7.7 Blade tension
Blade tension is set with the blade tension
handwheel (L, Figure 7-10) and is performed
following blade replacement and periodically as the
blade stretches from use.
Disconnect machine from
power source before making any adjustments.
Refer to Figures 7-9 and 7-10.
1. Place tension lever (K, Figure 7-9) in Full Tension position.
2. Set blade tension by rotating handwheel (L)
according to the arrow directions shown in
Figure 7-10, clockwise to tighten,
counterclockwise to loosen.
3. The gauge (M) indicates approximate tension
according to the width of the blade in inches.
Initially, set the blade tension to correspond to
the width of your blade.
As you become familiar with the saw, you may find
it necessary to change the blade tension from the
initial setting.
Keep in mind that too little or too much blade tension
can cause blade breakage and/or poor cutting
performance.
Tip: When the band saw is not being used, place
tension lever to Partial Tension position – this will
prolong the blade’s life.
7.8 Adjusting blade tension lever
The blade tension lever has an adjustment screw or
stop bushing that allows you to adjust how much
tension is released when lever is used.
To adjust tension lever:
1. Disconnect machine from power source.
2. Move lever to Blade Release position and
remove blade.
3. Move tension lever to Full Tension position.
4. Move stop bushing (Figure 7-11) until gap
between stop bushing and wheel shaft hinge is
1/8 to 3/16 in.

7.9 Blade tracking
O
N
P
R
Refer to Figures 7-12 and 7-13.
After proper tensioning, the blade must be tracked.
“Tracking” refers to position of blade on the wheels
while machine is in operation. Tracking should be
checked periodically and is mandatory after every
blade change. Blade tracking is done by hand with
machine disconnected from power.
1. Disconnect machine from power source.
2. Blade must be correctly tensioned (sect. 7.7).
3. Make sure blade guides and other parts of
machine will not interfere with blade movement.
Use handwheel (N) to lower guide post until you
can see blade through tracking window (O,
Figure 7-12).
4. Set blade tension lever initially to Partial Tension-Idle/Tracking position.
8. Loosen locking handle (P, Figure 7-12) and
slightly rotate tracking knob (R) with your right
hand while continuing to rotate wheel with your
left. Observe blade through tracking window.
Rotating knob clockwise will cause blade to
move toward rear edge of wheel. Rotating knob
counterclockwise will cause blade to move
toward front edge of wheel.
IMPORTANT: This adjustment is sensitive;
perform in small increments and give blade time
to react to changes.
9. When blade is tracking in center of wheel, retighten locking handle (P), and close upper
door.
10. Move tension lever to Full Tension position, and
connect band saw to power. Turn it on for a brief
time to observe blade in action through tracking
window.
11. If further adjustments are needed, disconnect
from power and repeat above procedure.
7.10 Overview – bearing adjustments
Thrust (back support) bearings are located behind
saw blade and provide support to back of blade
when saw is in operation.
Guide bearings are located on either side of saw
blade and provide stability for the blade when saw
is in operation. These bearings rotate on an
eccentric shaft so distance from blade can be
adjusted for optimal performance.
Figure 7-12
5. Open upper door to expose wheel.
6. Rotate wheel by hand, observing position of
blade through tracking window. As you rotate
wheel, move tension lever to Full Tension
position. The blade should continue to ride upon

set lever to Partial Tension-Idle/Tracking.
7.11 Upper blade guides
Unplug machine from power
source before making any adjustments! Blade
teeth are sharp – use care when working near
blade. Failure to comply may cause serious
injury.
The bearing guides should be set so that contact
between blade and guides will occur only when
blade is under pressure from a workpiece. To adjust
upper bearing guides for proper blade control,
proceed as follows.
Refer to Figures 7-14 and 7-15.
1. Disconnect machine from power source.
2. Blade must already be tensioned and tracking
correctly. Place tension handle in Full Tension
position.
