SYMPTOM CAUSE (S) POSSIBLE CORRECTIVE ACTION
1. Incorrect blade tension ust does not slip on wheel 1. Adjust to where blade j
2. Incorrect speed or feed 2. Check Machinist Handbook
3. Material loose in vise 3. Clamp work securely
Excessive Blade 4. Blade rubs on wheel flange 4. Adjust wheel alignment
Breakage r material Machinist Handbook for recommended blade 5. Teeth too coarse fo 5. Check
6. Teeth in contact with work before saw is started
6. Place blade in contact work after motor is started
7. Misaligned guides 7. Adjust
8. Blade too thick for wheel diameter 8. Use thinner blade
9. Cracking at weld 9. Make longer annealing cycle
1. Teeth too coarse 1. Use finer tooth blade
2. Too much speed 2. Try next lower speed
Permanent Blade . Inadequate feed pressure 3.3 Decrease spring tension on side of saw
Dulling 4. Hard spots or scale in/on material 4. Reduce speed increase feed pressure (Scale)
increase feed pressure (Hard Spots)
5. Work hardening of material (especially
stainless
5. Increase feed pressure by reducing spring tension
steel)
6. Blade installed backwards 6. Remove blade twist inside out and reinstall blade.

3. Blade is too coarse for work (Pipes especially) 3. Use finer blade
slow (Heavier, softer material)4. Blade is too fine for work
4. Use coarser blade
5. Gear not aligned properly 5. Adjust gears so that worm is in center of gear
6. Gears need lubrication 6. Check oil bath
7. Idler wheel needs lubrication 7. Oil bearing/shaft on idler wheel
