Remove all crating and plastic from around the
band saw. Remove any lag screws or holding
straps which secure the b and saw to the wood
pallet.
Remove the eye bolt from the tool box, and
screw it into the ho le at the top of the m achine.
Use a forklift with a stra p or chain connected to
the eye bolt to lift the band saw from the pallet.
Move the band saw to its permanent location
which should be dry, well ventilated, with
sufficient lighting. Leave enough space on all
sides to handle long stock or perform routine
maintenance on the machine. Make sure the
floor is level and able to support the weight of
the machine.
The Band Saw may be further stabilized by
securing it to the floor usin g lag screws through
the four holes in the stand.
Areas of the Band Saw have been given a
protective coating at the f actory. This should be
removed with a soft cloth moistened with
kerosene or miner al spirits. Do not get s olvents
near plastic or r ubber parts, and do not us e an
abrasive pad as it may scratch metal surfaces.

Grounding Instructions
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
This machine must be grounded. In the ev ent of
a malfunction or br eakdo wn, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
Improper connection of the equipmentgrounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipmentgrounding conductor. If repair or r eplacem ent 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 tool is properly grounded.
Repair or replace a damaged or worn cord
immediately.
Make sure the voltage of your power supply
matches the specif ications on t he motor plate of
the Band Saw. The machine should be
connected to a dedicated circuit.

The use of an extension cord is not
recommended for this Band Saw. But if one is
necessary, mak e sure the cor d rating is s uitable
for the amperage listed on the machine’s motor
plate. An undersized cord will cause a drop in
line voltage resulting in loss of power and
overheating.
Use the chart in Figure 4 as a gener al guide in
choosing the correct size cord. If in doubt, use
the next heavier ga uge. The smaller the gauge
number, the heavier the cord.
230 Volt, Three Phase Operation
The three-phase m odel is factory wired for 230
volt, but can be converted to 460 volt if so
desired (see “C onverting From 230 Volt t o 460
Volt”). You may either install a plug or “hardwire” the Band Saw directly to a control panel.
If you are connecting a plug, use a proper ULlisted plug suitable for 230 volt operation.

If the Band Sa w is to be hard-wir ed to a panel,
make sure a disconnect is available for the
operator. During hard-wiring of the Band Saw,
make sure the fus es have been removed or the
breakers have been tripped in the circuit to
which the Band Saw will b e connected. Place a
warning placard on the fuse holder or circuit
breaker to prevent it being turned on while the
machine is being wired.
Converting from 230 Volt to 460 Volt
(Three Phase)
To convert from 230 volt to 460 volt:
1. In the band s aw’s electric al box, change t he
setting on the dial of the overload relay
(“FR” on page 42).
2. All re-wiring is done in the electrical box
only, by moving the j umpers at the terminal
block. Re-connect jumpers from 230V to
460V positions as shown in the diagram
inside the electrical box. (The diagram is
also included in the back of this manual.)
3. If using a plug, install a proper UL-listed
plug suitable for 460 volt operation.
IMPORTANT: Consult the diagrams on pages
40-42 for any clarification of these changes on
230V to 460V conversion.
Three-Phase Test Run
After wiring the band s a w, you sh ould check that
the wires have been connected properly.
Connect machine to the p ower source and turn
it on for an instant to watch the direction of blade
movement.
If the blade runs upward instead of downward,
disconnect machine from power, and switch
any two of the three leads in the motor junction
box (see “Electrical Connections”, page 40).
Adjustments
Blade Removal and Installation
Wear leather gloves when
removing or installing band saw blades. New
blades usually come in a coiled position; to
prevent injury, hold the blade with one hand
while carefully uncoiling it with the other.
1. Disconnect machine from power source.
2. Open the u pper and lower doors, and s wing
away the guard (Figure 5).
3. Rem ove th e block f rom the front ed ge of the
table (Figure 5).
11
Figure 5
Page 12
4. Loosen tension on the blade b y turning the
tension handwheel (Figure 6) to the left.
