FUNCTIONAL DESCRIPTION
Tensioning the Band saw Blade
CAUTION:
Too much tension can cause the band saw blade to break. Too little tension
can cause the driven band saw wheel to slip and the band saw blade to stop.
1. Raise upper blade guide fully.
Using the scale as guide, and taking the blade width into consideration, turn the
knob to adjust tension. (After adjusting, check tension as shown in item 2.)
2. Checking the blade tension:
- check tension by pushing with a finger, halfway between table and upper blade
guide, against the side of the blade (the blade should flex not more than 1-
2mm)
- check adjustment at the blade tension indicator. The scale indicates the correct
adjustment in dependence on the band saw blade width.
3. Correct tension if necessary:
- turning the setting knob clockwise increases the blade tension.
- turning the setting knob counter-clockwise reduces the blade tension.
Aligning the band saw blade
If the band saw blade does not run in the center of the rubber tyres, the tracking
needs to be corrected by adjusting the tilt of the upper band saw wheel:
1. Loosen lock knob.
2. Manually rotate the upper wheel, taking care not to touch the blade.
3. 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 toward the rear of
the saw
4. After adjusting, always close the lock knob.
