1. General Observaon of the Front Frame Cover, Mast and Hand Wheel
The following observaons, accompanied by
necessary adjustments, will ensure trouble-free
thread passage. Failure at any of these points will
signicantly aect thread tension.
Check:
1. The thread mast should be adjusted so that the
eyelet loops are centered directly over the spool
pins.
Note: The thread mast has two lile balls that fall
into detents/holes when aligned. These help keep the
eyelet loops aligned over the center of the spool pins.
If a correcon is necessary: Loosen the screw on the
boom of the thread mast. Make sure both detent
balls are in their locater holes, rotate the enre
thread mast by turning the vercal mast support
unl the top eyelet loops are directly over the spool
pins. If the thread mast is too ght inside the bracket,
remove the screw, push the mast out of the bracket
unl you can rotate the eyelet loops to be directly
over the pins while the detent balls are in their locater
holes. Reghten the Phillips head screw rmly into
the boom of the thread mast support. (#2 Phillips
screwdriver)
Check:
2. Make sure that a gap of 1.0 mm to 3.0 mm exists
between the frame and the hand wheel. (Note:
The hand wheel screw is inside the front cover and
cannot be seen from the outside of the machine,
therefore it can only be adjusted with the front
cover removed.)
If a correcon is necessary:
(Usually this would only be necessary if the hand
wheel is rubbing, has an extreme gap or is loose.)
Remove the front cover (see removing front cover),
loosen the hand-wheel set screw, posion the hand
wheel and re-ghten the set screw. (3 mm handle hex
tool)

Figure 1.4
3. Check/Inspect: Test the condion of the thread
guides, the takeup/check spring, the take-up
lever, the thread srrup and the needle bar
thread guide. Check for any abrasions, cuts, or
electroplang blistering. Test each guide by ossing
it with thread, le to right and front to back in all
direcons, checking for any sharp defects that may
damage or cut the thread. Replace any damaged
parts.

4 mm L hex tool, #3 at screwdriver.)
Cauon: Make sure the machine is unplugged from
the wall before removing the machines front cover.
1. Loosen the small set screw on top of the front
cover (posion A) Rotate the 3-hole thread guide
to allow access to the frame screw behind it, then
re-snug the screw so the guide will not become
misplaced. (2 mm handle hex tool)
2. Remove the three smaller circled frame screws
near the needle (3 mm handle hex tool)
3. Remove the other 10 front cover screws. (4mm
handle hex tool; you may need an L hex tool to
loosen them rst.)
4. Remove the two screws from the needle plate
and then remove the needle plate. (# 3 at
screwdriver)
5. Swing the front cover away from the rear casng,
starng at the front needle end of the machine,
and hinging from the hand wheel end of the
machine.
6. Before removing any cables from the control board
properly ground the machine and put on a ground
wrist strap.
7. Carefully remove the following 7 cables from the
control board: control board red/black power
cable, main sha encoder cable, motor driver
board cable, two handle bar cables, remote power
cable, and light ring cable. Note: the tension cable
remains connected to front cover with the control
board.

Apply one drop of Lube #6 (Purple), to the
raceway of the bobbin case support two to
three mes per day. This applicaon is based
upon sewing for eight hours of machine me.
If the machine is used less, lubricate the
hook less frequently. Aer the lubricaon
of the hook, it is recommended that one
momentarily sew on scrap material before
resuming the sewing of the quilt. Failure to do
so may result in oil stains on the quilt.
3. Lubricaon
Use Lube #1 (Red) in the seven places shown below, on each side of the sha between the bearing
and the sha. Then use Lube #2 (Blue) between the bearing outer diameter and the bearing
support at each of the seven places.

