Hitachi CB 13F Blade Speed Selection Fig. W, Recommended Speeds, Speed Application Bladetype

Common causes of blade breakage:

⬤Poor guide alignment and adjustment.

⬤Forcing or twisting a wide blade around a short radius.

⬤Feeding too fast.

⬤Dull teeth or not enough set.

⬤Too much blade tension.

For longest wear and best cutting results, use the correct blade thickness width, and temper for the type of material you will cut.

When sawing small curves and delicate work, use narrow blades. Otherwise, use the widest blade possible, For cutting wood and similar materials with this bandsaw, purchase blades in widths up to 1/2”, and a length of 80”.

Do not cut ferrous metals with this band saw.
