Setting Blade Speed
Introduction
This manual includes the operating and maintenance
instructions for the JET 10-inch by 16-inch Cut Off Band
Saw, Models J-7020/J-7040. This manual also includes
parts listings and illustrations of replaceable parts.
1. The blade speed is controlled by an adjustment
mechanism on the right end of the saw. Speed
increases when the adjustment knob is turned
counterclockwise. Speed decreases when the
knob is turned clockwise.
2. A placard on the drive belt guard provides recom
mended speeds for various materials.
Operating Instructions
3. A speed indicator is provided on the barrel of the
adjustment mechanism. The indicator provides
speed indications in feet per minute and meters
per minute. (The meters per minute values are
shown in parenthesis on the indicator.)
4. The feed rates on the placard are expressed in
meters per minute. The feed rate graduations
available on the indicator may not match the
recommended feed rate. An approximate speed
may therefore be required. For example, to set a
speed rate of 25 meters per minute, the indicator
would be set about midway between 21 meters-
per-minute and the 30 meters-per-minute gradu-
ations.
Controls
The operating controls for the saw are provided in a
control panel on the left side of the machine. The con-
trol panel is mounted on a pivoting tube. The pivoting
tube allows the operator to position the control panel in
a convenient location.

1. A power-on light is provided on the left side of the
control panel. The power-on light indicates when
power is connected to the machine.
2. A n emergency stop button is provided on the
control panel. The emergency stop button pro-
vides a means to rapidly cut off electrical
power.
3. The saw motor pushbutton switch starts the saw
motor and the E-stop button stops the saw motor.
4. A green pushbutton switch is provided to the right
of the emergency stop pushbutton. The pushbutton
opens an electro-magnetic valve in the hydraulic
cylinder circuit. Opening the valves allows the saw
head to move downward and put the saw blade in
contact with the workpiece.
5. A red release button on the electro-magnetic
valve provides a means to lower the saw head
when power to the machine has been discon-
nected (see figure 4).

Controlling the Cut:
Hydraulic Feed Control
Figure 4: Lowering head with power off
The weight of the saw arm provides all the force
needed to move the saw blade through the workpiece.
In fact, if the full weight of the arm is allowed to make
the cut, rapid blade wear and poor cutting accuracy
will result. A hydraulic feed control is provided that
gives the operator a means to control the speed and
efficiency of cutting.
The hydraulic cylinder is attached between the saw
base and the saw head. The hydraulic cylinder resists
movement of the saw head in the downward direction.
However, the hydraulic cylinder offers no resistance
when the saw head is raised upward.
The amount of downward force can be controlled by
using the feed rate control valve. When the valve is
opened slightly, the saw head will move downward. The
further the valve is opened, the faster the saw head will
move downward.
The feed control is adjusted by the operator until the
saw is operating efficiently. This is usually determined
by observing the chip formation. (See Evaluating Blade
Efficiency for more information on cutting efficiency.)
Evaluating Cutting Efficiency
Is the blade cutting efficiently? The best way to de-
termine this is to observe the chips formed by the cut-
ting blade.
If the chip formation is powdery, then the feed rate
is much too light, or the blade is dull.
If the chips formed are curled, but colored — that
is, either 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.
Blade Selection
The cut-off saw is provided with a saw blade that is
adequate for a variety of cut-off jobs on a variety of
common materials. A 4/6 vari tooth bi-metal blade
(5674011) and a 6/10 vari tooth bi-metal blade
(5674021) are available from JET .

Saw
Head
A coarse blade could be used for a solid steel bar
but a finer tooth blade would be used on a thin-wall
tube. In general, the blade choice is determined by
the thickness of the material; the thinner the material,
the finer the tooth pitch.

