The inclination of the roller is usually adjusted with a handwheel on the back of the bandsaw.

Loosen the lock nut on the handwheel so that you can adjust the inclination. To adjust the run of the band saw blade, turn the upper roller slowly with one hand. The saw blade should run as centrally as possible on the roller. If the saw blade tends to run backwards, the roller must be tilted slightly forwards (B). If the band runs forward and threatens to jump off the roller, the upper roller must be tilted backwards (A). If the band saw blade runs centrally on the roller even after several revolutions, you can fix the setting on the handwheel with the lock nut.

                                                     The saw blade is aligned by tilting the upper roller.
