely.

Gas-Powered Stihl Models

Gas-powered Stihl blowers, such as the BG 86 and BR 700 series, are the most powerful option, ideal for large properties, commercial use, or areas without access to electricity. They run on a 2-stroke engine that requires a mixture of gasoline and 2-stroke oil to operate. These models are the most common choice for heavy-duty yard work, but they require more maintenance and a more involved starting process than battery or electric models.

Battery-Powered Stihl Models

Battery-powered Stihl blowers, part of the AK or AP battery system (such as the BGA 56), are cordless, quiet, and zero-emission. They are perfect for small to medium residential yards, noise-sensitive neighborhoods, and users who want to avoid mixing fuel. Runtime varies by battery capacity, but most models run for 20–45 minutes per full charge.

Electric Corded Stihl Models

Corded electric Stihl blowers, like the SHE 81, are lightweight, low-maintenance, and produce zero emissions. They are best suited for small yards with easy access to outdoor outlets, as their range is limited by the length of the power cord. They have the simplest starting process of all three types, with no fuel or battery required.

Pre-Start Safety Checks

Before attempting to start your Stihl leaf blower, completing a few quick safety checks will reduce the risk of injury and prevent damage to the equipment. These steps only take a minute but will save you time and hassle later.

Personal Protective Equipment

Leaf blowers produce high-velocity debris and loud noise, so wearing proper PPE is non-negotiable. Always put on the following before starting your blower:

• Safety glasses or goggles: Protect your eyes from flying leaves, twigs, rocks, and other debris.
• Hearing protection: Most leaf blowers produce 90–110 dB of noise, which can cause permanent hearing damage with prolonged exposure. Use earplugs or over-ear hearing protection.
• Work gloves: Reduce vibration fatigue and protect your hands from sharp debris or hot engine parts (for gas models).
• Closed-toe shoes: Protect your feet from falling objects or accidental contact with the blower nozzle.
• Long pants: Shield your legs from debris and scratches from low-hanging branches.

Workspace Preparation

Clear the area you plan to blow of toys, tools, garden hoses, and other loose items that could become dangerous projectiles when hit by high-velocity air. For gas-powered models, ensure you are working in a well-ventilated outdoor space, and keep the blower away from open flames, sparks, or hot surfaces. For electric models, make sure your power outlet is grounded and free of water or moisture to avoid electrocution. (See Also:How To Put Together A Husqvarna Leaf Blower)

Blower Inspection

Do a quick visual check of your blower before starting:

• For gas models: Check the fuel tank for leaks, ensure the air filter is clean and seated properly, and confirm the spark plug wire is securely connected.
• For battery models: Verify the battery is charged, and check that the battery contacts are free of dirt or corrosion.
• For electric models: Inspect the power cord for fraying, cuts, or exposed wiring, and ensure the power switch is in the “Off” position before plugging in.

How to Turn On Stihl Leaf Blower (Gas Models)

Gas-powered Stihl blowers have the most involved starting process, but following the correct steps will ensure a quick, smooth start every time. There are two separate procedures: one for cold starts (first start of the day, or after the blower has sat for more than an hour) and one for warm starts (after short breaks of 5–15 minutes).

Cold Start Procedure (First Start of the Day or After Long Storage)

1. Fill the fuel tank with the correct fuel mix: Stihl gas-powered leaf blowers use a 2-stroke engine, which requires a mixture of unleaded gasoline and 2-stroke oil to lubricate internal parts. The standard recommended ratio is 50:1 (50 parts gasoline to 1 part Stihl-approved 2-stroke oil), but always check your owner’s manual for model-specific requirements. Never use pure gasoline, as this will destroy the engine within minutes of operation. Use only fresh fuel (no older than 30 days) to avoid clogging the carburetor with stale residue.
2. Prime the fuel primer bulb: Locate the small rubber primer bulb on the side of the blower near the fuel tank. Squeeze it slowly 3–5 times until you see fuel flowing through the clear fuel line next to the bulb. This step pushes fuel from the tank to the carburetor, eliminating the need for excessive starter cord pulls.
3. Set the choke to the “Cold Start” or “Full Choke” position: The choke restricts air flow to the carburetor, creating a richer fuel mixture that is easier to ignite when the engine is cold. This position is usually marked with a rabbit icon or the word “Cold” on the choke lever. If your model has an automatic choke, ensure it is engaged for cold starts.
4. Set the throttle to the start position: Most Stihl gas blowers have a start lock or half-throttle position for easier starting. Lock the throttle trigger in the open position (usually by pressing a small lever next to the trigger) to allow more fuel into the engine during the starting process.
5. Pull the starter cord: Hold the blower firmly on a flat, stable surface with one hand, and grip the starter cord handle with the other. Pull the cord slowly until you feel resistance, then pull quickly and firmly 1–3 times. Do not pull the cord to its full extension, as this can damage the recoil spring inside the starter mechanism.
6. Adjust the choke once the engine fires: As soon as the engine sputters to life, move the choke lever to the “Run” or “Open” position. This prevents the engine from flooding with excess fuel. Let the blower run at idle for 30 seconds to warm up before using full throttle.

