Trouble Probable Cause Remedy
Cuts not square. Feed pressure too great. Decrease feed pressure.
90° angle stop is not set correctly. Adjust stop until blade is square with vise.
Incorrect blade toothing in relation to
workpiece.
Check Machinery’s Handbook for
recommended blade type.
Blade is worn, cutting crooked. Replace blade.
Incorrect adjustment of bearing guides
and guide assembly.
Re-adjust guide assemblies.
Workpiece incorrectly positioned in vise. Check positioning and clamping in vise.
Poor blade tension. Check and correct if needed.
Finished surface of
workpiece is rough,
unsatisfactory.
Blade is dull. Replace blade.
Improper blade for cutting operation.
Check Machinery’s Handbook for blade
recommendations.
Downfeed rate too fast. Reduce downfeed rate.
Blade tension too low. Increase blade tension.
Excessive blade
breakage.
Incorrect blade tension. Adjust blade tension.
Incorrect blade speed or downfeed rate. Adjust acccordingly.
Workpiece loose in vise. Clamp workpiece securely.
Blade rubs on wheel flange. Adjust blade tracking.
Teeth too coarse for material.
Use appropriate blade for material being
cut.
Teeth in contact with workpiece before
saw is started.
Start motor before blade contacts
workpiece.
Blade guides are misaligned. Adjust blade guides as needed.
Blade too thick for wheel diameter. Use thinner blade.
Cracking at weld; poor annealing of blade. Replace blade.
Premature blade
dulling.
Teeth too coarse. Use finer tooth blade.
Blade speed too fast. Reduce speed.
Inadequate downfeed rate. Adjust cylinder dial setting as needed.
Hard spots or scale on material.
Scale: Reduce speed and increase
downfeed rate. Hard Spots: Increase
downfeed rate.
Work hardening of material (especially
stainless steel)
Increase downfeed rate.
Blade installed backwards.
Remove blade, twist inside-out and re-
install.
Insufficient blade tension. Adjust as needed.
Unusual wear on
