Putting a chainsaw chain on the wrong way is a common mistake that can lead to poor cutting, kickback dangers, and even damage to your saw. Knowing the correct chainsaw chain direction is essential for safe and efficient operation.
In this guide, we’ll cover:
✔ How to check your chain direction
✔ Why the correct direction matters
✔ How to fix an incorrectly installed chain
✔ FAQs about chainsaw chain orientation
The direction of chainsaw chain movement is determined by the cutting teeth (cutters). Here’s how to verify yours is on correctly:
1. Look at the Cutting Teeth
- The sharp, pointed edge of each cutter should face forward in the direction of rotation.
- The flat side of the cutter should face backward.
2. Check the Drive Links (Bottom of the Chain)
- The drive links (the part that fits into the bar groove) should point in the same direction as chain movement.
3. Follow the Rotation Arrow (If Present)
- Some chainsaw bars have a small arrow indicating rotation direction.
- The chain’s teeth should follow this arrow.
How to Identify the Correct Chainsaw Chain Direction
Why Does Chainsaw Chain Direction Matter?
Installing the chain backward causes:
❌ No cutting – The teeth won’t bite into wood.
❌ Excessive wear – The chain and bar will heat up and dull quickly.
❌ Increased kickback risk – A backward chain can catch and jerk violently.
How to Fix an Incorrectly Installed Chainsaw Chain
If your chain is on backward, follow these steps:
1. Release the Chain Tension
- Loosen the bar nuts and adjust the tensioning screw.
2. Remove the Chain
- Slide the chain off the bar.
3. Flip the Chain
- Rotate it so the cutting teeth face forward.
4. Reinstall & Adjust Tension
- Place the chain back on the bar, ensuring proper alignment.
- Tighten the bar nuts and adjust tension (should lift slightly from the bar).
FAQs About Chainsaw Chain Direction
How can I tell if my chainsaw chain is on backward?
If the saw smokes, doesn’t cut, or feels sluggish, the chain may be reversed.
Do all chainsaw chains rotate the same way?
Yes, nearly all chainsaws rotate clockwise (when viewed from the side).
Can I run my chainsaw with the chain backward?
No! It won’t cut and can damage the saw. Always fix it before use.
Does chain direction affect sharpening?
Yes! Always file cutters in their natural forward-facing angle.
Final Tips for Correct Chainsaw Chain Direction
✔ Double-check direction before installing a new chain.
✔ Follow the bar’s rotation arrow (if present).
✔ Test the chain by hand-spinning it before starting the saw.
Installing the chain correctly ensures smoother cuts, longer chain life, and safer operation.
