It was a cold Saturday morning. I had my coffee and my boots on. A pile of oak logs was waiting for me. I grabbed my Stihl saw and pulled the cord.
The engine roared to life. It sounded strong. I squeezed the trigger. I expected the chain to spin.
But nothing happened.
The engine revved, but the chain sat still. It did not move an inch.
Have you been there? It is frustrating. You just want to get to work. You might think your saw is broken. I thought so too.
But don’t panic. A Stihl chainsaw chain not moving is a common issue. It is often a very simple fix.
Here is what I learned that day. These steps helped me get back to cutting fast.
1. Check the Brake
I have to admit, this was my first mistake. I felt a bit silly when I found it.
Stihl saws have great safety features. The main one is the chain brake. It is the black plastic paddle in front of the top handle. If the saw kicks back, this brake stops the chain.
I looked at my hand guard. It was pushed forward. The brake was on.
What I did:
- I turned the engine off.
- I pulled the black paddle back towards me.
- I heard a loud “click.”
That click is the sound of success. It means the brake is off. I started the saw again. The chain spun perfectly. Always check this first. It is easy to bump it by accident.
2. Is the Chain Too Tight?

A few weeks later, I had the same problem. But the brake was off.
I remembered I had just put on a new chain. I wanted it to be secure. So, I cranked the screw tight. Really tight.
I learned a lesson that day. If the chain is too tight, the engine cannot turn it. The friction is too high.
My Quick Test: I turned the saw off. I put on my thick gloves. I tried to pull the chain along the bar by hand. It would not budge.
The Fix:
- I loosened the side nuts.
- I turned the tension screw to the left.
- I pulled the chain up again. It lifted a little bit, then snapped back.
That is the sweet spot. It should move freely by hand.
3. Hidden Gunk in the Bar
Sometimes, the chain is fine. The problem is the track it sits in.
I took the bar off the saw. I looked closely at the groove. It was packed tight. It was full of old sawdust and sticky oil.
This gunk acts like dried glue. It grabs the chain links. It stops the Stihl chainsaw chain from moving.
How I cleaned it: I used a small flat tool. I ran it down the entire groove. A long strip of dirt came out. It was satisfying to see. Once the track was clean, the chain glided smooth.
4. The Nose Gear Was Stuck
I checked the tip of the bar next. There is a small star-shaped gear there. It is called the nose sprocket. It helps the chain turn the corner.
I tried to spin it with my finger. It was stuck solid.
I had been cutting dirty wood. Grit had jammed the little bearing. If this gear won’t turn, the whole chain stops.
The Solution:
- I sprayed some cleaner on the tip.
- I worked the gear back and forth.
- After a minute, it spun free.
Quick Problem Solver
Here is a simple chart based on my own trial and error.
| What I Saw | The Likely Reason | My Quick Fix |
| Engine revs, chain is locked | The brake is on | Pull the guard back until it clicks. |
| Chain won’t pull by hand | It is too tight | Loosen the screw until it snaps back. |
| Chain is stuck in one spot | Dirty bar groove | Scrape the gunk out of the rail. |
| Bar tip gets very hot | Stuck nose gear | Clean and oil the tip sprocket. |
Final Thoughts
There is nothing worse than a broken tool when you have work to do. But usually, a Stihl chainsaw chain not moving is just a sign. Your saw needs a little care.
For me, it is usually just the brake. Or maybe I tightened the chain too much. Now, I always do a check before I start. I spin the chain by hand (engine off!) to be sure.
Take your time. Check these simple spots. You will be making sawdust again in no time.
Stay safe out there!
FAQs – Stihl Chainsaw Chain Not Moving
Why is my Stihl chainsaw chain not moving even if the engine runs?
Check the black hand guard first. If it is forward, the brake is on. Pull it back to unlock it. This is the main cause for a Stihl chainsaw chain not moving.
Can a tight chain stop the saw from spinning?
Yes, it can. A hot chain gets long. When it cools, it shrinks tight. If your Stihl chainsaw chain is not moving, loosen the side screw. It needs room to spin freely on the bar rails.
How does dirt stop the chain from turning?
Dirt is bad for saws. Old oil and dust pack the groove. This stops the Stihl chainsaw chain from moving. It acts just like glue. Scrape the bar rail clean to let the links slide.
What if the gear at the tip of the bar is stuck?
The tip has a small gear. Grit can jam it tight. If this gear sticks, the Stihl chainsaw chain is not moving. Wash the tip with oil to make it spin. It is often just dirty or dry.
Could a bad clutch be the problem?
If the engine runs fast but the chain sits still, check the clutch drum. Worn springs can fail. This keeps the Stihl chainsaw chain not moving. You may need to buy a new part soon.