5. Remove the worn b lade and install the ne w
blade, making sur e th e t eet h f ac e do wnwar d
where they pass through the slot in the
table.
6. Use the tension handwheel to tighten the
tension on the blade.
7. Proceed with “Blade Tension” and “Blade
Tracking” before operating the band saw.
Blade Tension
Rotate blade tension handwheel to the right to
increase tension on the blade, to the left to
decrease tension on the blade. Initially, set the
blade tension to corres pond to the width of your
blade, as indicated on t he tens ion gau ge (Fig ure
6). As you become familiar with the saw, you
may find it necessary to change the blade
tension from the initial setti ng, depen ding on the
width of the blade as well as the m aterial being
worked.
Keep in mind that too much or too little blade
tension can cause blade breakage and/or poor
cutting performance.
If the band saw is not to b e used for a period of
time, release tension on the blade – this will
prolong its lif e. First mak e a note of the spec ific
tension setting for that blade. The tension can
then be re-establis hed quickly when operations
are resumed.
Blade Tracking
1. Disconnect machine from power source.
Figure 6
2. Open the top blade wheel doors.
3. Move the gear shift lever into neutral
position (straight down).
4. Move the upper and lower blade guides
away from the blade (see “Blade Guides”).
5. Rotate upper blade wheel by hand,
observing the position of the blade as it
rides upon the wheel. The blade should
track as near the center of the wheel as
possible.
6. If the blade does not track properly, rotate
the blade tracking k nob (Figure 6) clock wise
to move the blade toward the front of the
wheel (as viewed from the front of the saw)
or counterclockwise to move the blade
toward the rear of the wheel. NOTE: This
will also move the blade away from or
toward the stoppers on the blade guide
assemblies, as shown in Figure 7.
12
Figure 7
Page 13
IMPORTANT: These are sensitive
adjustments; make them gradually and
allow the blade time to react to the changes.
7. When satisfied, return the upper and lower
blade guides close to the blade.
8. Close upper and lower doors.
Guide Post
For effective cutt ing and for s afety’s sake, there
should be a minimum am ount of space between
the top of the workpiec e and the bottom of the
blade guides. Loosen the locking knob (see
Figure 6) and rotate the hand wheel (Figure 6) to
raise or lower the guide post so th at the guides
clear the workpiece by about 3/16”.
Blade Guides
Blade guides must be
properly adjusted or damage may occur to
the blade and/or guides.
1. Loosen the two sock et head cap screws on
the guide housing. See Figure 8.
Figure 8
2. Move the guide support forward or
backward in accordance with the width of
the blade. The front e nd of the blade guides
should be adjusted approximately 1/8”
behind the blade teeth. See Figure 8.
3. Tighten the hex cap screws securely.
4. This procedure should be done for both
upper and lower guide housings.
5. Loosen the soc ket head ca p screws (Fig ure
9) on the blade guides.
6. Move the blade guides so t hey are as close
to the blade as possible without touching it.
7. Tighten the sock et head cap screws (Figur e
9).
8. This procedure should be done for both
upper and lower blade guides.
As the blade guides receive use, they will
become worn at the front end. If the blade
guides become dif ficult to adjust, switch the l eft
and right blade guides (Figure 10).
The stopper positioned behind the back edge of
the blade (Figure 10) will als o become worn with
use, and the friction of the shaft with the saw
blade may cause lines in the surface of the
stopper. If this occurs, loosen the socket head
cap screw, and rotate the stopper to either side
to change its position on the blade. Re-tighten
socket head cap screw.

Squaring Work Table with Blade
1. Plac e the table in hori zonta l pos ition with “ 0”
on the scale (Figure 11).
2. Place a m achinist’s square on the ta ble and
against the blade as shown.
3. If the square is not flush against the blade,
loosen the screw belo w the tabl e ( Figur e 1 1)
with a 26mm wrench (provided).
