Assembly
The assembly instructions describe mounting the Single-Needle Sewing Machine (Model
92966) to the Table Stand (Model 03929), not included. In order to complete this procedure,
you must first purchase and assemble the Table Stand Kit (Model 03929).
1. Locate four corner rests in the rectangular hole of the Table Stand where the machine
will sit.
2. Place two rubber seats (A) on the operator-side and secure with supplied hardware (C).
See figure 1.
3. Place two rubber hinge rests (B) on the hinge-side and secure with supplied hardware
(C).
4. Seat the Oil Pan (D) on the corner seats (A). See figure 2.
5. Insert Hinges (E) into the machine bed. See figure 3.
6. Fit the machine head’s hinges to the rubber hinge rests (B) before placing the machine
head on the corner seats. See figure 4.
For technical questions, please call 1-800-444-3353.

7. Tilt the machine back to expose the Oil Pan (D). See figure 5.
8. Fill the Oil Pan with sewing machine lubrication oil (#7 white oil) to the “high” mark “A”.
Add more oil when the level is to the “low” mark “B”. After lubrication, and during operation, oil splashing can be seen through the Oil Sight Window (H).
9. Lower the machine head to the table top.
10. Mount the Motor to the underside of the table top as shown below. Use the supplied
hardware.
Note: Top switch
determines rotation.
Switch left for counterclockwise; switch right
for clockwise rotation.
No te: Motor is 110/ 220V
Single Phase. Disconnect
pow er an d flip sw i t ch to
desired voltage. Switch left
for 110V, swit ch r ight for
220V. For 220 V, the power
plug must be rewired by a
qualified technician.

around the Motor pulley. Attach the Pulley Safety Cover.
12. Tighten the V-belt tension by adjusting the long bolt and nut at location (K). The proper
tension is reached when the V-belt can only be deflected 1/2 inch.
13. Mount the Power Switch under the table top, on the operator’s side. Use the supplied
hardware.

Mounting the Thread Stand
Note: The Thread Stand is designed to be mounted on the Table Stand Kit (Model
03929 - not included). Unless indicated otherwise, all parts referred to
in this set of instructions are listed in the Bobbin Winder & Thread Stand
Unit Parts List found on page 23. During assembly, it will be helpful to
refer to that list and the diagram above it on the same page.
14. Locate the large hole in the far right corner (from the location that the operator will be
seated) of the Table (not included). Place the Rubber Washer (10-41) and Washer
(10-33) onto the Lower Spool Rest Rod (10-32) and insert the Rod into the hole mentioned
above. Place another Washer (10-33) over the end of the Rod, and thread on and tighten
a Nut (10-34).
15. Place the Spool Support (10-42) over the Lower Column (10-32) about halfway down.
Insert a Screw (10-27) and Nut (10-43) through the Support.
Note: The Support has tabs that hold onto the corners of the Nut to make tightening
easier. When assembling, place the Nut on the side with these tabs.
Tighten the Screw.
16. Insert the threaded end of the Spool Pin (10-36) through one of the holes in the top of
the arm of the Spool Support (10-42). Place a Washer (10-28) and Nut (10-31) over
the end of the Pin and tighten. Place the Spool Rest (10-37), Spool Mat (10-38), and
the Spool Vibration Stopper (10-35) over the end of the Spool Pin. Repeat this step for
both of the Spool Pins (10-36).
17. Place the Column Pipe Connector (10-29) over the top of the Lower Column (10-32)
until the Rod is about halfway through the Connector. Place a Screw (10-30) and Nut
(10-31) through the bottom hole in the Connector and finger-tighten.
18. Place the Upper Spool Rest Rod (10-26) into the top of the Column Pipe Connector
(10-29). Place a Screw (10-30) and Nut (10-31) through the top hole in the Connector.
Tighten all of the Screws and Nuts in the Connector.
19. Place the Thread Hanger (10-24) about halfway over the top of the Upper Column
(10-26). Insert a Screw (10-27) and Nut (10-43) through the Hanger as explained in the
note in step 14, above. Tighten the Screw and place the Column Cap (10-25) over the
end of the Upper Column (10-26).

Mounting the Bobbin Winder
Note: Unless indicated otherwise, all parts referred to in this set
of instructions are listed in the Bobbin Winder & Thread
Stand Unit Parts List found on page 23. During assembly,
it will be helpful to refer to that list and the diagram above
it on the same page.
20. Remove the Belt Cover (part 8-27, on page 21). Swing the
sewing machine so the base is in the operating position,
resting on the table. Set the Bobbin Winder to the ‘ON’
Position-see ON Position, below.
21. Make sure the Bobbin Winder is in the ‘ON’ position.
Position the Base (Bobbin Winder Base Assembly) (10-1)
so that the Thread Winder Assembly (10-4) lines up with
and just touches the belt. Mark pilot hole locations on the
table at the far end of each of the two channels in the Base
as indicated in Figure A.
22. Set the Base (10-1) aside and swing the sewing machine
out of the way. Carefully drill straight pilot holes for each of
the two locations marked above. Place the base in location
and secure using two Wood Screws (10-22) and Washers
(10-23). Leave the Screws just loose enough to allow the
Base to slide.
