BASIC SAW OPERATIONS
"ON/OFF" SWITCH (FIG. T)
The keyed switch is intended to prevent unauthorized
use of the band saw.
I. To turn the band saw ON insert the black switch key
(1) into the key slot in the center of the switch (2).
2. Push the key firmly into the slot, then push switch (2)
to the ON position to start the band saw.
3. To turn the band saw OFF push the switch (2) to the
OFF position.
4. Remove the black switch key, when the saw has
come to a complete stop, by gently pulling it outward.
WARNING
!
Remove the black switch key (1) whenever the saw is
not in use. Place it in a safe place and out of reach of
children.

GENERAL CUTTING
WARNING
!
For your safety, read and understand all SAFETY
INSTRUCTIONS on pages 4 - 6 before using the
band saw.
Operating band saws involves a certain amount of
hazard. Before attempting regular work, use scrap
lumber to check the settings, and to get the feel of
operating the band saw. Read instructions and plan
your work before cutting a workpiece.
Do not turn the power ON until after you have made all
adjustments, checked that the guard is in place, and
turned the wheel by hand to make sure all parts work
properly. Always keep the guide assembly 1/8 in. (3.2
mm) above the workpiece.
Do not force the workpiece against the blade.
Light contact permits easier cutting and prevents
unwanted friction and heating of the blade.
Sharp saw blades need little pressure for cutting.
Steadily move the workpiece against the blade without
forcing it.

OPERATION

To avoid twisting the blade do not turn sharp corners;
saw around corners.
A band saw is basically a "curve-cutting" saw. It is not
capable of doing intricate inside cutting as can be done
with a scroll saw.
It is also used for straight line operations such as
crosscutting, ripping, mitering, beveling, compound
cutting, and resawing.
WARNING
!
To avoid blade breakage, fire or other damage or injury,
NEVER use this band saw to cut metals.
CUTTING CURVES
When cutting curves, carefully turn the workpiece so the
blade may follow 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.
ClRCLE CUTTING (FIG. U)
1. Adjust the guide assembly to 1/8 in.(3.2 mm) above
the workpiece.
2. Use both hands while feeding the work into the
blade. Hold the workpiece firmly against the table.
Do not force the work and operate with gentle
pressure.
3. The smallest diameter circle that can be cut is
determined by the width of the blade. For example, a
1/4 in.(6.4 mm) wide blade will cut a minimum
diameter of approximately 1-1/2 in.(38.1 mm).
