Regulations.
THESE iNSTRUCTiONS.
Refer to them often and use them to instruct others.
POWER CONNECTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should
be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have
3-prong grounding type plugs and matching receptacle which will accept the machine's plug. Before connecting the
machine to the power line, make sure the switch (s) is in the "OFF" position and be sure that the electric current is of
the same characteristics as indicated on the machine. All line connections should make good contact. Running on low
voltage will damage the machine.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
MOTOR SPECiFiCATiONS
Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is inthe "OFF" position.
GROUNDING iNSTRUCTiONS
This machine must be grounded while in use to protect the operator from electric shock.
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. This machine is equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conduc-tor can result in risk of electric shock. The conductor
with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding
conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that
accept the machine's plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less
than 150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the
machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks
like the adapter illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor receptacle as
shown in Fig. B if a properly grounded outlet is not available. The temporary adapter should be used only until
a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the
like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet
box. Whenever the adapter is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
In all cases, make certain that the receptacle in question is properly grounded. If you are not sure,
have a qualified electrician check the receptacle.

EXTENSION CORDS
Use proper extension cords. Make sure
your extension cord is in good condition and is a 3=
wire extension cord which has a 3=prong grounding
type plug and matching receptacle which will accept
the machine's plug. When using an extension cord,
be sure to use one heavy enough to carry the current
of the machine. An undersized cord will cause a drop
in line voltage, resulting in loss of power and over=
heating. Fig. D=I or D=2, shows the correct gauge to
use depending on the cord length, if in doubt, use
the next heavier gauge. The smaller the gauge num-
ber, the heavier the cord.

The lower blade guides and blade support bearing
should be adjusted at the same time as the upper guides
and support bearings as follows:
1. Loosen two screws (A) Fig. 29, and move guides
(B) as close as possible to the sides of the blade.
Be careful not to pinch the blade. Tighten the two
screws (A). NOTE: In Fig. 29, the table has been
removed for clarity.
2. The front edge of the blade guides (B) Fig. 29 should
be adjusted so they are just behind the "gullets" of
the blade teeth. Loosen screw (C), and move the
assembly (D) in or out as necessary. Tighten screw
(C).
3. The lower blade support thrust bearing (E) Fig.
29 prevents the saw blade from being pushed
back too far during cutting. The support bearing
should be adjusted approximately 1/32" behind
the blade. Loosen screw (F) Fig. 29, and move the
bearing shaft (G) in or out as necessary. Tighten
screw (F).
4. The lower blade support bearing (E) Fig. 29 should
also be adjusted so that the blade overlaps the
outside diameter of the ball bearing by approximately
1/8". The blade support bearing (E) is set on an
eccentric shaft.To change the position of the bearing
(E), loosen the screw (F)Fig. 29 and rotate the shaft
(G) Fig 30 until the blade properly overlaps the
support bearing. Tighten screw (F)Fig. 29.

counterclockwise.
4. Remove table alignment screw (F) Fig. 37.
5. Slip the blade off both wheels and guide it out
through the slot in the table.
6. Check the new blade to make sure that the teeth will
point down toward the table when installed, iF NOT,
CAREFULLY TURN THE BLADE iNSiDE OUT.
7. Place the new blade onto wheels and adjust the
blade tension, blade guides, and tracking as
described previously in this manual.
8. Replace the blade guard, removed in STEP 2), and
the table alignment screw (removed in STEP 4).
Tighten both securely.

Always make sure the upper blade guard
is installed and properly adjusted before operating the
band saw.
9. Close the doors (B) Fig. 35 before operating saw.
10. To use the miter gage as shown in Fig. 40, insertthe
miter gage guide bar into miter gage slot (S) Fig. 37
and adjust it to the desired angle.
DUST PORT
A dust port (A) Fig. 38, is provided to connect your band
saw to a standard shop vacuum or dust collector. The
opening of the dust port is 2-1/4" I.D.

Before starting the machine, see that all adjustments are properly made and the guards are in place. Turn the upper
wheel by hand to make sure that everything is correct BEFORE turning on the power.
Keep the top guide within 1/8" of the work piece at all times. Do not force the material against the blade. Light pressure
on the work piece will produce a smoother cut, and prevent excess friction, heating, and hardening of the blade.
KEEP THE SAW BLADE SHARP. Very little forward pressure is required for normal cutting. Keep the workpiece mov-
ing at a slow and consistent rate against the blade to ensure a smooth and accurate cut.
Avoid twisting the blade by trying to turn sharp corners. Remember, you must saw around corners.
CUTTING CURVES
When cutting curves, turn the stock carefully so that the blade follows without twisting. If a curve is so abrupt that it is
necessary to repeatedly back up and cut a new kerf, a narrower blade, a blade with more set, or additional relief cuts
Fig. 39, may be necessary to allow the blade to cut more efficiently. The more set a blade has, the easier it will allow the
stock to be turned, but the cut is usually rougher than where a medium amount of set is used.
When withdrawing the piece being cut, changing the cut, or for any other reason, be careful not to accidentally draw
the blade off the wheels. In most cases, it is easier and safer to turn the stock and saw out through the waste material,
rather than try to withdraw the stock from the blade.

BAND SAW BLADES
A band saw blade is a delicate piece of steel that is subjected to tremendous strain. You can ob-
tain long use from a band saw blade if you use it properly. Use blades of proper thickness, width
and temper for the various types of material and cuts.
Always use the widest blade possible. Use narrow blades only for sawing small, abrupt curves
and for fine, delicate work. This will save blades and will produce better cuts. For cutting wood
and similar materials, Delta offers blades in widths of 1/8", 1/4", and 3/8".
Any one of a number of conditions may cause a band saw blade to break. Blade breakage is, in
some cases, unavoidable, being the natural result of the peculiar stresses to which blades are
subjected. Blades will break often due to avoidable causes, such as the lack of care to the blade
or the blade not being properly adjusted to the band saw. The most common causes of blade
breakage are:
(1) faulty alignments and adjustments of the guides.
(2) forcing or twisting a wide blade around a curve of short radius.
(3) feeding the work piece too fast into the blade.
(4) dullness of the teeth, or absence of sufficient set.
(5) improperly tensioned blade.
(6) top guide set too high above the work piece being cut.
(7) using a blade with a lumpy or improperly finished braze or weld.
(8) continuous running of the saw blade when not cutting.
Use blades that are 721/2'' in length on this machine.
Always use a sharp blade. Keep it free from gum and pitch. Clean frequently with a stiff fiber
brush.
Narrow blades are used for cutting small circles or curves while the wider blades are best suited
for straight cutting such as ripping.
A new blade, in most cases, will perform better and last longer than a re-sharpened blade.
Insure that the blade guides are adjusted properly.
Do not force or twist the blade around a curve or a very short radius.
Feed the workpiece through the blade at a consistent rate, allow the blade to do the cutting - do
not feed the work piece too fast.
Do not apply excessive tension to the blade. The tension is only necessary to drive the blade
without slipping on the wheels. Narrow blades require less tension than wider blades.
