Saw band running-in

To ensure a full service life of the saw bands, we strongly recommend that you carry out
the „RUN-IN" process.
Running in: Cut the material with the frame lowering reduced to 50% only. When
vibrations occurs increase or decrease the band speed.
When cutting small pieces run the band until approximately 300 cm2 of material has
been cut. When cutting large pieces run the band for 15 minutes approximately. When
the band has been run, increase the lowering-speed to normal speed.
The running in of the saw band avoids micro-breaks on the cutting edges of new saw
band ensuing from first excessive stress. This would decrease service life substantially.
The optimal running in of the saw band produces ideal rounded cutting edges and
therefore the conditions for an optimal service life.
