How to Start a Stihl Pole Saw (5 Expert Tips for Seamless Use)

Did you know that improper chainsaw starting techniques are a leading cause of injuries among both professional loggers and home users? That’s a statistic that hit home for me years ago when a friend of mine ended up with a nasty cut after a chainsaw kickback during a botched start. It’s a stark reminder that even seemingly simple tasks like starting a chainsaw, especially a pole saw where you’re working at a distance, require respect and precision.

I’ve spent over 20 years in the woods, from felling trees as part of a forestry crew to prepping firewood for my own home, and I’ve learned that mastering the basics is crucial for safety and efficiency.

This guide will walk you through the process of starting a Stihl pole saw, sharing five expert tips that I’ve honed over the years. We’ll cover everything from understanding the saw’s components to troubleshooting common starting problems. My aim is to give you the knowledge and confidence to use your pole saw safely and effectively.

Understanding Your Stihl Pole Saw: A Foundation for Success

Before we dive into the starting process, it’s essential to understand the key components of your Stihl pole saw. This knowledge will not only help you start the saw correctly but also diagnose any issues that might arise.

• Engine: The heart of your pole saw is typically a two-stroke engine, which requires a mix of gasoline and oil. Understanding the correct fuel mixture is crucial for engine longevity and performance.
• Fuel Tank: This holds the fuel mixture. It’s important to use fresh fuel and the correct oil-to-gas ratio (usually 50:1 for Stihl products, but always check your owner’s manual).
• Primer Bulb: A small, clear bulb that you press to draw fuel into the carburetor. This is essential for starting, especially after the saw has been sitting for a while.
• Choke: A lever or switch that restricts airflow to the engine, creating a richer fuel mixture for starting.
• Ignition Switch: Controls the flow of electricity to the spark plug. Make sure it’s in the “on” position before attempting to start the saw.
• Starter Cord: Pulling this cord spins the engine, hopefully initiating the combustion process.
• Cutting Head: This includes the bar and chain. Ensure the chain is properly tensioned and sharpened for optimal cutting performance.
• Pole: The extension that allows you to reach high branches. It’s important to inspect the pole for any damage or loose connections before use.

Key Terms:

• Two-Stroke Engine: An engine that completes a power cycle with two strokes of the piston. These engines require a fuel mixture of gasoline and oil.
• Carburetor: A device that mixes air and fuel to create a combustible mixture.
• Choke: A mechanism that restricts airflow to the engine, creating a richer fuel mixture for starting.
• Kickback: A sudden, uncontrolled upward or backward motion of the chainsaw bar, often caused by the tip of the bar contacting a solid object.

Tip #1: The Perfect Fuel Mixture – The Lifeblood of Your Engine

The fuel mixture is arguably the most critical aspect of starting and maintaining a Stihl pole saw. I’ve seen countless engines ruined by incorrect fuel ratios or stale fuel. Stihl engines typically require a 50:1 fuel-to-oil ratio. This means 50 parts gasoline to 1 part two-stroke oil.

Why is the fuel mixture so important?

• Lubrication: Two-stroke engines rely on the oil in the fuel mixture for lubrication. Without the correct amount of oil, the engine’s internal components will wear down quickly, leading to premature failure.
• Combustion: The correct fuel-to-air ratio is essential for efficient combustion. Too much oil can foul the spark plug, while too little oil can lead to engine overheating and damage.

How to Mix Fuel Correctly:

1. Use Fresh Gasoline: Gasoline can degrade over time, especially if it contains ethanol. I recommend using gasoline with an octane rating of 89 or higher and avoiding gasoline with more than 10% ethanol. If possible, use ethanol-free gasoline.
2. Use High-Quality Two-Stroke Oil: Stihl recommends using their own brand of two-stroke oil, but any high-quality oil specifically formulated for two-stroke engines will work.
3. Measure Accurately: Use a fuel mixing container with clear markings for gasoline and oil. I prefer to use a dedicated measuring cup for the oil to ensure accuracy.
4. Mix Thoroughly: Pour the gasoline and oil into the mixing container and shake vigorously for at least 30 seconds to ensure they are properly mixed.
5. Label and Date: Label the fuel container with the date and the fuel-to-oil ratio. This will help you keep track of how old the fuel is and prevent accidental use in other equipment.

