FOR YOUR BINDING NEEDS.
WARNING!
Model M30 Stitchers
Operators and others in the work area should always wear
safety glasses to prevent serious eye injury from
fasteners and flying debris when loading, operating,
or unloading this machine.
Do not operate this stitcher without all guards in place.
The stitcher will not operate without the front guard
closed properly. Do not modify the guards in any way.
Always disconnect the power supply before removing
any guards for servicing.
Never operate the machine with wire feeding through
the head unless there is stock above the clinchers,
otherwise serious damage may result.
Always turn power off when making adjustments. Always
disconnect the power supply before any disassembly work.
The wire sizes that can be used on the M30 as well as recommended uses are listed below. Note that
when size changes, several parts on the Head will have to be changed to accommodate the wire size
change. Instructions for changing these parts are detailed later in this manual. Wire gauges smaller
than the specific size for which the head is set can still be used, but the maximum capacity for the
machine will not be reached. For example, if the Head is set for 19x21-1/2 gauge wire, it will still
function properly with 20x24 gauge wire, but the stitching capacity will drop. Please refer to Figure
6 stitching capacities of different wire gauges.
Two types of Clincher Points are available for the M30. When running round wire, use the
Clincher Points with part number G40955R. For flat wire, use the Clincher Points with part number
G40955F.
When stitching stock over 20# it is possible that high tensile wire will be required, which is available in 21x25, 20x24, 19x21-1/2, and 18x20 flat wire sizes. Note that high tensile wire may cause
increased wear on certain parts. For any stock over 33# or coated, it is recommended that 19x20-1/2
or 18x20 flat wire be used. Refer to Figure 6 for a general overview of suggested wire sizes to use
for specific stitch capacities.

Introduction
The DeLuxe Stitcher M30 Stitcher Machine is a single-head stitcher designed to accommodate both
light and heavy-duty work, stitch both flat and saddle work and can reliably stitch any thickness of
stock from 2 sheets to 1-1/4” (30mm). It even stab stitches up to 2” (50mm) of material. The recommended wire sizes to be used on the M30 are: 20 to 25 gauge round wire and 20x24, 20x 25, 21x25,
19x21-1/2 and 18x20 flat wire.
The M30 is easily adjusted from saddle work to flat work by tilting the 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 available to accommodate larger sizes of work to be stitched. The M30 is the most versatile of all singlehead machines.
Because of the length of the work table, the M30 must be secured to the floor to meet CE stability
requirements. Sound level readings at the normal operator position are approximately 70 dB.

Troubleshooting (Figure 24)
The following is a brief list of problems and solutions which should cover the majority of situations
encountered when stitching with the M30. The quality and quantity of work that can be produced with
the M30 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, be referring to the troubleshooting chart, quickly locate the solution.
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) counterclockwise 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 is the
case, the entire assembly.
4.Make sure the Safety Interlock Key (850343) on the plastic Head Guard (G40135) is in complete
contact with the switch on the right side of the head.
PROBLEM: The stitch quality is poor.
SOLUTION:
1. Make sure the wire is feeding straight from the Wire Spool and through the Stitcher Head.
2. Make sure the compression setting is correct.
3. Make sure the Clincher Plate (G40952A) is lined up with the Driver, both side-to-side and
front-to-back.
4. Make sure the Clincher Points (G40955R or G40955F) are not set too low or too high.
5. Make sure the left leg of the stitch is the same length as the right leg.
6. Check the following Head parts for wear: the Cutters (G40145 & G40600), Driver, Formers,
Supporter (G40653A), and Wire Holder (G20659BA). Reverse or replace worn parts as necessary.
7. Make sure the Clincher Points are clear of debris and paper build-up.
8. Make sure the Clincher Roller Bearing (G40905), located inside the frame, is not worn or broken.
PROBLEM: Wire is dropped before it can be formed, is drawn in inconsistent lengths, or is jamming.
SOLUTION:
1. Make sure the wire is feeding straight from the Wire Spool and through the Stitcher Head.
2. Make sure the Clincher Points are clear of debris and paper build-up.
3. Check the following Head parts for wear: the Cutters (G40145 & G40600), Driver, Formers,
Supporter (G40653A), and Wire Holder (G20659BA). Reverse or replace worn parts as necessary.
4. Verify that the Wire Holder is properly aligned with the grooves in the Formers.
5. Make sure the Tension Spring on the Wire Spool is not set too tightly.
6. Make sure the Feed Gear Friction Plug is exerting enough pressure on the Large Feed Gear . (Between
3 & 4 turns after contact is made).
7. Make sure there is enough tension on the Feed Lever Spring.
20
PROBLEM: Left Leg Short
SOLUTION: Lengthen the left leg by loosening the two screws on the Cutter
Box Adjustment Slide, and moving the Cutter Box to the left.
PROBLEM: Left Leg Long
SOLUTION: Shorten the left leg by loosening the two screws on the Cutter
Box Adjustment Slide, and moving the Cutter Box to the right.
PROBLEM: Corner Buckled
SOLUTION: Check the Driver for a chipped corner and rotate or replace
if necessary.
PROBLEM: Leg(s) Buckled
SOLUTION: Check the Wire Cutters for wear and rotate or replace if needed.
PROBLEM: Crown Buckled
SOLUTION: Check Supporter Spring tension. Check for correct wire size
being used. Check for correct work thickness setting.
PROBLEM: Stitch in Pieces
SOLUTION: Clean the Wire Holder. If problem persists, file the forming
corner of the Wire Holder slightly with a honing stone. Or replace the Wire
Holder.
PROBLEM: Corners of the Crown are Rounded
SOLUTION: Replace the worn Wire Holder.
PROBLEM: Loose Clinch
SOLUTION: 1. Check for correct work thickness setting. Check and reset the
Clincher Points height if necessary. Check Clincher Points and replace if
worn. Check Clincher Slide and replace if worn.
PROBLEM: Legs are Spread or Contracted
SOLUTION: Readjust the Wire Straightener Eccentrics to improve straight-
ness. Check the Wire Cutters for wear and rotate or replace if necessary.
Check the Former grooves and replace if necessary.

