Look the chain saw over, and clean any debris or stuck pieces of wood from all areas surrounding the chain. Grab the chain, and ensure that it turns on the chain saw bar. If after freeing up the pull-cord or replacing it, you find it operational, this also means the piston is moving freely inside the chain saw engine.
One of the most common problems that chainsaw users often face is when their chainsaw seizes. A seized chainsaw should be quite the problem for chainsaw users, especially when they are in the middle of an actual job. A chainsaw can seize up when the carburetor was set too lean or whenever it isn’t functioning properly.
If the pistons of your engine are jammed in their cylinders or the crankshaft is bent, it’s a sign of engine seizure and as a result, your chainsaw would be locked up. If no compression is recorded at the gauge, then most probably your engine is seized and you should consider investing in a new chainsaw. The sudden throttling up of your engine can raise the temperatures abruptly which can damage the gaskets and rings of your engine.
If Im a Husky dealer, and someone has a saw bought new from me, 7 years ago, and it has around 250 hours on it, and it comes in for a service…A service includes nothing more than chain sharpening or replacing, new plug, new or clean air filter, check top no load rpms, clean it up, new fuel filter, fresh fuel, and send it on its way. If the saw goes home, and a few days later burns up, and it comes back to me…I know its not the plug, nor fuel filter causing a problem, nor the chain…so the problem will be either random mechanical failure, improper fuel mix, or abuse…assuming the fuel line is good to go, and the intake boot is good. A shop cannot be expected to warranty or absorb a 7 year old saw, and assuming they did the tune-up correctly 9hard to get wrong), I dont see any reason, assuming it ran correctly when picked up, that they are at fault.
Fuel especially pump fuel doesn’t last long, looses it’s volatility and ethonal fuel absorbs moisture. I’ve never had saw issues using fuel a few months old or even 6 months old although I try to keep the fuel less than a month, same saw for thirty years. Hill Top no worries about the oil settling out of mixed fuel.
why does a chainsaw locked up Related Question:
What would cause a chainsaw to lock up?
The reason why a chainsaw seizes is that the lack of lubrication on the piston. When the piston got stuck due to lack of lubrication, it seized the chainsaw engine up. In some cases, the same can happen if the chainsaw’s carburetor is too lean or if it was not functioning properly.

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.
