Troubleshooting
Fault
1. Material loose in vise.
2. Incorrect speed or feed.
3. Teeth too coarse for material.
Excessive blade
4. Incorrect blade tension.
breakage
5. Saw blade is in contact with work-
6. Misaligned guides.
7. Cracking at weld.
1. Blade teeth too coarse.
2. Blade speed too high.
3. Inadequate feed pressure.
4. Hard spots in workpiece or scale
Premature blade
dulling
5. Work hardening of material
6. Insufficient blade tension.
7. Operating saw without pressure on
1. Workpiece not square with blade.
2. Feed pressure too fast.
3. Guide bearings not adjusted
4. Inadequate blade tension.
5. Span between the two blade guides
Bad cuts (crooked)
6. Dull blade.
7. Incorrect blade speed.
8. Blade guide assembly is loose.
9. Blade guide bearing assembly loose.
10. Blade track too far away from wheel
11. Guide bearing worn.
Probable Cause

flanges.
1. Clamp work securely.
2. Check Machinist's Handbook for
speed/feed
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 guides.
7. Longer annealing cycle.
1. Use a finer tooth blade.
2. Try a lower blade speed.
3. Decrease spring tension.
4. Increase feed pressure (hard spots).
Reduce speed, increase feed pres-
sure (Scale).
5. Increase feed pressure by reducing
spring tension.
6. Increase tension to proper level.
7. Do not run blade at idle in/on
material.
1. Adjust vise so it is square with the
blade. (Always clamp the workpiece
tightly in the vise.)
2. Decrease pressure.
3. Adjust guide bearing clearance to
0.001 inch (0.002 inch maximum).
4. Gradually increase blade tension.
5. Move blade guide bracket closer to
work.
6. Replace blade.
7. Check blade speed.
8. Tighten blade guide assembly.
9. Tighten blade guide bearing
assembly.
10. Adjust blade tracking.
11. Replace worn bearing.
