How to properly tension the chain on an electric and gasoline saw?

I greet the guests and regular readers of the channel. Today we will learn how to properly tension the chain on an electric or gasoline saw. I have an electric saw, I use it for almost the entire summer season and I was sure that I knew thoroughly how to properly tension the chain. But after this instruction, I realized that I was not pulling the chain quite correctly.

I decided to make an instruction on the channel, because I am 100% sure that I am not the only one and many make mistakes when they stretch out of ignorance.

Let's get to work and start with a gasoline saw. From the beginning everything is as always. We put the tire in its place and move it point-blank to the sprocket, then install the chain.

After installing the chain, take the bar and move it away from the saw body to the maximum, creating a preliminary tension.

Now we put the cover on the case. In this model, the tension adjustment pin is located in the cover.

I will not tell you how to install the cover, everyone should know this. In our case, the pin should go into the lower hole on the saw bar, and just below (marked with a red arrow) is the oil supply hole for the chain. We check that it is clean.

Now we tighten the nuts that secure the cover and the tire. First we twist it all the way, and then we twist it half a turn to give a little slack to the tire.

Now we take a flat screwdriver and pick up the slack clockwise.

That's it, they chose the slack. At this stage, many stop and believe that the chain tension is over, but this is far from the case.

Next, we put the saw on the end, with the tire up. With both hands, we take the chain and begin to roll it back and forth. This is necessary to straighten the chain as much as possible, especially if it is dirty. If the chain is new, then this can be omitted.

After such manipulations, we will see that we again have a slight slack and when we pull back the chain, then 5-7 teeth completely come out of the groove. And under normal tension, only three should come out of the groove.

We take this slack again by tension.

Each saw has a specified up and down bar play. When the saw is on the table, the bar is lowered down under its own weight, but when we start sawing, the bar rises slightly and sag is formed again.

Now we lift the bar up with our hand so that the saw is in a semi-hanging position and again we take out the slack, only without fanaticism.

Next, we continue to hold the saw by the tire and in this position we clamp the nuts on the cover. This completes the first stretch stage.

On an electric saw, we do the same procedure, only with small nuances. In this model, the tension pin is located in the saw body, indicated by the white arrow.

We put on the tire in place. In our case, we have two holes on the bus. One of them serves to fix the tire itself, the second (marked with a red arrow) serves to lubricate the chain. Oil enters this hole and goes through a special channel to the chain. When assembling, check that the channel is not clogged, if necessary, clean it.

The electric saw does not allow the tension to be distributed along the chain like on a denzopil, so we select the belly, then we turn the chain manually towards the body. If there is a slack, then it is picked again.

Further down the list, we lift the saw by the edge of the tire, again select the chain slack and in this position tighten the nut on the cover.

We make a test cut.

After cutting, if the chain is not new and was dirty, then most likely the slack will reappear. Let the chains cool down a bit after cutting and again select the resulting slack.

How can I check the correct tension of the chain. In the photo you can see, we take a screwdriver, rest it on the tooth and push it away from ourselves, imitating sharpening a pencil. In this case, the chain should go easily, and after you have stopped pushing, the chain will pass a little more by inertia. If the chain is overtightened, it will stop as soon as you stop making efforts.

That's all love comrades. You have learned how to properly tension the chain.

Thank you all for your attention, for the likes and subscription to the channel. Mikhalych was with you, I wish my subscribers peace and good. See you soon in a new homemade product.
