Remove any plastic or holding straps from
around the band saw. Areas of the machine
have been given a protective coating at the
factory. This should be removed using a soft
cloth moistened with kerosene or a cleanerdegreaser. Do not use gasoline, paint thinner, or
lacquer thinner as these will damage painted
surfaces. Do not use an abrasive pad.
Determine the final location for the saw and
allow for a sufficient work space around it.
The saw is extremely heavy.
Use a hoist to lift.
When moving the saw/stand
top assembly the cutting head, or “bow”,
should be in the down position.

Electrical Connection
All electrical connections
must be done by a qualified
electrician. All adjustments or repairs must
be done with the machine disconnected from
the power source, unplugged. Failure to
comply may result in serious injury!
The Model J-9180 bandsaw is rated at 230V.
This machine is not supplied with a plug. Use a
plug and outlet rated at least 20amps. The
circuit for the machine should also be protected
by at least a 20 amp circuit breaker or fuse.
Make sure that the blade moves in the
correct direction. If it does not, simply reverse
two of the phase wires on the supply input.
The sawing machine is now ready for use.

Controls and Indicators
Control Panel
The operating controls for the bandsaw are
located on the control panel (Figure 4) and
consist of the following controls and indicators:
Emergency Stop Switch – by depressing this
switch the user can quickly stop the machine
when it is in operation; to restart, turn clockwise
slightly to release then press Start switch
Feed Rate Control – used in conjunction with the
Feed Rate Start/Stop Control (see below); this
knob is used to set the downward head speed
that is applied to the saw blade. The feed rate is
proportional to the opening of the valve. When
set to zero, the saw head is locked in position.
Increasing the valve opening (counter-clockwise
adjustment) increases the feed rate; decreasing
the valve opening (clockwise adjustment)
reduces the feed rate.
Motor Speed Selector – select Low for 137
SFPM, High for 275 SFPM; machine will not
operate when Off is selected.
On/Off Switch – main power switch
Standby Lamp Indicator – indicates that power is
present, i.e., machine is plugged in and On/Off
Switch in set to ON.
Start Switch – press to start machine, also: set
On/Off Switch to ON, select Motor Speed
Selector to Low or High, Emergency Stop must
be released.
Feed Rate Control
The Feed Rate Controls (Figure 5) are mounted
on the hydraulic cylinder located below the
control panel.
With the Feed Rate Start/Stop (F) lever in the
locked position the saw head is prevented from
descending; in the unlocked position the saw
head will descend at the rate determined by the
Feed Rate Control (G) setting.
Blade Tension Indicator

