Chainsaw teeth should face forward on the top of the bar and backward on the bottom, aligning with the saw’s cutting direction for effective cutting.
Using a chainsaw can be intimidating, but understanding the basics, such as which way the teeth should face, is crucial for both performance and safety. In this comprehensive guide, we will explore the importance of correctly oriented chainsaw teeth, how to identify the cutting direction, and tips for maintaining your chainsaw for optimal performance.
Understanding the Direction of Chainsaw Teeth
Chainsaw teeth, also known as cutters, are designed to perform two functions: sever the wood fibers and eject the sawdust that is produced. For these functions to be carried out effectively, it is imperative that the teeth be facing the correct direction.
Identifying the Cutting Direction
To understand the cutting direction, look closely at the teeth. You will notice that each tooth has a sharp edge with an angle – this is known as the cutting edge. The direction of this edge determines the cutting direction of the chainsaw.
| Component | Description | Direction |
|---|---|---|
| Top Plate | The flat surface on the top part of the tooth’s cutting edge. | Should face forwards. |
| Side Plate | The side surface of the tooth’s cutting edge. | Aligned with the cutting direction. |
| Gullet | The curved area below the top plate that helps to expel wood chips. | Should be toward the inside of the chain loop. |
The cutters on the chain should alternate direction. This design ensures that both sides of the cut are addressed, making for a more efficient and smoother cut.
Importance of Proper Teeth Orientation
Having your chainsaw teeth facing the correct way is essential for several reasons:
- Safety: Incorrectly oriented teeth can increase the risk of kickback.
- Performance: Correct orientation ensures an efficient and smooth cut.
- Lifespan: Properly facing teeth will reduce unnecessary wear on the chainsaw.

How to Check the Teeth Direction
Conducting a visual inspection of the chain can quickly tell you if the teeth are oriented correctly:
- Locate the cutting edges of the teeth and verify they are pointing towards the nose of the bar.
- Ensure that the angled edge of each tooth’s top plate is facing forward.
- Check that the flat part of the chain links, which travel within the bar groove, are trailing the teeth.
Steps to Correct Chainsaw Teeth Orientation
If your chainsaw teeth are facing the wrong way, follow these steps to correct their orientation:
- Turn off the chainsaw and wait for all movement to stop.
- Disconnect the spark plug wire for safety.
- Loosen the chain tension by adjusting the tensioning screw or knob.
- Remove the guide bar and chain from the chainsaw.
- Reinstall the chain with the teeth facing the correct direction.
- Reattach the guide bar and adjust the chain tension properly.
- Reconnect the spark plug wire and test the chainsaw for proper function.
