The DeLuxe Stitcher M19 Stitcher Machine is a single-head stitcher designed
to accommodate both light and heavy-duty work, stitch both flat and saddle and is
recognized for being the perfect stitcher for the smaller bindery due in part to its 3/4”
(20mm) capacity and range of crown sizes.
The M19 accommodates both the Traditional Style 18D Head and the Side-Feed Style
G20 Stitcher Head. Because either Head can be used the recommended wire sizes for
the M19 are: 20 to 28 gauge round wire and 19x21-1/2, 20x 24 and 21 x 25 flat wire.
When ordering extra Heads, add the wire and crown size to the Head part number. For
example: G20BHD20241/2.
18001BHD ............................................................. M19AST and M19BST
G20BHD ........................................................ M19G20AST and M19G20 BST
The M19 is easily adjusted from saddle work to flat work by tilting the 5-1/2” (14cm)
x 26” (66cm) work table. An adjustable work guide and adjustable work stops are
easily attached to the work table and provide for accurate registering of flat work for
uniformly spacing the stitches. In addition a work table extension is provided to
accommodate larger format work.
The M19 is foot-switch operated and belt driven by a 1/2 HP motor, making possible
cycle speeds up to 200 stitches per minute. The motor is mounted on an adjustable
bracket which can be raised or lowered to adjust driving belt tension. The driving
mechanism is thoroughly shielded, preventing the possibility of personal injury.
The M19 has a 14” (36cm) throat depth for either flat or saddle stitching. The work
table is approximately 35” (89cm) above the floor and there is approximately 1”
(25mm) clearance between the top of the work to be stitched and the protective
guarding around the stitcher head.
The M19 weighs 369 lbs. (168 kgs) net and the shipping weight is approximately
396 lbs. (180 kgs). With the table installed, the M19 requires about 33” (84cm) x 29”
(74cm) of floor space.
Because of the length of the work table, the M19 must be secured to the floor to meet
CE stability requirements. Sound level readings at the normal operator position are
approximately 70 dB.

Some assembly is required upon delivery of the M19 Stitcher. You will need a flat screwdriver and a
9/16” open end wrench. Remove the packing materials from around the M19 and all contents from the
shipping boxes. Mount the Spool Bracket (G30144) to the outside of the Left Guard (G30143) with
two (2) Hex Head Cap Screws (UA1420.1), through two (2) Plain Washers (PW14.2) and two (2) Lock
Washers (LW14). Locate the Spool Stud (7693) and remove the Hex Nut (HN3816), Washer (PW38) and
Lock Washer (LW38) from the one end. Insert the threaded end of the Spool Stud into Spool Bar Bracket.
Replace the Washers and Hex Nut. Loosen the Thumb Screw (P2731) in the Set Collar (7691) to remove
it and the Tension Spring (7690) from the Spool Stud. Slide the Wire Spool over the Spool Stud, making

The plastic Belt Guard (7676) must be
removed before the M19 can be turned
over manually. To remove the Belt Guard,
remove the Retaining Screw (G30163)
from the top of the Guard (on BST mod-
els only). Press on one side tab while
prying out the locking face, at the top of
the Guard. Next, pull down
slightly on the top of the Guard to release
the bottom tab. The Guard will now be
free to lift off from around the Belt Guard
(7675).
To reassemble, interlock the bottom
tab and pull up slightly on the Guard to
interlock the side tab, then squeeze the
two halves of the Guard together to
lock the remaining tab. Reassemble
the retaining screw at the top of the
Guard (on BST models only).

sure that the Flat Washer (PG10271) is between the Spool and the Wire Spool Bracket. Also verify that the
wire payoff is identical to the payoff in Figure 1; from left to right. Improper wire payoff will result in
poor stitching. Slip the Plastic Washer (M11009) over the Spool Stud and replace the Tension Spring and
Set Collar. Apply slight pressure on the Set Collar, pre-loading the Tension Spring, then tighten the Thumb
Screw in the Set Collar until secured. Mount the Wire Guide Spring (15150A or G20286A) in the Wire
Guide Spring Bracket (15154 or G20278AA). A properly set Tension Spring will cause the Wire Guide
Spring to flex but not actually hit the wire spool. The Tension Spring is designed to prevent the Wire Spool
from over-running and tangling.
Loosen the two (2) Set Screws (38) in the bottom of the Complete Table Assembly (K1033)andpull
the two (2) Pins (203B) in the Table out to each side. Center the Table Assembly over the Clincher
Mount Assembly and make sure the Table Support (7648) is under the pin on the Table Support Bracket
(7645A). Push the two (2) Pins from the Table into the Mount Assembly until they click. Tighten the
two (2) Set Screws to further secure the Table to the M19. Make sure the Table converts from the flat
to saddle position when the Table Support Bracket is activated.
The Work Guide (M7201B) can be attached to the Complete Table Assembly with two (2) Work Guide
Screws (63). The two (2) Work Stops (7423) can be secured to the Work Guide by tightening the two
(2) Thumb Screws (425).

