WARNING
Wear eye protection.
Use the saw blade guard and spreader for every operation for which it can be used, including all
through sawing.
Keep hands out of line with the saw blade.
Use a push stick when required.
Pay particular attention to instructions on reducing the risk of kickback.
Do not perform any operation freehand.
Never reach around or over the saw blade.
1. Read and understand the entire instruction manual before attempting assembly or operation.
2. This table saw is designed and intended for use by properly trained and experienced

complete stop.
19. Read and understand warnings posted on the machine.
20. Use blade guard for every applicable operation including all through cuts. If guard is removed for
special non-through cuts such as dado and rabbet cuts, replace before further use of the saw.
21. Failure to comply with all of these warnings may cause serious injury.
22. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead based paint
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from those exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specifically designed to filter out microscopic particles.
23. Do not operate tool while under the influence of drugs, alcohol or any medication.

Introduction
The JET JTAS-10XL or JTAS-12XL tablesaw you have purchased is a high quality machine tool that will
give you years of superior service. You will get maximum performance and enjoyment from your new
table saw if you will take a few moments now to review the entire manual before beginning assembly and
operation.
This tablesaw, as well as all JET products, are backed by a nationwide network of authorized distributors
and/or service centers. Please contact your nearest distributor should you require parts or service. Parts
are also available directly from WMH Tool Group by calling 1-800-274-6848.
Now that you have purchased a tablesaw, it is a good time to consider a dust collection system. See
your local JET distributor for the complete line of dust collectors and the full line of JET Dust Collector
Hoses and Accessories. Customize your installation and obtain maximum performance with JET's dust
hoods, hoses, clamps, fittings, and blast gates.
Assembling and fine tuning a tablesaw, fence and rail system, extension tables, etc. can be a time
consuming project. It is best not to rush. The tablesaw does not come with a plug. Purchase a plug that
matches the 230V or 460V outlet that will be used. The tablesaw does not come with a blade so you
may want to purchase a variety of blades for different applications.

3. When saw blade is aligned with the splitter,
carefully tighten the hex cap bolt on the
bracket assembly inside the saw.
4. Make sure the splitter is level with the table
and approximately 1/8" above the table
before tightening the hardware on the rear
of the blade guard assembly. Space
between the splitter and the table keeps the
splitter from binding on the table when the
blade is tilted to 45°.
5. When saw blade is aligned with the splitter,
lower the blade, and tighten all hardware
6. Check alignment again after tightening
hardware. Adjust if necessary.

10

turning four leveling screws (A, Fig. 9) and
using a straight edge.
Mounting Rails & Extension Table
With the extension wings properly aligned, the
rail and fence assembly can now be mounted to
the saw. See the Owner’s Manual for the
XACTA Fence Assembly Instructions. This will
address the mounting of the table, switch, rails
and fence.
Attaching the Switch Bracket Assembly
and Switch Brace to the Saw
• Hardware: Switch Brace
• Tool: 8mm HexWrench, 8mm Wrench
1. Place switch bracket assembly behind both
the front fence rail and the lip of the left
extension wing. (Do not place between the
front fence rail and the extension wing - this
will cause the front rail to distort and the
fence to bind).
2. Loosen (do not remove) hex socket cap
screw (A, Fig. 10).
3. Slide the open tab of the switch brace onto
the hex socket cap screw and washer.
Hand tighten only at this time.
4. Remove the nut and star washer from the
screw at the bottom of the switch plate.
5. Fasten the switch brace to the switch
bracket assembly with the star washer and
nut.
6. Align the switch and tighten all hardware.

1. Operate miter gauge by loosening lock knob
(A, Fig. 11) and turning miter body (B, Fig.
11) to desired angle. To move gauge
beyond index stops of 45°and 90°, flip
down stop (C, Fig. 11).
2. Adjust index stops by turning one of three
adjustment screws (D, Fig. 11).
Note: Always make test cuts. Do not rely solely
on miter gauge indicator marks. There are
holes in the miter gauge body that will allow you
to mount a wooden extension fence.

