How to tighten chainsaw chain

It is essential to keep your chainsaw chains tightened and sharp for efficient and safe performance. So, the first step in keeping your saw working properly is holding the chain tight. So, here we are going to discuss the complete method of how to tighten chainsaw chain.

Never let the chain get so loose that it slips off the bar while cutting or idling along at high speeds. You can tell when a chain is too loose because it will start to flop around and jump off the bar. On the other hand, chains that are too tight will be hard to start and very sluggish while running and can also cause dangerous kickbacks.

Tightening chains is an essential part of saw maintenance, It does not matter that you are using electric chainsaw or 4 stroke chainsaw or any other type, you need to tighten the chain. Make sure to check your chain once a week or after every couple hours of use.

How to tighten chainsaw chain

Before you start tightening your chain, be sure the engine has cooled off. Trying to tighten a saw with hot metal will burn you.

Before you have a chance to tighten your chainsaw chain, you will need to collect some necessary items so that the task is as easy as possible for you. 

Here are some of the things you’ll need: – Flathead screwdriver – Phillips head screwdriver – Socket wrench with drivers in both sizes – Torque wrench – New chain.

Tight the Chain Bar

To get started, you need to inspect the situation. If you can see that there is a play between the bar and blade, then it is pretty easy to tighten it again with some simple tools. You can tighten the bar in three different ways. Let’s get started to explore them.

Screwdriver tightening method

If your saw is vibrating or running very loudly, the problem is most likely with the screws holding the bar to the saw.

Take a look at the bar closely, and you’ll see two screws on one side and often just one on the other. The ones that are loose will be easy to spot as they will come out very far from the body of the bar. What you need to do is tighten these with a screwdriver. So that it no longer comes loose and stays in place while you use your chainsaw.

To do this, counter-tighten the screws with a screwdriver until they are snug and then turn them back half a turn to get an even tighter grip. It will be much more challenging to get out if one is stripped, so you may want to skip that one for now and come back to it when you have the time.

Socket wrench tightening method

It is a much more secure way of keeping the bar in place, but it does require that your chain saw has screws on both sides. If not, this method will still work, but you’ll have to tighten one at a time instead of being able to do them both at once.

The screws you need to tighten are located on the top and bottom of your chainsaw bar. You will want to remove it from the saw, place it on a flat surface so that the blade is facing up, and use a socket wrench to tighten them. While you do this, pay attention to how tight they have become, ensuring they aren’t too tight to avoid future damage.

Using a torque wrench for tightening chainsaw 

It is by far the most secure way of keeping it in place, but you will need a torque wrench to get the job done.

The problem is that not every homeowner has one of these handy, so it may be an option for you if your saw is already damaged or you have no other options, but it’s definitely worth trying out the other two methods first to see if they work for you!

You just need to tighten or loosen the screws with any tightening tool like screwdriver or wrench. Tight it based on how loose or sharp you would like it to be. Must turn it clockwise to tighten the chain and anti-clockwise for loosening it. You can proceed with doing this until it fits properly around the guide bar.