Blade Selection
The cut-off saw is delivered with a saw blade
that is adequate for a variety of cut-off jobs on a
variety of common materials. A general-purpose
blade is provided as standard equipment with
the machine.
Optional blades for specific applications are
available from JET. (Refer to the Parts section
for saw blade part numbers.)
A coarse blade could be used for a solid steel
bar, but a finer tooth blade would be used on a
thin-wall steel tube. In general, the blade choice
is determined by the thickness of the material;
the thinner the materials; the finer the tooth
pitch.
A minimum of three teeth should be on the
workpiece 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
materials, or to cut hard-to-cut materials such as
stainless steel, tool steel, or titanium, call JET
for more specific blade recommendations. JET
can provide you with very specific instructions
regarding the best blade (and coolant or cutting
fluid, if needed) for the material or shape
supplied.
Blade Break-in Procedures
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.
However, the following procedure will be
adequate for break-in of JET-supplied blades on
lower alloy ferrous materials.
1. Clamp a section of round stock in the vise.
The stock should be 2 inches or larger in
diameter.
2. Operate the saw at low speed. Start the cut
with a very light feed rate.
3. When the saw has completed 1/3 of the cut,
increase the feed rate slightly and allow the
saw to complete the cut.
4. Keep the hydraulic cylinder needle valve in
the same position and begin a second cut
on the same or similar 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 (refer to Evaluating Blade
Efficiency below). The blade is now consid-
ered ready for use.
Operations
Hydraulic Feed Control
The weight of the saw head provides the force
needed to cut through the workpiece. The cut-off
saw has a hydraulic cylinder that controls the
feed rate of the saw.
The hydraulic feed control circuit consists of a
single acting hydraulic cylinder and a feed rate control. The feed control cylinder resists motion
in the downward direction to control the feed
rate. The control cylinder offers no resistance
when raised upward.
The feed rate adjustment (G, Fig. 4) controls the
rate at which the saw head is lowered. The
control knob (needle valve) controls the rate at
which the hydraulic fluid is released from the
hydraulic cylinder. When the needle valve is
closed, the cylinder is locked. With the needle
valve slightly open, the cylinder permits slow, or
light, downward force. Opening the needle valve
further increases the feed rate.
The needle valve is adjusted until the saw is
operating efficiently. The efficiency of operation
is usually evaluated by observing chip formation.
Blade efficiency is further described below.
A lever (F, Fig. 5) is used to permit or stop the
saw head from descending regardless of the
feed rate adjustment (G, Fig. 5) setting.
Evaluating Cutting Efficiency
Is the blade cutting efficiently? The best way to
determine this is to observe the chips formed by
the cutting blade.
If the chip formation is powdery, then the feed is
much too light or the blade is dull.
If the chips formed are curled, but colored – 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.
10
Setting the Work Stop
Referring to Figure 7:
The work stop is an accessory that is included
with the JET J-9180 Bandsaw. It is used to set
up the saw for making multiple cuts of the same
length.
Do not allow the blade to rest
on the workpiece when the saw is not
cutting.
Installation
1. Screw the threaded end of the distance set
rod (A) into the hole at the front of the base
(B) as shown.
2. Secure by tightening the lock nut (C) with a
22mm hex wrench.
Adjustment
3. The distance set bracket (D) is moved along
the distance setrod (A) by loosening the
lock handle (H). The stop rod (F) can be
repositioned (G) by loosening lock handle
(E) – also by loosening the lock nut (C) and
rotating the set rod (A) to reposition the
angle of the bracket (D).
Quick Release Vise Operation
Referring to Figure 8:
The vise on the J-9180 bandsaw comes
equipped with a quick-release handle that
permits the workpiece to be rapidly repositioned
or changed for a repeated cutting operation
while requiring only one initial adjustment of the
vise handwheel. This is done as follows:
1. Place the quick-release handle (A) in the up
position as shown.
2. Turn the handwheel (B) counterclockwise
until the workpiece can be placed in
position.
Figure 7
3. Place the workpiece (C) in the vise (D) and
against the work stop (E); turn the hand-wheel (B) until the vise begins to clamp onto
the workpiece. Then back the handwheel off
just enough to permit the workpiece to slide
in and out of the vise.
4. Place the quick-release handle (A) in the
down position. The workpiece is secure and
ready for cutting.
The vise is now set up for a repeated cutting
operation. Simply raise the quick-release
handle, reposition or replace the workpiece and
reset the handle down again.
11
Figure 8
Miter Cuts
Referring to Figure 9, the J-9180 bandsaw is capable
of making angle cuts from 0–60º. The vise remains
stationary while the saw head is adjusted as follows:
1. Place the saw head (F) in the raised position so
the blade doesn't catch in the table slots.
2. Set the lock handle (A) to the unlock position as
indicated by the arrows.
3. Using handles (B and C), rotate the saw head (F)
to any desired angle within a range of 0º (square
cut) to 60º, setting it to the scale (D) on the base.
4. Set the lock handle (A) to the lock position.
Note: Two miter stops (E) on either side of the saw
base set the miter range of 0–60º. Adjust only if
necessary so the saw travel stops at 0º and 60º.
Coolant Flow Control
The coolant pump must be
submerged before operating to prevent damage
to the pump.
A coolant pump, which provides coolant to the
workpiece, runs at all times when the machine is
turned on.
Two coolant flow control valves (A, Fig. 10), located
on the top of the bearing blocks, control the amount
of flow from the nozzles. Coolant flow should be
adjusted to be no more than the saw blade can draw
into the workpiece by the movement of the blade. To
stop coolant flow, turn the control valves fully
counterclockwise.
Adjustments
Blade Guide Adjustment
Refer to Figure 11. The J-9180 Bandsaw has two
blade guide assemblies; one is stationary (A) and
mounted to the body of the saw head. The other,
consisting of a blade guide support or bracket (B) and
blade guide (C), is adjustable.
Figure 9
Figure 10
The position of the blade guides is important in order
to make accurate cuts and prolong blade life and is
determined by the size of the workpiece. Adjustment
is made as follows:
1. Place the workpiece (D) in the vise (E) and clamp
tightly.
2. Loosen the lock handle (F).
3. Slide the guide support (B) left or right so that it
just clears the piece to be cut (D).
4. Tighten the lock handle (F).
12
Figure 11
Guide Bearing Adjustment
r
Referring to Figure 12:
Guide bearings are located on either side of the saw
blade and provide stability for the blade when the
saw is in operation. These bearings rotate on an
eccentric shaft so the distance from the blade can be
adjusted for optimal performance.
Guide bearings are initially adjusted at the factory
and should rarely require adjustment.
It is always better to try a new blade when cutting
performance is poor. If performance remains poor
after changing the blade, check the blade guides for
proper guide bearing spacing. For most efficient
operation and maximum accuracy, clearance
between the blade and the guide bearings should be
0.001-inch. The bearings will still turn freely with this
clearance. If the clearance is incorrect, the blade may
track off the drive wheel.
Disconnect the bandsaw saw
from its electrical power source.
If required, adjust guidebearings on one assembly
then the other as follows:
1. Using a 14mm wrench loosen two lock nuts (A)
that secure the eccentric bushings (B) while
maintaining the positions of the eccentric
bushings with a 6mm wrench.
2. Position the bearings (B) by adjusting the
bushings (C) with the 6mm wrench. Set the
clearance between the bearings (B) and blade
(D) at approximately 0.001 inch.
Note: Only the bearing towards the front is
mounted on an eccentric bushing. Make adjustments on this bearing.
When properly adjusted, the blade should be in a
vertical position between the bearings as shown
in Figure 13.
3. While maintaining the new position of the
bushings with the 6mm wrench, secure the
settings by tightening the lock nuts (A).

