Got a pile of leaves or debris that needs taming? You’ve got a Stihl blower, a powerful tool for tackling yard work. But before you can unleash its full potential, you need to know how to get it running smoothly.
Many new Stihl blower owners, or even seasoned users facing a new model, can feel a bit daunted by the starting process. It’s not as simple as just pulling a cord, and getting it wrong can be frustrating. Don’t worry, though! We’re here to walk you through the exact steps to ensure you can start your Stihl blower with confidence every single time.
Mastering Your Stihl Blower: A Step-by-Step Starting Guide
Your Stihl blower is a fantastic piece of equipment, designed for efficiency and power. But like any engine, it needs a proper startup sequence to run reliably. We’ll break down the process into simple, actionable steps, covering everything from pre-start checks to troubleshooting common issues. Whether you have a handheld model or a backpack blower, these principles will apply.
Before You Even Think About Starting: Essential Pre-Start Checks
A smooth start begins long before you pull the starter cord. Taking a few moments for these checks will save you time and potential headaches. Think of it as preparing your tool for success!
1. Fuel and Oil Mixture: The Lifeblood of Your Blower
Most Stihl blowers are powered by a 2-stroke engine. This means they require a specific mixture of gasoline and 2-stroke oil. Using the wrong mixture or pure gasoline can severely damage your engine.
- Fuel Type: Always use fresh, unleaded gasoline with an octane rating of 89 or higher. Avoid using E10 or E15 fuel if possible, as it can degrade fuel lines and other components over time. If E10 is all you can get, consider using a fuel stabilizer.
- Oil Type: Use a high-quality, air-cooled 2-stroke engine oil specifically designed for 2-stroke engines. Stihl offers its own branded oil, which is an excellent choice.
- Mixing Ratio: The most common ratio for Stihl blowers is 50:1. This means 50 parts gasoline to 1 part 2-stroke oil. Always check your owner’s manual for the exact ratio recommended for your specific model, as it can vary.
- Mixing Container: Use a clean, approved fuel mixing container. Never mix fuel directly in the blower’s fuel tank.
- How to Mix: Pour the correct amount of oil into the container first, then add the gasoline. Seal the container and shake it thoroughly to ensure a consistent mixture.
Pro Tip: Only mix enough fuel for your immediate needs. Stale fuel can cause starting problems. If you’re unsure about your fuel mixture, it’s better to err on the side of caution and mix a fresh batch.
2. Air Filter: Keeping the Lungs of Your Blower Clean
A clogged air filter restricts airflow, making it harder for the engine to start and run efficiently. Regularly inspecting and cleaning your air filter is crucial. (See Also: how much is a blower motor for a furnace)
- Location: The air filter is usually located under a cover on the blower’s housing. Consult your manual if you’re unsure.
- Inspection: Remove the filter and hold it up to a light source. If you can’t see light through it, or if it appears excessively dirty or damaged, it’s time for a clean or replacement.
- Cleaning: For paper filters, gently tap out debris. For foam filters, you can wash them with mild soap and water, ensuring they are completely dry before reinstallation. Some Stihl models might have specific cleaning instructions for their filters.
3. Spark Plug: The Ignition Source
A fouled or improperly gapped spark plug can prevent your blower from firing up. It’s a simple component that plays a vital role.
- Access: The spark plug is typically found near the engine cylinder, usually covered by a protective boot.
- Removal: Use a spark plug wrench to carefully remove the plug.
- Inspection: Check for signs of wear, damage, or heavy carbon buildup. A healthy spark plug will have a light tan or gray color.
- Gap: Ensure the spark plug gap is set to the manufacturer’s specifications. You can use a feeler gauge for this. Your owner’s manual will provide the correct gap.
- Replacement: If the plug is damaged or worn, replace it with a new one of the correct type.
4. General Inspection: A Quick Once-Over
Before you proceed, give your blower a quick visual check:
- Damage: Look for any loose parts, cracks, or damage to the housing, starter cord, or fuel lines.
- Debris: Ensure the blower housing and air intake areas are free of any obstructions like leaves or dirt.
The Starting Sequence: How to Get Your Stihl Blower Running
Now that your blower is prepped, let’s get to the actual starting process. Most Stihl blowers follow a similar pattern, but always refer to your specific model’s manual for absolute certainty.
Step 1: Prime the Engine (if Equipped)
Many Stihl blowers have a primer bulb. This small, clear bulb is designed to draw fuel into the carburetor, making it easier to start a cold engine.
