OPERATION
SWITCH BOX
Use the power switch (Fig. 14 – 1) to turn the saw ON or OFF.
Remove the yellow safety key when the saw is OFF to prevent
unauthorized use. Store the safety key in a safe place out of the
reach of children.
GENERAL CUTTING GUIDELINES
WARNING!
Operating a band saw involves a certain
amount of risk. Read the instructions and plan your work be-
fore cutting a workpiece.
1. Make a test cut on scrap wood to test the settings and get the
hang of operating the band saw.
2. Make all adjustments with the band saw turned OFF and un-
plugged.
3. Make sure the upper guard is close to the upper face of your
workpiece (see “RAISING AND LOWERING THE UPPER BLADE
GUIDE”).
4. Always use the push stick when cutting intricate or narrow
workpieces. Keep fingers, hands, and other beloved body parts
away from the blade!
5. Do not force the workpiece against the blade. Let the tool do
the work. Light contact gives easier cutting and prevents excess
friction, which will prolong the life of the blade and prevents work-
piece burning.

6. Always use dust collection. A 2” dust port (Fig. 15 - 1) is located on the back of the saw, next to the motor (see
“KNOW YOUR BANDSAW”). Use a hose clamp (if necessary) to secure the adapter or dust hose to the dust port.
7. The band saw is most suitable for straight-line cutting (cross-cutting, ripping, miter cutting, beveling, compound
cutting, and resawing). While it can certainly cut curves, it is not a scroll saw, and cannot perform the same kinds
of cuts. Do not cut sharp corners; instead, saw around corners.
CUTTING CURVES
When freehand-cutting curves, carefully turn the workpiece so that the blade follows the cut line 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
(that is, the teeth are further apart). When a blade has more set, the workpiece turns more easily, but you will get a
rougher cut.
When changing a cut, do not withdraw the workpiece from the blade – the workpiece may drag the blade off the
wheels. Instead, turn the workpiece and cut out through the scrap section of the workpiece. When cutting long
curves, make relief cuts as you go along.
