Troubleshooting
Fault
Excessive blade
breakage
Premature blade
dulling
Bad cuts
(out-of-square)
Bad cuts (rough)
Probable cause
1. Material loose in vise.
2. Incorrect speed or feed.
3. Teeth too coarse for material.
4. Incorrect blade tension.
5. Saw blade contacts workpiece
before the saw is started.
6. Blade rubs on the wheel flange.
7. Misaligned guides.
8. Cracking at weld.
1. Blade teeth too coarse.
2. Blade speed too high.
3. Hard spots in workpiece or scale
on/in workpiece.
4. Work hardening of material
(especially stainless steel).
5. Insufficient blade tension.
6. Operating saw without pressure
on workpiece.
1. Feed pressure too fast.
2. Guide bearings not adjusted
properly.
3. Inadequate blade tension.
4. Dull blade.
5. Incorrect blade speed.
6. Blade guide assembly is loose.
7. Blade guide bearing assembly
loose.
8. Blade track too far away from
wheel flanges.
9. Guide bearing worn.
1. Blade speed too high for feed
pressure.
2. Blade is too coarse.
Suggested remedy
1. Clamp work securely.
2. Refer to Figure 6 or check
Machinist’s Handbook for speed/
feed appropriate for the material
being cut.
3. Check Machinist’s Handbook for
recommended blade type.
4. Adjust blade tension to the point
where the blade just does not slip
on the wheel.
5. Start the motor before placing the
saw on the workpiece.
6. Adjust blade tracking.
7. Adjust guides.
8. Longer annealing cycle.
1. Use a finer tooth blade.
2. Try a lower blade speed.
3. Increase feed pressure (hard
spots). Reduce speed, increase
feed pressure (scale).
4. Increase feed pressure by reduc-
ing spring tension.
5. Increase tension to proper level.
6. Do not run blade at idle in/on
material.
1. Decrease pressure.
2. Adjust guide bearing clearance to
0.001 inch (0.002 inch maximum).
3. Gradually increase blade tension.
4. Replace blade.
5. Check blade speed
(see Figure 6).
6. Tighten blade guide assembly.
7. Tighten blade guide bearing
assembly.
8. Adjust blade tracking.
9. Replace worn bearing.
1. Reduce blade speed and feed
pressure.
2. Replace with finer blade.