My Experience:

I once had a client who consistently used the wrong fuel mixture in his Stihl chainsaw. He thought he was saving money by using less oil, but he ended up spending far more on repairs. After switching to the correct fuel mixture, his chainsaw ran much smoother and lasted significantly longer.

Data and Insights:

According to Stihl’s technical data, using an incorrect fuel mixture can reduce engine life by up to 50%. This is a significant cost to consider when deciding whether to use the correct fuel ratio.

Cost Analysis:

• High-Quality Two-Stroke Oil: $10-$15 per quart
• Fuel Mixing Container: $10-$20
• Potential Engine Repair Costs: $100-$500+

Strategic Advantage:

Using the correct fuel mixture is a small investment that can save you a significant amount of money in the long run by preventing engine damage and extending the life of your Stihl pole saw.

Tip #2: Priming and Choking – Setting the Stage for Ignition

Priming and choking are essential steps in preparing your Stihl pole saw for starting, especially when the engine is cold. These actions ensure that the carburetor receives the necessary fuel to initiate combustion.

Priming:

The primer bulb is a small, clear bulb located on the carburetor. Pressing this bulb draws fuel from the fuel tank into the carburetor, ensuring that there is fuel available for starting.

How to Prime:

1. Locate the Primer Bulb: It’s usually a transparent or slightly colored bulb.
2. Press the Bulb: Press the primer bulb firmly and repeatedly until you see fuel flowing through it. This usually takes 5-10 presses.
3. Avoid Over-Priming: Be careful not to over-prime the engine, as this can flood the carburetor and make it difficult to start. If you see fuel overflowing from the carburetor, you’ve likely over-primed it.

Choking:

The choke restricts airflow to the engine, creating a richer fuel mixture that is easier to ignite when the engine is cold.

How to Choke:

1. Locate the Choke Lever: The choke lever is usually located near the carburetor. It may be marked with symbols or letters indicating the “choke” and “run” positions.
2. Engage the Choke: Move the choke lever to the “choke” position. This will typically close off the airflow to the engine.
3. Starting a Warm Engine: If the engine is already warm, you may not need to use the choke. Try starting the saw without the choke first.

My Experience:

I once spent hours trying to start a Stihl pole saw that had been sitting unused for several months. I had forgotten to prime the engine properly, and the carburetor was completely dry. After a few minutes of priming, the saw started right up.

Original Case Study:

I was helping a neighbor clear some branches from his property after a storm. His Stihl pole saw wouldn’t start, even after repeated attempts. I checked the fuel mixture, which was fine, and then noticed that he hadn’t primed the engine. After priming the engine and engaging the choke, the saw started on the first pull.

Troubleshooting:

• Engine Won’t Start After Priming: Check the spark plug to make sure it’s clean and dry. If it’s wet, you may have over-primed the engine. Remove the spark plug and pull the starter cord several times to clear the excess fuel.
• Engine Starts But Dies Immediately: This could be due to an incorrect choke setting. Try adjusting the choke lever to the “run” position once the engine starts.

Benefits:

• Ensures fuel reaches the carburetor for starting.
• Creates a richer fuel mixture for easier ignition.
• Reduces the number of pulls required to start the saw.

Tip #3: Mastering the Starting Technique – Smooth and Steady Wins the Race

The starting technique is where many people struggle, especially with pole saws due to their weight and balance. A smooth, controlled pull is far more effective than a jerky, forceful one.