Warm Start Procedure (After Short Breaks or Recent Use)

If you only stopped the blower 5–15 minutes ago, the engine is still warm, and you can skip several steps from the cold start process:

1. Skip the primer bulb: The carburetor still has fuel from the recent use, so priming is not necessary.
2. Set the choke to the “Warm Start” or half-choke position (or leave it fully open): A warm engine requires less fuel to start, so a full choke will flood the engine. Some models have a dedicated warm start choke setting; if yours does not, leave the choke fully open.
3. Set the throttle to half-open: Lock the throttle at half position for easier starting.
4. Pull the starter cord once or twice: A warm engine will start much faster, usually in 1–2 pulls. Once it starts, let it idle for 10 seconds before using full throttle to avoid stalling.

How to Turn On Stihl Leaf Blower (Battery Models)

Battery-powered Stihl blowers have the simplest starting process of all three types, with no fuel mixing or priming required. Follow these steps to get your battery blower running:

1. Charge the battery fully: Before use, ensure your Stihl AK or AP series battery is fully charged. Most batteries have an LED indicator light that shows charge level: solid green means fully charged, flashing yellow means partially charged, and solid red means the battery needs to be recharged.
2. Insert the battery into the blower: Align the battery with the slot on the bottom of the blower handle, and push it in firmly until you hear a click. This confirms the battery is properly connected to the blower’s power terminals.
3. Disengage the safety lock (if equipped): Most Stihl battery blowers have a safety lock lever next to the trigger to prevent accidental starts. Press or slide this lock to the “On” position before squeezing the trigger.
4. Press the throttle trigger to start: Squeeze the trigger gently to turn on the blower. Most models have variable speed control, so squeeze harder for more blowing power. To turn off the blower, release the trigger, and re-engage the safety lock if you will be setting the blower down.

How to Turn On Stihl Leaf Blower (Corded Electric Models)

Corded electric Stihl blowers are even more straightforward to start, with no fuel or battery required. Follow these steps:

1. Inspect the power cord for damage: Before plugging in, check the entire length of the cord for fraying, cuts, or exposed wiring. Do not use a damaged cord, as this poses a serious electrocution risk. If the cord is damaged, replace it with a manufacturer-approved replacement before use.
2. Plug the blower into a grounded outdoor outlet: Use a 3-prong grounded outlet to reduce the risk of electric shock. If you need an extension cord, use a heavy-duty outdoor-rated cord (at least 14-gauge for lengths under 50 feet) to avoid power loss or overheating.
3. Flip the power switch to the “On” position: Most Stihl corded blowers have a rocker switch on the handle. Flip this switch to turn on the blower’s motor. You will hear a quiet hum when the motor is powered on.
4. Squeeze the throttle trigger to operate: Press the trigger to start blowing air. Release the trigger to stop. Some models have a lock-on button that holds the trigger in the pressed position for extended use, reducing hand fatigue during long jobs.

Troubleshooting Common Starting Issues

Even if you follow the starting steps exactly, you may occasionally run into issues that prevent your Stihl blower from starting. Below are the most common problems and their fixes, organized by blower type.

Gas Model Starting Problems

• Blower won’t start after 3+ pulls: First, confirm you used the correct 50:1 fuel mix, and that the fuel is no older than 30 days. If the fuel is stale, drain the tank and replace it with fresh mix. Ensure the choke is set to full for cold starts, and that you primed the bulb 3–5 times. If the problem persists, check the spark plug for fouling or wear, and replace it if needed.
• Engine starts but dies immediately: This is almost always caused by a clogged air filter. Remove the air filter cover, take out the filter, and clean it with warm soapy water. Let it dry completely before reinstalling. If the engine still dies, the carburetor may be clogged: spray carburetor cleaner into the air intake while starting the blower to clear minor clogs, or have the carburetor professionally adjusted if the problem continues.
• Blower has weak power after starting: A dirty air filter or clogged spark arrestor (the small screen in the exhaust port) can restrict air flow and reduce power. Clean both parts, and check that the fuel mix is correct. If power remains low, the carburetor may need to be adjusted.

Battery and Electric Model Issues

• Battery blower won’t turn on: First, confirm the battery is fully charged and clicked securely into the blower. Clean the metal contacts on both the battery and blower with a dry cloth to remove dirt or corrosion that may be blocking power flow. If the blower still won’t turn on, the battery may be at the end of its lifespan and need replacement.
• Corded blower has low power or won’t start: Test the outlet with another device to confirm it is working. Ensure you are using a heavy-duty outdoor extension cord if needed, and that the cord is not tangled or pinched. If the outlet and cord are working properly, the blower’s internal switch may be faulty: contact Stihl customer support for repair options.

