Removing The Saw Band - Rothenberger BS 450 Instructions D'utilisation

How to tension the saw band:
Information
• Since the length of the saw band varies due to manufacturing tolerances and tem-
perature fluctuations, you must find the optimal tension for the saw band while work-
ing with the machine.
• The saw band is optimally tensioned when the marking line on the guide of the ten-
sion wheel with the MAX mark agrees (marking laterally on saw bow.
 If you have not already done so, execute the steps in Chap. 9. aus.
 If the saw band tension is too weak (bad saw cut quality, saw band jumps off of the diver-
sion-wheels etc.), turn star grip (D) at diversion wheel (1) clockwise until it is tensioned opti-
mally. Please also refer to the notes in Chap. 8.
 If the saw band tension is too strong (saw band tears), turn the star grip counter-clockwise
until it is tensioned optimally.
