Grounding Instructions
1.75 HP Single Phase Motor
This machine must be
grounded while in use to protect the operator
from electric shock.
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric
shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a
matching outlet that is properly installed 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 installed by a
qualified electrician.
Improper connection of the equipment-
grounding 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 equipment-
grounding conductor. If repair or replacement 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. Use only
three wire extension cords that have three-prong
grounding plugs and three-pole receptacles that
accept the tool’s plug.
Repair or replace a damaged or worn cord
immediately.
115 Volt Operation
If your band saw's Stock No. is 710750, it is
wired from the factory for 115 volt operation. The
power cord has a plug that looks like A, Fig. 1.
and is used in an outlet that looks like B, Fig. 1.
A temporary adapter with a grounding ear
secured with a screw (C, Fig. 1) may be used to
connect this plug to a two-pole receptacle if a
properly grounded outlet is not available. The
temporary adapter should only be used until a
properly grounded outlet can be installed by a
qualified electrician. This adapter is not
applicable in Canada. The green colored
grounding ear, lug, or tab, extending from the
adapter, must be connected to a permanent
ground such as a properly grounded outlet box,
as shown in C, Fig. 1.
Figure 1
230 Volt Operation
If 230V, single phase operation is desired, the
following instructions must be followed:
1. Disconnect the machine from the power
source.
2. This band saw is supplied with four motor
leads that are connected for 115V operation
as shown in A, Fig. 2. For 230V operation
reconnect the leads as shown in B, Fig. 2.
3. The 115V attachment plug supplied with the
band saw (C, Fig. 2) must be replaced with
a UL/CSA listed plug suitable for 230V
operation (D, Fig. 2). Contact your local
Authorized JET Service Center or qualified
electrician for proper procedures to install
the plug. The band saw must comply with all
local and national codes after the 230V plug
is installed.
4. The band saw with a 230V plug should only
be connected to an outlet having the same
configuration (D, Fig. 2). No adapter is
available or should be used with the 230V
plug.
Important: In all cases (115 or 230 volts), make
certain the receptacle in question is properly
grounded. If you are not sure, have a registered
electrician check the receptacle.

Grounding Instructions
3 HP Single Phase Motor
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 event of
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
Improper connection of the equipment-
grounding 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 equipment-
grounding conductor. If repair or replacement 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 specifications on the motor plate of
the band saw. The machine should be
connected to a dedicated circuit.
230 Volt Operation
If your band saw's Stock No. is 710751, it is
wired from the factory for 230 volt operation You
may either install a plug or “hard-wire” the band
saw directly to a control panel.
If connecting a plug, use a proper UL/CSA listed
2-pole, 3-wire grounding plug suitable for 230V
operation.
If the band saw is to be hard-wired to a panel,
make sure a disconnect is available for the
operator. During hard-wiring of the band saw,
make sure the fuses have been removed or the
breakers have been tripped in the circuit to
which the band saw will be connected. Place a
warning placard on the fuse holder or circuit
breaker to prevent it being turned on while the
machine is being wired.
Extension cords
The use of an extension cord is not
recommended for this band saw. But if one is
necessary, make sure the cord rating is suitable
for the amperage listed on the machine’s motor
plate. An undersize cord will cause a drop in line
voltage resulting in loss of power and
overheating.
Use the chart in Table 1 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.

tighten the screws.
Note: This alignment will again be checked
once the guide rail has been tightened.
8. Move the fence assembly to the other side of
the blade as shown in Figure 10 so that the
pointer (B, Fig. 10) on the fence body points to
zero on the scale. Lock the fence by pushing
the handle (A, Fig. 10) down.
9. Move the guide rail (D, Fig. 10) with the locked
fence until the fence is flush against the blade
(C, Fig. 10). Do not unlock the fence to perform
this. Move the fence and guide rail together
when establishing the zero point.
Important: Do not force the fence into the
blade so that the blade bends.
10. With a 10mm wrench, tighten the five hex cap
screws located on the bottom of the front rail
that hold the guide rail to the front rail.
Note: After tightening the guide rail, double
check that the fence is still parallel to the miter
slot. Make additional adjustments if needed.

13
Adjusting Clearance between Fence and Table
Referring to Figures 11 and 12:
Check the clearance between the table and the
fence. The fence should not rub against the table
surface but be slightly above it. This gap should be
the same at the front of the table as it is at the rear.
If the gap between fence and table is not
consistent, loosen either of the hex nuts on the
hook (Figure 12) and rotate the sliding pad until the
fence/table gap is consistent across the full length
of the table. When this is achieved, tighten both
hex nuts.
Check the adjustment of the hook at the rear of the
fence. The hook should be positioned so that it
overlaps the rear rail by approximately 1/8”
(Fig. 12). To adjust the hook, loosen the upper hex
nut and slide the hook in or out as needed. Re-
tighten upper hex nut.
Resaw Guide
For resawing attach the post (A, Fig. 13) to the
fence with the lock knob (B, Fig. 13). There is a
slotted hole in the fence that will accommodate the
resaw kit. Position the post so that it is centered
with the front edge of the blade. The resaw guide
will give you a taller, single point contact surface
during resawing.
Miter Gauge
1. Place the miter gauge in the table slot.
2. With a square verify the miter gauge face is
square to the blade.
3. If the miter gauge is not square to the blade
loosen the lock knob (C, Fig. 13) and adjust to
the proper setting. Tighten the lock knob.
4. If the pointer is not at 90 degrees, loosen the
screw (D, Fig. 13) holding the pointer and move
the pointer to 90 degrees.
5. Re-tighten the screw.

