Trouble
Cracks on back edge of blade.
Blade breaks prematurely.
Blade breaks close to weld.
Premature dulling of saw teeth.
Blade binds in the workpiece.
Probable Cause | Remedy | |
|
| |
Workpiece being fed too quickly. | Reduce feed speed to lessen strain on | |
the blade. | ||
| ||
|
| |
Welding on blade not perfectly aligned. | Eliminate the welded part, and | |
properly; or acquire a new blade. | ||
| ||
|
| |
Support bearing is worn; caused by | Replace support bearing. Adjust new | |
bearing according to instructions (see | ||
constant contact with back of blade. | ||
pages 18 and 19). | ||
| ||
|
| |
Feed force too great. | Reduce feed force. | |
|
| |
Blade pitch too coarse. | Refer to blade selection chart; use finer | |
pitch blade (see page 28). | ||
| ||
|
| |
Support bearing not properly supporting | Check support bearing for correct | |
position and signs of wear. Adjust or | ||
blade. | ||
replace as needed. | ||
| ||
|
| |
Blade tensioned too tightly. | Reduce tension (see page 16). | |
|
| |
Blade overheated during welding. | Have blade annealed, or eliminate | |
brittle part and weld correctly. | ||
| ||
|
| |
Blade cooled too rapidly after welding. | Have blade annealed, or eliminate | |
brittle part and weld correctly. | ||
| ||
|
| |
Blade “pitch” too fine. | Refer to blade selection chart (page | |
28). Use blade with coarser pitch. | ||
| ||
|
| |
Feed pressure too light. | Increase feed pressure. | |
|
| |
Cutting rate too low. | Increase feed pressure and cutting rate. | |
|
| |
Incorrect choice of blade. | ||
blade from the chart (page 28). | ||

| |
Chipped tooth or foreign object lodged | Stop the saw and remove lodged | |
in cut. | particle. Replace blade if damaged. | |
