The DeLuxe Stitcher M27 Stitcher Machine is a multi-head stitcher designed to
accommodate both light and heavy-duty work, stitch both flat and saddle and is
recognized for being the highest capacity multiple head stitcher due to its ability to
reliably stitch any thickness of stock from 2 sheets to 3/4” (20mm).
The M27 accommodates both the Traditional Style 18D Head and the Side-Feed Style
G20 Stitcher Head. Up to four heads can be mounted along the machine’s 17” (43cm)
rail at a maximum distance of 13” (33cm) between Heads. Because either Head can
be used the recommended wire sizes for the M27 are: 20 to 28 gauge round wire
and 19x21-1/2, 20x24 and 21x25 flat wire. The M27 comes standard with two (2)
Stitcher Heads but replacement Heads can be added when an application requires it.
When ordering extra Heads, add the wire and crown size to the Head part number. For
example: G20MHD20241/2.

G20MHD ....................................................... M27G20AST and M27G20 BST
The M27 is easily adjusted from saddle work to flat work by tilting the 12” (30cm) x
33” (84cm) 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 staples. In addition a work table extension is provided to
accommodate larger sizes of work to be stitched.
The M27 is foot-switch operated and belt driven by a 3/4 HP motor, making possible
operating speeds up to 150 stitches per minute. The motor is mounted on an adjust-
able 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 M27 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 M27 weighs 470 lbs. (213 kgs) net with two (2) Heads and the shipping weight is
approximately 570 lbs. (259 kgs). With the table installed, the M27 requires about 32”
(81cm) x 35” (89cm) of floor space.
Because of the length of the work table, the M27 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 M27 Stitcher. You will need a flat screwdriver and a
9/16 open end wrench. Remove the packing materials from around the M27 and all contents from the
shipping boxes. Mount the Spool Bar Brackets (17282), which are already assembled with the Spool
Bar (17280) and the Wire Guide Spring Bracket Bar (17289), to the Stitcher with four (4) Screws
5/16-18x3/4 (P3318). 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 so
that it is lined up with the stitcher head already mounted to the Machine. Replace the Washers and Hex
Nut. Loosen the Thumb Screw (P2731) in the Set Collar (7691) to remove it and the Tension Spring
Assembly (Figure 1)

The plastic Belt Guard (7676) must be
removed before the M27 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).

(7690) from the Spool Stud. Slide the Wire Spool over the Spool Stud, making 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 stitch-
ing. 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 in position. A properly set Tension Spring will cause the Wire Guide Spring
(15150A or 18150A) to flex but not actually hit the wire spool. The Tension Spring is designed to prevent
the Wire Spool from over-running and tangling the wire.
Remove the assemblies from the complete Work Table Assembly (17145FA): the Right-Hand Side
Paper Guide (A1178), the Left-Hand Side Paper Guide (A1185), four (4) Work Guide Screws (63), the
Back Gauge Bar Assembly (17161A), the Back Stop Gauge (G30164A) and the Plate (17149). Center
the Table Assembly over the Clincher Rail of the machine and secure the Table with the two (2) Pins
(16148). Once the Table is secured, insert the Pivot Rod (17146) through the Table and Clincher Rail.
You may have to use a soft hammer to completely insert the Rod.
Note: Be sure to loosen the two (2) Set Screws (38) before attempting to insert the Pivot Rod.

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.
To tighten the V-Belt (850730C)
first loosen, but do not remove, the
four (4) Hex Nuts (HN3816) on the
Motor Mounting Plate (G30048).
Use a screw driver as a lever
between the stitcher’s frame and the
Mounting Plate to move the Plate down slightly. Pressing on the Pulley (850732) may knock it out of
position. Tighten the four (4) Hex Nuts again when the V-Belt is taut. 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.

The quality and quantity of work that can be stitched on the M27 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 M27 Stitcher are included
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 Lock
(G30158) 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). The thickness gauge is locat-
ed 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 firm-
ly clamped between the Adjuster Spool
and the lower Adjuster Stop. Turn the
Hand Wheel back clockwise 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.
MEASURE HERE
The wire sizes that can be used on the M27 as well as recommended uses are listed below. Refer to the
Operator’s Manual for the Stitcher Heads on your M27 when changing the existing wire size. 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 1/2”. Refer to Figure 5.
Two types of Clincher Points are provided with the heads on the M27. When running round wire, use
the Clincher Points with part number 7257B. When running flat wire, use theClincher 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.
Recommended Wire Sizes (Figures 5 and 6)
Anytime the thickness of work changes, a sample should be tested in the M27 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.
If the machine is operated on work thicker
than it is set to handle, damage will result.