3. Lower guide post until upper guide bearings are
a few inches off table. (The reason for this will
be evident later in sect. 7.15)
4. Loosen lock knob (A, Figure 7-14).

5. Slide entire guide bracket until front of guide
bearings are about 0.015” (1/64”) behind the
blade’s gullet (curved area at base of tooth).
See Figure 7-16.
Figure 7-16
6. Tighten lock knob (A) to secure this position.
7. Loosen lock knob (B) for either of the front guide
bearings.
8. The guide bearing rotates on an eccentric shaft.
Adjust guide bearing by rotating the knurled
knob (C) until guide bearing is approximately
0.004” from blade. A quick way to achieve this
spacing is by placing a single thickness of a
crisp dollar bill (a dollar bill is approximately
0.004” thick) between blade and guide bearing.
Adjust guide bearing until it just lightly grips the
dollar bill.
NOTE: Do not force guide bearing against side
of blade. It should generally only make contact
with blade when there is pressure from the
cutting operation.
9. Tighten lock knob (B).
10. Repeat process for opposite guide bearing.
7.12 Upper thrust bearing
Refer to Figures 7-14 and 7-15.
The thrust bearing prevents backward deflection of
blade during cutting. A groove in the bearing surface
helps stabilize the moving blade.
1. Loosen lock knob (D) and slide thrust bearing
up to back of blade.
2. Adjust thrust bearing until space between
groove bottom and back edge of blade is
approximately 0.015” (1/64”). Tighten lock knob
(D).
3. If lateral adjustment of bearing is needed to
align groove with blade, loosen set screw (E) at
front of bearing assembly, and shift bearing as
needed. Retighten set screw.
4. Make sure all lock knobs on upper guide
bearing assembly are tightened when
adjustments are finished.
7.13 Lower blade guides
Unplug machine from power
source before making any adjustments! Blade
teeth are sharp - use care when working near
saw blade. Failure to comply may cause serious
injury.
Refer to Figures 7-17 and 7-18.
1. Disconnect band saw from power source.
2. Open lower door and swing lower guard out of
the way.
3. Adjust lower guide bearings and lower thrust
bearing below table in similar manner to that of
upper guide and thrust bearings.
4. Movement summary: Loosen lock knob (F) to
move entire guide bearing assembly. Loosen
lock knob (G) and rotate knob (H) to adjust
guide bearing in relation to blade. Thrust
bearing is controlled by locking knob (J) and
lateral adjustment by set screw (K).
5. Make sure all knobs and handles are tightened
after adjustments are complete.

7.14 Guide post
Refer to Figure 7-19.
1. Disconnect band saw from power source.
2. Loosen lock knob (L) and raise or lower guide
post using handwheel (M).
7.15 Guide post parallelism
The guide post should be parallel to blade
throughout vertical travel of the guide post; thus the
guide bearings will maintain their relationship to
blade at any height from the table and won’t require
re-setting each time guide post is moved. This
setting has been accurately made by the
manufacturer and should not require immediate
attention, but may be checked in future as follows:
1. Disconnect band saw from power source.
2. Move blade tension lever to Full Tension
position.
3. The guide bearings in low position should
already be set in relation to blade (see sect.
7.11). Also, the table must be square with blade
(see sect. 7.4).
4. Loosen lock knob (L, Figure 7-19) and raise
guide post to a high position.
5. Confirm that guide post travels straight up and
down, and guide bearings maintain their
relationship to blade.
6. If guide post does not go straight up and down
(blade begins deflecting when guide post is
raised), slightly loosen the four screws (O) and
turn any combination of the four set screws (P)
as needed to bring guide post into line.
7. When finished adjusting, securely tighten the
four screws (O).
8. Verify the setting by raising and lowering guide
post.
7.16 Brushes
An adjustable brush is located in the lower wheel
housing. It should remain in constant contact lite to
moderate with blade and wheel to prevent buildup
of gum and debris. Loosen screw and adjust as
needed, then retighten screw.