Installing/Changing Blades
Disconnect machine from
power source. Blade teeth are sharp, use care
when handling the blade. Failure to comply may
cause serious injury.
1. Disconnect machine from power source.
2. Decrease blade tension by rotating the blade
tension handwheel (A, Fig. 17) according to the
arrow direction in until the handwheel stops.
3. Remove the table insert (B, Fig. 17).
4. Remove the tapered pin (C, Fig. 17) by using
the wrench attached with the pin together.
5. Lower the upper blade guide assembly
(H, fig. 18) by loosening the knob (F, Fig. 18)
and rotating the handwheel (G, Fig. 18).
6. Open upper and lower front doors (D, Fig. 17).
7. Carefully remove the blade from between
upper and lower blade guides; then remove the
blade from the upper and lower wheels.
8. Guide new blade through table slot (E, Fig. 17).
Place blade in upper and lower blade guides.
Note: Make sure blade teeth point down
toward table (see inset, Fig. 17), and toward
the front of the saw.
Hint: If the teeth cannot be made to point
down, try turning the blade inside out first, then
reattempt.
9. Position blade on the middle of the upper and
lower wheels.
10. Replace the table insert (B, Fig. 17) and
tapered pin (C, Fig. 17).
Before operating the band saw, the new blade must
be adjusted and blade guides re-adjusted. The
required adjustments are contained in the sections
listed below and which follow immediately:

Blade Tension
Blade tension is set with the blade tension
handwheel (A, Fig. 19) and is performed following
blade replacement and periodically as the blade
stretches from use.
Disconnect machine from
power source before making any adjustments.
Referring to Figure 19:
1. Set the blade tension by rotating the
handwheel according to the arrow directions in
Figure 19.
2. The gauge (B) indicates the approximate
tension according to the width of the blade in
inches. Initially, set the blade tension to
correspond to the width of your blade.
The JWBS-18X and JWBS-18X-3 come with a
3/4" blade so the tension should be set at 3/4"
when using this blade.
Note: The tension gauge can also be seen
from the front of the saw through the wheel
when the upper door is open.
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, slightly
release the tension on the blade – this will prolong
the blade’s life. Make a note of the specific tension
setting for that particular blade, as shown on the
gauge (B). The tension can then be re-set quickly
when band saw operations are resumed.
Blade Tracking
Tracking refers to the position of the saw blade on
the wheels while the machine is in operation.
Tracking has been factory-adjusted. However, it
should be checked occasionally, including after
every blade change.
Disconnect machine from
power source before making any adjustments.
Important: The blade must be properly tensioned
before adjusting blade tracking (see previous
section). Make sure the blade guides and other
parts of the machine will not interfere with the
movement of the blade.
To inspect and adjust tracking, proceed as follows:
1. Open upper front door to expose the wheel.
Rotate the wheel clockwise by hand and
observe the position of the blade on the wheel
Figure 19
through the window (E, Fig. 19). The blade
should ride upon the center of the wheel
(Figure 20).
2. If the blade tends to move toward the edge of
the wheel, loosen the wing nut (D, Fig. 19) and
slightly rotate the knob (C, Fig. 19). Rotating
the knob clockwise will cause the blade to
move toward the rear edge of the wheel.
Rotating the knob counterclockwise will cause
the blade to move toward the front edge of the
wheel.
Note: This adjustment is sensitive; perform it in
small increments and give the blade time to
react to the changes as you continue to rotate
the wheel.
3. When the blade is tracking properly in the
center of the wheel, re-tighten the wing nut
(D, Fig. 19).
4. Close the upper front door.

Overview – Bearing Adjustments
Thrust (back support) bearing are located behind
the saw blade and provide support to the back of
the blade when the saw is in operation.
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.
Upper Bearing Adjustments
Unplug the machine from power
source before making any adjustments! Blade
teeth are sharp - use care when working near
the saw blade. Failure to comply may cause
serious injury.
Note: Blade tension must be properly adjusted
prior to bearing guide setup. Refer to the Adjusting
Blade Tension section.
To adjust the thrust bearing (while referring also to
Figure 21):
1. Loosen the thumb screw (E) and slide the
bearing and bearing post until the space
between the thrust bearing (H) and the back
edge of the blade (G) is approximately 1/64”.
A convenient way to achieve this spacing is by
placing a dollar bill folded twice (four
thicknesses) between the blade and support
bearing – four thicknesses of a dollar bill is
approximately 1/64”.
To adjust the guide bearings (refer to Figure 22):
2. Loosen the locking handle (L) and slide the
assembly until the front of the guide bearings
rest just behind the gullet of the blade teeth
(see inset).
3. Loosen two wing nuts (J1, J2). Rotate the
adjustment handles (M) until the guide bearings
(K) rest lightly against the blade (N). Do not
force the guide bearings against the side of the
blade.
4. Tighten wing nuts (J1, J2Fig. 22).
Check to make sure the adjustments have not
changed and the bearing guides do not pinch the
blade.

