Troubleshooting
Problem | Probable cause |
| Potential solutions |
Excessive | Material loose in the vise | 1. | Use more pressure to tighten vise. |
blade |
| 2. | Check stationary jaw pivot and lock bolts for tightness. |
breakage |
| 3. | Check quick release handle nut for excessive tightness |
|
| ||
|
| from tilting when tightening. | |
|
| 4. | If you are stacking multiple pieces in the vise, be sure |
|
| all of the pieces are captured by the vise pressure. | |
| Incorrect feed or speed | 1. | Check technical literature for recommended feeds and |
|
| speeds for the material and blade you are using. | |
|
| 2. | Check chip formation to adjust speed and feed to |
|
| correct rate when sawing. | |
| Incorrect blade tension | 1. | Adjust blade tension to where it just does not slip on |
|
| the wheel. | |
| Teeth in contact with work before saw is | 1. | Be sure the saw motor has come fully up to speed |
| started | before beginning a cut and be sure the blade is not resting | |
|
| on the workpiece before the motor has come up to full | |
|
| speed. | |
| Blade rubs on wheel flange | 1. | Use paper cutting method of adjusting blade tracking. |
|
| See Blade Tracking Adjustment. | |
|
| 2. | Check drive and idler wheels for looseness in mount- |
|
| ing parts or worn/damaged bearings. | |
| Misaligned blade guides | 1. | Adjust blade guides. |
| Blade too thick for wheel diameter | 1. | Use a thinner blade. Check with your blade supplier |
|
| for recommendations on blade thickness for a specific | |
|
| wheel diameter. | |
| Cracking at weld | 1. | Replace blade. |
Premature | Teeth too coarse | 1. | Use finer tooth blade. |
blade | Too much blade speed | 1. | Try next lower speed or check technical literature for |
dulling |
| specific recommendations regarding speeds for specific | |
|
| blade and material being cut. | |
|
| 2. | Check with materials supplier for recommendations on |
|
| the workpiece material supplied. | |
|
| 3. | If using coolant, check with supplier regarding correct |
|
| coolant for the job. | |
| Inadequate feed pressure | 1. | Increase pressure while observing chip formation to be |
|
| sure you are cutting efficiently. | |
| Hard spot or scale on material | 1. | Reduce speed of blade. |
|
| 2. | Increase feed pressure in scale or hard spots . |
| Work hardening of material (especially | 1. | Work hardening materials such as stainless require a |
| stainless steel) | heavy, continuous cut. Be sure you are using a sharp | |
|
| blade, then, if necessary, release some counterbalance | |
|
| spring pressure by loosening the tension nut if work | |
|
| hardening of the material is a problem. | |
| Blade installed backwards | 1. | Reinstall blade so teeth point toward right end of saw. |
| Incorrect coolant or no coolant | 1. | Check with materials supplier and/or blade supplier for |
|
| coolant recommendations. | |
|
| 2. | Check with coolant supplier for specific recommenda- |
|
| tions on the blade and material you are using. | |
| Insufficient blade tension | 1. | Increase tension so blade is above the slipping point. |
Crooked | Work not square | 1. | Adjust the stationary vise jaw so it is square to the |
cuts |
| blade. | |
|
| 2. | Clamp work tightly in the vise. |
|
| 3. | Check blade for vertical and adjust, if necessary. |
|
| 4. | Perform test cuts according to instructions on page |
|
| until cuts are satisfactorily square. | |
|
| 5. | Move guide bearings as close as possible to work |
|
| while still completing the cut. | |
|
| 6. | Check guide bearings, seats and brackets for possible |
|
| looseness or wear. | |
