what makes a chane lock up on poulan chane saw 2150 2.1 c.i?

Answer 1

Sometimes, When the chainsaw's bar (part that the chain travels around) gets worn excessively, usually due to improper or not enough lubrication, the metal from the chain can grind and bite down into the metal of the bar, causing so much friction that the saw's engine is unable to move the chain, This result is also a common result of wood debris clogging up the area where the drive gear contacts the chain, or it could be the result of an overtightened chain. Oftentimes, while in this situation, the user will push the mechanical limitations of the small engine, causing it to run very hot, further robbing horsepower, and helping friction to further slow the chain.

Answer 2

You may have fod between the chain and the gear. Rotate it backwards by hand with the spark plug wire removed and see if it frees it up. If the chain is too loose it could have tried to jump off of the gear. Rotating it backwards may also relieve this but you will need to tighten it up. If it is rusted, oil it and work the chain back and forth. If none of this works I would take it into a shop or see if any of your friends can look at it. make sure they know what they are doing.

Answer 3

make sure the safety brake isn't engaged, the sprocket could have dried up and frozen you could have pinched the bar and now it will not allow the chain to pass around it. take the saw apart and clean really good and look for any little thing that could hinder the movement of the chain. good luck and be safe.

Answer 4

The chain being too tight can cuase it to bind,also not getting oiled properly.Make sure the oiler is not clogged with sawdust and that there is oil in the oil tank.