Adjustments and Settings
If the staples are not clinching properly the Clincher Points (7024B, 7024C or 7257B) will need
to be adjusted within the Clincher Plate (7650A). Make sure the Table Assembly (17145FA) is in a
flat work position. If it is not, remove the Plate (17149), loosen and remove the two (2) Pins (16148)
securing the Table position and tilt the Table back. Return the two (2) Pins to secure the Table in the
flat position. To check this, cycle the machine manually and stop it at the point of clincher activation.
Loosen the Set Screw (UA1428.1) and rotate the Clincher Slide Adjustment Screw (18186), which
raises or lowers the Clincher Slide (18182), and 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 Work Table to its original position. Figure 7 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 center-
ing the Clincher Points.
Loosen the two (2) Screws (UA3310.3 or
9081B) securing the Clincher Plate to the
Retaining Plate in the M27’s Clincher Rail.
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. Move the Clincher Plate
Assembly from side to side, until the Driver is
centered above the Clincher Points. The legs
of the staple should line up with the Clincher
Points.
Although the front-to-back alignment is set at
the factory, it can be adjusted one of two ways.
For large adjustment, loosen the two (2) Screws
(G30159) securing the Clincher Rail (G30132)
to the M27 Frame. Using the same half-formed
stitch for centering the Clincher Points, line the
legs of the staple up with the Clincher Points
from back to front. Tighten the Screws to secure the Clincher Rail in this position. Re-check the
side-to-side adjustment after completing the front-to-back
adjustments and then tighten the two (2) screws securing the Clincher Plate to the Retaining Plate
in the Stitcher’s Clincher Rail. Complete the machine’s cycle and remove the formed staple so as to
not jam the Clincher Points. 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.

Troubleshooting
The following is a brief list of problems and solutions which should cover the majority of situations
encountered when stitching with the M27. The quality and quantity of work that can be produced with
the M27 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 the event of problems of this nature occurring,
the operator can, by referring to the following troubleshooting chart, quickly locate the solutions.
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 tnone 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 complete a cycle at all.
solution:
1. Make sure the Safety Interlock Switch (850308) on the Plastic Guard (G30135) is in complete
contact with the Switch on the Left Guard Mount (G30133).
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 Roller Bearing (G30041B), inside the Frame, is not worn or broken.
6. Make sure the Clincher Points are not set too high or too low.
7. 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 M27 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 9)
Your M27 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 M27 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:
Figure 9 - Lubrication Points
1. Oil rods in this area
2. Oil hole in oil cups
Always disconnect the power supply before
making any adjustments or servicing the stitcher.
WARNING
!
The operator should periodically inspect all moving parts for signs of wear and when required,
replace those worn parts. For a complete list of common stitcher head wear parts, refer to the
Operator’s Manual for the specific Head. Some of these parts are two-sided so that when the cutting
or gripping surfaces show signs of wear, their position can be reversed to provide a new working
surface, which lengthens the life of the part.
Replacing Spare Parts
In time, you may need to replace some parts of the M27 Stitcher Machine. To do this locate
the DeLuxe Stitcher part number in one of the following diagrams and contact your Graphic Arts
Representative to order the replacement by part number, description and quantity.

The M27 Stitcher Machine can accommodate up to four (4) Stitcher Heads. The time may
come when additional Heads 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
M27.
To mount a Stitcher Head on the M27: Slip one (1) Bonnet Clamp Block (G20501 or 9002) into the
Lower Bonnet Rail (G30106) and one (1) into the Upper Bonnet Rail (G30107) of the M27 Stitcher,
approximately where the Head will be mounted. Align the Bonnet Clamp Eccentrics (G20524) or
Handles (18005A) in the Stitcher Head with the Blocks on the Machine, starting with the bottom of
the Stitcher Head. Tighten the Eccentric or Handle on the bottom slightly to hold the Head in posi-
tion.
While continuing to support the top of the Stitcher Head, align the Bender Slide with the Bender
Rail Assembly and tighten the Eccentric or Handle at the bottom of the Head a little more. Next line
the Driving Rail up with the Drive Rail Assembly and the Adjuster Block with the Adjuster Rail on
the Stitcher Machine. At this point, the top of the Head should slip over the Bonnet Clamp Block
in the Upper Bonnet Rail. Start to tighten the Eccentric or Handle at the top of the Head then com-
pletely tighten the Eccentric or Handle at the bottom. Completely tighten the Eccentric or Handle at
the Bottom of the Head and verify that the Head is mounted securely to the M27. The Clincher Plate
Assemblies can now be aligned with the Stitcher Head, see page 13 for more details.
To remove a Stitcher Head from the M27: While completely supporting the Stitcher Head, turn
the Bonnet Clamp Eccentrics or raise the Bonnet Clamp Handles until the Stitcher Head is released
from the M27. Lift the Head off the Bonnet Clamp Blocks then remove the Blocks from the Bonnet
Rails.