4 Checking and Securing Flats and Screws
Figure 4.1
Figure 4.2
The Quilt Maker Pro 18 VERSA has been designed using ats and special screws to help prevent loop li ming from
slipping, except at the hook. (If the hook cannot slip then something has to break when something goes wrong. The
hook is designed to be adjusted without removing the front cover.)
First check the torque specicaons chart on page 5,
then check the following locaons, making sure that
the rst screw of a med component has been xed
rmly on the respecve at on the sha:
1. The Pitman crank (Figure 4.1) (# 5 at screwdriver
2. The take-up lever driving link, (Figure 4.1) (3 mm
handle hex tool)
3. The main sha ming pulley (Figure 4.3) (2.5 mm
handle hex tool)
4. The hook-sha ming pulley (Figure 4.5 on page
13) (2.5 mm handle hex tool).
Note: The screws are generally posioned 120 degrees
apart. When the rst screw (Posion 1) has been
located and ghtened on a at, the second screw is then
ghtened, compounding the ghtness of the rst screw,
thus securing and assuring that ming will not change.
Note: The main-sha thrust collar has been replaced with
a brass counterweight which is no longer located on a at.
Note: It is important to check that the brass counterweight
ghtening procedure did not create a ght arm sha
condion. If so, readjust the counterweight again unl
there is no ghtness and minimal-to-no end-play. This is
checked by rotang the sha and checking a few mes
through a full 360° rotaon of the sha.
Counterweight Timing
Set counterweight ming as follows.
First Pitman screw up, edge vercal and aligned with
lier arm. At this posion, the counterweight chamfer
(the bevelled edge) always goes to the le side next to the
bearing and the slit is straight down with screws on boom
straight out at you (Figure 4.2).
The counterweight has a slit and can be adjusted. It is not
set on a at for ming.

Tools needed: (2.5 mm handle hex tool)
Note: The hook-sha ming pulley rotates the
opposite direcon as the main sha ming pulley.
Carefully note the labeled rst screw (Figure 4.5).
Note: The hook-sha collar does not have a at.
The at is located on the hook-sha ming pulley
rst screw.
Important Hook-Sha Notes
The hook-sha turns two mes per stch and rotates
in the opposite direcon as the main sha. Please
carefully note which screw is the rst screw in the
direcon of moon and on the at.
The hook-sha pulley is set to a specic seng from
the end of the sha to allow proper needle-to-hook
distance adjustment. Adjust the collar to remove axial
play, not the hook-sha pulley, or the seng can be
thrown o, which may make it so needle-to-hook
distance cannot be adjusted.
The QMP 18 VERSA ulizes long collars with two
screws in line to help prevent the collar from pping
when ghtened, causing variaon of ghtness or
play, as the collar rotates 360º. To ensure that there
is no ghtness or play, the collar should be checked
through a full rotaon unl it has minimal ghtness
and minimal play.
4. Checking and Securing Flats and Screws - Connued
First Screw, First Posion Rule
The rst screw or rst posion is almost always*
located 120° apart in the direcon of rotaon from
the second screw or second posion. The rst screw
in direcon of rotaon goes on the at. (Figure 4.4)
* (The pitman screws are only 90 degrees apart
instead of 120 degrees.)

Note: First screw in direcon of moon goes on the
at. The rst screw is 120º before the 2nd screw. The
2nd screw is then 240 degrees before the 1st screw.

5. Axial Play Check and Adjustment
Axial or end play on shaing can result in noise, wear
and faulty sewing.
Check:
1. Check the main-sha by pushing and pulling on
the hand wheel. (Figure 5.1) Note: A small amount
of main sha axial play is permissible. Too much
main sha play, however, may cause noise and or
stching issues.
Remove play here
Test le to right
If a correcon is necessary:
• Remove the front cover.
• Loosen the counterweight screws
(3 mm handle hex tool) (Figure 5.2).
• Adjust so that minimal to no play is detected.
• Provisionally set the screws.
• Check that the sha has minimal play and no
ghtness from the collar being too ght by
rotang the sha through a few 360o rotaons.
• Check that the ming of the eccentric is sll
correct (see counterweight ming Secon 4 page
12, gure 4.2.
• Fully ghten the screws.
• Check sha again for play or ghtness.
2. Check the hook sha by pushing and pulling the
hook as shown in (Figure 5.3).
If a correcon is necessary:
• Remove the front cover.
• Remove the play by loosening the hook-sha
thrust collar (not the hook-sha ming pulley)
and adjusng out any axial play (Figure 5.4). Note:
There is no at for the hook-sha thrust collar.
• Check for proper seng by rotang sha through
a few 360o rotaons.

feet will sit at on a planed surface. Note: This is
done on a precision surface plate at the factory
during assembly.
If a correcon is necessary: Thin shim washers may be
used as shown in (Figures 6.1 and 6.2).

