The Stihl leaf blower is a powerful tool that can make quick work of clearing leaves and debris from your yard. However, if you’re new to using a leaf blower, you may be wondering how to start it. Here are a few simple steps to get you started.
First, make sure that the leaf blower is properly assembled. The blower tube should be attached to the engine housing, and the fuel tank should be filled with fresh gasoline. Once the leaf blower is assembled, you can start it by pulling the starter cord. Pull the cord quickly and firmly, and the engine will start. If the engine doesn’t start after a few pulls, check to make sure that the spark plug is properly connected and that the fuel line is not clogged.
Once the engine is running, you can adjust the throttle to control the speed of the blower. You can also use the nozzle to direct the airflow. The nozzle can be adjusted to blow air in a wide or narrow stream, and it can also be used to blow air in a specific direction. When you’re finished using the leaf blower, simply turn off the engine and allow it to cool down before storing it.
Preparing the Stihl Leaf Blower
Before you fire up your Stihl leaf blower, it’s essential to take a few preparatory steps to ensure smooth operation and extend its lifespan:
1. Assemble the Components
Unpack your leaf blower and locate all the components, including the blower tube, handle, and fuel tank. Identify the proper assembly points and align the parts carefully. Secure the connections with the provided screws or bolts, ensuring a tight fit to prevent air leaks that can affect performance. Once assembled, inspect the connections to ensure they are secure and free from any loose components.
2. Check the Fuel Level and Mix
Locate the fuel tank and unscrew the cap. Check the fuel level and ensure it’s sufficient for your intended blowing session. If needed, refill the tank with fresh fuel. Refer to your Stihl leaf blower manual for the recommended fuel type and mixing ratio if you’re using a two-cycle engine. Measure the fuel and oil accurately to create the correct mixture ratio for optimal engine performance and longevity.
**Recommended Fuel Types for Stihl Leaf Blowers:**
| Fuel Type | Description |
|---|---|
| Unleaded Gasoline | Regular unleaded gasoline with an octane rating of 87 or higher |
| Premium Unleaded Gasoline | High-octane unleaded gasoline with an octane rating of 90 or higher |
| Two-Cycle Engine Oil | STIHL HP Ultra or STIHL MotoMix oil are recommended |
3. Insert the Battery or Power Source
Depending on your leaf blower model, it may be battery-powered or electric. For battery-powered models, insert a fully charged battery pack into the designated compartment. For electric models, ensure the power cord is securely connected to a grounded outlet. Check the condition of the battery or power cord for any damage or loose connections that could jeopardize safety and performance.
Filling the Fuel Tank
Before starting your Stihl leaf blower, it’s essential to ensure it has sufficient fuel. Follow these steps to fill the fuel tank safely:
Use a clean, fresh fuel mixture every time to prevent clogging or damage to the engine. Avoid using leftover fuel, as it can deteriorate over time. Stihl recommends using a 50:1 fuel-to-oil ratio with only high-quality unleaded gasoline with an octane rating of 89 or higher.
Locate the fuel cap on the rear of the leaf blower and remove it carefully. Insert the fuel funnel into the tank opening to avoid spills and overfilling. Pour the pre-mixed fuel slowly into the tank, filling it up to the bottom of the fuel neck, approximately 0.5 liters. Avoid overfilling, as excess fuel can leak and create a fire hazard.
Verify the fuel level by holding the leaf blower upright and checking the translucent side of the fuel tank. If the fuel is at or slightly below the bottom of the fuel neck, you have added the correct amount.
Wipe away any spilled fuel from the leaf blower or surrounding area to prevent fire or health hazards.
After filling, securely tighten the fuel cap to prevent leaks during operation.

| Fuel Type | Oil Ratio |
|---|---|
| Unleaded Gasoline (89+ Octane) | 50:1 |
Priming the Engine
Priming the engine is an essential step before starting your Stihl leaf blower. Without priming, the engine may not receive enough fuel to start or run smoothly. Here are detailed instructions on how to prime the engine:
1. Locate the Primer Bulb
The primer bulb is a small rubber bulb located near the engine’s carburetor. It is usually marked with an arrow or the word “Prime.” Press the primer bulb 5-10 times until you feel resistance.
2. Open the Choke
The choke is a lever or knob that controls the airflow into the carburetor. Open the choke by moving the lever or knob to the “open” position.
