14.2.3 Blade tension
Too much tension: The band saw blade can break
Too less tension: The band saw blade can slip and stop
Raise upper blade guide fully.
Taking the blade width into consideration, turn the knob to adjust tension (Fig.j; 1j).
Check tension by pushing with a finger, halfway between table and upper
Turning the setting knob clockwise increase the blade tension
Tuning the setting knob counter-clockwise reduce the blade tension
After the end of the work dissipate the band saw blade a little bit.
14.2.4 Blade guide
The blade guide is used to adjust the distance from the band saw blade to the guide bearing.
Do not adjust the sawband guidance when the machine
is working!
Heavy injuries on hands and arms are possible!
Sawband guidance can be adjusted only after the
sawband direction and the sawband tension has been
proofed.
Before you adjust the sawband guidance switch off the
machine and wait until the sawband is standing completely
still.
Upper blade guide (Fig.k; 3k)
The height of blade guide needs to be adjusted: prior to every cutting/operation, to accommodate
the height of work piece (the upper blade guide should be set approx. 3mm above the
workpiece).
Set upper blade guide with the adjusting knob to the desired height by loosening the
locking knob (1k). After adjustment (2k), be sure to tighten the lock knob (1k).
Loosen the knob (4k), and adjust bearing holder, so that guide bearing is positioned 1or
2mm from bottom of blade. Retighten the knob
Loosen the knob (5k), and adjust trust bearing to a position of 0.5mm from rear of blade.
Retighten the knob (5k).
Loosen the bolt (6k), and adjust guide bearing to a position 0.5mm away from blade.
Retighten the bolt (6k).
Lower blade guide (Fig.l)