Cleaning
In addition to proper lubrication, routine cleaning is important for the maintenance of the M30
Stitcher Machine. The entire head should be torn down and rebuilt every 250,000 to 500,000 cycles.
The following areas should be cleaned once a month:
• Large Feed Gear (G40510A) remove and wash in an oil-dissolving solvent; dry and relubricate
the clutch and bearings. Use Isoflex NBU 15 Bearing Grease
• Anywhere that dust, oil or pieces of wire and paper have built up - for example: around the
Clincher Points and the Wire Straightener Rollers.
• Blow Head and Clinchers off daily with compressed air.

Clutch-Brake Maintenance
!
Always disconnect the power supply before
making any adjustments or servicing the stitcher
UWARNING
This stitcher is equipped with a solenoid actuated, continuous trip, wrap spring clutch-brake unit.
It is a dependable device and seldom needs service. But should a malfunction occur, the following
information is a service and troubleshooting guide for the maintenance of this unit.
Actuator
The actuator is a simple, straight-forward mechanical linkage. When the actuator does not trip, the
following checks should be made. Refer to Figure 40 for more details.
ProblemCause and Remedy
No power to the Coil.Check all wiring and switching in the Clutch actuat-
ing system.
Lack of continuity in the Coil
Windings.
Mechanical binding of the Plunger. The Coil may have shifted or the Plunger end may
Insufficient clearance for the
Actuator over the Stop Collar.
Actuator loaded by the Stop Collar
so hard that the Actuator cannot be
pulled by the Coil.
Figure 40 - Actuator Checklist
Replace the Coil. (850998 - 230 VAC or 850999
- 115 VAC)
have mushroomed due to striking the Backstop.
In the latter the Plunger may be filed to its true
diameter.
Adjust the Linkage as needed.
Braking force is exceeding the limits of the Brake
or the Differential setting of the unit is too close.
(see Figure 30 for instructions)
33
Clutch and Brake Springs
With the brake engaged (full limit of output), the input hub should be free to rotate by hand. With the
clutch engaged, the input and output hubs should rotate together. If the unit does not rotate in either
of these modes, the clearance between the hubs of the unit on the shaft may have been disturbed or
damaged. See Assembly/Disassembly instructions for re-adjusting.
Listed below are additional checks to be made if the clutch does not function correctly. Refer to
Figure 41 for details.
ProblemCause and Remedy
Clutch Brake does not drive but Input
Motor turns.
Clutch Brake jams and stalls the Input
Motor.
Output does not repeat stopping point 1. Not enough inertia to actuate Brake.
1. Drive Spring (850889) may be broken at thecrossover point from an overload caused by a jam. Replace
the Spring and check the Hubs (851321 or 850892)
for damage.
2. The Control Collar (850888) may not snap forward
because of foreign matter restricting movement.Clean
unit.
3. Actuator Assembly does not pull in. (Figure 28)
1. Spring tang broken off Drive Spring not allowingthe Clutch to disengage while the Brake is engaged.
Replace the Drive Spring.
2. Clutch output is bound up. Check the clearance
between the Output Hub and the Brake Hub.
3. Completely out of adjustment caused by losing an
internal Spring tang. Replace Spring.
2. Tang broken off the Brake Spring. Replace the
Spring.
3. Adjustable Collar Locking Screw may be loose
allowing Adjusting Screw to rotate.
Figure 41 - Clutch and Brake Spring Checklist
34
Disassembly (See figure 42)
To disassembly the Clutch-Brake unit (850673 or 850674) it will be necessary to remove the Drive
Pulley (7678) from the stitcher by removing the V-Belt (850730), Retaining Ring (P7863), and
Clutch Anchor Screw (7681). Disconnect the Ground and Solenoid wires, and swing the anchor strap
(FC9656) clear of the Drive Pulley Assembly and slide it off of the Drive Shaft. Remove the three
(3) Screws (UA4812.7) connecting the Drive Pulley to the Clutch-Brake unit.
When disassembling the Clutch-Brake unit, always mark the Spring Tang locations with reference
to which slots they go in if the same Springs are to be used for reassembly. To disassemble the
Clutch-Brake unit, proceed as follows:
Release the Actuator Lever so that the Clutch is engaged and the Brake is released. Remove the
Retaining Ring and the Shim Washer, if any, from the Input Hub (851321) end. Remove the Input
Hub by rotating opposite to the drive direction. Remove the Retaining Ring and the Shim Washer, if
