Adjusting the Blade Tension
This tracking adjustment is required to have the
blade run dead center on the rubber tyres of the
band saw wheels:
● Turning the setting knob clockwise increases
the blade tension.
● Turning the setting knob counter - clockwise
reduces the blade tension.
Band Saw Blade Alignment
If the band saw blade does not run in the centre
of the rubber tyres, the tracking needs to be
corrected by adjusting the tilt of the upper band
saw wheel:
1. Loosen locking nut.
2. Turn setting knob:
● Turn setting knob clockwise if the band saw
blade runs towards the front of the saw.
● Turn setting knob counter- clockwise if the
band saw blade runs towards the rear of the saw.
3. Tighten locking nut.
Upper Blade Guide Alignment
The upper blade guide consists of:
● a thrust bearing (supports the band saw blade
from the rear),
● two guide pins (providing lateral support).
The bearing and guide pins need to be readjusted
after every band saw blade change or tracking.
Thrust bearing adjustment
1. If necessary, align and tighten the band saw
blade.
2. Loosen the thrust bearing’s locking screw.
3. Adjust thrust bearing position (distance thrust
bearing - band saw blade = 0.5 mm
- if the band saw blade is turned by hand, it shall
not touch the thrust bearing.
NOTE: Periodically check all bearings
for wear, if necessary replace both
guide bearings at the same time.