To turn the machine manually, it
is first necessary to disconnect the
power and remove the Belt Guard
(7676), see the section “Belt Guard
Removal” on page 8. Locate the
Actuator Assembly (850992) on the
Wrap Spring Clutch (850673 or
850674) and push the Actuator so
that it pivots away from the Control
Collar Cam (850888), releasing the
Brake Hub (850892). The machine
will rotate one revolution when the
Drive Pulley (7678) is turned
manually in the direction of the
arrow on the pulley.
Note: If stalling or hesitation occurs
during operation, the Belt may need
to be tightened.
To tighten the V-Belt (850730C)
first loosen, but do not remove, the
four (4) Hex Nuts (HN3816) on the Motor Mounting Plate (G30048). Tighten the four (4) Hex Nuts
again when the V-Belt is taut. If the Belt is not tight enough by force of gravity, wiggle both the Motor
Plate and Motor (on the other side of the Stitcher) slightly until it is. Do not press on the Motor arm to
make this adjustment as pressing on the Pulley may knock it out of position. The V-Belt should first
be tightened after two to three weeks of use and then periodically after that. Moisture, change in
temperature as well as wear can affect the tightness of the Belt. Loose Belts can cause the Stitcher
to stall and may damage the Belt permanently.
Note: Over tightening the Belt can damage the main bearing on the motor.

The quality and quantity of work that can be stitched on the M19 is dependent upon the operator
making the necessary operating adjustments as accurately as possible. The following information
and instructions are provided so that the operator will clearly understand how to make the required
operating adjustments.
Additional Operator’s Manuals for the stitcher heads supported by the M19 Stitcher are includ-
ed with the Stitcher itself. Please refer to these manuals for specific instruction and operating
adjustments for the individual stitcher heads.

Unlock the Hand Wheel (G30128) by
turning the Adjuster Crank (G30175) on
the Adjuster Crank Housing (G30099B)
counter-clockwise. Turn the Hand
Wheel clockwise until the Adjuster Spool
(G30119) is raised sufficiently to allow a
sample of work to be inserted between it
and the lower Adjuster Stop (G30103).
Note: A sticker located near the Hand
Wheel indicates the direction of opera-
tion.
The thickness gauge is located on the
right-hand side of the machine if you are
looking from the front of the stitcher. With
the work held flat in a horizontal position,
turn the Hand Wheel counter-clockwise
until the work is firmly clamped between
the Adjuster Spool and the lower Adjuster
Stop. Turn the Hand Wheel back clock-

The wire sizes that can be used on the M19 as well as recommended uses are listed below. Refer to
the Operator’s Manual for the Stitcher Head on your M19 when changing the existing wire size. The
Stitcher Heads are designed to accommodate a specific wire size. Wire gauges smaller than the
specific size for the stitcher head can still be used, but the maximum capacity for that head will not
be reached. For example, a 19x21-1/2 gauge wire head will function properly with 20x24 gauge wire
but the stitching capacity for the Head will drop from 3/4” to approximately 1/2”.
Refer to Figure 5.
Two types of Clincher Points are provided
with the head on the M19. When running
round wire, use the Clincher Points with part
number 7257B. When running flat wire, use
the Clincher Points with part number 7024B.
When stitching stock over 20# it is recommended that
a high tensile wire be used, which is available in
21x25, 20x24 and 19x21-1/2 flat wire sizes. The
high tensile wire may cause increased wear on certain parts.
For any stock over 33# or coated stock it is recommended that 19x21-1/2 flat wire be used. Refer to
Figure 6 for a general overview of suggested wire sizes to use for specific stitch capacities.

wise just enough to allow the work to be withdrawn from the Adjuster Spool, then return the Hand
Wheel to the setting at which the work was clamped.
Anytime the thickness of work changes, a sample should be tested in the M19 so no serious
damage is caused to the machine. If the machine is operated on work thicker than it is set to handle,
damage will result and the stitcher machine will not operate properly.

position. If it is not, tilt it back until the Table Support Bracket locks the Table into place. Loosen
and remove the two (2) 1/4-20x5/8 Screws (UA4810.5) securing the Clincher Guard (G30113) to
the Clincher Mounting Assembly (G30044A). Be careful to also remove the two (2) Lock Washers
(LW14) and Plain Washers (PW10). Check the Clincher Point height by cycling the machine
manually and stopping it at the top or highest point of Clincher activation. Loosen the Set Screw
(UA1428.1) in the Adjustment Block and rotate the Clincher Slide Adjustment Screw (18186), which
raises or lowers the Clincher Slide (18182), to adjust the Clincher Points as needed. Rotating the
Screw clockwise lowers the Points, while rotating the Screw counter-clockwise raises the Points.

