Chainsaw teeth should face forward on the top of the bar and backward on the bottom, ensuring effective cutting and optimal performance.
If you’re a homeowner, woodworker, or outdoors enthusiast, understanding which way the teeth on a chainsaw go is essential for both efficient cutting and safety. In this comprehensive guide, we’ll cover everything you need to know about the correct orientation of chainsaw teeth, so you can confidently maintain and use your chainsaw.
The Importance of Proper Chainsaw Teeth Orientation
Correctly installed chainsaw teeth are crucial for various reasons:
- Efficiency: Properly oriented teeth ensure optimal cutting performance, reducing the time and effort required to cut through wood.
- Safety: A chainsaw with incorrectly installed teeth can lead to dangerous kickbacks, which are one of the main causes of chainsaw-related injuries.
- Tool Longevity: When the teeth are facing the right direction, it results in even wear and tear, extending the lifespan of your chainsaw chain.
Identifying the Direction of Chainsaw Teeth
To determine the right direction for the teeth on a chainsaw chain, you should understand the two types of teeth:
- Cutters: These are the sharp, blade-like teeth responsible for the cutting action as the chain moves around the bar.
- Rakers: These protrusions regulate the depth of the cut by preventing the cutters from digging too deep into the wood.
With these definitions in mind, let’s focus on how to tell if your chainsaw teeth are correctly aligned:
| Chain Part | Orientation Details |
|---|---|
| Cutters | The sharp edge of the cutters should face forward towards the direction of the chain rotation. |
| Rakers | Rakers should be set slightly lower than the cutters to permit the cutters to engage with the wood. |
Note: The chain rotates clockwise when viewed from the top of the chainsaw bar. This means the cutters on the top of the bar should be facing forward, away from the main body of the saw.
How to Install a Chainsaw Chain Correctly
When installing a new chain or repositioning an old one, following the correct installation steps is critical for safety and performance. Here’s a step-by-step guide:
- Power off the chainsaw and ensure it’s cool to the touch before handling it.
- Release the chainsaw’s brake and remove the side plate to access the chain.
- Place the chain around the saw’s bar, making sure the cutters are facing forward on the top edge of the bar.
- Align the chain with the sprocket and guide bar’s groove.
- Replace the side plate and tension the chain by turning the tensioning screw until the chain fits snugly against the bar.
- Double-check the direction of the teeth before using the chainsaw.
Always consult your chainsaw’s manual for specific instructions related to your model.

What to Do If the Chainsaw Teeth Are in the Wrong Direction
Should you find that the chainsaw teeth are installed backward, it’s imperative to re-install the chain correctly. To do this:
- Power off the chainsaw and wait for it to cool down.
- Remove the side plate and take off the chain from the bar.
- Reverse the chain so that the teeth face forward on the top edge of the bar when reinstalled.
- Follow the same steps mentioned above to reinstall the chain properly.
Make sure to wear gloves during this process to protect your hands from the sharp teeth.
Maintaining Your Chainsaw Chain
To keep your chainsaw in optimal condition, regular maintenance is necessary:
- Regularly clean the chain and bar to remove sawdust and debris.
- Sharpen the cutters when they become dull. A sharp chain is not only more efficient but also safer to use.
- Check and adjust the tension of the chain frequently, as a loose or overly tight chain can be dangerous.
- Lubricate the chain to reduce friction and prevent wear.