4. Tilt the table as needed until the square is
flush with blade. Retighten the screw.
5. Make sure the pointer is set at “0” on the
scale. If it needs slight adjustment, loosen
the screw and sh ift the pointer u ntil it aligns
with “0”. Re-tighten the screw.
Auxiliary Table
1. After the main work table has been set
perpendicular to the blade, use a straight
edge to confirm that the auxiliary table is
level with the m ain t able, as shown in F igure
12. If the auxiliary table is not level with the
main table, make adjustments as follows.
2. To tilt the auxiliary table lef t or right, loosen
the screws (A, Figure 12) and turn one of
the stops (B, Figure 12) as needed. Retighten screws (A, F igure 12) securely after
adjustment.
3. To adjust the table front to back, loosen
screws (C, Figure 12). Re-tighten screws
securely after adjustment.
Replacing Drive Belts
(See Figure 13)
Figure 11
Figure 12
1. Disconnect machine from power source.
2. T o rem ove t he motor drive belt, loosen the
four screws at the base of the m otor. Lift up
on the motor to slacken and remove the
belt.
3. To remove the air compressor drive belt,
loosen the four hex nuts on the base of the
air compressor and slide the compressor in
the direction of the motor. After installing a
new belt, slide the compressor away from
the motor to tension the belt, and re-t ighten
the four hex nuts.
4. To r emove the gearbox drive belt, lo osen
the hex nuts on the base of the lower
variator, and slide the lo wer variator upwar d
to slacken and remove the belt.
5. To remove the variator belt, loosen the four

bulb.
Band Saw Operation
Consult “Features an d Terminology” on page 7
for identification of the controls.
Unlock the control panel using the provided
keys.
Never operate the band saw
without blade covers in place and secured.
Blade Break-In Procedure
New blades are very shar p and, therefore, h ave
a tooth geometry that is easily damaged if a
careful break-in procedure is not followed.
Consult the blade manufacturer’s literature for
break-in of specif ic blades on spec ific materials .
The following procedure will be adequate,
however, for break -in of JET -supplied blades on
lower alloy ferrous materials.
1. Use a section of round stock.
2. Operate the saw at lo w speed. Start the cut
with a very light feed rate.
3. When the saw has completed about 1/3 of
the cut, increase the feed rate slightly and
allow the saw to complete the cut.
4. Keep the feed rate at the same setting a nd
begin a second cut on the same or similar
workpiece.
5. When the saw has completed about 1/3 of
the cut, increase the feed rate while
watching the chip f or mation until cutting is at
its most efficient rate (refer to “Evaluating
Cutting Efficiency” below). Al low the saw to
complete the cut.
6. The blade is now considered ready for use.
Setting Blade Speed
1. Ref er to the Speed and P itch s election c hart
on page 23. Select t he speed sett ing for the
material to be cut.
2. While the machine is NOT running, move
the gear shift lever to the required speed
setting (high or low). See Figure 14.
Move the gear shift lever
only when the machine is NOT running, to
prevent damage to the gearbox.
15
Figure 14
Page 16
3. Start the saw using the pushbutton.
4. Turn the speed setting handwheel (Figure
14) to the required speed. Turning the
handwheel clockwise increases speed.
Turning counterclockwise decreases speed.
Rotate the speed setting
handwheel only when the band saw is
running.
Evaluating Cutting Efficiency
The best way to d etermine whet her the blade is
cutting efficientl y is to observe t he chips form ed
by the cutting.
• If the chip formation is powdery, then the
feed is much too light, or the blade is dull.
• If the chips f ormed are curled, but co lored –
blue or straw colored from heat generated
during the cut – then the feed rate is too
high.
• If the chips are slightly curled and are not
colored by heat – the blade is sufficiently
sharp and is cutting at its most efficient rate.
Welder Operation
Wear eye protection while
operating the welder. Use care when
handling the blade after welding to avoid
burns.