The Correct Starting Stance:

1. Position the Saw: Place the pole saw on a stable surface, ensuring the cutting head is clear of any obstructions.
2. Secure the Saw: Hold the saw firmly with one hand on the pole, near the engine housing. Use your foot to stabilize the base of the pole if necessary.
3. Engage the Starter: Slowly pull the starter cord until you feel resistance. This engages the engine’s flywheel.
4. Pull Smoothly: Give the starter cord a brisk, smooth pull. Avoid yanking the cord, as this can damage the starter mechanism.
5. Repeat if Necessary: If the engine doesn’t start on the first pull, repeat the process. After a few pulls, disengage the choke (if used) and try again.

Safety Considerations:

• Wear Gloves: Protect your hands from blisters and cuts.
• Wear Eye Protection: Debris can fly up during starting.
• Clear the Area: Ensure there are no people or obstacles within the saw’s range.

My Experience:

I used to struggle with starting my Stihl chainsaw, often yanking the starter cord with all my might. I eventually learned that a smooth, controlled pull is far more effective and less stressful on the saw.

Original Insights:

Many people make the mistake of pulling the starter cord too quickly or forcefully. This can cause the cord to break or damage the starter mechanism. A smooth, steady pull allows the engine to build up momentum gradually, increasing the chances of a successful start.

Troubleshooting:

• Starter Cord is Difficult to Pull: This could be due to a tight engine or a damaged starter mechanism. Try lubricating the starter cord and flywheel. If the problem persists, consult a qualified technician.
• Starter Cord Breaks: This is usually caused by yanking the cord too forcefully. Replace the starter cord and practice a smoother pulling technique.

Benefits:

• Reduces the risk of injury.
• Minimizes wear and tear on the saw.
• Increases the chances of a successful start.

Tip #4: Chain and Bar Maintenance – Ensuring Smooth Cutting and Safe Operation

A dull or improperly tensioned chain can make starting and operating a Stihl pole saw incredibly difficult and dangerous. Regular maintenance of the chain and bar is essential for safe and efficient cutting.

Chain Tension:

The chain should be snug on the bar but still able to be pulled around by hand.

How to Check and Adjust Chain Tension:

1. Wear Gloves: Protect your hands from the sharp chain.
2. Loosen the Bar Nuts: Use the appropriate wrench to loosen the bar nuts that hold the bar in place.
3. Adjust the Tensioning Screw: Locate the chain tensioning screw, usually located on the side of the saw. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.
4. Check the Tension: The chain should be snug on the bar but still able to be pulled around by hand. There should be no more than 1/8 inch of sag in the middle of the bar.
5. Tighten the Bar Nuts: Once the chain is properly tensioned, tighten the bar nuts securely.

Chain Sharpening:

A sharp chain cuts more efficiently and reduces the risk of kickback.

How to Sharpen the Chain:

1. Use the Correct File: Use a chainsaw file that is the correct size for your chain.
2. Secure the Chain: Use a chain vise to hold the chain securely in place.
3. File Each Cutter: File each cutter at the correct angle and depth. Follow the manufacturer’s instructions for your chain.
4. Check the Depth Gauges: Use a depth gauge tool to ensure that the depth gauges are set correctly.
5. Sharpen Regularly: Sharpen the chain regularly to maintain its cutting performance.

Bar Maintenance:

The bar should be cleaned and lubricated regularly to prevent wear and tear.

How to Maintain the Bar:

1. Clean the Bar: Use a wire brush to clean the bar grooves and oil holes.
2. Lubricate the Bar: Use chainsaw bar and chain oil to lubricate the bar and chain.
3. Check for Wear: Check the bar for wear and damage. Replace the bar if it is worn or damaged.

My Experience:

I once neglected to sharpen my chainsaw chain for too long, and it became so dull that it was nearly impossible to cut through wood. I learned my lesson and now sharpen my chain regularly.

Original Case Study:

I was teaching a chainsaw safety course, and one of the students was struggling to cut through a log. I checked his chainsaw and found that the chain was dull and the bar was dry. After sharpening the chain and lubricating the bar, he was able to cut through the log with ease.