7. Adjusng the Motor Drive/Timing Belt Tension
The Quilt Maker Pro 18 VERSA machine ulizes a
single motor drive/ming belt system.
Tools required: 3 mm handle hex tool, 0. 5 mm feeler
gauge, 8 mm open end wrench Tools required: 4 mm
handle hex tool
Check: With the machine front cover removed. Check the belt
tension for tautness by pressing it with the index nger (Figures
7.1–7.2). Press the vercal center of the belt with approximately
2 lbs of pressure. The belt should deect about ½”. Proper
belt tension provides for some belt exibility under light nger
pressure, but should not be so ght as to bind the machine.
Double-check the tension by rotang and rocking the hand wheel.
Conrm that there is no backlash or play between the belt teeth
and any of the driven components. Conrm also that there is an
immediate transfer of moon to all components driven by the
belt, from the handwheel to the hook.
Important: Do not over-ghten the belt as this will make the
machine too ght, the handwheel more dicult to turn, create
more belt noise, and also cause other undesirable issues.
If a correcon is necessary:
• Insert a 4 mm handle hex tool through the hole in the main
frame casng (Figure 7.2). Loosen the socket-head belt tensioner
screw. Adjust the belt tensioner by pressing down on the
tensioner and while holding down on the tensioner re-ghtening
the belt tensioner screw
(Figure 7.2).
• Note: This adjustment can only be made with the front cover o
so the tensioner can be pressed down to set proper belt tension.
Important: Do not aempt to set belt tension with the front
cover on as improper belt tension will result.
Important Note: Ensure that the special washer with step is
down into the tensioner bracket slot and at, not lted, when
ghtened, so the tensioner will not slip, resulng in a loose belt
(Figures 7.3-7.6).

8. Adjusng the Hopping Foot Adaptor
The Quilt Maker Pro 18 VERSA features the “KineQuilt”
hopping mechanism, allowing the hopping foot to move
(hop) up, down and dwell on the fabric when the needle
is in the fabric.
This allows fabric to move through the machine similar
to a normal sewing machine with a feed dog. The dwell
me allows for a longer hesitaon of the hopping foot
on the fabric and compleon of the stch cycle. The
results are beer tension, less needle breakage and
increased hook life.
The factory default for the boom of the presser bar,
without a hopping foot or mount adaptor, should be 1.5”
above the needle plate when the needle is in the lowest
posion.
Check:
With the hopping foot mount adaptor screwed into the
presser bar 13 tuns there will 6 or 7 threads exposed
below the foot adaptor jam nut. Check the number of
exposed threads below the jam nut to conrm it has
about this number. If it does not have 6 or 7 exposed
threads, this will alert you that someone has adjusted
the adaptor in or out. This may cause too much or too
lile tension on the internal presser bar spring.
Important: If there is improper spring tension on the
presser bar the result will be stch problems, including
skipped stches.
Important: Check and adjust this if necessary before
adjusng the presser bar height internally on screw C in
the next secon.
Adjust if Necessary:
Tools required: 8 mm open end wrench
1. Aach the hopping foot to the foot mount adaptor.
This helps you align the foot to the needle in the nal
step. Important: to prevent needle plate damage make
sure the foot does not touch the needle plate when
rotang the foot.
2. Loosen the jam nut with the 8mm open-end wrench.
3. Screw the mount adaptor unl there are 6 or 7
exposed threads below the jam nut when ghtened.
4. While holding the foot rmly, ghten the jam nut
while making sure the hopping foot ring is centered on
the needle.

9. Adjusng the Presser Bar Height (Internal Adjustment)
Tools: 3mm Handle hex tool, 0.5mm feeler gauge
Important: Make sure the hoping foot adaptor was
set correctly in the previous secon before doing this
step.
Check
When the needle bar is in its lowest posion, the
hopping foot should be no higher than 0.5mm above
the needle plate. It is permissible for the hopping foot
ring to lightly touch the needle plate.
1. Turn the handwheel unl the needle bar is at its
lowest posion.
2. Place the 0.5mm feeler gauge (part# QM40133)
under the hopping foot with the printed edge up.
3. Loosen screw C through the machine front cover
access hole.
4. Wiggle the presser bar up or down to the desired
posion.
5. Tighten screw C while pushing down lightly on the
tool blade toward the table while ghtening. This
ensures that the hopping-block mechanism contacts
the appropriate liing lever and eccentric inside the
machine.
6. Conrm the ring of the foot is centered on the
needle when the screw is ghtened.
Warning: if the jam nut is not properly ghtened the
hopping foot may become loose and be hit by the
needle causing serious machine problems.