The welding procedure involves the following
steps: Shearing the blade, grinding teeth to
allow for the weld area, the actual welding,
inspection of the blad e, annealing, grindin g and
a final inspection of the blade. This procedure
can be accomplished using the shear and
welder assemblies on your band saw. Proceed
as follows:
Shearing
Cut the blade to the longest length needed for
the band saw. Using t he sh ear to cut your blad e
will ensure that the blade ends are cut flat,
square and smooth.
1. Place the blade in the shear as shown in
Figure 15. Make sure the blade is held
square with the shear k nife, so that the cut
will be square with the blade.
Figure 15
2. Position the blad e so that t he cut is m ade at
a place that allows for uniform spacing of
the teeth. See Figure 16.
3. Push down the handle.
16
Figure 16
Page 17
IMPORTANT: If a bla de has been cut by using
snips, the ends of the blade must be ground
square before welding them together, as shown
in Figure 17.
Removing Teeth
In fine pitched blades, one or more of the teeth
on each side of the c ut may need to be removed
by grinding so that the weld area of the blade is
uniform and the teeth will be uniformly spaced.
See Figure 16.
Welding
4. Carefully clean the ends of the blade which
will contact the welder jaws. Remove any
dirt, oil, scale and oxide.
Any rust (oxide) on th e blade
in the vicinity of the weld must be ground off
before the blade can be welded.
5. Turn pressure knob to “0” position (pointed
downward). NOTE: There will be some
resistance when turning the knob.
6. Insert one end of the blade in the left clam p
(Figure 18). Position the back edge of the
blade against the back edge of the left
clamp. Then position the end of the blade
midway between the left and right clamps.
Tighten the left clamp.
7. Insert the other end of the blade in the right
clamp. Position the back edge of the blade
against the back of the right clamp. Then
butt the end of the blade against the other
end of the blade (the blade ends need to be
in contact with eac h other). Tighten th e right
clamp.
8. Set the pressure selector switch
(counterclockwise rotation) to the
approximate setting require d for the width of
the blade being welded.
Figure 17
Figure 18
Keep hands clear of the w eld
area and the clamp jaws during welding.
9. Press and hold the weld b utton (Figure 18).
When the weld button is pushed, the left
clamp moves to the right to app ly pressure
to the blade ends. At the same tim e, sparks
will come from the blade ends as they are
being welded. Do not release weld button
until the blade joint is “red hot.”
10. Release the weld button, and wait 3 or 4
seconds until blad e returns to orig inal color.
Unclamp the blade.
11. Rotate the pressure selector switch back to
“0”.
17
Page 18
The welder is designed for
intermittent use. Repeated welding within a
short period of time may cause the welder to
overheat.
12. Remove the blade from the clamps, and
carefully inspect it. T he spacing of the te eth
should be uniform and the weld should be
located in the center of the gullet.
Misalignment is easily noted at this time
from the weld appearance. See Figure 19
for examples of incorrect welds.
13. If the weld is imperfect, refer to the troubleshooting section on page 28 for possible
remedies to any probl ems. Make corrections
before annealing.
Annealing
The blade must no w be an nea led, or c o ole d a t a
controlled rate to prevent it from becoming too
brittle.
14. T urn the pressure sele ctor knob all the way
to the left so the clam p jaws are closest to
each other.
15. Insert the bla de into the cl amps so the weld
area is centered between the clamps.
Secure the blade in t he jaws with th e clamp
handles.
Figure 19
16. Quickly press and release (jog) the anneal
button (Figure 18). Repeat the press-andrelease process until you see a slightly red
glow from the weld area.
Do not press and hold the
anneal push button. The weld will be
overheated and will fail due to the excessive
heat.
17. Release both blade clamps, allow the blade
to cool, then remove the blade from the
clamps.
18. Check the integrity of the weld. Bend the
blade to form a radius at the point of the
weld. The size of the radius should be
approximately the sam e as the radius of the
band saw drive wheel. T he weld must hold
and not break or crack after forming the
radius. If the weld breaks, cut away the
welded area and repeat the weldingannealing process.