Tighten the Set Screw and replace the Clincher
Guard with the Screws and Washers. Complete
the cycle of the machine and test a few stitches.
Repeat the previous steps if necessary.
If the stitch clinches properly but the legs are
angled away from its crown, the Clincher Plate
may not be aligned with the Stitcher Head’s
Driver. Refer to both Figure 7 and Figure 8
and the following instructions for directions on
centering the Clincher Points.
Coarse Adjustment
Although the Clincher Plate alignment is set
at the factory, it can be adjusted. With wire
threaded through the machine and the
compression set to 1/8” turn the machine over
manually, but stop as the staple begins to exit
the Bender Bar. Loosen the two (2) 1/2-20x1-
1/4 Screws (G30159) securing the Clincher
Mount Assembly (G30044A) to the M19 Frame.
Using this half-formed stitch, line up the legs of
the staple with the Clincher Points from back
to front as well as from side to side. Once the
legs of the staple are aligned, the Driver will be
centered above the Clincher Points and the quality of the stitch will be greatly improved. Tighten the
Screws to secure the Clincher Mount Assembly in this position. Complete the machine’s cycle and
remove the formed staple so as to not jam the Clincher Points.
Fine Adjustment
For fine adjustments, refer to the Stitcher Head’s Operation Manual. Specifically, refer to the
section of the manual which highlights making adjustments to the Leveling Screws on the back of
the Stitcher Head.

The Work Stops, which are included with all M19 Stitchers, ensure consistent placement of
stitches time after time. Both types of Stops available perform a different and specific function.
Use the Work Guide, set of Work Stops, or both depending on the application at hand.
Work Guide
The Work Guide (M7201B), sometimes referred to as the Back Guide, is controlled by two (2) Work
Guide Screws (63). The slots in the rear of the Guide allows free placement of the Stop. Slide the
Work Guide back and forth until the the location on the stock being stitched is under the Driver. Once
the ideal location is determined, the two (2) Work Guide Screws are tightened and the Guide is locked
into place. Two (2) Table Extender Brackets (7659) are attached to the Work Table Assembly (7656A)
for additional Work Guide placement. To use these extensions, loosen and remove the two (2) Work
Guide Screws and insert them in the Extender Brackets. Slide the Work Guide back and forth until
the proper stop location is found and tighten the Screws as before.
Work Stops
The two (2) Work Stops (7423), sometimes referred to as the Side Guides, are controlled by two (2)
Thumb Screws (425). Slide each of the two (2) Work Stops along the Work Guide until the desired
location on the stock being stitched is under the Driver. Once the perfect position is found, tighten
each of the two (2) Thumb Screws.

Troubleshooting
The following is a brief list of problems and solutions which should cover the majority of situations
encountered when stitching with the M19. The quality and quantity of work that can be produced with
the M19 Stitcher is dependent upon the operator making all adjustments as accurately as possible and
carefully maintaining the machine. The cause of staple imperfections usually can be traced to
inaccurate settings or normal wear of moving parts. In these events, the operator can quickly locate
the solutions, by referring to the following troubleshooting chart.
Note: Most stitch quality issues are addressed in the Stitcher Head manual.
problem:The machine will not complete a cycle, under power or manually.
solution:
1. Make sure the compression setting is correct. If not turn the Hand Wheel (G30128)
clockwise to raise the stitcher head.
2. If the V-Belt is too loose it must be tightened.
3. Make sure none of the Clutch Springs are broken and that the Clutch has not failed. If either
are the case, replace the component or the entire assembly.
problem:The machine will not begin a cycle at all.
solution:
1.MakesuretheInterlockSwitchKey(850343)ontheplasticHeadGuard(G30145)isin
complete contact with the Safety Interlock Switch (850308) on the Left Guard (G30143).
problem:Stitch quality is poor.
solution:
1. Refer to the Stitcher Head Operator’s Manuals for more information.
2. Make sure that the wire is feeding straight from the Wire Spool and through the Stitcher Head.
3. Make sure the compression setting is correct.
4. Make sure the Clincher Plates are lined up with the Stitcher Head’s Drivers, both side to side
and front to back.
5. Make sure the Clincher Points are not set too high or too low.
6. Make sure the left leg of the stitch is same length as the right leg.
problem:Wire is dropped before it can be formed, drawn in inconsistent lengths or is jamming.
solution:
1. Refer to the Stitcher Head Operator’s Manuals for more information.
2. Make sure that the wire is feeding straight from the Wire Spool and through the Stitcher Head.
3. Check for worn parts on both the Stitcher Head and on the M19 itself.
4. Make sure the Clincher Points are clear of debris and paper build-up.
5. Make sure the Clutch is set to stop 1/8” prior to top dead center at the end of a cycle.

