Problem with chainsaw question?

the chain is probably not filed properly. make sure both sides of teeth are filed at same angle and are of even length. make sure the rakers are even as well. the other thing to check is the bar groove make sure to clean it out get all of the fine sawdust out of there. put the chain back on the bar and go to the middle of the bar and see if the chain has side to side movement. if it seems like it wants to roll over it will"butter bowl" if the bar is whipped replace it if it's not that bad there is a tool that you can get from bailey's in oregon that rolls the bar edges back together, the last thing is to mahe sure the top and bottom of the bar rails are flat and smooth. dont use your finger to check it it will cut you for sure. you can use a flat file to smooth it but bailey's also have a tool for that as well. another source for these tools is ahlborn equipment, but you need a dba tobuy stuff from them

your chain may be a little loose so that when you get half way through you start adding more pressure and it tilts the bar. try adjusting the tension on your chain and let the saw do the work, don't apply too much pressure and roll the logs so you only need to cut 1/2 to 2/3 the way through. that will also help keep you from putting the chain into the dirt and save the life of the chain's blades.

nothing, your bar has a left side and a right side one side has more wear than the other so you need to use a flat file and straighten the glide up , use a combo square and you will see the unevenness, you can go on line to Baileys .com and they have everything a wood cutter could ask for and they ship for free.

The blade has been sharpened to many times and the teeth on one side of the blade bite into the wood more than the other side . that will make the blade travel out of line.