19. Check to make sure the welded section is
the same thicknes s as the rest of the blade.
If not, grind off excess weld material using
the grinder (Figure 20). Figure 21 illustr ates
some unacceptable grindings.
Figure 20
Figure 21
18
Page 19
If the blade is thicker at the
weld than at the rest o f the blade, using the
blade may damage the guides.
20. When grind ing, do not hit the teeth, or grind
deeper than the thickness of the blade; or
burn or overheat the weld area. Be sur e to
remove flash from the back edge of the
blade. Any flash or “stub” teeth which
project beyond the normal set or height of
the other teeth must be ground off.
Clean Up
It is very important th at the clamp jaws be kept
clean at all times. The jaws or inserts m ust be
wiped or scraped clea n after every weld. Doing
this will ensure better welds by holding proper
alignment, preventing flash from becoming
embedded in the blade, and preventing shorts or
poor electrical contact.
Blade Selection
Using the proper bl ade for the job will increase
the operating eff iciency of your band saw, help
reduce necessary saw maintenance, and
improve your producti vity. Thus, it is important to
follow certain guidelines when selecting a saw
blade. Blade breakage, te eth stripping, crooked
cuts, and other comm on com plaints are, in most
instances, caused by using the wrong blade.
Consider these factors when selecting a blade:
• The type of material you will be cutting.
• The thickness of the workpiece.
• The features of the workpiece, such as
bends or curves with small radii.
These factors are important because they
involve basic concepts of saw blade design.
There are six blade features that are normally
changed to meet certain sawing requirements:
1. width
2. gage
3. pitch (number of teeth per inch)
4. tooth form (or shape)
5. the “set” of the teeth
6. the blade material itself
Width
Band saw width is measured from the back of
the blade to the tip of the tooth. Al ways use the
widest blade possible that still performs the
needed job. Generally, wider blades are used
for straight cutting. Narrower blades are used
when the part being cut has curves with small
radii. Refer to the c hart in Figure 22 to select a
width for radius cutting.
The radii in this chart are all based on cutting 1-inch thick
mild steel and using manual feed. In order to cut a close
tolerance radius the following factors, in addition to the blade
width, must be considered: thickness, machinability, feed
force and the location of the pivot point. Heavy feed in thick
work, for example, results in a barrel-shaped cut.
Figure 22
19
Page 20
Gage
Use the standard gage (b lade thick ness) except
when the increased thickness of the workpiece
decreases accuracy and width cannot be
increased to compensate.
Examples of heavy gage applications:
1. When radius cutting in thick materials.
2. When the maximum width usable on the
machine still provides insufficient beam
strength for the blade. (Bea m strength is the
blade’s resistance to compression caused
by strong feeding or the type of material
being cut).
Pitch
Pitch is measured in “teeth per inch” (T .P.I.) and
can be constant or variable. Figure 23 shows
blades with diff erent pitches. A fine pitch (m ore
teeth per inch) will cut slower but smoother. A
coarse pitch (fewer teeth per inch) will cut
rougher but faster.
As a rule of thumb, the thicker the workpiece,
the coarser will be t he bla d e pi tch. If you have to
cut a hard or very brittle material, you will
probably want to use a blade with a finer pitch in
order to get clean cuts.
Using a blade with too few teeth may cause
vibration and a rou gh cut, while too m any teeth
may cause the gullets to fill with shavings and
overheat the blade.
As a general rule, use a b lade that will have no
fewer than 6 and no m ore than 12 teeth in the
workpiece at any given time.
The chart on page 23 will aid in determining
pitch for a particular job.
Shape
Figure 23
Figure 24 shows com mon types of tooth s hape.
Tooth shape has an effect on cutting rate.
The Regular blade, sometimes called a “raker”
blade, has evenly spaced teeth that are the
same size as the gullets, and a 0-degree rake
angle. This is a good general-purpose blade,
and often works well with ferrous metals .
