Drive Link CountThe total number of drive links the chain possesses

Match these specifications with those recommended in the manual to ensure a perfect result.

Safety Precautions Before Installing the Chain

Prioritizing safety cannot be overstated. Protect yourself and your surroundings by following these steps:

  1. Wear protective gear: Always use safety glasses, durable gloves, and other protective clothing.
  2. Tool inspection: Make sure your chainsaw is off, and the spark plug is disconnected to prevent accidental starts.
  3. Stable work environment: Secure the chainsaw on a sturdy surface to prevent movement during the chain installation.
  4. Examine existing equipment: Check the guide bar and sprocket for wear and damage.
  5. Ensure proper lighting: Work in a well-lit area to clearly see what you are doing.

After taking these precautions, you are now ready to install the chain correctly onto your chainsaw.

Step-by-step Guide To Proper Chain Installation

Ensuring your chainsaw chain is installed correctly is vital for optimal performance and safety. This guide will take you through the essential steps of fitting your chainsaw chain properly. Paying attention to detail during installation prevents mishaps and maintains the effectiveness of your tool. Each step below will help guarantee your chainsaw runs smoothly and safely.

Loosening the Tension and Removing the Guide Bar

Begin by loosening the chain tension. This is crucial as it allows for the easy removal of the guide bar and old chain.

  • Locate the tensioning screw near the guide bar on your chainsaw.
  • Turn the screw counterclockwise to loosen the chain tension.
  • Once loose, carefully remove the guide bar and chain from the chainsaw.

Positioning the Chain on the Sprocket and Guide Bar

Next, ensure the new chain fits onto the sprocket, then onto the guide bar.

  1. Place the chain over the sprocket, aligning it properly.
  2. Thread the chain along the guide bar, making sure it sits snugly in the bar groove.
  3. Adjust until the chain’s drive links engage with the sprocket teeth.

Ensuring Proper Chain Direction and Tension Adjustment

The chain must face the correct direction for the saw to cut effectively.

  • Confirm the cutting teeth are facing forward on top of the guide bar.
  • Reattach the guide bar to the chainsaw.
  • With the guide bar in place, lightly tighten the tensioning screw.
  • Verify there’s no sagging on the underside of the guide bar.
  • The chain should still be able to move freely around the bar without binding.

Securing the Guide Bar and Final Chain Tension Check

Once the chain is positioned and tensioned properly, secure the guide bar.

  1. Reinstall any plates or nuts that were removed during the guide bar removal.
  2. Tighten these components firmly, but do not fully tighten yet.
  3. Perform a final chain tension check. Lift the chain lightly and release. A properly tensioned chain will snap back into place.
  4. If satisfied with the tension, fully tighten the nuts to secure the guide bar.

By following this detailed guide, your chainsaw’s chain will be installed correctly, ensuring top efficiency and safety during operation.

Verifying Correct Chain Installation

Installing your chainsaw chain correctly is crucial for both optimal performance and safety. An improperly installed chain can lead to inefficient cuts, a higher risk of accidents, and even damage to the chainsaw itself. Let’s dive into the steps to ensure your chainsaw chain is on the right path.

Visual Inspection Of Chain Direction

Always start with a visual check. The chain should have its cutting teeth pointing forward on the top of the bar when the chainsaw is in operation. It’s straightforward: look for the sharp edges or the angled teeth. They need to face away from the chainsaw body on the upper side of the bar and towards the body on the underside. This orientation is vital for effective cutting.

Manual Testing For Smooth Rotation

Following the visual confirmation, move on to manual testing. With gloves on and the chainsaw switched off, grasp the chain and rotate it along the bar. The movement should be smooth, with no snagging or stiffness. If the chain binds or is too loose, it requires adjustment. This step is essential to prevent a stationary chain during operation, which can be a clear sign of incorrect installation.

Checking For Proper Tension and Alignment

A correctly installed chain showcases optimal tension and alignment. To test the tension, pull the chain slightly away from the bar; it should snap right back into place. A loose chain could disengage completely, while an overly tight one risks breakage. Additionally, check that the chain sits squarely on the bar without any sideways tilt, ensuring that the drive links fit perfectly into the bar groove.

Conducting a Test Cut and Observing Performance Indicators

The final step is a practical performance test. Make a test cut on a piece of wood; it should go through smoothly without undue pressure. Also, observe other performance indicators. These include the production of fine sawdust (as opposed to large chips or erratic sawdust patterns), consistent cutting sound, and a lack of burning smell or dark marks on the wood, all of which can signal that the chain is correctly installed and tensioned.


Ensuring your chainsaw chain is properly mounted safeguards both your efficiency and safety during operation. Regularly check for correct tension, alignment, and sharpness. Remember, a well-maintained chainsaw is key to smooth, effortless cutting. Keep these tips in mind, and you’ll tackle your cutting tasks with confidence.
