Possible Solution
1. Use the correct holding fixture and reclamp
workpiece.
2. Re-tension or replace blade (Page 34).
3. Clean metal chips from wheels.
4. Check/replace wheel bearing.
5. Replace or dress rubber tires (Page 45).
6. Re-tension/replace blade (Page 34).
7. Replace wheels.
8. Tighten loose component.
9. Replace/adjust the V-belt (Page 45).
10. Replace bad wheel.
11. Test/repair/replace.

blade support/guides (Page 25).
2. Inspect weld and re-weld blade if necessary (Page
38), or replace blade (Page 34).
1. Reduce feed rate/increase blade speed.
2. Tighten/clean/replace V-belt(s) (Page 45).
3. Install a blade with more suitable TPI or different
style of teeth (Page 31).
4. Replace blade, adjust guides and tracking (see
Page 23).
5. Use a blade with at least 2 teeth contacting the
material at all times (Page 31).
6. Clean wheels and increase blade tension
(Page 23).
7. Use applicable cutting fluid/lubricant.
1. Calibrate table (Page 50). Tighten any loose
fasteners.
2. Tighten any loose hardware or lock levers. Align the
guide post (Page 51).
1. Replace blade, and complete blade break-in
procedure (Page 35).
2. Use a blade that has larger gullets to carry out
material.
3. Use a coarser-tooth blade, adjust feed rate, adjust
blade speed, make sure the blade brush is working.
4. Replace the blade with a special blade for cutting
hardened materials.
1. Clean and lubricate the leadscrew (Page 43).
2. Readjust bevel gears to reduce backlash (Page 52).
3. Replace bearing or readjust leadscrew collar
(Page 52).
4. Replace linkage bolts, pins, and re-bush any worn
pin holes.
5. Replace leadscrew or leadscrew nut.
