Setting the saw band guides

The saw band must always be guided between the ball bearings. The lateral distance between
the lateral surface and saw band should be 0.1 mm (see drawing).
It is important to ensure that the saw band teeth run freely and are not damaged by the guides. If
the guide clearance between ball bearing guide and saw band be incorrect proceed as follows.
 If you have not already done so, execute the steps in Chap. 9. aus.
 If necessary remove saw band covers.
 Loosen the screws of the bearing pins.
 Insert the saw band correctly and insert between saw blade and lateral surface of the ball
bearing a feeler gauge strip with 0.1 mm thickness.
 Retighten the nuts of both bearing pins by observing the distance.
 Check manually whether the saw band now runs properly.
 Mount and close all saw band covers an check saw band tensioning before turning on the
machine for additional testing.
If saw band ist running out of upper saw band guide set it as follows:
 If you have not already done so, execute the steps in Chap. 9. aus.
 Incline the holder of the band guide to the rear, as shown in detail C.
 Loosen therefore screws 1 and screws 2.
 Incline by screwing the screws 2 the holder of the band guide slightly This makes the saw
band runs towards the rear guide. The saw band is thus no longer runs out of the saw band
guide.
 Check if the setting is correct by moving the saw band by hand.
 If saw band runs correctly, check the adjustment over the whole adjustment range of the up-
per band guide arm.
 Mount and close all saw band covers an check saw band tensioning before turning on the
