WARNING
To avoid blade breakage, fire or other damage or injury,
NEVER use this band saw to cut ferrous metals.
CUTTING CURVES
When cutting curves, carefully turn the workpiece so the
blade follows without twisting. If the curve is so sharp that you
repeatedly back up and cut new kerf, use a narrower blade,
or a blade with more set (teeth further apart). When a blade
has more set, the workpiece turns easier but the cut is
rougher.
When changing a cut, do not withdraw the workpiece from
the blade. The blade may get drawn off the wheels.
To change a cut, turn the workpiece and saw out through the
scrap material area.
When cutting long curves, make relief cuts as you go along.
CIRCLE CUTTING (Fig. P)
1. Adjust the guide assembly to 1/8" above the workpiece.
2. Use both hands while feeding the work into the blade.
Hold the workpiece firmly against the table. Use gentle
pressure. Do not force the work, ALLOW the blade
to cut.

3. The smallest diameter circle that can be cut is
determined by the width of the blade. For example, a
1/4" wide blade will cut a minimum diameter of
approximately 1-1/2".
BLADE SELECTION (Fig. Q)
CAUTION: Blade teeth are sharp. Use care when handling
a saw blade.

Blade Width
– 16 –
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 band saw, purchase
blades in widths up to 3/8", and a length of 63-1/2".
Do not cut ferrous metals with this band saw.
Common causes of blade breakage:
• Poor guide alignment and adjusting.
• Forcing or twisting a wide blade around a short radius.
• Feeding too fast.
• Dull teeth or not enough set.
• Too much blade tension.
• Setting top guide assembly too high above the workpiece.
• Lumpy or improperly finished braze or weld on the blade.
• Continuous running of blade when not cutting.

WARNING
To avoid possible injury or damage, NEVER use this band
saw to cut ferrous metals.
CAUTION: When cutting nonferrous metals, metal shavings
can react with wood dust and start a fire. To avoid this:
1. Disconnect any dust collection bag from the
band saw.
2. Remove all traces of wood dust from inside the saw.
3. Remove all metal shavings from inside the saw
before sawing wood again.