Work Setup
A minimum of three teeth should be on the work
piece at all times for proper cutting. The blade and
workpiece can be damaged if the teeth are so far apart
that they straddle the workpiece.
For very high production on cutting of special mate-
rials, or to cut hard-to-cut materials such as stainless
steel, tool steel, or titanium, you can ask your industrial
distributor for more specific blade recommendations.
Also, the supplier who provides the workpiece material
should be prepared to provide you with very specific
instructions regarding the best blade (and coolant or
cutting fluid, if needed) for the material and shape sup-
plied.
Securing the Workpiece for
Square Cuts
1. Raise the saw head (refer to Figure 5).
2. Slide the left vise jaw far enough to the left to allow
the workpiece to be placed in the vise.
3. Place the workpiece on the work table. If the
workpiece is long, provide support at the other end.
It may also be necessary to provide additional down-
ward clamping to hold the workpiece securely on
the work table.
4. Turn clamping hand wheel clockwise to clamp the
workpiece in position against the fixed (right) vise
jaw.
Blade Break-in Procedures
New blades are very sharp and, therefore, have a
tooth geometry which 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. However, the following proce-
dure will be adequate for break-in of JET -supplied blades
on lower alloy ferrous materials.
5. After completing the cut, turn the clamping hand
wheel counterclockwise and slide the left jaw away
from the workpiece.

1. Clamp a round section workpiece in the vise. The
workpiece should be 2 inches or larger in diameter.
Work Table
2. Set the saw on low speed. Start the cut with a very
light feed rate.
3. When the saw has completed 1/3 of the cut, in-
crease the feed rate slightly and allow the saw to
complete the cut.
4. Keep the same hydraulic cylinder setting and begin
a second cut on the same or similar workpiece.
Figure 5: Securing workpiece
5. When the blade has completed about 1/3 of the cut,
increase the feed rate. Watch the chip formation
until cutting is at its most efficient rate and allow the
saw to complete the cut (see Evaluating Blade Effi-
ciency). The blade is now considered ready for
regular service.
Adjusting the Vise for Angle
Cuts
1. Referring to Figure 6, loosen the angle locking screw
and the pivot screw on the left vise jaw.

2. Turn the locking handle on the round, angle-setting
block counterclockwise to unlock the block. Slide
the block until the pointer on the block is aligned
with desired angle (see figure 7). Tighten the lock-
ing handle to set the angle.
3. Set the workpiece in the vise. Put the front end of
the workpiece against the corner of the right vise
jaw. Put the rear end of the workpiece against the
angle-setting block.
4. Turn clamping hand wheel clockwise until the left
vise jaw is parallel with the workpiece. Tighten the
pivot screw and angle locking screw on the left vise
jaw. Clamp the workpiece in position.
5. After completing the cut, turn the clamping hand
wheel counterclockwise and slide the left jaw away
from the workpiece.

Factory or Field Procedure
1. Raise the saw head enough to allow the saw motor
to operate.
3. The coolant flow can be stopped in two ways:
1) By using the coolant pump switch on the
electrical equipment box, or
2) By closing the coolant flow valves on the top,
rear of the saw head.
2. Loosen four knobs securing the blade cover. Lift
the cover and swing it backward.
3. Remove the blade guard mounted on the left blade
guide support.
Coolant Mixture and Quantity
4. Remove both blade guide bearing brackets.
The general purpose coolant is a mixture of water
soluble oil and water. Mix one part of soluble oil (TRIM
SOL) to ten parts of water (one quart oil, ten quarts of
water). Eleven quarts of coolant are required for the
coolant pump to operate properly.
There are numerous coolants on the market that are
formulated for special applications. Consult your local
distributor for details in the event you have a long range
production task, or are required to cut some of the
more exotic materials.
NOTE: Maintain proper tension at all times using the
blade tensioning mechanism.
5. Loosen the center locking screws in all three hex
adjustment screws on the blade tensioning mecha-
nism (see figure 10).
CAUTION: WHILE PERFORMING THE FOLLOWING,
KEEP THE BLADE FROM RUBBING EXCESSIVELY
ON THE SHOULDER OF THE WHEEL. EXCESSIVE
RUBBING WILL DAMAGE THE WHEELAND/OR THE
BLADE.
Adjustments
6. Start the saw. Slowly turn the single hex adjustment
screw at the rear of the tracking mechanism to tilt
the idler wheel. Do not turn either of the other two
adjustment screws. Turn the adjustment screw until
the blade is touching the shoulder of the idler wheel.
The efficient operation of the cut-off saw is depen-
dent upon the condition of the saw blade. If the perfor-
mance of the saw begins to deteriorate, the first item
that you should check is the blade.
11
If a new blade does not restore the machine’s cut-
ting accuracy and quality, refer to the Troubleshooting
section (or the blade manufacturer’s guide) for condi-
tions to consider and adjustments that can be made to
increase the life of the blade.
NOTE: Turning the screw inward causes the blade to
move toward the shoulder of the wheel. Turning the
screw outward causes the blade to move away from
the shoulder.
To change the blade, refer to Changing Blades in
the Maintenance section. To adjust the blade tracking,
refer to the following procedures.
7. Turn the single hex adjustment screw so the blade
starts to move away from the shoulder of the wheel
— then turn the single hex adjustment screw in the
other direction so the blade stops, then moves slowly
toward the shoulder.
Blade Tracking Adjustment
Blade tracking has been tested at the factory. Ad-
justment is rarely required when the blade is used prop-
erly or if the blade is correctly welded. (See figure 10
for location of blade tracking adjustment screws.)
WARNING: KEEP FINGERS CLEAR OF THE BLADE
AND WHEEL TO AVOID INJURY.
8. Turn the single hex adjustment screw to stop the
motion of the blade on the wheel as it gets closer to