Maintenance
Lubrication (Figure 10)
Figure 10 - Lubrication Points
Your M19 Machine has been fully lubricated at the factory, but regular preventative maintenance
will result in superior performance and a longer life of the machine. Machines that are in constant use
should be lubricated weekly where as machines that are only operated periodically should be
lubricated just prior to use. Usually only a drop of oil is required at each lubrication point. Care must
be taken that those parts of the machine that contact work remain free from oil. Refer to the Stitcher
Head Operator’s Manuals for more information on the lubrication needs for the individual Stitcher
Head on the M19 Stitcher.
Lubricate regularly instead of excessively.
Excessive oiling will result in work becoming oil-spotted. After lubricating the machine, wipe off
any excess oil. Use one drop of any standard S.A.E #10 oil in the following lubrication points:
•thelubricationpointsfortheindividualStitcherHeads.(seespecificStitcherHeadManual)

Always disconnect the power supply before
making any adjustments or servicing the stitcher.

The M19 Stitcher Machine is a single-head Stitcher Machine. But the time may come when
a replacement Head may have to be added or removed from the stitcher. The following are guidelines
for mounting and removing both an 18D and a G20 Stitcher Head to or from the M19.
To mount an 18D Stitcher Head on the M19: Slip two (2) Bonnet Binder Stud Pins (G30148),
through two (2) Bonnet Binder Studs (2609) at both the top and bottom of the 18D Head. Position
the Bender and Driving Slides of the 18D approximately where they will align with the Bender Plate
and Driver Plate Adapters on the M19. Insert the Binder Stud, in the bottom of the 18D Head, into the
lower hole of the Face Plate Adapter (G30026) on the M19 Stitcher. Start one (1) Bonnet Stud Nut
(HN1213) on the Binder Stud to steady the bottom of the Head; just tight enough so the Bender Slide
does not slip off the Bender Plate Adapter. The Bender and Driving Slides may have to be adjusted
manually to match up with the Adapters on the M19. Insert the Binder Stud, in the top of the 18D
Head, into the upper hole of the Face Plate Adapter. Before starting the second Bonnet Stud Nut,
make sure the Head’s Face Plate Adjusting Slide aligns with the Driver Plate Adapter on the M19.
A screwdriver used as a lever between the Driving and Adjusting Slides will facilitate the action.
Completely tighten both the Bonnet Stud Nuts with a 3/4” Wrench.
To mount a G20 Stitcher Head on the M19: Slip two (2) Rear Clamp Pins (G20376) through
two (2) Rear Mounting Bolts (G20341) at both the top and bottom of the G20 Head. Position the
Bender Slide and Feed Slide Block of the G20 approximately where they will align with the Bender
Plate and Driver Plate Adapters on the M19. Insert the Binder Stud in the bottom of the G20 Head
into the lower hole of the Face Plate Adapter (G30026) on the M19 Stitcher. Start one (1) Bonnet
Stud Nut (HN1213) on the Rear Mounting Bolt to steady the bottom of the Head; just tight enough
so the Bender Slide does not slip off Bender Plate Adapter. The Bender Slide and Adjustment Block
may have to be adjusted manually to match up with the M19. Insert the Binder Stud, in the top of
the G20 Head, into the upper hole of the Face Plate Adapter. Before starting the second Bonnet Stud
Nut, make sure the Head’s Face Plate Adjustment Block aligns with the Driver Plate Adapter on the
M19. A screwdriver used as a lever between the Driving Slide and Feed Slide Block will facilitate
the action. Completely tighten both the Bonnet Stud Nuts with a 3/4” Wrench. The Clincher Plate
Assemblies can now be aligned with the Stitcher Head, see pages 13-14 for more details.
To remove a Stitcher Head from the M19: While completely supporting the Stitcher Head, loosen
and remove the two (2) Bonnet Stud Nuts until the Stitcher Head is released from the M19. Lift the
Head off the M19 and set aside.
