Breakage
1.Workpiece loose in vise
2.Incorrect feeding speed
3.Blade spacing to far
apart
4.Workpiece too coarse
5.Blade tension incorrect
6.Teeth contacting work-
piece before saw starts
7.Blade rubbing on wheels
8.Guide bearings out of
alignment
9.Blade cracking at weld
1.Secure workpiece in vise.
2.Adjust feeding speed.
3.Replace blade with smaller
teeth spacing.
4.Use slower blade speed.
5.Adjust blade tension so blade
does not slip on wheel.
6.Feed workpiece after band
saw starts.
7.Adjust wheel alignment.
8.Adjust guide bearings.
9.Re-weld blade.
Blade Dulls
Prematurely
1.Blade teeth too coarse
2.Speed set too high

4.Hard spots or scale on
workpiece
5.Blade twisting in guides
6. Blade not cutting properly
1.Change to blade with finer teeth.
2.Lower blade speed.
3.Adjust feed pressure. Allow blade
to do cutting of workpiece.
4.Reduce speed; increase feed
pressure.
5.Replace blade and adjust blade
tension.
6.Increase blade tension.
Unusual Wearing
on Blade Side or
Back
