Excessive blade breakage

Premature blade dulling

Bad cuts (crooked)

	Probable Cause		Suggested remedy

1.	Material loose in vise.	1.	Clamp work securely.
2.	Incorrect speed or feed.	2.	Check Machinist’s Handbook for
			speed/feed appropriate for the
			material being cut.
3.	Teeth too coarse for material.	3.	Check Machinist’s Handbook for
			recommended blade type.
4.	Incorrect blade tension.	4.	Adjust blade tension to the point
			where the blade just does not slip
			on the wheel.
5.	Saw blade is in contact with	5.	Start the motor before placing the
	workpiece before the saw is started.		saw on the workpiece.
6.	Blade rubs on the wheel flange.
7.	Misaligned guides.	6.	Adjust blade tracking.
7.	Misaligned guides.
8.	Cracking at weld.	7.	Adjust guides.
8.	Cracking at weld.
		8.	Longer annealing cycle.

1.	Blade teeth too coarse.	1.	Use a finer tooth blade.
2.	Blade speed too high.	2.	Try a lower blade speed.
3.	Inadequate feed pressure.	3.	Decrease spring tension.
4.	Hard spots in workpiece or scale	4.	Increase feed pressure (hard
	on/in workpiece.		spots). Reduce speed, increase
			feed pressure (Scale).
5.	Work hardening of material	5.	Increase feed pressure by reducing
	(especially stainless steel).		spring tension.
6.	Insufficient blade tension.	6.	Increase tension to proper level.
7.	Operating saw without pressure on	7.	Do not run blade at idle in/on
	workpiece.		material.

1.	Workpiece not square with blade.	1.	Adjust vise so it is square with the
			blade. (Always clamp the workpiece
			tightly in the vise.)
2.	Feed pressure too fast.	2.	Decrease pressure.
3.	Guide bearings not adjusted	3.	Adjust guide bearing clearance to
	properly.		0.001 inch (0.002 inch maximum).
4.	Inadequate blade tension.	4.	Gradually increase blade tension.
5.	Span between the two blade guides	5.	Move blade guide bracket closer to
	too wide.		work.
6.	Dull blade.	6.	Replace blade.
7.	Incorrect blade speed.	7.	Check blade speed (refer to Figure
			5).
8.	Blade guide assembly is loose.	8.	Tighten blade guide assembly.
9.	Blade guide bearing assembly	9.	Tighten blade guide bearing