Figure 10.2
GD
The needle posion adjustment is the most important
of all adjustments in the machine. Needle posion
provides the foundaon for which all other sengs
are made.
Once the needle posion has been completed, great
care must be maintained to keep this seng. It is
important that the sewing machine be transported
carefully, so as to not allow bumping or dropping.
Check:
• Use a new System 134/Size 100 needle. Check the
needle for straightness on a at surface such as the
needle plate. The needle must be centered in the
stch hole of the needle plate as shown in (Figure
10.1.) 2 mm and 3 mm handle hex tool
Check with needle eye ush with the needle plate,
not with the needle in the lowest posion.
Adjustment for Y axis: Cover O
Note that adjustment is done with the front frame
cover o.
If a correcon is necessary:
• Loosen rst screws D and G (Figure 10.2)
• Loosen screw A and screw B (Figure 10.2)
While pushing the head frame back into the main
casng, gently slide the head frame le or right to
correct as necessary.
• Tighten screws A and B in Figure 10.2.
Note: If needle posion changes, repeat the process.
Do not ghten screw D or G at this me.

Adjustment for X axis: Cover On
Note: That adjustment is done with the front frame
cover on. Important Note: The picture shows the
cover o for illustraon purposes only!
The primary adjustment is accomplished using the
right side of the head frame shown in (Figure 10.3).
The screws on the le side are loosened to allow
movement of the head frame.
If a correcon is necessary:
• Loosen screws F, G and H through access holes
(Figure 10.4) 2 or 3 turns.
• Loosen screws D and E 2 or 3 turns and back o
screw C a lile.
• Push the head frame back against the main frame so
that screw C touches the main frame. Adjust screw
C to bring the needle to center in the needle plate.
• Gently ghten screw E unl it lightly touches the
main frame
• Tighten screw D. Note: If the needle changes, repeat
the process.
• Repeat the process on the le side of the head
frame. Note: If the needle changes, repeat the
process.

11. Timing - Checking Loop Li and Needle Distance
Important Note: The ming and needle distance adjustment
must be done with the front machine cover on.
“Loop Li” is a universal hook and ming term for all lock-
stch sewing machines. When the needle lis a specied
distance from the BDC (boom dead center), the hook point
is set to coincide with the needle as shown in (Figure 11.1)
This is the radial posion of the hook called “Loop Li”,
commonly referred to as ming. Another part of ming is the
“Needle Distance” This is the axial distance from the hook
point to the needle. Loop li is the radial seng of the hook
and needle distance is the axial seng of the hook. Both of
these are set on the hook and xed with the same set screws.
Since two things are being set at the same me, this can be a
lile dicult unl pracced.
Tools required: Loop li clamp part #QM40199,
2.2 mm forked feeler gauge part #QM40136, 2
mm ball end L hex tool wrench, 2 mm handle hex
tool and a #3 at screwdriver.
Check: Observe and do the following before
aempng to make a hook ming adjustment.
1. Remove the needle plate.
2. Turn the hand wheel unl the needle bar is at its
lowest posion or BDC (Boom Dead Center)
3. Place the loop li clamp (with special protecve
compression pad) on the needle bar and set the
thumbscrew lightly.
4. Place the 2.2 mm feeler gauge between the clamp and the
boom of the head frame bearing surface (Figure 11.1).
5. Raise, reset and ghten the clamp, pinching the 2.2 feeler
gauge in between the clamp and projected bearing. This step
may need to be repeated a few mes to remove all excess
play between the clamp and gauge.
6. Remove the 2.2 feeler gauge (Figure 11.2)
7. Rotate the handwheel in direcon of moon (DOM); is very
important, unl the clamp lightly touches the gauging surface.
(Figure 11.3). Important: If the handwheel is turned too hard the
clamp may move, making the check invalid.
8. Check the radial posion of the hook point relave to the
needle. (Figure 11.4)
9. Check the axial distance between the needle and the hook
point. The hook point should lightly touch (brush) the needle
inside the scarf. Too much needle distance may cause shredding or
skipped stches.
