Which Way Does the Chain Go on a Chainsaw?

Setting up a chainsaw chain correctly is essential for safe and efficient operation.

If the chain is installed backward, the chainsaw won’t cut properly and can pose serious safety risks.

Whether you’re a beginner or an experienced user, understanding the correct direction for the chain is crucial.

In this article, we’ll explain which way the chain goes on a chainsaw, provide easy-to-follow instructions, and include tips for ensuring your chainsaw operates at its best.


Understanding Chainsaw Chain Direction

The cutting side of a chainsaw chain has sharp teeth that must face the correct direction to cut effectively.

The teeth should always face forward on the top side of the bar.

Key Indicators for Correct Chain Orientation:

  1. Top of the Chain: The sharp edge of the cutter teeth points away from the chainsaw body.
  2. Bottom of the Chain: The sharp edge of the teeth points toward the chainsaw body.
  3. Drive Links: Fit snugly into the guide bar groove to provide proper motion.

Why Does Chain Direction Matter?

Installing the chain incorrectly can lead to:

  • Poor Cutting Performance: A backward chain won’t cut wood.
  • Increased Wear and Tear: Incorrect setup strains the engine and chain components.
  • Safety Risks: A non-functional chainsaw increases the chance of accidents or misuse.

Step-by-Step Guide: Installing a Chainsaw Chain in the Right Direction

Follow these steps to ensure your chainsaw chain is installed correctly:

1. Prepare the Chainsaw

  • Turn off the chainsaw and disconnect the spark plug for safety.
  • Lay the chainsaw on a stable, flat surface.

2. Remove the Chain Cover

  • Use a wrench or tool to remove the nuts or bolts holding the guide bar cover in place.
  • Take off the cover to expose the guide bar and sprocket.

3. Position the Chain on the Guide Bar

  • Place the chain around the sprocket and guide bar, ensuring the cutter teeth face forward on the top side of the bar.
  • Check that the drive links fit securely in the guide bar groove.

4. Tighten the Chain

  • Pull the chain tight along the guide bar to remove any slack.
  • Adjust the tensioning screw until the chain sits snugly on the bar but can still move freely.

5. Reattach the Chain Cover

  • Replace the cover and secure it with the nuts or bolts.
  • Double-check the tension after tightening.

Common Mistakes to Avoid

MistakeConsequence
Installing the chain backwardChainsaw won’t cut properly or at all.
Over-tightening the chainIncreases wear on the chain and guide bar.
Failing to secure the chainRisk of the chain slipping off during operation.
Ignoring chain tensionCan lead to poor performance or damage to parts.

Tips for Maintaining Your Chainsaw Chain

To keep your chainsaw running efficiently:

1. Regular Inspections

  • Check the chain for wear and tear before each use.
  • Look for dull or damaged cutter teeth.

2. Sharpen the Chain

  • Use a file or chainsaw sharpener to keep the teeth sharp.
  • Replace the chain when sharpening no longer improves performance.

3. Lubricate the Chain

  • Ensure the oil reservoir is filled with high-quality bar and chain oil.
  • Check for proper oil flow during operation.

4. Store Properly

  • Clean the chain and guide bar after use.
  • Store in a cool, dry place to prevent rust and corrosion.

FAQs About Chainsaw Chain Direction

1. How do I know if my chain is backward?

If the chain’s cutter teeth are not facing forward on the top side of the guide bar, it is installed backward.

2. Will a backward chain damage my chainsaw?

While it may not directly damage the engine, operating a chainsaw with a backward chain strains the engine and wastes fuel.

3. How often should I check my chain orientation?

Always check the chain direction when installing a new chain or after maintenance.

4. Can I fix a backward chain myself?

Yes, simply remove the chain, flip it to the correct orientation, and reinstall it following the guide above.

5. What tools do I need to install a chainsaw chain?

You’ll typically need a wrench for the chain cover, a tensioning tool, and PPE like gloves for safety.


Conclusion

Knowing which way the chain goes on a chainsaw is essential for both beginners and experienced users.

Correct chain orientation ensures your chainsaw operates safely and efficiently, delivering optimal cutting performance.

By following the steps outlined in this guide and performing regular maintenance, you can avoid common mistakes and keep your chainsaw in top condition.

Always prioritize safety and double-check the chain direction before starting your tool.
