Chain stops when contact is made with tree...

or a to thick chain or the chain was not cleaned after use before a long time The chain may be stiff with tree resin, you have the chain anyway can rotate by hand when the machine is not on the safety brake

Hi Pam:
Using chain saws takes a bit of getting used to, and it can be DANGEROUS.
- The chain must be sharp to be able to cut properly, and a sharp chain "bites" into the wood.
- Before you touch the chain into the wood, you have to speed up the engine. This takes some getting used to.
- Try this technique: With the chain about an inch above where you want to cut, squeeze the throttle about half way so the chain is spinning. Touch the chain to the wood and increase the engine speed as the chain starts to cut. The harder you cut, the more power you need to apply.
After a while it gets to be second nature.
Work Safe, and get an experienced friend to help with some "hands on" coaching.
Cheers.

It sounds like the chain does want sharpening, it depends on what you are cutting ( type of timber, dirty timber,burnt timber etc ) as to how long before it needs sharpening, if the chain comes into contact with the ground below the tree it will lose its edge instantly.

In front of the handle on top of the saw is a hand guard. If in the course of cutting wood you hit it or pushed it forward, it will lock up the chain drive system. It should pull back towards the handle until it again clicks to release the chain. It's designed to lock up the chain drive and stop the chain when the saw kicks back.

Your problem statement seems to be chopped off, but apparently, when you go to cut something, the chain just stops turning. Assuming that is so, remove the bar and chain, then wash out the interior of the clutch mechanism with spray carburetor cleaner. Let dry and re-assemble the bar and chain. Make sure the chain is being properly oiled by running the saw at speed with bar tip near some cardboard--it should leave thin line of oil after several moments. Make sure the chain teeth cut toward you on the bottom run of chain. Hope this helps!

First be sure the chain is on going in the right direction. When looking at the bottom of the bar the sharp tooth should be going towards the motor. When you put chain back on are the chain teeth properly engaged in the sprocket on the motor. Remove the cover again, check that teeth are in sprocket. Make sure pin from adjuster screw is engaged in the hole in the bar. Before you tighten the cover bolts, make sure chain will turn by hand. If not adjust the adjusting screw. Once adjusted, tighten cover bolts. Check again after tightening bar.

It may sound oversimplified but....is your chain sharp? Is the chain on backwards?

When cutting you should be getting nice big chips from the cut. If you are getting more "dust" than chips the chain is dull and needs to be resharpened.

There is no set "time" to sharpen a chain,but you will only get a few hours of cutting before the chain dulls. In soft wood like pine you can go longer. In hardwood like oak or locust you may get an hours worth of cutting. If the bar digs into the ground or hits a rock it's time to sharpen right then because the chain will be dull.

I always carry an extra chain or two just for emergencies like hitting a rock or some wire in a tree.

Remove the cover on the chain side of the saw and loosen the bar and slide it out to take out the chain slack. leave a little slack to allow for free movement.

Good luck and be careful.

If your saw has a removable sprocket, Check the drive sprocket on the clutch drum. Either the the spline is worn or the drive link on the chain is not properly seated in the sprocket well.

if you have the and guard pulled back then it will stall.or if the chain is to tight it will do the same.
