4. Trouble Shooting Guide
Problem
Probable Cause
Excessive Blade
1 Material loose in vise
2 Teeth too course for
material.
3 Incorrect blade tension
4 Teeth in contact with work
before saw is started.
5 Blade rubs on wheel flange.
6 Misaligned guides
7 Blade too thick for wheel
8 Cracking at weld
Premature
1 Teeth too course
Blade
2 Inadequate feed pressure
3 Hard spots or scale in/on
material.
4 Work hardening of material
(especially stainless steel)
5 Blade installed backwards
6 Insufficient blade tension
Bad Cuts
I Blade is too coarse
2 Work not square
3 Feed pressure too great
Solution
1 Clamp work securely
2 Check Machinist Handbook
for recommended
blade type.
3 Adjust to where blade just
does not slip on wheel.
4 Place blade in contact with
work after motor is started.
5 Adjust wheel alignment
6 Adjust
7 Use thinner blade
8 Make longer annealing cycle.
1 Use finer tooth blade
2 Decrease spring tension on
side of saw
3 Reduce speed, increase feed
pressure (Scale). Increase feed
pressure (Hard Spots).
4 Increase feed pressure by
reducing spring tension.
5 Remove blade, twist inside out
and reinstall blade.
6 Increase tension to proper level.
1 Replace with finer blade.
2 Adjust vise to be square with
blade. Always clamp work
tightly in vise.
3 Reduce pressure by increasing
