1.Release both cam locking levers.

2.Slide the table extension on the side your workpiece will be needing support, and tighten both cam locking

levers.

Slide the extension out until the correct measurement is displayed on the tube scale. GENERAL CUTTING

Fig. T-1

WARNING

For your safety, read and understand all GENERAL and SPECIFIC 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 close to your work, 1/8 "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 blade need little pressure for cutting. Steadily move the workpiece against the blade without forcing it. To avoid twisting the blade, do not turn sharp comers, 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 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. U)

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. V)

CAUTION: blade teeth are sharp. Use care when handling a saw blade.

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.
