Warnings
1. Read and understand the entire owners manual before attempting assembly or operation.
2. Read and understand the warnings in this manual. Failure to comply with all of these warnings may
cause serious injury.
3. The table saw and tenoning jig is designed and intended for use by properly trained and experienced
personnel only. If you are not familiar with the proper and safe operation of a table saw or
tenoning jig, do not use until proper training and knowledge have been obtained.
4. Do not use the tenoning jig for other than its intended use. If used for other purposes, WMH Tool
Group disclaims any real or implied warranty and holds itself harmless from any injury that may result
from that use.
5. Always wear approved safety glasses/face shields while using this tenoning jig. Everyday eyeglasses
only have impact resistant lenses; they are not safety glasses.
6. Before operating the tenoning jig, remove tie, rings, watches and other jewelry, and roll sleeves up
past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor
strips are recommended. Do not wear gloves.
7. Wear ear protectors (plugs or muffs) during extended periods of machine operation.
8. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contain 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, cement and other masonry products.
Arsenic and chromium from chemically treated lumber.
9. Your risk of exposure 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 face or dust masks that are specifically designed to filter out microscopic
particles.
10. Do not operate this jig while tired or under the influence of drugs, alcohol or any medication.
11. Make certain the table saw or shaper switch is in the OFF position before attaching the tenoning jig.
12. Make certain the machine is properly grounded.
13. Make all machine adjustments or maintenance with the machine unplugged from the power source.
14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting
wrenches are removed from the machine before turning it on.
15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance
purposes, use extreme caution and replace the guards immediately.
16. Make sure the table saw or shaper is firmly secured to the floor or bench before use.
17. Check damaged parts. Before further use of the machine, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting
and any other conditions that may affect its operation. A guard or other part that is damaged should
be properly repaired or replaced.
18. Provide for adequate space surrounding work area and non-glare, overhead lighting.
19. Keep the floor around the machine clean and free of scrap material, oil and grease.
20. Keep visitors a safe distance from the work area. Keep children away.

21. Make your workshop child proof with padlocks, master switches or by removing starter keys.
22. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
23. Maintain a balanced stance at all times so that you do not fall or lean against saw blades, shaper
cutters or other moving parts. Do not overreach or use excessive force to perform any machine
operation.
24. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for
which it was not designed. The right tool will do the job better and safer.
25. Use recommended accessories; improper accessories may be hazardous.
26. Maintain tools with care. Keep saw blades or shaper cutters sharp and clean for the best and safest
performance. Follow instructions for lubricating and changing accessories.
27. Make sure the work piece is securely attached or clamped to the jig. Never use your hand to hold the
work piece.
28. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do
not use your hands.
29. Do not stand on the machine. Serious injury could occur if the machine tips over.
30. Never leave the machine running unattended. Turn the power off and do not leave the machine until it
comes to a complete stop.
31. Remove loose items and unnecessary work pieces from the area before starting the machine.

Assembly
Refer to Figure 1.
1. Insert the handwheel assembly (F) into the
clamp bracket (B) and secure with the lock
handle (A) on the clamp bracket.
2. Attach the clamp bracket (B) to the back of
the fence (G) using two M10 x 25 socket head
cap screws (D) and M10 lock washers (E).
3. Attach the handles (C) to the clamp
bracket (B).
Note: There are two slots on the underside of the
tenoning jig. For the JTSA-10XL, 66 and 64A JET
& Powermatic left tilt saws, mount the slide (H)
into the left slot (farthest from the fence). A 4 mm
hex wrench (provided) is required.
Figure 1
Alignment
Disconnect saw from power
source before making adjustments to the
tenoning jig.
To align the tenoning jig:
1. Place the jig guide into the saw's left miter
gauge slot.
2. Using a square (A, Fig. 2), check to see if the
fence is 90 degrees to the saw table. To
make an adjustment to the fence, loosen the
lock handle (B), adjust the fence to the
90-degree position and tighten lock handle.
3. When the fence is 90 degrees to the table,
tighten setscrew (C) until it bottoms. See
Figure 2. Setscrew (C) acts as a positive stop
and allows you to quickly position the fence
back to the 90-degree position after it has
been tilted.

