LOWER BLADE GUIDES AND SUPPORT BEARING
(FIG. Z, AA)
To avoid injury, turn the switch OFF and disconnect the
saw from the power source before making any
adjustments. NEVER make adjustments with the machine
running.
NOTE: Make sure the blade is tensioned and tracking
properly. The lower blade guides and support bearings
should always be adjusted after the bIade is tensioned, the
tracking is adjusted, and the upper blade guides and upper
support bearings are properly adjusted.
Blade guides
1. Loosen both front hex socket screws (1) with a hex
wrench.
2. Move the guide blocks (2) as close to the sides of the
blade (3) as possible without pinching it.
3. Using the feeler gauge, measure the spaces between
the guide blocks and the blade. Adjust to 0.02".
4. Tighten the hex screws. (Fig. Z)
5. Loosen the side hex socket screw (4). Move the guide
block support bracket (6) in or out until the blocks are
just behind the saw teeth. Tighten the screw. (Fig. AA)
Support bearing
6. Loosen the bearing hex socket screw (7) with the hex
wrench.
7. Move the blade support bearing shaft (8) in or out until
the support bearing (9) is 1/64" behind the saw blade.
8. Tighten the bearing hex socket screw. (Fig. AA)
9. The back edge of the blade (3) should be positioned
1/16" to 1/8" from the right edge of the support bearing
(9), as shown. (Fig. Z)

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

GENERAL CUTTING
For your safety, read and understand all GENERAL and
SPECIFIC SAFETY INSTRUCTIONS on pages 3-5 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 ptan 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" 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.
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.
tt is also used for straight line operations such as
crosscutting, ripping, mitering, beveling, compound cutting,
and resawing.
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 follows without twisting. If the curve is so sharp that
you repeatedly back up and cut new kerr, 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. CC)
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".