any, from the Mounting Plate end.
Remove the Output Shaft Springs and the Control Collar (850888) Assembly by rotating the Output
Shaft (850891) in the drive direction. (Do not disassemble the brake Hub (850892) from the Mounting Plate. (850890)) Remove the Control Collar from the Output Shaft and the Spring
Assembly by extracting toward the Brake Spring end.
Assembly (See figure 42)
Replace the Clutch (850889), Brake (850889) and Anti-Back (850962) Springs as required. Assemble
the Springs concentric and square to the Output Shaft.(850891) Assemble the Control Collar over the
Output Shaft and Spring Assembly by inserting it from the Brake Spring End (it will be necessary to
extend the Brake Springs using long nose pliers.) Place the Brake Spring Tang in any one (1) of the
nine (9) Control Collar slots at random.
Assemble the Output Shaft, Springs and Control Collar assembly to the Mounting Plate Assembly by
rotating the Output Shaft in the drive direction. Assemble the Retaining Ring (850886) to the Output
Shaft at the Mounting Plate end (the smooth surface facing the Brake Hub.) Check the end play
between the Hub and the Retaining Ring with a feeler gauge. There should be 0.004” to 0.010” end
play. Use a Shim Washer to adjust if necessary.
Rotate the Output Shaft in the drive direction until it reaches a full brake position. With the Clutch
Spring Tang NOT in slot, insert the Input Hub (851321) by rotating opposite to the drive direction.
Select one (1) of ten (10) Control Collar slots for the Clutch Spring Tang that will provide a 0.38” to
0.50” circumferential overtravel of the Control Collar when released.
35
Note: At this point it may be necessary to reselect one (1) of the nine (9) Control Collar slots for the
Brake Spring Tang (release Actuator Lever, remove the Clutch Spring tang from the slot, then move
Control Collar axially toward the Input Hub end and rotate it opposite to the drive direction to pick
up the next slot). Continue to select Control Collar slots until the 0.38" to 0.50" specification is
achieved.
Assemble the Retaining Ring to the Output Shaft at the Input Hub end (the smooth surface facing the Input Hub). Check the end play between the Input Hub and the Retaining Ring with feeler
gauge. There should be 0.002" to 0.003" end play on the Input Hub.
Reassemble the unit to the machine.
Note: After the Clutch is assembled to the machine, the Clutch Plate should be free to float on
bearing - the Anchor Strap is only there to prevent rotation of the plate.

Lubrication
The clutch-brake unit is designed with the bearing parts made from sintered metal that has been
impregnated with oil and normally do not need to be re-lubricated. In cases where there is severe duty ,
the unit may be re-oiled or flushed out with minimal or no disassembly by using a light bearing oil as
used in manufacture (Shell Bearing Infusion Oil #33). If disassembly of the unit for cleaning and
oiling is necessary, follow the detailed disassembly instructions to the point needed, flush and wipe
parts in the oil to be used for re-lubrication. Do not use solvents to clean the parts. To get more
cleaning action for the oil, it may be heated while cleaning the components, but bring the parts back
to ambient temperature submerged in cool oil.
Coil Replacement
Place the spring onto the plunger with the narrow end towards the actuator. Slide the solenoid onto
the actuator and plate assembly. Assemble the solenoid to the plate assembly with the cap screws and
washers. Do not tighten more than finger tight.
Energize the coil and adjust the gap between the actuator and the top of the collar stop to 0.015" to
0.030" by sliding the solenoid assembly. Note: push the collar toward the actuator to allow for
collar movement. Tighten the cap screws.
Control Collar Adjustment (Figure 43)
The stopping position of the head can be
changed if necessary by adjusting the position
of the stop cam on the control collar sleeve.
Turn the machine manually until the driver is
in the desired stopping position, the proceed
as follows:
Work the Retaining Ring (850886) out of
its groove and slide it forward on the Input
Hub (851321). Slide the cam of the Control
Collar Assembly (850888) off of the splines,
rotate to align the collar stop with the actuator
and slide the cam back on the splines. The
actuator pawl will have to be held clear
during this operation. Slide the retaining ring
back into its groove.
Make sure brake is locked up before
proceeding, to insure the proper stop point.
