15.4. 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 occur increase or
decrease the band speed.
When cutting small pieces run the band until approximately
300 cm
2
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.
