How to Install a Chainsaw Chain: A Comprehensive Guide39

Installing a chainsaw chain correctly is crucial for ensuring the smooth and safe operation of your chainsaw. An improperly installed chain can cause damage to the chainsaw or, worse, lead to accidents. This guide will provide you with step-by-step instructions on how to install a chainsaw chain.

Step 1: Safety Precautions

Before you begin, take the necessary safety precautions to avoid injury:* Wear appropriate safety gear, including eye protection, gloves, and hearing protection.
* Ensure the chainsaw is turned off and unplugged.
* Place the chainsaw on a stable surface to prevent it from moving while you work.

Step 2: Remove the Old Chain

If there is an old chain on the chainsaw, you need to remove it first:* Loosen the chain tensioner by turning the adjustment screw counterclockwise.
* Remove the side cover of the chainsaw to access the chain and bar sprocket.
* Lift the chain off the bar sprocket and pull the chain out towards the front of the chainsaw.

Step 3: Clean the Guide Bar

Once the old chain is removed, clean the guide bar using a brush to remove any sawdust or debris. This will help ensure the new chain fits properly.

Step 4: Orient the Chain Correctly

The cutting teeth of the chainsaw chain are designed to cut in one direction only. Make sure the chain is oriented correctly before installing it on the bar:* Hold the chain so that the cutting teeth are facing outward from the bar.
* The depth gauge, which is the small ridge on the top of each cutting tooth, should be facing downward.

Step 5: Position the Chain on the Bar

Starting at the front of the bar, place the chain over the bar sprocket and feed it onto the guide bar. Ensure the chain is seated correctly on the bar.

Step 6: Install the Chain Tensioner

Once the chain is on the bar, install the chain tensioner by sliding it onto the bar.

Step 7: Adjust the Chain Tension

The chainsaw chain should be properly tensioned to ensure smooth and efficient cutting:* Turn the chain tensioner adjustment screw clockwise until the chain tensioner is snug against the bar.
* Lift the middle of the chain and it should have approximately 1/16 to 1/8 inch of play.
* If the chain is too tight, it will cause excessive wear on the bar and chain. if the chain is too loose, it could come off the bar during operation.

Step 8: Tighten the Side Cover

Replace the side cover of the chainsaw and tighten the bolts securely.

Step 9: Check the Chain Tension Again

As the chainsaw chain is new, it will stretch after a short period of use. Re-check the chain tension after running the chainsaw for a few minutes and adjust it if necessary.

Conclusion

Following these steps will help you install a chainsaw chain correctly and ensure your chainsaw operates safely and efficiently. If you encounter any difficulties or are uncomfortable performing this task, do not hesitate to consult your chainsaw manufacturer or a qualified mechanic.
