How to Tighten a Chainsaw Chain

If you already know how to clean your chainsaw, it would be suitable to understand how to tighten it up to make it work like a gem.

No matter the way you use it, the right maintenance & preparation of this tool will be crucial to how well it performs when using it.

But tightening this tool is not as easy as it seems. There are a few things you should know before doing it if you want to avoid problems and make it work correctly. So, if you are eager to learn how to tighten it up – then come further and read up!

Things You Need

Tightening a chainsaw is not as straightforward as pulling a lever or touching a button. You will need several other tools to do it. These tools are:

  • Flat Screwdriver
  • Die Key for security screws
  • Security Gloves
  • Cloth or towel for cleaning
  • Clutch tool for adjustment, preferably a factory-made one
  • The user manual of the chainsaw (if possible)
  • An additional person to help with the tightening (if possible)

Before explaining the tightening step you must know about what good tension and bad tension looks like. Here you go!

How to Tighten a Chainsaw Chain

Here are a few steps you need to make divided into three sections: Demounting the chain, Tightening the chain, and Mounting the chain. Take a look further to find out more!

Demounting the Chain

  1. To work safe, make sure the chainsaw will not move or start spinning (try to find its spark plug and unplug it).
  2. There is a case on the right side with two security screws, remove it (use the chainsaw’s factory clutch tool, the screwdriver, or a die key).
  3. Now you are going to see two medium-sized steel bars, and one pin above and one below; these pins are securities “to lock” someway the bar and avoid movement. Unlock them.
  4. If you do not see any of them, think about replacing them before using, or it can cause movement. Check them all, and try to move them with your hand.
  5. Remove the chain carefully without harming the cutting teeth
  6. Remove the bar to start with the calibration.
  7. Put everything you removed aside and remember the order and place where they were

Tightening the Chain

This is a slightly harder part than the rest, and you’ll have to be careful here, or else you could damage the chainsaw. However, you can do it well if you follow these steps:

  1. After demounting the bar, you have to look for a screw or pin that works to increase or decrease the tension of the chain. It is usually behind or below the bar.
  2. Look for two steel screws that move if we spin the tightening screw. If any of these screws are out of shape, we have to replace it, or the tension will not work.
  3. You’ll have to know the right tension for the chain. Then, with a screwdriver, tighten the chain accordingly.
  4. Verify the chain’s clutch with the medium-sized steel screw. Also, check the teeth that make the chain move.
  5. After adjusting the tension, put the bar back. Pin it up correctly. You can inverse the way you set the chain to divide the weight.

Mounting the Chain

  1. Put back the chain on the bar, and check if it is tight enough.
  2. Verify if the tension is fitting. Adjust the tension if needed to avoid the chain to whiplash, or tension loss.
  3. Put back the screws’ cover and hold it on while you pin them up with the die key. Do it carefully this time.
  4. With one hand rise a bit the front of the bar, and readjust the tightening of the chain.
  5. Give two more turns on the security screws.
  6. Check the chain’s tension. It is necessary to leave a bit flyaway to adjust chain’s resistance.
  7. Pin up the security screws strongly to add the sturdiness.
  8. Then check the tightening by trying to move the chain with one or two fingers. The chain has to move with no problems, if it does not move, adjust the tightening.
  9. If the chain clutch makes a sound while you move it, it means the tension is the right one. Here, you are already finished and ready to use your chainsaw again.