Figure 7-19
3. Position blade guide assembly so that bottom of
guide bearings are about 1/8” above material to
be cut. Or, simply lower guide post until scale
pointer (N) indicates height of your workpiece.
This provides minimal clearance between
workpiece and bottom of guide bearings, which
will minimize blade deflection as well as
enhance operator safety.
4. Tighten lock knob (L).
7.17 Drive Belt Changing,
Replacement, and Tensioning
This band saw is designed to provide blade speeds
which will function for cutting metals and woods.
This functionality thus requires the operational
setting to change with the change of materials.
It is expected that the operator will change the saw
setup to match the material being cut. This will
include the drive belt position, the saw blade, the
display mode setting, and the blade speed.
Disconnect machine from
power source before making any adjustments.
While this procedure is directed toward the normal
changing of the belt position, when the belt(s)
becomes worn, cracked, frayed or glazed, they
should be replaced following these same step using
new belts for the installation steps.
18
Depending on the desired cutting application, this
C A B
D F E
band saw can be set for either “Wood Cutting” mode
with a speed range of 540-3600 SFPM (with wood
working blade installed) or “Metal Cutting” mode
with a speed range of 100-650 SFPM (with metal
working blade installed).
This is done by changing the positioning and
configuration of the belt(s) to match the desired
mode of operation.

4. Open the lower drive wheel door.
Figure 7-24
7. Loosen the lock handle (C, Figure 7-23) and
lower the motor to tighten the vertical drive belt
(C, Figure 7.21).
8. Check tension by pushing with moderate
pressure on the belt halfway between the
pulleys. An adequately tensioned belt will
deflect about 1/2”. If tension is not strong
enough, push down on motor.

intermediate pulley (E, Figure 7.24).
5. Install the short Poly V-Belt A28 (D, Figure 7-
24) into the outboard grooves of the
intermediate and motor pullies.
6. Turn the handwheel (A, Figure 7-23) to tighten
the drive belts (D, Figure 7.21). This will pull the
intermediate pulley (B, Figure 7-23) outboard.
7. Check tension by pushing with moderate
pressure on the belt halfway between the
pulleys. An adequately tensioned belt will
deflect about 1/2”. If tension is not strong
enough, turn the handwheel ½ to 1 turn at a
time to gain the correct tension.
8. When complete, the belt routing will match
Figure 7.21 and the rotation indicator (E, Figure
7-22) will rotate when the saw is operating.
9. Complete the change to “Metal Mode” by
installing the correct blade and changing the
display to Metal Mode.
Note: If one belt is used more than the other belt, it
will stretch lightly under normal conditions that
means one belt may be looser than other when both
belts are installed. This is normal.
Overtightening the belt will decrease the lifespan of
bearing in the pulley.

Consult section 8.0 for identification of the controls.
Never operate band saw without blade and wheel
covers in place and secured.
The following section contains basic information and
is not intended to cover all possible applications or
techniques using the band saw. Consult published
sources of information, acquire formal training,
and/or talk to experienced band saw users to gain
proficiency and knowledge of band saw operations.
(The following figures may or may not show your
specific band saw, but procedures are the same.)

1. Press the “Selection” button (G, Figure 8-1).
The corresponding mode “ Wood” LED (F,
Figure 8-1) will light up when selected.
8.2.2 Metal Cutting Operation
Before starting the machine, make
sure the belt C & D are installed as shown as
Figure 8-3
Figure 8-3 – Belt Position for Metal
1. Press the “Selection” button (G, Figure 8-1).
The corresponding mode “ Metal” LED (E,
Figure 8-1) will light up when selected.
2. The disc (E) Figure 8-3 must spin during the
operation.
9.1 General Procedure
1. Setup the saw to match the specific material to
be cut. “Wood Mode” for wood or “Metal Mode”
for metal.
2. Install the proper blade for use with the material
to be cut.
