CONNECTING BAND SAW TO POWERSOURCE
POWERCONNECTIONS
A s e p arate electrical circuit should be used for your tools. This circuit should not be less than #12
wire and should be protected with a 20 Amp fuse. Have a certified electrician replace or rep air a
worn cord immediately. Before connecting the motor to a power line, make sure the switch is in
the OFF position and be sure that the electric current is of the same characteristics as st amped
on the motor nameplate. Running on low volt age will damage the motor .
W ARNING:D O NOT EXPOSE THE TOOL TO RAIN O R OPERATE THE TOOL IN DAMP

CAUTION: IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.
IF Y O U A R E N O T SURE, H AVE A CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.
This tool is intended for use on a circuit that has an outlet
and a plug that looks like the one shown in Fig. 30. A
temporary adapter, which looks like the adapter illustrated
in Fig. 31, may be used to connect this plug to a 2-pole
recept acle, as shown in Fig. 31, if a properly grounded
outlet is not available. The temporary adapter should be
used only until a properly grounded outlet can be inst alled by a qualified electrician. THIS ADAPTER IS
N O T APPLICABLE IN CANADA. 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, as shown in Fig. 31.
GROUNDING INSTRUCTIONS
CAUTION: THIS TO O L MUST BE GROUNDED WHILE IN US E
TO PROTECT THE OPERATO R FROM ELECTRIC SHOCK.
In the event of a malfunction or breakdown, grounding
provides a p ath of least resist ance for electric
current to reduce the risk of electric shock. The motor is
equipped with an electric cord having an equipmentgrounding conductor and a grounding plug. The plug
must be plugged into a matching outlet that is properly
inst alled 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 inst alled 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 conduc tor. If rep air or replacement of the electric cord or plug is
necessary, do not connect the equipment grounding con ductor to a live terminal.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely under stood, or if in doubt as to whether the tool is properly
grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and 3-hole recept acles that accept
the tool s plug, as shown in Fig. 30.
R e pair or replace damaged or worn cord immediately.
GROUNDING BLADE IS

CORDIN FEET CORDTO USE
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 a 3-hole
recept acle which will accept the tool s plug. When using
an extension cord, be sure to use one heavy enough to
carry the current of the band saw. An undersized cord will
cause a drop in line volt age resulting in loss of power and
overheating. Fig. 32 shows the correct size to use depending on cord length. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the cord.

IMPORTANT:Before tracking the blade, make sure the
blade guides and blade support bearings are clear of the
blade so as not to interfere with the tracking adjustment.
Af ter tension has been applied to the blade, revolve the
wheels slowly forward by hand and watch the blade (A)
Fig. 41, to see that it travels in the center of the upper
tire. If the blade begins to creep toward the front edge,
loosen the wing nut (B) Fig. 42, and tighten the thumb
screw (C). This will tilt the top of the wheel toward the
back of the machine and will draw the blade toward the
center of the tire. If the blade creep s toward the back
edge, turn the thumb screw in the opposite direction.
Adjust the thumb screw (C) Fig. 42, only a fraction of a
turn at a time. NEVER TRACK THE BLADE WHILE
THE MACHINE IS RUNNING. Af ter the blade is tracking
in the center of the tires, tighten the wing nut (B) Fig. 42.
ADJUSTING
BLADE TENSION
DISCONNECT MACHINE FROM POWER SOURCE.
On the back of the upper wheel slide bracket, there is a
series of graduations. These indicate the proper tension
for various wid ths of blades. W ith the blade on the
wheels, turn the knob (A) Fig. 40, to raise or lower the
wheel, until the red fiber washer (B) is in line with the
proper graduation for the size of blade being used.
The graduations will be found correct for average work,
and are not af fected by rebrazing of the saw blade. W e
urge you to use these graduations until you have
become familiar enough with the operation of the Band
Saw to vary the tension for dif ferent kinds of blades or
work. Over-straining is a common cause of blade break age and other unsatisfactory blade performance. Release the tension when the machine is not in use.

ADJUSTING UPPER BLADE
GUIDES AND BLADE
SUPPORT BEARING
DISCONNECT MACHINE FROMPOWER SOURCE.
The upper blade guides and blade support bearings are
adjusted only af ter the blade is tensioned and tracking
properly. To adjust proceed as follows:
1. The upper blade guides (A) Fig. 45, are held in place
by means of the set screws (B). Loosen the set screws
(B) to move the guides (A) as close as possible to the
side of the blade, being careful not to pinch the blade.
Then tighten the screws (B).
2. The guides (A) Fig. 45, should then be adjusted so
that the front edge of the guides are just behind the
gullet s o f the saw teeth. The complete guide block
bracket can be moved in or out by loosening thumb
screw (C) and turning knurled knob (D) Fig. 45. When
guides (A) are set properly, tighten thumb screw (C).
3. The upper blade support bearing (E) Fig. 45, pre vent s the blade from being pushed too far to the rear
which could damage the set in the saw teeth. The sup port bearing (E) should be set 1/64 behind the blade by
loosening thumb screw (F) and turning knurled knob (G)
to move the support bearing (E) in or out.
4. The blade support bearing (E) should also be adjust ed so the back edge of the blade overlap s the out side
diameter of the ball bearing by about 1/16 . The bearing
(E) is set on an eccentric and to change position remove
screw (H) and bearing (E) Fig. 45. Loosen thumb screw
(F), back out screw (G) and re-position shaf t that bearing
(E) is att ached to.