Limit Switch Adjustment
Refer to Figure 14.
The J-9180 bandsaw should shut off automatically
when a cut is completed. If not, the limit switch (A)
located below the control panel (Figure 1) probably
needs to be adjusted as follows:
Disconnect the cut-off saw from
its electrical power source.
1. Place the saw in the lowered position to repres-
ent the completion of a cutting operation.
The microswitch wheel (E) should be pressed
against the plate (F) which is attached to the
hydraulic cylinder bracket (G). If this is not the
case, make a note of how much the switch assembly (A) should be repositioned upwards.
2. Using a crosspoint screwdriver, remove two
screws (C) and the switch (A) from its mounting
plate (B).
3. With a 3mm hex wrench, loosen two screws (D)
and reposition the mounting plate (B) as
determined in step 1.
4. Tighten the mounting plate screws (D) and
reinstall the switch assembly (A).
5. Test to verify that the bandsaw shuts off when a
cut is completed. If it does not, repeat above
steps.

months.
2. Clean up accumulated saw cuttings after
use. Make sure the lead screw and rapid nut
are kept free from saw cuttings and other
material that would cause damage.
3. Clean the chip sludge from the coolant tank.
The frequency should be determined by how
often the saw is used.
Lubrication
Lubricate the following components at the
specified frequencies and using the lubricants
defined as follows:
Ball Bearings – the bearings are lubricated and
sealed – periodic lubrication is not required.
Blade Guide Bearing – the bearings are lubricated and sealed – periodic lubrication is not
required.
Change coolant on a frequency appropriate to
the type of coolant being used. Oil based
coolants can sour. Refer to the coolant
supplier’s instructions for change frequency.
The general-purpose coolant is a mixture of
water-soluble oil or synthetic based coolant and
water. Mix one part of coolant to ten parts of
water (one quart of oil to ten quarts water). Ten
quarts of coolant is the amount 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.
Wheel Bushings – six to eight drops of oil each
week.
Pivot Points, Shafts, and Bearingareas – six
to eight drops of oil each week.

Excessive blade
breakage
Premature blade
dulling
1. Material loose in vise.
2. Incorrect speed or feed.
3. Teeth too coarse for material.
4. Incorrect blade tension.
5. Saw blade is in contact with workpiece before the saw is started.
6. Misaligned guides.
7. Cracking at weld.
1. Blade teeth too coarse.
2. Blade speed too high.
3. Inadequate feed pressure.
4. Hard spots in workpiece or scale
on/in workpiece.
5. Work hardening of material
(especially stainless steel).
6. Insufficient blade tension.
7. Operating saw without pressure on
workpiece.
1. Clamp work securely.
2. Check Machinist’s Handbook for
speed/feed appropriate for the
material being cut.
3. Check Machinist’s Handbook for
recommended blade type.
4. Adjust blade tension to the point
where the blade just does not slip on
the wheel.
5. Start the motor before placing the
saw on the workpiece.
5. Increase feed pressure by reducing
spring tension.
6. Increase tension to proper level.
7. Do not run blade at idle in/on
material.
Bad cuts (crooked)
1. Workpiece not square with blade.
2. Feed pressure too fast.
3. Guide bearings not adjusted
properly.
4. Inadequate blade tension.
5. Span between the two blade guides
too wide.
6. Dull blade.
7. Incorrect blade speed.
8. Blade guide assembly is loose.
9. Blade guide bearing assembly loose.
10. Blade track too far away from wheel
flanges.
11. Guide bearing worn.
1. Adjust vise so it is square with the
blade. (Always clamp the workpiece
tightly in the vise.)
2. Decrease pressure.
3. Adjust guide bearing clearance to
0.001 inch (0.002 inch maximum).
4. Gradually increase blade tension.
5. Move blade guide bracket closer to
work.
6. Replace blade.
7. Check blade speed.
8. Tighten blade guide assembly.
