Chainsaw mill problem!

[steforfan]

My problem is that the saw bar starts being pushed upwards after about three decimeters of cutting. The bench is straight and level. The chains are new and of the right type. The logs are fairly knot-free and moderately thick.
Is there anyone who has experienced something similar and managed to solve it, and can share their story, then Stefan will be happy forever.

Hi
Are they misspelled?
Is it possible that you hit a nail, knot, etc. that made the blades dull on one side?

Do you saw for long? I usually turn after each cut as longer logs tend to sag into a banana shape.

Uneven wear on the bar?

Is the sword "horizontal"?

Hello

No. They are brand new chains and different logs

Hi
Then it feels like the sword angle is not parallel with the path.
Dirt in the attachment or something that creates an angle grinder.
