SYMPTOM
POSSIBLE CAUSE
CORRECTIVE ACTION
Excessive Blade
Breakage
1. Incorrect blade tension
2. Incorrect speed or feed
3. Material loose in vise
4. Blade rubs on wheel flange
5. Teeth too coarse for material
6. Teeth in contact with work before
saw is started
7. Misaligned guides
8. Blade too thick for wheel diameter
9. Cracking at weld
1. Adjust to where blade just does not
slip on wheel
2. Check machinist handbook
3. Clamp work securely
4. Adjust wheel alignment
5. Check machinist handbook for
recommended blade type
6. Place blade in contact work after
motor is started
7. Adjust
8. Use thinner blade
9. Make longer annealing cycle
Premature Blade
Dulling
1. Teeth too coarse
2. Too much speed
3. Inadequate feed pressure
4. Hard spots or scale in/on material
5. Work hardening of material (specially
stainless steel)
6. Blade installed backwards
7. Insufficient blade tension
1. Use finer teeth blade
2. Try next lower speed
3. Decrease spring tension on side of
saw
4. Reduce speed increase feed
pressure (scale) Increase feed
pressure (hard spots)
5. Increase feed pressure by reducing
spring tension
6. Remove blade twist inside out and
reinstall
7. Increase tension to proper level
Blade Cuts
(Crooked)
1. Work no square
2. Feed pressure too great
3. Guide bearing not adjusted properly
4. Inadequate blade tension
5. Blade guides spaced out too much
6. Dull blade
7. Speed Incorrect
8. Blade guide assembly loose
9. Blade guide bearing assembly loose
10. Blade tracks too far away from wheel
flanges.
1. Adjust the vise to be square with the
blade and always clamp the work-
piece
2. Reduce pressure by increasing
spring tension on side of the saw.
3. Adjust guide bearing to 001 greater
than maximum thickness, including
weld of the saw.
4. Increase blade tension a little at a
time
5. Move guide to the work-piece as
close as possible
6. Replace blade
7. Check manual for recommended
speeds
8. Tighten
9. Tighten
10. Redo the blade tracking adjustment
according to the manual
