Specifically to loosen the drive cog to give slack to the chain
Experienced gardeners share their insights in answering this question :
Closely look along the sides of the chain and look for a lock key between to links
push the key sideways and then dissemble the link and the chain will come off
Same as a push bike chain link

The general rule of thumb (there are exeptions) is that if a chain achieves a 3% increase in the original length, it`s time to replace the chain. The chain must be measured under tension on the drive or you can also hang the chain with a specified weight suspended on it.
The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm, i.e. the wear limit. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it`s important to keep an eye on.
Replacing your chain regularly can prolong the life of your drivetrain. Most mechanics agree that you should replace your chain about every 2,000 to 3,000 miles, depending on your riding style.
“It can vary between 3,000km to 8,000km generally speaking, but it could be less or even more in some cases.” First, you need to replace your chain when you spot any damage (a deformation or crack). You should also check your chain regularly to see if it has worn to the point that you need to change it.
A chainsaw chain can be sharpened up to 10 times, sometimes more, before the entire chain needs replacing. It`s mostly dependent on two things; the amount of wear your chain incurs and the amount of metal removed every time you sharpen. Different materials can have a harder impact on the chainsaw chain.
Most chainsaw chains will last between 1-5 years. If you use your chainsaw daily and tackle tough jobs, the chain won`t last more than a year. But, if you only use it occasionally and take proper maintenance, the chain might last more than 5 years.
Check gauge for fit between any two roller links. (Do this with chain in tension.) If the gauge step fits through the checkpoint, the chain is worn out and needs to be replaced. (Gauge should be in line, directly below any outside link plate.)

Chain keeps falling off – Poulan 18" Chain Saw Replbar (small Saws)
Your chain is too loose. If you’re using an old chain, you might need to have a link taken out of it. You can find replacement chains for your saw at Hyperparts.com. Use the application lookup link at the top of the page with your model # to make sure you order the right chain.

Take your existing chain to a local chainsaw shop. They will use it as a pattern to make a suitable replacement. Chain size is dependent on the number of drive links not bar or chain diameter. If you don’t have an existing chain take saw and bar. HTH
I have a 107624-02 saw. Motor of saw runs but chain does not move. Trouble shooting diagnosis: Gear train failure. I removed the assembly of the chain bar gear. The “spring steel” strap that is supposed to hold the large gear in apparently lets the gear slip to the outside so the gears do not mesh, and the chain does not move. The gears look OK, so it doesn’t appear they are worn and need replacing.
However, if they need replacing, how does one get the small one out, which may be attached to the motor drive shaft. There are no details in the owner’s manual. In troubleshooting, it simply states “see authorized service center”. I prefer to repair it myself, for which I need details of the gears assembly.

REPLACE THE CABLE
I am having problems with the chain coming off the guide rail of a Husqvarna 345. A new rail and chain was put on the saw recently. When the chain came off last time I noticed a lot of wear on the teeth that sit in the guide rail – in some cases the teeth were almost worn away altogether. The chain is getting oil. What could be causing this – I am wondering if the chain should be tighter.
It is possible that the clutch sprocket teeth are badly worn causing extra wear on the drive teeth of the chain. Remove the bar and chain to check the sprocket–you can determine the wear by comparing the area where the chain runs to the edges of the sprocket that are relatively unworn. If the sprocket requires replacement, the chain should be replaced as well. The chain normally should be loose enough that the chain can be moved by hand, but it should not droop from the lower bar edge. Check the chain oiling by running the bar tip at speed near some cardboard–it should throw off a thin line of oil after a moment or two. There should be an oil volume adjustment screw located on the under side of the case near the chain return area–turn CCW to increase flow. Hope this helps!
My mower blades disengage when operating.
Not sure of your question, but if you mean, they start when you flip the switch and then disengage but the switch stays up.. you need to check two things. (1) The out put of your alternator, read the battery with a volt meter before you start it, then start up the engine and read the voltage again should be a higher reading with the engine running. 12.4 vdc with the engine off – 13.7 vdc with it running. (just an example). Next will be your seat switch.There is a switch under the seat if you are not sitting in the seat the blades should turn off. so the switch could be out of its socket, or broken.
Chain saw chain is loose
Loosen the side cover nuts, then turn the adjuster CW to bring the chain up to the lower edge of the bar, then check to see if the chain will move fairly easily by hand. Tighten the clamp nuts and recheck tension. If chain seems to get loose quickly again, it may not be sharpened correctly causing heat to build in the chain. You should see no reflection of light from the cutting edges if filed correctly and the saw should require very little pressure for it to cut rapidly. Hope this helps!