4. Using a square (A, Fig. 3), check to see if the
position of the backstop (D) is 90 degrees to
the saw table. If not, loosen the lock handle
(E), adjust the backstop to the 90-degree
position, and tighten the lock handle.
5. When the backstop is 90 degrees to the table,
adjust the setscrew (F) until it touches the
backstop. Tighten the jam nut. Setscrew (F)
acts as a positive stop and allows you to
quickly position the backstop back to the
90-degree position after it has been tilted.
Figure 3
6. Loosen locking handle (G, Fig. 4). Loosen
thumbscrew (H) and move bracket (J) to the
back edge of the guide rod (K). The guide
bushing should move out with the bracket. If
the guide bushing does not move lubricate
with a light oil. Tighten locking handle (G),
and thumb screw (H).
7. To bring the fence into parallel with the saw
blade, loosen both locking handles (G, L). See
Figure 4. Reposition the jig so that the fence
lies flat against the saw blade and tighten both
locking handles.
Figure 4
8. The miter bar slots in the base are milled to
be parallel to the fence. If an adjustment is
necessary, loosen the two hex socket head
screws (A) holding the guide rod to the base,
as shown in Figure 5. Place the jig back into
the miter slot.
Loosen locking handle
(L Figure 4) and make the needed
adjustment. When adjustment is finished,
tighten the handle and remove the jig, and
fully tighten the screws under the guide rod.
Place the jig back on the saw with the miter
bar in the miter slot.
9. Loosen both locking handles (G & L, Fig. 4),
and back off jig so that the fence is
approximately 1/8" away from the saw blade
and tighten both locking handles (G & L).

10. To prevent the fence from being pushed, or
moved, into the blade, loosen the nut (N) on
the setscrew and turn the setscrew clockwise
until it bottoms out (Figure 6). Tighten down
the nut.
Figure 6
11. For a final adjustment, loosen screw (P)
holding the pointer and adjust pointer to the
1/8" position. See Figure 7. Tighten screw.
Operation
Use of the tenoning jig
requires removal of the table saw's blade
guard. After the jig operation is complete,
disconnect saw from power source and re-
install the blade guard immediately.
Figure 7
1. Use the handwheel (A) to tighten your
workpiece against the fence. See Figure 8.
2. Use the two large handles (B) to securely
move the workpiece through the saw blade.
3. NOTE: Never pass the jig back over the
moving saw blade. Wait until the power is off
and the blade comes to a complete stop.
4. For rapid or large adjustments moving the
fence toward or away from the saw blade,
loosen both locking levers (C, D). Move the
fence into position and tighten both locking
levers (C, D).
5. For fine adjustments moving the fence toward
or away from the saw blade, loosen both lock
levers (C & D). Move the fence away from the
saw blade and tighten lock lever (D) only.
Move the fence into position with knob (E) and
then tighten lock lever (C).

6. If it is necessary to cut a tenon on the side of
the workpiece that is against the fence, a
wood spacer must be secured between the
workpiece and the fence, as shown in Figure
9. This will keep the saw blade from hitting
the fence.
Note: There are four holes in the fence for
mounting a wood block spacer.
Figure 9
Angle Tenons
For angle tenons, loosen lock lever (F), shown in
Figure 10, and adjust the backstop (G) to the
desired angle. Re-tighten lock lever (F).
Figure 10
Figure 11 shows an angle tenon procedure with
the fence tilted. Loosen lock lever (H) to tilt the
fence.
This type of cut requires a
spacer (J) between the workpiece and the
fence in order to prevent the saw blade
coming into contact with the fence.