3. Pull the Starter Cord
a. Electric Start:
* Insert the key and turn it to the “Start” position.
* Hold the key until the engine starts, or for a maximum of 10 seconds.
* If the engine doesn’t start, release the key and wait a few seconds before trying again.
b. Manual Start:
* Grip the starter cord firmly with your dominant hand.
* Slowly pull the cord until you feel resistance.
* Quickly pull the cord with a strong, steady motion.
* Repeat step 4 if necessary.
Setting the Choke
The choke is a lever that controls the flow of fuel to the engine. When the choke is set to the “on” position, it restricts the flow of air to the carburetor, which creates a richer fuel mixture. This richer fuel mixture is necessary for starting a cold engine, as it helps to vaporize the fuel and make it more combustible. Once the engine has started, the choke should be set to the “off” position.
To set the choke, locate the choke lever on the side of the carburetor. The lever will typically have two positions: “on” and “off.” Move the lever to the “on” position.
Move the choke lever to the “off” position once the engine has started.
If the engine does not start after setting the choke, you may need to adjust the idle speed screw. The idle speed screw is located on the carburetor, and it controls the speed of the engine when it is idling. Turn the idle speed screw clockwise to increase the idle speed, or counterclockwise to decrease the idle speed.
| Choke Position | Description |
|---|---|
| On | Restricts airflow, creating a richer fuel mixture for starting a cold engine |
| Off | Allows normal airflow, providing a leaner fuel mixture for running the engine after it has started |
If the engine still does not start, you may need to check the fuel line or spark plug. The fuel line may be clogged, or the spark plug may be fouled. If you are not familiar with these components, it is best to consult a qualified mechanic.
Pulling the Starter Cord
To start your Stihl leaf blower, follow these steps:
- Make sure the engine switch is in the “Start” position.
- Place the leaf blower on a flat, stable surface.
- Hold the blower firmly with one hand.
- Grasp the starter cord with your other hand and pull it slowly until you feel resistance.
- Then, give the cord a quick, strong pull to start the engine.
Tips for Pulling the Starter Cord
Here are a few tips to help you pull the starter cord effectively:
- Do not pull the cord too hard or too fast. This can damage the starter cord or the engine.
- If the cord does not start the engine after a few pulls, stop pulling and wait a few minutes for the engine to cool down.
- If the engine still does not start, check the fuel level and spark plug.
Once the engine is running, you can adjust the throttle lever to control the blower’s speed.
Adjusting the Throttle
Once your Stihl leaf blower is assembled and fueled, you need to adjust the throttle to get it running smoothly. Follow these steps to adjust the throttle:
1. Locate the Throttle Lever
The throttle lever is typically located on the right side of the blower’s handle. It has three settings: low, high, and stop.
2. Set the Throttle to “Low”
Start by setting the throttle lever to the “low” setting. This will help prevent the blower from starting too quickly.
3. Pull the Starter Cord
With the throttle lever set to “low,” pull the starter cord until the engine starts.
4. Adjust the Choke
If the engine does not start immediately, you may need to adjust the choke. Push the choke lever forward to close the choke and aid in starting. Once the engine starts, gradually release the choke lever until the engine runs smoothly.
5. Adjust the Throttle Speed
Once the engine is running, you can adjust the throttle speed using the throttle lever. Increase the throttle speed by moving the lever towards the “high” setting. Decrease the speed by moving the lever towards the “low” setting.
6. Fine-Tune the Throttle
For optimal performance, fine-tune the throttle by adjusting the high-speed and low-speed idle screws. These screws are located on the side of the carburetor. Turn the high-speed idle screw clockwise to increase the high-speed idle speed. Turn the low-speed idle screw clockwise to increase the low-speed idle speed. Refer to the manufacturer’s instructions for specific adjustments.
Setting Use Low For light-duty blowing, such as leaves on a driveway High For heavy-duty blowing, such as wet leaves or debris Using the Purge Bulb
The purge bulb is a small, rubber bulb located on the side of the leaf blower. Its purpose is to manually pump fuel into the carburetor, which is necessary for starting the engine. To use the purge bulb:
- Locate the purge bulb on the side of the leaf blower.
- Squeeze the bulb repeatedly until it becomes firm.
