- Understanding Fuel Mixtures: Stihl chainsaws require a specific fuel-to-oil ratio. This ensures smooth operation and longevity.
- Safety Practices: Always prioritize safety to prevent accidents.
Equipment You’ll Need
Here’s what you’ll want to have on hand:
- Stihl MS 170 Chainsaw: The star of our show!
- Protective Gear: Gloves to protect your hands, goggles for eye safety, and ear protection to guard against noise.

Safety First: Never operate a chainsaw without protective gear. Your safety is more important than anything else.
Starting Stihl MS 170: Troubleshooting Tips
So, you’ve got your chainsaw ready but it’s being stubborn? Let’s tackle some common issues together.
Tip 1: Check the Fuel System
Ever wondered why your chainsaw won’t fire up? A common culprit is often the fuel system. Let’s explore how to ensure it’s in top condition.
Understanding Fuel System Basics
The fuel system in your Stihl MS 170 is like its lifeline. It involves various components working in harmony to provide the engine with the right mix of air and fuel.
Steps to Check Fuel System
- Inspect the Fuel Tank:
- Ensure Freshness: Old fuel can lead to starting problems. If your fuel has been sitting for over a month, it’s best to replace it.
- Proper Mixing: Always adhere to Stihl’s specified fuel-to-oil ratio. Incorrect mixing can cause engine damage.
- Examine the Fuel Filter:
- Open the fuel cap and visually check the filter.
- If it’s clogged or dirty, replace it with a new one.
- Inspect Fuel Lines:
- Check for any signs of wear or damage such as cracks or leaks.
- Replace any compromised lines immediately to prevent air leaks.
Warning: When handling fuel, always work in a well-ventilated area away from open flames or sparks.
Tip 2: Check the Spark Plug
The spark plug is another key player in ensuring your chainsaw roars to life. Let’s delve into how to troubleshoot this small yet vital component.
Why is the Spark Plug Important?
The spark plug ignites the air-fuel mixture in the engine’s cylinder. Without it firing correctly, your chainsaw simply won’t start.
Steps to Inspect Spark Plug
- Remove the Spark Plug:
- Use a spark plug wrench for removal.
- Be careful not to damage the threads during this process.
- Inspect the Electrode:
- Look for carbon deposits or physical damage.
- Clean it using a wire brush or replace if necessary.
- Check Spark Plug Gap:
- Use a gap gauge to measure.
- Consult your user manual for the correct gap specifications.
- Test for Spark:
- Reattach the spark plug wire and ground it against the engine.
- Pull the starter cord; if there’s no spark, replace the plug.
Tip: Always keep a spare spark plug handy; they’re inexpensive but invaluable in emergencies.
Tip 3: Inspect the Air Filter
A clean air filter ensures your engine gets enough air to mix with fuel for combustion. Let’s look into checking this crucial component.
How Does an Air Filter Affect Performance?
A clogged air filter restricts airflow, making your engine work harder than necessary and potentially preventing it from starting at all.
Steps to Inspect Air Filter
- Access the Air Filter:
- Remove the top cover of your chainsaw.
- Gently take out the air filter element.
- Inspect and Clean:
- If it’s dusty or dirty, clean it with warm soapy water.
- Allow it to dry completely before reinstallation.
- Replace if Necessary:
- If cleaning doesn’t restore performance, replace with a new filter designed for your model.
Caution: Running without an air filter can severely damage your engine by allowing dirt inside.
My Personal Experiences with Troubleshooting
I remember one chilly morning when my MS 170 just wouldn’t start. I had a big day planned with lots of woodcutting ahead. After running through these troubleshooting steps, I realized my fuel mix was off because I’d grabbed an old canister by mistake. Lesson learned: always double-check your supplies!
Another time, during a particularly dusty job, my air filter became clogged faster than usual. It reminded me how critical regular maintenance checks are—especially in challenging conditions.
Addressing Common Questions and Concerns
What if my Stihl MS 170 still won’t start?
If you’ve run through these checks and your chainsaw remains stubbornly silent, it might be time to call in professional help or contact Stihl support for guidance.
Can environmental factors affect starting?
Yes! Cold weather can make starting more difficult due to thicker oil and colder components. Consider warming up your chainsaw indoors before use in freezing temperatures.
How often should I perform these checks?
Ideally, give your chainsaw a once-over before each use during heavy usage periods (like fall woodcutting season) or at least monthly during lighter use times.
Important Safety Precautions
Let’s talk safety again because you can’t overemphasize its importance when working with powerful tools like chainsaws:
- Always wear protective gear—gloves protect against sharp edges; goggles shield eyes from debris; ear protection saves your hearing from high noise levels.
- Ensure stability before starting—place your saw on solid ground free from obstructions.
- Never start indoors or in poorly ventilated spaces due to carbon monoxide risks.
Conclusion
By following these troubleshooting tips regularly and maintaining good overall care practices on your Stihl MS 170 chainsaw will help ensure that it runs smoothly whenever you need it most.
FAQ Section
Q: Can I use automotive oil in my Stihl MS 170?
A: No way! Stick with oils specifically formulated for two-stroke engines like those recommended by Stihl—they’re designed specifically for optimal performance without damaging internal components over time due their formulation differences compared auto oils meant car engines instead!
