However, if the blade does not require sharpening and you maintain your machine very well, then it is likely that the chainsaw bar will need replacing. If you are unsure whether your bar needs to be replaced, see below the following checks you can do see if your chainsaw bar needs to be replaced or not.

Checking your Chainsaw Bar

Firstly, check to see if the bar is crooked. To do so, hold the bar up and look at it in the same manner you would to check a piece of wood. If you notice that the chainsaw bar is crooked, then this is a sure sign that the chainsaw bar needs to be replaced.

Before you replace your chainsaw bar, make sure you have enough oil, as this is one reason why the sprocket will stop working.

Lastly, if your bar has chunks or dinks on it, then this is another serious sign that your chainsaw bar will need replacing as soon as possible.McCulloch Petrol Chainsaw

How to maintain your chainsaw bar

Once you have replaced your chainsaw bar, you are probably not going to want to have to do that for again for a while, as in doing so will set you back a bit financially.


The first method to maintaining your bar is to lubricate the small hole near the end. By doing so, this will make the sprocket rotate easily and will make it last longer. Just a couple of squirts of grease should do the trick.


You should also clean the groove at the edge of the bar. It is important to do this on a regular basis as it can easily get clogged with sawdust and dirt which can soak-up any oil, making the bar and chain ware-out prematurely. To clean this groove, all you need is a small, thin object such as toothpick or screwdriver; or alternatively you can use compressed air as you would on your computer.