The Skip type has f ewer t e eth an d l ar ger gu ll ets ,
providing the added chip clearance needed for
cutting softer, nonferrous materials, as well as
non-metallic applic ations such as wood, plastic ,
cork, and composition materials.
The Hook blade has lar ger teeth and gullets and
a positive rake ang le which permits better feed
and chip rem oval. It is useful for bot h cast iron
as well as hard, nonferrous alloys.
20
Figure 24
Page 21
Variable-tooth blades combine features of the
other styles. They generally offer smooth cuts
and long blade life, while reducing noise and
vibration.
Set
The term “set” refers to the way in which the
saw teeth are bent or positioned. Bending the
teeth creates a kerf that is wider than the back
of the blade.
Set patterns are usually selected depending
upon the type of m aterial that needs to be cut.
Three common set patter ns are s hown in Figure
25.
The Regular, or Raker, set is generally furnished
on blades which have 2 to 24 teeth per inch.
These blades have o ne tooth set to left, one to
right, and one unset tooth called a raker. The
raker set is often used for contour cutting.
The Wave set is generally furnished on blades
which have 8 to 32 teeth per inc h. This set has
groups of teeth bent alt ernately to left and r ight,
which reduces the strain on individual teeth.
Blades with a wave set are used where tooth
breakage is a problem, such as in cutting thin
stock or where a variety of work is cut without
changing blades; also when the thick ness of the
workpiece changes, such as cutting hollow
tubing or structurals.
The Straight set has teeth in a consistent,
alternating pattern, which is good for fast, basic
cuts where a fine finish is not im por tant. This set
is also popular for cutting wood and plastic s .
Material
Some of the most common blade materials
include:
Carbon Steel Blade – widely used because of
its general adaptabil ity for all types of work and
for its lower cost. Excellent for cutting
nonferrous metals and plastics.
High Speed Steel Blade – resists heat
generated while cutting to a far greater extent
than carbon steel blades. Best suited for cutting
nonferrous metals.
Figure 25
Blade Breakage
Band saw blades are subject to high stresses
and breakage may sometimes be unavoidable.
However, man y factors can be c ontroll ed to help
prevent most blade breakage. Here are some
common causes for breakage:
1. Misalignment of the blade guides.
2. Feeding workpiece too quickly.
3. Using a wide blade to cut a short radius
curve.
4. Excessive tension.
5. Teeth are dull or improperly set.
6. Upper guides are set too high off the
workpiece.
7. Faulty weld on blade.
Carbide-Tipped Blade – Best used for cutting
titanium, beryllium, and case hardened
materials.

Maintenance
Before doing maintenance on
the machine, disconn ect it from th e electri cal
supply by pulling out the plug or switching
off the main switch ! Failure to compl y may
cause serious injury.
Use a brush to loosen accumulated chips and
debris. Use a shop vacuum to remove the
debris. Make sure the chip brush on the lower
band wheel is properly adju st ed.
Lubricate the air compressor with air tool oil
about every six months, or more frequently if
necessary. Unscrew the cap (Figure 26) and
add oil. Replace cap when finished.
Add grease to the gear box through the grease
fitting; also add gr ease as needed to the worm
gear.
If the power cord is worn, cut, or damaged in
any way, have it replaced immediately.
Figure 26
The chart (Figure 27) identifies areas that
require cleaning and/or lubricating. Use good

machine to cool down before restart.
Allow unit to adequately cool before
attempting restart. If problem persists,
check amp setting on the motor

One cause of overloading trips which
are not electrical in nature is too
heavy a cut. The solution is to reduce
feed pressure into the blade. If too
heavy a cut is not the problem, then
check the amp setting on the overload
relay. Match the full load amps on the
motor as noted on the motor plate. If
amp setting is correct then there is
probably a loose electrical lead.
Check amp setting on motor starter.
Verify that band saw is on a circuit of
