4. Use a wider arc on outside cuts, or use relief cuts
to make tight inside cuts (Page 53).
5. Replace blade (Page 50).
6. Adjust blade tracking (Page 32).
7. Adjust support bearings/blade guide discs proper-
ly, so guides cannot contact teeth during operation
(Pages 33 & 34).

2. Blade TPI is too coarse.
3. Blade is loose and fluttering.
4. Blade tracking is incorrect.
5. Blade has missing/bent teeth, or faulty
weld.
1. Decrease feed rate; ensure proper TPI (Page 48).
2. Use correct blade for material and speed of cut
(Page 44).
3. Adjust blade tension as required (Page 30).
4. Adjust blade tracking (Page 27).
5. Replace blade (Page 50).
