How to Prevent Chainsaw Chains from Stretching Excessively


Understanding Your Chainsaw Chain

Chainsaws are handy tools that make outdoor tasks much more manageable. With its sharp teeth and rotating chain, you can cut wood and logs with ease. However, just like any other tool, chainsaws require proper maintenance to operate at their best.

One of the most significant issues you might encounter is excessive stretching of the chainsaw chain. In this blog post, we’ll discuss ways on how to prevent chainsaw chains from stretching excessively. Let’s begin by understanding the components and how chainsaw chains work.

Components Of A Chainsaw Chain

Each chainsaw chain has three crucial parts: the cutters, the tie straps, and the drive links.

  • Cutters refer to the blade’s sharp edge, responsible for slicing through wood.
  • The tie straps hold the cutters’ position through their hooks and holes and keep them in place.
  • The drive links are found between the tie strap and cutter, connecting the chain to the chainsaw guide bar’s sprocket.

How The Chainsaw Chain Works

The chainsaw chain is a system made up of sharp teeth that rotate around the chainsaw’s guide bar. This rotation is caused by the chainsaw engine’s power, which drives the chainsaw’s sprocket to rotate, which then causes the chain to move.

Here are the steps involved in how the chainsaw chain works:

  • The chainsaw is turned on, and the engine creates energy.
  • The engine’s energy is transmitted through the clutch, to the sprocket at the chainsaw’s end.
  • The rotating sprocket causes the chainsaw chain to rotate.
  • The chain’s cutters come into contract with the wood, cutting and removing its fibers.
  • The chain’s cutters rotate back to their initial position, and the chain continues to loop around the guide bar.

Therefore, maintaining each component of your chainsaw’s chain is essential in ensuring it doesn’t stretch excessively. By doing so, you can keep your chainsaw functioning efficiently and, most importantly, safely.

Common Causes Of Chainsaw Chain Stretching

Chainsaw chains that excessively stretch can be a nuisance, especially when it comes to smoothly running the machine. The common causes of chainsaw chain stretching include high load conditions, dull chain or improper sharpening techniques, use of low-quality chainsaw chains, and incorrect tensioning of the chainsaw chain.

High Load Conditions

Chainsaw chains can stretch excessively due to high load conditions while cutting. Some of the reasons that might lead to such conditions include:

  • Cutting through very hard materials such as thick tree trunks and branches.
  • Continuing to use the chainsaw while the chain is dull or improperly sharpened.
  • Applying too much pressure while cutting, which puts excessive strain on the chain.

Dull Chain Or Improper Sharpening Techniques

A dull chainsaw chain can cause excessive stretching because the chain teeth won’t properly grip the wood. This will cause the chain to slip and deteriorate over time. Some of the reasons why your chainsaw chain might become dull include:

  • Continuously cutting through dirt or rocks, which dulls the chain’s teeth much faster.
  • Not properly sharpening the chainsaw chain. This includes using the incorrect file size for the chain, filing the chain’s depth gauge too low or too high, and grinding the top plate angle too far back or forward.

Use Of Low-Quality Chainsaw Chains

Using low-quality chainsaw chains can also cause excessive stretching. Cheap, poorly made chains often use brittle metals that cannot withstand the cutting force or friction generated by the saw’s motor. This results in the chain becoming loose, slipping, or even breaking.

Investing in a high-quality chainsaw chain can help prevent such instances.

Incorrect Tensioning Of Chainsaw Chain

If the chainsaw chain is too loose, it can cause excessive stretching, which can lead to the chain coming off the guide bar or causing damage to the machine. If the chainsaw chain is too tight, it will cause undue stress, leading to the chain stretching over time.

It’s essential to correctly tension the chainsaw chain by adjusting the chain tensioning screw that is located on the side of the chainsaw body.

Preventing chainsaw chains from stretching excessively can prolong the life of your chainsaw, save you time and money, and help avoid accidents while in use. Ensure to check the chain’s tension regularly, sharpen and maintain the chain correctly, avoid high load conditions, and use only high-quality chainsaw chains.
