How To Measure A Chainsaw Bar

Chainsaw bars can be extremely durable and can last for a number of years. If you are suddenly struggling to use your saw efficiently, it’s worth checking that the machine has enough oil inside of it and that the chain on your saw is not blunt, as this could be the cause of the problem.

However, if this is not the case and there is a significant amount of wear or damage to the chainsaw bar, it is best to replace the part. Measuring is crucial in determining the correct size as this will ensure you find the right chainsaw bar replacement.

Measuring Your Chainsaw Bar

Many arborists make the mistake of presuming that their chainsaw bar length is the same as the tool cutting length. However, this isn’t the case. In fact, it takes much more than a tape measure to measure your chainsaw bar correctly. These are the steps to follow:

Step 1

Turn off the chainsaw and unplug its spark plug. You can easily access the spark plug by taking out the carburettor box located at the rear side of your chainsaw. Doing this ensures that your chainsaw doesn’t accidentally turn on while you are taking the measurements.

Step 2

Align the tape measure tip with the chainsaw edge at the point where its bar emerges. Steady the chainsaw by laying it across a flat surface. This makes it easier to quickly extend the tape measure and take an accurate measurement.

Step 3

Pull your tape measure tightly so that it is properly aligned with the farthest tooth of your chainsaw’s nose. Note down the length and then round it up to its closest whole inch. In most instances, this figure will lie in the 12” to 20” range. If you’re not sure of the measurement, make it a point to repeat the exercise a few times. Keep in mind that this is the actual cutting length of your bar and not its entire length. You would need just to use this figure to replace your bar or chain.

Step 4

Remove the metal/plastic casing. You can do this by using the right socket or wrench. Once this casing has been removed, the covered section of the bar would be revealed and you can measure it. This would be the entire bar measurement.

Step 5

And finally, simply reattach the casing as well as the spark plug just as it was before.

Some Things To Keep In View

Power tools like chainsaws can become a liability and be unsafe to use if they aren’t maintained well. Similarly, it is never a good idea to either repair or work on your chainsaw without the proper knowledge.

In addition, always wear safety gear such as eye protection, high-quality chainsaw chaps, gloves etc. to make sure that you are well-protected. If you aren’t very confident about measuring your chainsaw bar, get help from a professional. It is important to use the right type and size of chainsaw based on the model and make of your chainsaw.