the wheel shoulder. Put a 6-inch length of paper
between the blade and the wheel as shown in figure
11. The paper should not be cut as it passes be-
tween the wheel shoulder and the blade.
should rarely require adjustment. When adjustment is
required, adjust immediately. Failure to maintain proper
blade adjustment may cause serious blade damage or
inaccurate cuts.
It is always better to try a new blade when cutting
performance is poor. If performance remains poor af-
ter changing the blade, make the necessary adjust-
ments.
9. Turn the single hex adjustment screw a small amount.
Repeat the insertion of the paper between the wheel
shoulder and the blade until the paper is cut in two
pieces.
If a new blade does not correct the problem, check
the blade guides for proper spacing. For most effi-
cient operation and maximum accuracy, provide 0.001
inch clearance between the blade and the guide bear-
ings. The bearings will still turn freely with this clear-
ance. If the clearance is incorrect, the blade may track
off the drive wheel.
NOTE: You may have to repeat the check with the
paper several times before the blade and the shoulder
cuts the paper into two pieces. Do not hurry the ad-
justment. Patience and accuracy here will pay off with
better, more accurate, quieter cutting and much longer
machine and blade life.
10. When the paper is cut, turn the hex adjustment
screw slightly in the counterclockwise direction. This
assures that the blade is not touching the shoulder
of the wheel.
CAUTION: CHECK THE BLADE TO MAKE SURE THE
WELDED SECTION IS THE SAME THICKNESS AS
THE REST OF THE BLADE. IF THE BLADE IS
THICKERATTHE WELD, THE GUIDE BEARINGS MAY
BE DAMAGED.
11. Shut off the saw.
12. Hold the hex adjustment screws with a wrench and
tighten the center locking screws. Make sure the
hex adjustment screws do not move while tightening
the center screws.

tion of the disk you have cut from the bar stock. Mea-
sure at the top and bottom of the disk.
The saw blade can be considered correctly adjusted
when the variation measure is no more than 0.012 inch
across the face of the disk.
If you do not have a piece of 2-inch bar stock avail-
able for a test cut, use a larger diameter test piece
rather than a smaller one. The maximum thickness
variation on any test piece should be no more than
0.003 inch, per side, per inch of stock diameter.
4. Position the bearing by turning the bushing. Set
the clearance at approximately 0.001 inch. (The
blade should be in a vertical position between the
bearings. (See figure 13.)
5. Tighten the center locking screw with anAllen wrench
while holding the eccentric bushing in position with
the 3/4-inch wrench.
6. Use the same procedure to adjust the other guide
bearing.
Adjustment of the Limit
Switch
1. The limit switch is provided to shut off the saw motor
when the workpiece is cut through.
7. When the adjustment is correct, the guide bear-
ings should rotate freely with slight pressure of the
finger (with the blade stopped).
8.Adjust blade-edge bearings so they just touch
the back edge of the blade (see figure 19).
2. To set the limit switch, loosen the jam nut on the limit
switch stop (figure15).
Test Cutting to Verify
AdjustmentAccuracy
3. Adjust the stop as required and retighten jam nut.
Test cuts can be used to determine whether or not
you have adjusted the blade accurately. Use 2-inch
round bar stock to perform these test cuts, as follows:
1. With the bar stock securely clamped in the vise,
make a cut through the bar stock. (See figure 14.)
Jam Nut
2. Mark the top of the bar stock.

3. Move the bar stock about 1/4-inch past the blade so
you can begin a second cut.
4. Rotate the bar stock 180 degrees so the mark you
made is now at the bottom of the cut.