Tips for Easier Starts and Longer Blower Life

Following these simple best practices will make starting your Stihl blower easier and extend its lifespan for years of reliable use: (See Also:What Is A Leaf Blower Used For)

• Use only Stihl-approved 2-stroke oil and high-quality unleaded gasoline: Cheap, low-quality oil can leave carbon deposits in the engine, leading to hard starts and reduced performance over time. Avoid gasoline with more than 10% ethanol, as ethanol absorbs moisture and causes corrosion in the fuel system.
• Store your blower properly during off-seasons: For gas models, drain the fuel tank or add a fuel stabilizer to prevent fuel from gelling and clogging the carburetor. Store the blower in a cool, dry place away from direct sunlight. For battery models, store the battery at 40–60% charge in a cool, dry area to extend its lifespan.
• Clean the air filter after every 5–10 hours of use: A clogged air filter restricts air flow to the engine, making starting harder and reducing power. Clean it with warm soapy water, let it dry completely, and reinstall before use. Replace the filter annually for best performance.
• Check the spark plug annually: A worn or fouled spark plug is a leading cause of hard starting for gas models. Replace the spark plug once per year, or every 100 hours of use, to ensure consistent, easy starts.
• Avoid overfilling the fuel tank: Leave a small amount of empty space at the top of the fuel tank to allow for fuel expansion as the engine warms up. Overfilling can cause fuel leaks and make starting harder.

Common Mistakes to Avoid

Many common user errors can lead to hard starts, engine damage, or even injury. Avoid these mistakes to keep your blower running smoothly:

• Using the wrong fuel mix or old gasoline: This is the most common cause of starting problems for gas Stihl blowers. Never use pure gasoline, and never use fuel that is older than 30 days, as it loses volatility and clogs the carburetor.
• Over-priming the carburetor: Squeezing the primer bulb more than 5–6 times can flood the engine with fuel, making it impossible to start. Stick to 3–5 squeezes for cold starts, and skip priming entirely for warm starts.
• Pulling the starter cord to its full length: Pulling the cord all the way out can damage the recoil spring inside the starter mechanism, leading to costly repairs. Pull the cord only until you feel resistance, then give a firm, quick pull.
• Skipping pre-start safety checks: Failing to wear PPE or inspect the blower for damage can lead to serious injury. Always complete the pre-start checks outlined earlier before operating the blower.
• Storing the blower with old fuel: Stale fuel leaves sticky residue in the carburetor, leading to hard starts or complete failure to start after long storage. Always drain the fuel tank or add a fuel stabilizer before storing the blower for more than a month.

Frequently Asked Questions

Do I need to mix oil with gas for my Stihl leaf blower?

Yes, all gas-powered Stihl leaf blowers use a 2-stroke engine, which requires a fuel and oil mixture to lubricate internal moving parts. The standard recommended ratio is 50:1 (50 parts unleaded gasoline to 1 part Stihl-approved 2-stroke oil), but always check your owner’s manual for your specific model’s requirements. Never use pure gasoline, as this will cause severe engine damage within minutes of operation.

Why won’t my Stihl leaf blower start after sitting for months?

The most common cause is stale fuel that has gelled and clogged the carburetor. Drain the old fuel, replace it with a fresh 50:1 mix, and try starting again. If it still won’t start, check the spark plug for fouling or wear, clean or replace it, and spray carburetor cleaner into the air intake to clear built-up residue. If these steps don’t work, you may need to have the carburetor professionally repaired or replaced.

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

Yes, you can use regular unleaded gasoline with an octane rating of 89 or higher for all Stihl gas-powered blowers. Avoid using gasoline with more than 10% ethanol, as ethanol absorbs moisture from the air and can cause corrosion in the engine and fuel system over time. For best performance, use fresh fuel from a reputable gas station that is no older than 30 days.

How do I know if my Stihl leaf blower spark plug is bad?

A bad spark plug will cause hard starting, rough idling, sputtering, or a complete failure to start. To inspect it, remove the spark plug from the engine using a spark plug wrench, and check the electrode: if it is black, covered in carbon buildup, or has a worn-down tip, it needs to be replaced. Stihl recommends replacing the spark plug annually or every 100 hours of use to maintain optimal performance. (See Also:How To Adjust Carburetor On Craftsman Leaf Blower)

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

Yes, new Stihl leaf blowers go through a break-in period for the first 3–5 hours of use, during which internal engine parts are settling into place. During this time, you may need to use the choke for slightly longer than usual, and it may take an extra pull or two to start. This is normal, and starting will become easier once the break-in period is complete. If the blower is extremely difficult to start right out of the box, contact Stihl customer support to rule out manufacturing defects.