11
Blade Raising and Tilting Mechanism
1. To raise or lower the saw blade, loosen the
lock knob (A, Fig. 12) in the middle of the
handwheel and turn the handwheel (B, Fig.
12) on the saw front until desired height is
reached. Tighten lock knob. The blade
should be adjusted 1/8" to 1/4" above the
top surface of the material being cut.
2. To tilt the saw blade, loosen lock knob (C,
Fig. 12), turn handwheel on the right of the
saw cabinet (D, Fig. 12) until desired angle
is obtained, then tighten lock knob.

injury!
The JTAS-10XL-1, JTAS-10XL-5/1 and JTAS-
12XL-5/1 table saws are rated at 230V only.
The JTAS-10XL-3 and JTAS-12XL-3 are rated
at 230/460V, and come from the factory
prewired 230V.
To switch the JTAS-10XL-3 and JTAS-12XL-3
from 230V to 460V:
1. Disconnect the machine from the power
source, (unplug).
2. Open the saw cabinet door.
3. Remove the cover from the motor junction
box.
4. Change wires following the diagram on the
inside of the cover.
5. Replace the cover and close the cabinet
door.
6. Replace the magnetic on-off switch with part
#JTAS10-23B (available through your
authorized JET distributor or by calling
WMH Tool Group at 1-800-274-6848).
Confirm power at the site is the same as the
saw before making any electrical connections.
Review the electrical schematics on page 32-33.
The on and off switch is thermally protected.
If the saw motor is overloaded, or a momentary
interruption of electrical current is sensed, the
saw will shut off. Allow a few minutes for the
saw to cool down and reset by pushing the off
button.
Using extension cords can cause a loss in power
to your machine. It is best if the saw is plugged

Blade Alignment
• Tool: 8mm Hex Wrench, combination square,
marker
Blade alignment with the table is adjusted at the
factory. After a period of use, or, after moving
the saw to another location, the blade may no
longer be aligned with the table. To check and
align the blade: see Figure 13
1. Disconnect the saw from the power
source.
1. Raise the blade guard up and out of the way
of the blade.
2. Unlock fence and move away from the
blade so as to expose the right T-slot.
3. Choose a tooth on the far side of the blade
and directly over the insert. Mark the tooth
with a marker. Measure the distance from
the side of the blade to the right T-slot edge
using a combination square. Make sure to
measure between the teeth not on the tooth,
Figure 13.
4. Rotate the blade toward the front so that the
marked tooth is just above the insert.
Measure the distance from the side of the
blade to the right T-slot edge. The two
measurements should be the same.
5. If they are not the same, loosen four hex
socket cap screws (A, Fig. 14) that hold the
table to the base. Two are shown in Figure
14.
6. Make the needed adjustments and tighten
the four hex socket cap screws firmly.
7. Check the alignment once again after
tightening hardware.

13
Adjusting 45°
°°
°and 90°
°°
°Positive Stops
The stops have been adjusted at the factory.
After a period of use, or, after moving the saw to
another location, the stops may no longer be set
properly. To check and adjust the stops:
• Tool: 12mm Wrench, combination square
1. Disconnect saw from power source.
2. Raise the saw blade to its maximum height
using the handwheel.
3. Set the blade at 90 degrees to the table by
turning the blade tilting handwheel
clockwise as far as it will go.
4. Place a square on the table and check to
see that the blade is at a 90°angle to the
table, Figure 15. Make sure square is not
touching a blade tooth.
5. If blade is not at 90 degrees, open the motor
cover door, loosen lock nut (A, Fig. 16) and
turn adjusting stop screw (B, Fig. 16) on the
front trunnion in, or out. The adjusting stop
screw should stop against the front trunnion
bracket when the blade is 90°to the table.
6. Tighten the lock nut (A, Fig. 16).
7. Set the blade at 45 degrees to the table by
turning the blade tilting handwheel counter-
clockwise as far as it will go. Place a
square on the table.
8. If the blade is not 45 degrees, remove the
raising and lowering handle. Loosen lock
nut (A, Fig. 17) and turn adjusting stop
screw (B, Fig. 17) on the front trunnion in, or
out. The adjusting stop screw should stop
against the front trunnion bracket when the
blade is 45°to the table.
9. Check the accuracy of the pointer (C, Fig.
17) on the angle scale and adjust, if
necessary.
Assembly and adjustment of the saw are now
complete. Make sure all fasteners are tight.