3. Make sure the blade and upper and lower
bearings are properly adjusted for tension and
tracking.
4. Adjust blade guide assembly so that the guide
bearings are just above workpiece (about 3/16”)
allowing minimum exposure to blade. See
Figure 9-1.
Figure 9-1
5. If using the fence, move it into position and lock
it to the guide rail. If you are using the miter
gauge for a crosscut, the fence should be
moved safely out of the way.
21
6. Turn on band saw and allow a few seconds for
the machine to reach full speed.
Whenever possible, use a push
stick, hold-down, power feeder, jig, or similar
device while feeding stock, to prevent your
hands getting too close to the blade.
7. Place the straightest edge of the workpiece
against the fence and push the workpiece
slowly into the blade. Do not force the
workpiece into the blade.
When cutting, do not overfeed
the blade; overfeeding will reduce blade life and
may cause the blade to break.
8. When cutting long stock, the operator should
use roller stands, support tables, or an assistant
to help stabilize the workpiece.
9.2 Ripping
Ripping is cutting lengthwise through the workpiece,
and with the grain (of wood stock). See Figure 9-2.
Figure 9-2
Figure 9-3
9.4 Resawing
Resawing is the process of slicing stock to reduce
its thickness, or to produce boards that are thinner
than the original workpiece. Figure 9-4
demonstrates resawing.
The ideal blade for resawing is the widest one the
machine can handle, as the wider the blade the
better it can hold a straight line.
When resawing thin stock, use a push block, push
stick, or similar device to keep your hands away
from the blade.
9.3 Crosscutting
Crosscutting is cutting across the grain of the
workpiece, while using the miter gauge to feed the
workpiece into the blade.
Slide the bar of the miter gauge into the end of the
slot on the table.
The right hand should hold the workpiece steady
against the miter gauge, while the left hand pushes
the miter gauge past the blade, as shown in Figure
9-3.
Do not use the fence in conjunction with the miter
gauge. The offcut of the workpiece must not be
constrained during or after the cutting process.
Using the fence in conjunction
with the miter gauge can cause binding and
possible damage to the blade.
Figure 9-4
9.5 Blade Lead
Blade lead, or drift, is when the blade begins to
wander off the cutting line even when the band saw
fence is being used. Figure 9-5 shows an example
of blade lead. It is more common with small, narrow
blades, and is almost always attributable to poor
blade quality, or lack of proper adjustments. Inspect
the band saw for the following:
• Fence not parallel to miter slot and blade.
• Blade not tensioned correctly.
• Blade is dull.
• Teeth have excessive “set” on one side of
blade.
•Workpiece being fed too quickly.
22
Figure 9-5
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 and
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 formation until cutting is at its most efficient
rate (refer to “Evaluating Cutting Efficiency”
below). Allow the saw to complete the cut.
6. The blade is now considered ready for use.
10.3 Evaluating cutting efficiency
10.0 Operation – Metal
Consult section 8.0 for identification of the controls.
Never operate band saw without blade and wheel
covers in place and secured.
The following section contains basic information and
is not intended to cover all possible applications or
techniques using the band saw. Consult published
sources of information, acquire formal training,
and/or talk to experienced band saw users to gain
proficiency and knowledge of band saw operations.
(The following figures may or may not show your
specific band saw, but procedures are the same.)
10.1 General Procedure
1. Setup the saw to match the specific material to
be cut. “Wood Mode” for wood or “Metal Mode”
for metal.
2. Install the proper blade for use with the material
to be cut.
3. Make sure the blade and upper and lower
bearings are properly adjusted for tension and
tracking.
4. Adjust blade guide assembly so that the guide
bearings are just above workpiece (about 3/16”)
allowing minimum exposure to blade. See
Figure 9-1.
The best way to determine whether a blade is
cutting efficiently is to observe the chips formed by
the cutting.
• If chip formation is powdery, then the feed rate
is too light, or blade is dull.
