Chain loose on your chainsaw?

Hi there,

Chainsaw bars get loose all the time. This can create a dangerous situation.

Tightening the chain is done through the positioning of the bar. The further away from the drive gear it extends, the tighter the chain is.

The are usually two nuts holding the bar on. These need to be loosened slightly to allow the bar movement.

Depending on your model there may be a guard over them. Remove it.

Once the nuts are loose, locate the tensioning screw. It will be relatively small, located adjacent to and facing parallel to the bar.

This screw is attached to a metal lip that in turn is attached to the bar. The screw remains in one place while the lip moves up down.

Start spinning. Keep going until the chain is tight.

Tighten the Bar Nuts, replace the guard if necessary.

Now go slice some wood.

Best regards
Mike

how do you loosen the chain on a chainsaw husqvarna 136?


Hi there. On the outer bar cover near the motor you will find 2 nuts. Slightly loosen those two nuts. Then check around the these nuts or near where the bar attaches to the powerrhead at the front of the saw. You should find an adjustment screw of some sort, which will be the chain tensioning screw (which moves the bar forward/back depending on which way it is turned). This has the effect of either tightening or loosening the chain, so turn this screw noting whether the chain is tightening or becoming loose.

You must slightly undo those 2 main nuts on the side of the chain/bar cover first or the bar will not move and the chain cannot be loosened.

i am having a problem with the chain on my poulan chainsaw. the chain comes loose or comes off after just a few cuts. am i missing something or could it be a malfunction


It sounds like the chain is not being set quite tight enough. Turn the tightening screw until the chain barely lifts above the bar when pulling on the middle of the chain.

My first chainsaw...am seeking general advice on product use etc


Ok to get correct tension on chain, basically loosen it a little until the chain on the underside of the bar is hanging a little... Now start tightening it up again. Basically you want the chain (the main part of each link) to be just touching the the underside of the bar. This will give correct tension... Note that chain does expand as it heats up so it may loose tension... so this is perhaps best done when the saw and chain has warmed a little. Also, new chain will stretch a little naturally so check tension each tme you use the saw.

If you do not know hoe to sharpen a chain properly, it is best to get someone else to sharpen it, or buy a new chain... Eventually all chains will need to be replaced because they can only be sharpened so many times before the cutting teeth become too small to work effectively or safely.

As for oil, if it is an electric chain saw, you only need chain/bar oil. Any good name branded bar/chain oil designed for chainsaws will work well.

Please rate my solution on FixYa!
Thanks.
