CORRECTIVE ACTION
1.
Adjust blade so it 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.

8.
Use thinner blade.
9.
Allow blade to cool longer between cuts.
1.
Use finer tooth blade.
2.
Try next lowest speed.
3.
Decrease spring tension on side of saw.
4.
Reduce speed increase feed pressure (scale) or
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.
1.
Adjust vise to be square with blade. Always
clamp work tightly in vise.
2.