• If the chips formed are curled, but colored – blue
or straw colored from heat generated during the
cut – then feed rate is excessive.
• If chips are slightly curled and not colored by
heat, then the blade is sufficiently sharp and is
cutting at its most efficient rate.
11.0 Blade Selection Guide
Proper blade selection is just as important to band
saw operation as is blade speed and material feed.
Proper blade selection will impact blade life,
straightness of cut, cut finish, and efficiency of
operation. Excessive blade breakage, stripping of
teeth, and waviness of cut are some of the results of
improper blade selection.
Using the proper blade for the job will increase the
operating efficiency of your band saw, help reduce
necessary saw maintenance, and improve your
productivity. Thus, it is important to follow certain
guidelines when selecting a saw blade.
Here are factors to consider when selecting a blade:
•The type of material you will be cutting.
10.2 Blade break-in procedure
New blades are very sharp and therefore have 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
specific blades on specific 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 low speed. Start the cut with
a very light feed rate.
• The thickness of the workpiece or part.
• The features of the workpiece or part, such as
bends or curves with small radii.
These factors are important because they involve
basic concepts of saw blade design. There are five
(5) blade features that are normally changed to meet
certain kinds of sawing requirements.
They are:
• width
• pitch (number of teeth per inch)
• tooth form (or shape)
23
• the "set" of the teeth
• the blade material itself.
11.1 Width
Band saw blades come in different standard widths,
measured from the back of the blade to the tip of the
tooth. Generally, wider blades are used for ripping
or making straight cuts; narrower blades are often
used when the part being cut has curves with small
radii. When cutting straight lines with a narrow
blade, the blade may have a tendency to wander,
causing blade lead.
The thinner the blade, the tighter will be the
minimum radius of cut. Always use widest blade
possible for the job.
General rules for blade selection:
•Select coarser pitch blades for thicker or softer
material.
•Select finer pitch blades for thinner or harder
material.
• Use fine pitch blades to obtain a smooth finish.
• Use coarse pitch blades to obtain faster cutting
speeds (thick material).
Figure 11-1
11.3 Shape
Figure 11-2 shows common types of tooth shape.
Tooth shape has an effect on cutting rate, and with
few exceptions, the Skip and Hook types are used
to obtain higher feed rates when cutting thick
workpieces. Variable-tooth blades are also
available, which combine features of the other
styles.
•To prevent premature blade wear, use fastest
practical speed.
•Adjust feed rate to ensure continuous cutting
action.
•Run the bandsaw with blade centered in upper
and lower guides, and guide fingers adjusted as
close as possible without touching the blade or
weld joint. Never adjust guide fingers while
blade is running. Failure to comply may cause
serious injury.
11.2 Pitch
Pitch is measured in "teeth per inch" (TPI). Figure
11-1 shows blades with different pitches. A fine pitch
(more teeth per inch) will cut more slowly 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 the blade pitch. 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 good clean cuts.
General rule: Use a blade that will have no fewer
than 6 and no more than 12 teeth in the workpiece
at any given time.
Figure 11-2
Note: When cutting thin materials, the rule for blade
pitch is to have a minimum of two teeth engaging
the material being cut at all times.
Standard Tooth – generally used to cut ferrous
metals, hard bronze, hard brass, and thin metals.
Skip Tooth – have better chip clearance (larger
gullet) and are used on softer, non-ferrous materials
such as aluminum, copper, magnesium, and soft
brass.
Hook Tooth – provides a chip breaker and has less
tendency to gum up in softer materials. Used in the
same materials as skip tooth but can be fed faster
than standard or skip tooth blades.
11.4 Set
The term "set" refers to the way in which the saw
teeth are bent or positioned. Set patterns are usually
selected depending on the type of material that
needs to be cut. Three common set patterns are
shown in Figure 11-3.
Generally:
24
Straight Set – used for free cutting non-ferrous
materials; i.e., aluminum, magnesium, plastics, and
wood.
