However, if the drive belt is too tight, the nut can be turned anti-clockwise. Over-tightening can cause the machine carrier to twist, resulting in belt misalignment and excessive wear. Fig.: Tensioning the drive belt (toothed belt) BSW 76EPRO (BSW 76GLPRO not shown)
14.2 ADJUSTING THE BANDSAW BLADE DANGER! The bandsaw blade is not covered in the cutting area. Risk of injury! The bandsaw blade runs on two band wheels (tensioning wheel 1 and drive wheel 2), which are cast from aluminium and balanced so that they run evenly. Two band guides (one movable blade guide and one fixed band support) ensure that the bandsaw blade remains in the correct position during sawing.
WARNING! Wear protective gloves and safety goggles when working on the bandsaw blade! 14.2.1 Adjusting the band run The base of the tooth of the bandsaw blade must be flush with the outer edge of the tensioning wheel (± 2 mm). Fig.
Page 63
14.2.2 Adjusting the blade guides The fixed blade support and the movable blade guide must be adjusted so that the bandsaw blade runs without recoil. The saw blade should glide quietly and effortlessly through the guides when the band wheels are turned. If this is not the case, the band wheels are probably tilted.

ATTENTION! New bandsaw blades are supplied rolled up and are under great mechanical tension. Unpack carefully to prevent the band from snapping out and causing cuts! It is important to change the bandsaw blade regularly to ensure maximum performance. The use of blunt bands leads to wavy or imprecise cuts, reduces the service life of the bands and increases the risk of band breakage.
Page 72
7. Insert the new band into the guides first. 8. Then place the band on the band wheels and tension the bandsaw blade by turning the T-handle (S) clockwise. Pay attention to the sawing direction! The teeth must always point towards the chip ejection chute (G). Make sure that the band is correctly aligned on the band wheels and in the guides.
16.2 REPLACING THE DRIVE BELT Regularly check the condition of the drive belt (c). Replace any worn and damaged parts. Also regularly check the tension of the drive belt and adjust it if necessary. To remove the drive belt, first remove the bandsaw blade. See also...
16.3 REPLACING THE DRIVE V-BELT The drive V-belt (a) is replaced by simply pulling off and inserting a new belt by hand. The belt sits loosely enough on the band to make this possible. There is no need to remove the band wheel (1) from the shaft.