- Locate the Primer Bulb: It’s usually a rubber bulb located near the carburetor.
- Press it Repeatedly: Press the primer bulb 5-10 times, or until you see fuel flowing through it and returning to the fuel tank. You’ll notice the bulb filling with fuel.
- If No Primer Bulb: Some older or simpler models might not have a primer. In this case, you’ll rely more on the choke and repeated pulls.
Step 2: Engage the Choke
The choke enriches the fuel-air mixture, which is necessary for starting a cold engine. It’s like giving the engine a little extra fuel to get going.
- Locate the Choke Lever: This is usually a lever or switch near the carburetor or on the handle.
- Set to ‘Cold Start’ or ‘Full Choke’: The choke will have settings like ‘I’ (run), ‘II’ (cold start/full choke), or symbols indicating its position. For a cold engine, set it to the full choke position.
- What if the Engine is Warm? If the engine is already warm, you might only need to set the choke to the ‘half choke’ or ‘run’ position, or even skip the choke altogether. Refer to your manual.
Step 3: Engage the Master Control Lever (if Equipped)
Some Stihl models have a master control lever that combines the on/off switch and choke function. Ensure this is set to the appropriate starting position. (See Also: how to test a blower motor resistor)
Step 4: Pull the Starter Cord
This is the moment of truth! You’ll need to pull the starter cord with a firm, consistent motion.
- Grip the Handle: Firmly grasp the starter cord handle.
- Pull with Force: Pull the cord out with a strong, smooth, and continuous motion. Avoid short, jerky pulls.
- Listen for the ‘Pop’: For a cold start with the choke engaged, you’ll typically hear the engine sputter or ‘pop’ after a few pulls. This indicates it’s trying to start.
Step 5: Disengage the Choke (partially or Fully)
Once you hear that ‘pop’ or sputter, it’s time to adjust the choke to allow more air into the engine.
- Move to Half Choke: Immediately after the ‘pop’, move the choke lever to the ‘half choke’ or ‘run’ position.
- Pull Again: Pull the starter cord again. The engine should now run.
- If it Stalls: If the engine stalls again, you might need to repeat the ‘pop’ and choke adjustment process. Sometimes, a second or third attempt is necessary.
- Fully Disengage: Once the engine is running steadily, ensure the choke is fully disengaged and set to the ‘run’ position.
Step 6: Allow the Engine to Warm Up
Let your Stihl blower run for a minute or two at idle before applying full throttle. This allows the engine to reach its optimal operating temperature and ensures smooth performance.
Troubleshooting Common Starting Problems
Even with the best preparation, sometimes your Stihl blower might refuse to start. Don’t get discouraged! Here are some common issues and how to address them:
1. Engine Won’t Fire at All
- Check Fuel: Is there fresh fuel in the tank? Is the fuel mixture correct?
- Choke Position: Is the choke set correctly for a cold start?
- Spark Plug: Is the spark plug properly connected? Is it fouled or damaged? Try cleaning or replacing it.
- Primer Bulb: Did you prime the engine properly?
- On/Off Switch: Is the on/off switch in the ‘on’ position?
2. Engine Sputters and Dies
- Choke Adjustment: You might be leaving the choke on too long, or not disengaging it soon enough. Try disengaging it sooner after the initial sputter.
- Air Filter: A dirty air filter can cause this. Clean or replace it.
- Fuel Delivery: Ensure the fuel lines are not kinked and that fuel is reaching the carburetor.
3. Engine Starts but Runs Rough or Lacks Power
- Air Filter: This is a common culprit for rough running.
- Spark Arrestor Screen: The spark arrestor screen in the muffler can become clogged with carbon. Check your manual for instructions on how to access and clean it.
- Fuel Filter: If your model has an inline fuel filter, it might be clogged.
- Carburetor: The carburetor may need to be adjusted or cleaned. This is a more advanced task, and if you’re not comfortable, it’s best to have a professional service it.
4. Starter Rope Won’t Pull or Feels Stuck
- Obstruction: Check for any debris jamming the recoil starter mechanism.
- Engine Seized: In rare cases, the engine itself might be seized. This is a serious issue that requires professional attention.
Important Safety Reminders
Always prioritize safety when operating any power equipment. Before starting your Stihl blower:
- Wear Protective Gear: Always wear safety glasses or goggles, hearing protection, and sturdy footwear. Gloves are also recommended.