Lower Bearing Adjustments
Unplug the machine from power
source before making any adjustments! Blade
teeth are sharp - use care when working near
the saw blade. Failure to comply may cause
serious injury.
Note: Blade tension must be properly adjusted
prior to bearing guide setup. Refer to the Adjusting
Blade Tension section.
Referring to Figure 23:
1. Loosen the thumb screw (B).
This will allow the thrust bearing (A) to move
freely and prevent interference with the saw
blade (C) during the following steps.
Guide Gearings Adjustment
2. Loosen the locking handle (D) then turn the
adjustment screw (E) to adjust the assembly
forward or backward until the front of the guide
bearings (F) rest just behind the gullet of the
blade teeth (C and inset).
3. Tighten the locking handle (D).
Thrust Bearing Adjustment
4. With the thumb screw still loose (from Step 1),
slide the thrust bearing and bearing post until
the space between the bearing (A) and the
back edge of the blade (C) is approximately
1/64”.
A convenient way to achieve this spacing is by
placing a dollar bill folded twice (four
thicknesses) between the blade and support
bearing – four thicknesses of a dollar bill is
approximately 1/64”.
5. Tighten the thumb screw (B).
4. Loosen the lock knob (G). Rotate the
adjustment handles (H) until the guide bearings
(F) rest lightly against the blade (C). Do not
force the guide bearings against the side of the
blade.
5. Tighten the lock knob (G).
Check to make sure the adjustments have not
changed and the bearing guides do not pinch the
blade.

Blade Lead
Blade drift (also known as lead or fence drift) is a
problem that may occur when the blade begins to
wander off the cutting line even when the band saw
fence is being used. Figure 24 shows an example
of blade lead.
Blade lead can be caused by a number of factors,
and these should all be checked and corrected if
necessary:
Fence is not parallel to miter slot and
blade.
Blade is not tensioned correctly.
Blade is dull.
Teeth have too much “set” on one side of
the blade.
If replacement of the blade is not currently an
option, the blade lead can be compensated for by
skewing the fence. Proceed as follows:
1. Cut a scrap piece of wood about the same
length as the band saw table, and joint one
edge along its length, or rip it on a table saw to
give it a straight edge.
2. Draw a line on the board parallel with the
jointed, or straight edge of the board.
3. Move the band saw fence out of the way, and
carefully make a freehand cut along your drawn
line on the board. Stop about midway on the
board, and shut off the band saw (allow the
blade to come to a complete stop) but do not
allow the board to move.
4. Clamp the board to the table.
5. Slide the band saw fence over against the
board until it contacts the straight edge of the
board at some point. Lock the fence down.
6. Loosen the four hex cap screws at the top of
the fence (see Figure 9) and shift the fence
until it is parallel to the board along its length.
7. Re-tighten the four hex cap screws.
Note: Skewing the fence to correct blade lead is
effective for that particular blade; when a new blade
is installed, the fence will probably need re-
adjustment.

Replacing the V-Belt
Disconnect machine from
power source before making any adjustments.
1. Release blade tension as described in the
Blade Tension section.
2. Release belt tension by loosening the two hex
cap screws (A, B, Fig. 25). The pivot bolt (B) is
not visible.
3. Raise the motor and place a block of wood
under the motor to take the tension off the belt.
4. Open the lower wheel door (C, Fig. 26) and
remove the hex nut and washer (D, Fig. 26).
5. Remove the wheel (E, Fig. 27). If the lower
wheel does not come off easily you may need
to use a pulley puller to remove it.
Note: If you are doing a pulley alignment only, skip
Step 6.
6. Remove the old belt (F, Fig. 27) and install the
new belt.
7. Since the wheel is still off, this is the most
convenient time to check the wheel and motor
pulley alignment. Jump to the Pulley Alignment
procedure (following page) at this time. At the
conclusion you will be redirected back here.
8. Reinstall the lower wheel, hex nut and washer
and tighten the hex nut.
9. Remove the wood block or support from below
the motor.
Important: Before operating the band saw, refer to
the sections listed below and perform the required
adjustments described in them.

Belt Tension
The drive belt and pulleys are properly adjusted at
the factory. However, belt tension should be
occasionally checked. The belt will need to be re-
tensioned after belt replacement.
Disconnect machine from
power source before making any adjustments.
1. Release belt tension by loosening the two hex
cap screws (A, B, Fig. 25). The pivot bolt (B) is
not visible.
