basic band saw operation
A band saw is basically a "curve cutting" machine It is also used for
This band saw is designed to cut wood and wood like products only,
For general type scroll cutting, follow the pattern lines by pushing and turning the workpiece at the same
time Don'ttry to turn the workpiece while engaged in
the blade without pushing it; the workpiece could bind or twist the blade
A curve cut is best performed by keeping the pattern line in line with the blade while turning the workpiece before the radius of the curve is cut,. The blade
should cut in the middle of the pattern line (saw kerf) since wood cutting band saw blades are thin

WARNING: To avoid blade contact, adjUst the upper guide assembly to just clear the workpiece,
l r, 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, but allow the blade to cuL
2The smallest diameter'circle that can be cut out is
,determined by the width of the blade,, A 1/4" wide
blade will cut a minimum diameter'of approximate- ly
Relief cuts are made when an intricate curve (too small a radius for the blade) is to be cut buL A relief
cut is made by cutting through the scrap section of workpiece to curve in pattern line, then carefully backing blade out Several relief cuts should be made for intricate curves, then follow pattern line as sec- tions are cut off of curve "relieving" blade pressure,
WRONG - Not planning ahead for cutting a curve could bind or twist blade if workpiece is forced