Wavy Set – used on materials of varying thickness
(pipe, tubing, and structural shapes).
Raker Set – used in large cuts on thick plate and bar
stock where finish of cut is not as important as
speed.
Figure 11-3
11.4.1 Kerf
Kerf is the width of a cut. Kerf will vary according to
the set of the blade teeth.
11.5 Material
Band saw blades can be made from different types
of materials. Some of the most common include
spring steel, carbon steel, carbon steel equipped
with a high speed or welded edge (bi-metal), or
carbide tips. A special type of saw blade is made
from "high speed steel"; these should not be used
on band saws with low rates of speed.
Carbon Steel – low cost, for use with non-ferrous
materials, wood, and plastics.
High Speed Steel – resists heat generated by dry
cutting. Used for ferrous metals.
Alloy Steel – tough and wear resistant, cuts faster
with longer blade life. Used on hard materials. More
expensive than carbon or high speed steel.
Carbide Tipped – for cutting unusual materials such
as uranium, titanium, or beryllium.
11.5.1 Gage
Gage is the thickness of material from which the
blade is produced. The thicker the material, the
stronger the blade.
11.6 Blade breakage
Band saw blades are subject to high stresses and
breakage may sometimes be unavoidable.
However, many factors can be controlled to help
prevent most blade breakage.
Here are some common causes for breakage:
1. Misalignment of blade guides.
2. Feeding work too fast.
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 workpiece.
7. Faulty weld on blade.
25
12.0 Non-Metal Blade Chart
Identify the material and thickness of your workpiece. Table 3 will show the recommended PITCH, blade TYPE,
and FEED RATE.
Key: H – Hook L – Low

Study the part drawing or prototype, or actually measure the smallest cutting radius required, and locate this
radius (in inches) on the chart at the right. Follow the curve to where the approximate blade width is specified. If
a radius falls between two of the curves, select the widest blade that will saw this radius.
This procedure should be used for making initial blade selections. These recommendations can, of course, be
adjusted to meet specific requirements of a cutting job. Compromises may be necessary if you cannot find all
needed specifications in a single blade.

15.0 User-maintenance
Before any intervention on the
machine, disconnect it from the electrical
supply by pulling out the plug. Failure to comply
may cause serious injury.
Clean band saw regularly to remove any resinous
deposits and sawdust.
Keep miter slot, and guide bearings, clean and free
of resin.
Keep blade clean and sharp. Check it periodically
for cracks or other signs of wear.
The drive belt should be checked periodically. If it
looks worn, frayed, glazed or otherwise damaged,
replace it.
Check that the cleaning brush over the band wheel
is working properly and remove any deposits from
the band wheels to avoid vibration and blade
breakage.
Do not let saw dust build up in the upper and lowerwheel housings. Vacuum or blow out dust from
inside cabinet. (Use proper dust mask equipment).
The table surface must be kept clean and free of rust
for best results. If rust appears, it can often be
removed with a mixture of household ammonia,
good commercial detergent and #000 steel wool.
Alternatively, commercial rust removers can be
found at many hardware stores.
Apply a light coat of paste wax to the table surface.
Aerosol protectants are also available in major
hardware stores and supply catalogs. Whatever
method is chosen, the coating should protect the
metal and provide a smooth surface, without
staining workpieces.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
Connect the band saw to a JET dust collection
system of appropriate capacity.
Vacuum out the motor fan cover.
15.1 Lubrication points
1. Periodically apply a light, non-hardening grease
to rack and pinion system of guidepost.
2. Grease sliding surfaces of the table trunnions.
3. Oil any pins, shafts, and joints. (Do not get oil
on pulleys or belts.)
4. Clean and oil the tensioning mechanism if it
becomes difficult to adjust.
Note: Bearings on the band saw are pre-lubricated
and sealed, and do not require attention.
15.2 Additional servicing
Any other servicing should be performed by an
authorized service representative.
