11. TROUBLE SHOOTING 
 

Symptom 

  Possible Cause(s) 

  Corrective Action 

  Excessive Blade   
  Breakage 

1. Materials loosen in vise. 
2. Incorrect speed or feed 
3.Blade teeth spacing too large 
 
4. Material too coarse 
 
5. Incorrect blade tension 
 
6.Teeth in contact with material 
before saw is started 
 
7. Blade rubs on wheel flange 
8. Miss-aligned guide bearings 
9. Blade too thick 
10 Cracking at weld 
 

1. Clamp work securely 
2. Adjust speed or feed 
3. Replace with a small 

teeth spacing blade 

4. Use a blade of slow 

speed    and small teeth 
spacing 

5. Adjust to where blade just 

does not slip on wheel 

6. Place blade in contact     

with work after motor is   
starred 

7. Adjust wheel alignment 
8. Adjust guide bearings 
9. Use thinner blade 

10. Weld again, note the 
weld skill. 

  Premature Blade 
Dulling   

1. Teeth too coarse 
2. Too much speed 
3. Inadequate feed pressure 
 
4.Hard spots or scale on material   
 
5. Work hardening of material.   
 
6.Blade twist 
 
7. Insufficient blade 
 
8. Blade slide 

1. Use finer teeth 
2. Decrease speed 
3. Decrease spring tension 

on    side of saw 

4. Reduce speed, increase 

feed pressure 

5. Increase feed pressure by 

reducing spring tension 

6. Replace with a new blade, 

and adjust blade tension 

7. Tighten blade tension     

adjustable knob 

8. Tighten blade tension 

  Unusual Wear on   
  Side/Back of Blade 

1.  Blade guides worn. 
2.  Blade guide bearings not 

adjust properly 

3.  Blade guide bearing bracket 

is loose 

1.  Replace.