The upper blade guide assembly (A) Fig. 43, should
always be set as close as possible to the top surface of
the material being cut by loosening lock knob (B) a nd
moving the guide assembly (A) to the desired position.
The upper blade guide assembly should also be adjust ed so that the blade guides (A) Fig. 44, are flat with the
blade. If an adjustment is necessary, loosen screw (B)
and rot ate the complete guide assembly (C) until the
blade guides are flat with the blade.

The lower blade guides and blade support bearing
should be adjusted at the same time as the upper guides
and bearing as follows:
1. Loosen the two screws (A) Fig. 46, and move the guides
(B) as close as possible to the side of the blade, being care ful not to pinch the blade. Then tighten screws (A).
2. The front edge of the guide blocks (B) should be adjust ed so they are just behind the gullets of the saw teeth
by turning the knurled knob (C) Fig. 46.
3. The lower blade support bearing (D) Fig. 46, should
be adjusted so it is about 1/64 behind the back of the
blade by turning the knurled knob (E).

BAND SAW BLADES
A band saw blade is a delicate piece of steel that is sub jected to tremendous strain. Y ou can obt ain long use
from a band saw blade if you give it fair treatment. B
ensure you use blades of the proper thickness, wid th,
and temper for the various types of material to be cut.
Always use the widest blade possible. Use the narrow
blades only for sawing small, abrupt curves and for fine
delicate work. This will save blades and will produce
better work. Band saw blades may be purchased, welded, set and sharpened ready for use. For cutting wood
and similar materials, we can supply them in wid ths of
1/8, 3/16, 1/4, 3/8, 1/2, and 3/4 inches.
File and set the wood cutting blades whenever you find it
requires pressure to make them cut. If a blade is broken
it can be brazed or welded; however, if it has become
badly work-hardened, it will soon break in another place.
If you are not equipped to file, set and braze or weld
blades, t ake them to a saw filer for reconditioning. Under
average conditions, blades should be resharpened af ter
4 hours of operation.
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 such blades are subjected. It is, how ever, of ten due to avoidable causes, most of ten to lack of
care or judgment on the p art of the operator in mounting
or adjusting the blade or guides. The most common
causes of blade breakage are: (1) faulty alignment s and
adjustments of the guides; (2) forcing or twisting a wide
blade around a curve of short radius; (3) feeding too fast;
4) dullness of the teeth or absence of suf ficient set;
(5) excessive tightening of the blade; (6) top guide set
too high above the work being cut; (7) using a blade with
a lumpy or improperly finished braze or weld; and (8)
continuous running of the saw blade when not in use for
cutting.
New blades for the st andard 14-inch Band Saw are
93-1/2 inches long. The adjustment will accommodate
blades up to a maximum length of 94 inches and to a
minimum length of 91-1/2 inches. When equipped with
the No. 28-984 Height Att achment, new blades should be
105 inches long; maximum and minimum lengths are
106 and 103-1/2 inches.

OPERATING T HE BAND SAW
Before st arting the machine, see that all adjustment s are
properly made and the guards are in place. T urn the
pulley by hand to make sure that everything is correct
BEFORE turning on the power.
Keep the top guide down close to the work at all times.
Do not force the material against the blade too hard.
Light cont act with the blade will permit easier following of
the line and prevent undue friction, heating, and work-
hardening of the blade at it s back edge.
KEEP THE SAW BLADE SHARP and you will find that
very little forward pressure is required for average cut ting. Move the stock against the blade steadily and no
faster than will give an easy cutting movement.
A void twisting the blade by trying to turn sharp corners.
Remember, you must saw around corners.
CUTTING C U RVES
When cutting curves, turn the stock carefully so that the
blade may follow without being twisted. If a curve is so
abrupt that it is necessary to repeatedly back up and cut
a new kerf, either a narrow blade is needed or a blade
with more set is required. The more set a blade has, the
easier it will allow the stock to be turned, but the cut is usu ally rougher than where a medium amount of set is used.
In withdrawing the piece being cut, in order to change the
cut, or for any other reason, the operator must be careful
that he does not accident ally draw the blade of f the
wheels. In most cass 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.

RESAWING OPERATIONS
1. MAKE CERTAIN THE MACHINE IS DISCONNECTED FROMTHE POWER SOURCE.
2. Thread knob (P) Fig. 47, onto 2 long screw (S) and
tighten with a flat-bladed screwdriver .
3.Att ach guide post (O) Fig. 48, to either side of rip
fence assembly (H) with hand knob assembly (P). Position the guide post (O) on the fence assembly so it is
centered with the front edge of the blade. This will pro vide better control while performing intricate cut s.
4. Fig. 49, illustrates a typical resawing operation using
the guide post (O) assembled to the rip fence.
If a number of identically shaped thin pieces are required,
the easiest way to make them is the resawing technique.
In this operation the face of the rip fence can be used, or
to have more control when working with irregular shaped
pieces, a guide post can be used on either side of the
rip fence. T o assemble the guide post to the rip fence,
proceed as follows:
