Pull the starter rope – that’s how to start a Stihl saw once you’ve set the controls right. The exact steps change a bit between models, but the basic idea is the same for all of them.
I’ve started dozens of these saws over the years. It can feel tricky the first few times you try it.
But once you know the pattern, it gets easy. I’ll walk you through the whole process step by step.
This guide covers every model from the small MS 170 to the big MS 661. Let’s get your saw running.
What You Need to Know Before You Start
First, check your saw’s fuel mix. Stihl saws need a special gas and oil blend.
Use fresh fuel with a two-stroke oil mix. Old gas can cause starting problems right away.
Look at the chain brake too. Make sure it’s not engaged when you try to start the saw.
The chain should move freely. If the brake is on, the engine won’t turn over at all.
Find a flat, clear spot to work. You need good footing to pull the starter rope hard.
I like to put the saw on the ground for the first start of the day. It’s the safest way.
The Step-by-Step Guide to Start Your Stihl Saw
Here is the full method to start a Stihl saw. Follow these steps in order.
First, press the primer bulb if your model has one. You’ll see fuel move through the clear line.
Next, set the master control lever to the cold start position. This is often the choke setting.
Now, place the saw on the ground. Hold it down with your left hand on the front handle.
Put your right foot through the rear handle for stability. This gives you a solid grip.
Pull the starter rope with a quick, strong motion. Do this until the engine tries to fire.
This is how to start a Stihl saw from a completely cold state. The Occupational Safety and Health Administration says to always secure the saw before pulling.
Starting a Warm Stihl Saw
The process changes if your saw is already warm. You skip a few steps here.
Move the master control lever to the run position. Do not use the choke setting.
You might need to set it to the half-throttle position instead. Check your owner’s manual.
Hold the saw the same secure way. Pull the starter rope one to three times.
A warm engine should start right up. If it doesn’t, something else might be wrong.
This is how to start a Stihl saw after a short break. It’s much faster than a cold start.
Knowing this difference saves you time and effort. It also prevents flooding the engine.
Using the Master Control Lever Correctly
This lever is the key to the whole process. You must understand its three positions.
The choke position is for a cold start. It gives the engine a rich fuel mixture.
The half-throttle position is the warm start setting. It gives a small burst of gas.
The run position is for normal operation. The engine runs at idle speed here.
Learning how to start a Stihl saw means mastering this lever. It controls the fuel and ignition.
Move it to the right spot for your saw’s temperature. This is the most common mistake I see.
Refer to the decal on your saw if you forget. It shows the exact lever positions.
Common Problems and How to Fix Them
What if the saw doesn’t start? Let’s troubleshoot the usual issues.
First, check for a flooded engine. This happens if you pull too many times on choke.
To fix it, move the lever to run and hold the throttle wide open. Pull the starter rope many times.
This clears the extra fuel from the cylinder. It’s how to start a Stihl saw after flooding it.
Next, check your spark plug. A dirty or wet plug won’t create a spark.
According to the Environmental Protection Agency, small engine maintenance helps reduce emissions. A clean plug starts easier.
Finally, make sure your fuel is fresh. Gas older than 30 days can cause big problems.
Safety Tips for Starting Your Saw
Safety comes first every single time. Never forget these rules.
Always start the saw on the ground. Never try to start it while holding it in the air.
Keep people and pets far away. The chain can kick back when the engine fires.
Wear your safety gear. This includes eye protection, gloves, and ear defenders.
Clear the area of trip hazards. You need a clean pull on the starter rope.
This is the safe way to start a Stihl saw. The National Institute for Occupational Safety and Health stresses proper chainsaw handling.
Make these habits automatic. Your fingers will thank you later.
Maintenance for Easier Starting
A well-kept saw starts with less effort. Do these simple tasks often.
Clean the air filter every few uses. A dirty filter chokes the engine.
Use the right fuel mix. Stihl recommends a 50:1 ratio for most newer saws.
Old saws might need 40:1. Check your manual to be sure.
Keep the spark arrestor screen clean. This little screen is in the muffler.
It can clog with carbon over time. A clean saw knows how to start a Stihl saw cycle quickly.
Store your saw with an empty fuel tank if it will sit for months. This prevents gumming.
Special Tips for Different Stihl Models
Some models have extra features. Here’s what you need to know.
The MS 170 and MS 180 have a simpler control. They often lack a separate choke.
You just set the lever to start and pull. The system does the rest for you.
Big professional saws like the MS 661 have a decompression valve. Press this button before starting.
It makes pulling the rope much easier. This is how to start a Stihl saw with a big engine.
Models with M-Tronic technology adjust themselves. You just set the lever and pull.
The computer sets the fuel mix. It’s a great system for beginners.
No matter the model, the core steps are the same. Set, secure, and pull.
What to Do After the Saw Starts
Your job isn’t done once the engine fires. You need to warm it up right.
Let the saw idle for 30 seconds to a minute. This lets oil circulate.
Then, gently squeeze the throttle a few times. Listen for a smooth engine sound.
Check that the chain isn’t moving at idle. If it spins, adjust the idle speed screw.
Now you’re ready to cut. Always let the saw reach full speed before touching wood.
This proper warm-up is part of how to start a Stihl saw for a long life. The engine needs that time.
Rushing this step can cause early wear. Be patient for the first cut of the day.
Frequently Asked Questions
Why won’t my Stihl saw start?
Check three things first: old fuel, a dirty air filter, or a flooded engine. These are the most common causes of a saw that won’t run.
How do I start a Stihl chainsaw after it sits all winterh3>
Drain any old fuel from the tank and carburetor. Put in fresh fuel mix. You may need to pull the starter rope many times to get fuel flowing again.
What is the correct starting position for the master control lever?
For a cold engine, move it to the choke position. For a warm engine, move it to the run or half-throttle position. The decal on your saw shows the exact spot.
Can I start my Stihl saw without the chain brake on?
Yes, you must disengage the chain brake to start the saw. The brake locks the clutch, so the engine can’t turn over if it’s engaged.
How many pulls should it take to start a Stihl saw?
A well-maintained saw should start in 3-5 pulls when cold. A warm saw should start on the first or second pull. Many more pulls means something is wrong.
Do I need to use the primer bulb every time?
Only on a cold start. Press it until you see fuel fill the clear line. For a warm start, you usually don’t need to touch the primer bulb at all.
