Loosen and remove the nuts securing the chainsaw’s side cover using an appropriately sized wrench.
Carefully remove the side cover to expose the chain and bar.
Relieve the tension on the chain by turning the tension adjustment screw or knob in a counterclockwise direction.
Now, gently remove the chain from the bar, starting at the top and working your way down, cautiously sliding it off the sprocket.

Ensuring Proper Handling

Inspect the chain for signs of wear and damage.
Clean any dirt or sawdust from the chain.
Lay out the chain on a flat surface for inspection and measurements.
Handle with care, ideally wearing gloves, to avoid injury from sharp edges.

Measuring and Marking

Before shortening your chainsaw chain, precise measuring and marking are crucial to maintain the saw’s balance and effectiveness. Use a tape measure or ruler to determine the desired chain length, marking links for removal to achieve optimal performance.

Identifying the Correct Length

Consulting your chainsaw’s user manual to find out the bar length, pitch, gauge, and number of drive links the chain should have.
Inspecting your current chain to confirm the actual count of drive links.
Equating the recommended specifications with the current chain’s measurements to identify any discrepancies.
Deciding on the number of links that need removal to achieve the correct length.

Marking the Chain For Cutting

Once you’ve identified the correct length, marking the chain accurately is vital. Begin by:

Cleaning the chain thoroughly to improve visibility of the links.
Securing the chain in a stable position, ensuring it won’t shift during the marking process.
Using a permanent marker or a metal punch, pinpoint the exact link that aligns with the length you need.

Shortening the Chainsaw Chain

Shortening a chainsaw chain ensures optimal cutting performance. This process involves detaching, sizing, and refastening links, requiring precise tools and safety precautions.

Using the Right Cutting Technique

Stabilize the chain on a solid surface to prevent it from moving during the procedure.
Identify the link where you’ll shorten the chain. This should align with the desired chain length for your saw.
Use the chain breaker to push the rivet out of the link carefully. Apply steady pressure to avoid damaging adjacent links.
Remove the unwanted links, ensuring that the remaining chain is symmetrical and the drive links are intact.

Ensuring Precision

Count the links carefully before removal to ensure you’re maintaining the proper chain size for your bar.
Inspect each link after removal to ensure no damage has occurred during the process.
Reattach the chain using a spinner, aligning the rivets correctly and clamping them securely.
Test the modified chain for proper movement and tension.
