Troubleshooting
| Feed pressure too great | 1. | Observe chip formation to be sure cutting is efficient. |
| Guide bearings not adjusted properly | 1. | Adjust guide bearings according to instruction in this |
|
| manual. | |
| Inadequate blade tension | 1. | Increase blade tension so blade does not slip on the |
|
| wheels. | |
| Blade guides incorrectly spaced | 1. | Move guide brackets until they just clear the workpiece |
|
| while making a complete cut. | |
|
| 2. | For small section pieces, be sure the blade is sharp |
|
| and correctly tensioned. Use less feed pressure. | |
| Dull blade | 1. | Replace blade when it dulls. |
|
| 2. | Consider using a coolant, if not already used. |
| Incorrect speed | 1. | Check technical literature for recommended speeds |
|
| and blade type for material being cut | |
|
| formation to verify efficient cutting. | |
| Blade guide assembly loose | 1. Tighten guide bracket. | |
| Blade guide bearing assembly loose | 1. | Check tightness of bearing seat bolt. |
| Blade tracking too far away from wheel | 1. | Use paper cutting method of setting blade tracking. |
| flanges |
|
|
| Worn upper wheel bearings | 1. | Replace bearings if worn. |
| Loose upper wheel mounting assembly | 1. | Tighten all bolts securing wheel to arm. |
Rough | Too much feed or speed | 1. | Try one step lower speed and observe chip formation |
cuts |
| for efficient cutting/feed rate. | |
| Blade too coarse | 1. | Use finer blade. Check with suppliers for recommen- |
|
| dations for the material you are cutting. | |
| Incorrect blade for material | 1. | Check with blade suppliers for recommendations for |
|
| exotic or unusual materials or specifications. | |
Blade | Cut is binding blade | 1. | Be sure workpiece is flat on saw table. |
twisting |
| 2. | Decrease feed pressure. |
| Too much blade tension | 1. | Reduce tension to just above point where blade slips. |
| Loose guide bearing eccentrics | 1. | Check eccentric jam nuts for tightness. |
| Worn guide bearings | 1. | Check guide bearings for wear. Replace if necessary. |
| Incorrect guide bearing adjustment | 1. | Adjust guide bearings according to instructions in this |
|
| manual. | |
| Loose guide bearing bracket | 1. | Tighten bracket on saw arm. |
| Loose bearing seat attachment screw | 1. | Tighten bearing seat attachment screw |
|
| for vertical and parallel. | |
Unusual | Blade guides worn | 1. | Replace. |
wear on | Blade guide bearings not adjusted properly | 1. | Check and adjust for proper clearance. |
side/back of | Blade guide bearing bracket loose | 1. | Tighten bracket to saw arm. |
blade | Blade running on wheel flange | 1. | Adjust blade tracking using the paper cutting method. |
Breaking | Teeth too coarse for work | 1. | Use blade with finer pitch. |
teeth | Too heavy feed | 1. | Decrease feed rate |
|
| efficient cutting. | |
| Too slow speed | 1. | Increase blade speed. Check technical literature or |
|
| blade or workpiece supplier for blade speed recommenda- | |
|
| tions. | |
| Vibrating work piece | 1. | Be sure vise is tight. |
|
| 2. | Support slender cross section or long workpieces with |
|
| appropriate | |
|
| 3. | If stacking pieces in the vise, be sure all workpieces |
|
| are securely captured by the vise. | |
| Tooth gullets loading | 1. | Use coarser blade or one with a tooth geometry more |
|
| appropriate to the workpiece being cut. | |
| Blade in contact with workpiece before motor | 1. | Always allow motor to come fully up to speed before |
| is started | beginning cut. | |
Motor | Blade tension too high | 1. | Decrease blade tension to just above slip point. |
running too | Blade too coarse for work (pipes, especially) | 1. | Use finer pitch blade. |
hot | Blade is too fine for work (heavier, soft | 1. | Use coarser blade. |
| material) |
|
|
| Worn transmission and worm gear | 1. | Replace gears in transmission gearbox. |
| Gears need lubrication | 1. | Check gearbox and add oil as required. |
