A Word to the Operator
The greatest danger inherent in our machines:
is that of fingers, hands or loose clothing being drawn into a machine by live, coasting or rotating tools
or assemblies or of being cut by sharp tools or burned by hot elements.
ALWAYS BE CONSCIOUS OF THESE DANGERS!
Safety Equipment on the Machines
All machines are delivered with safety equipment, which shall not be removed or
bypassed during operation.
The correct functioning of safety equipment on machines and systems should be
checked every day and before every new shift starts, after maintenance and repair
work, when starting up for the first time and when restarting (e.g. after prolonged
shutdowns).
If safety equipment has to be dismantled for setting-up, maintenance or repair work, such safety
equipment shall be replaced and checked immediately upon completing the maintenance or repair work.
All protective mechanisms shall be fitted and fully operational whenever the machine is at a standstill or
if it has been shut down for a longer period of time.
Damage
If any changes capable of impairing safety are observed in the machine or its mode of operation, such as
malfunctions, faults or changes in the machine or tools, appropriate steps must be taken immediately, the
machine switched off and a proper lockout tagout procedure followed. The machine should be examined
for obvious damage and defects at least once per shift. Damage found shall be immediately remedied by
a duly authorized person before resuming operation of machine.
The machine should only be operated when in perfect working order and when all protective
mechanisms and safety equipment, such as detachable protective mechanisms, emergency STOP
systems, etc. are in place and operational.
Faults or Errors
The machine must be switched off and all moving or rotating parts allowed to come to a standstill and
secured against accidental restart before starting to remedy any faults or errors.
Signs on the Machine
Safety and danger signs on the machine should be observed and checked at regular intervals to ensure
that they are complete and undamaged. They should be clearly visible and legible at all times.
Clothing, Jewelry, Protective Equipment
Long loose hair, loose-fitting clothes, gloves and jewelry, including rings, should be avoided in order to
avoid injuries due to being caught, drawn in and wound up inside the machine.

Protective eyewear that has been tested by the local authorities should be worn
whenever there is a possibility of loose or flying objects or particles such as when
cleaning the machine with compressed air.
Tools
Always count the number of tools in your possession before starting work on the machine. This will
allow you to check that no tools have been left behind inside the machine. Never leave a tool in the
machine while working.
Oils, Lubricants, Chemicals
Note the applicable safety regulations for the product used.
No Smoking, Fire, Explosion Hazard
Smoking and open flame (e.g. welding work) should be prohibited in the production area due to the risk
of fire and explosions.
Workplace
A clear working area without any obstructions whatsoever is essential for safe operation of the machine.

Important Notices
Reporting and Fighting Fires
Read the instructions posted in the factory with regard to reporting fires and the emergency exits. Make
sure you know exactly where the fire extinguishers and sprinkler systems are located and how they are
operated. Pass on the corresponding information to the firemen when they arrive. Ensure there are
enough signs to avoid fire hazards.
The following fire extinguishers may be used:
- Dry powder extinguishers, ABC fire-extinguishing powder.
- Carbon dioxide fire extinguishers to DIN 14461 for electronic components. Great care must be
exercised when using carbon dioxide fire extinguishers in confined, badly ventilated rooms (see DIN
14406 and 14270).
Isolate the machine from the power supply if a fire breaks out. Do not use water on burning electrical
parts until it is absolutely certain that they have been completely disconnected from the power supply.
Burning oils, lubricants, plastics and coatings on the machine can give off gases and vapors that may be
harmful to your health.
A qualified person should be consulted to repair the damage after a fire.
Electrical Power Supply
Before undertaking any maintenance or repair work on the machine, switch off the
electrical power to the machine at the main source and secure it with a padlock so
that it cannot be switched on again without authorization.
In practice, this may mean that the technician, electrician and operator all attach
their own padlock to the master switch simultaneously so that they can carry out
their work safely. Locking extension plates should be available for multiple locks if
required. The primary purpose for a lockout/tagout procedure is to protect workers
from injury caused by unexpected energizing or start-up of equipment.
Energy sources (electrical/pneumatic/hydraulic, etc.) for the equipment shall be turned off or
disconnected and the switches locked or labeled with a warning tag. It is the responsibility of the
employer to establish control procedures. Follow lockout/tagout procedures before, setup and/or any
service or maintenance work is performed, including lubrication, cleaning or clearance of jams.
Caution: The machine is still not completely de-energized even when the master
switch is off.
- Electricity - The machine is always isolated from the electrical power supply whenever the master
switch has been switched off. However, this does not apply for the power supply in the control cabinet,
nor for equipment that does not draw its power via the master switch.
- Pneumatic / hydraulic energy - Almost all our machines carry compressed air. In addition to switching
off the master switch, the air supply must also be disconnected and the machine checked to ensure it is
depressurized before starting any work on the machine; otherwise the machine may execute
uncontrolled movements.

- Kinetic energy - Note that some motors or spindles, for example, may continue to run or coast run on
after being switched off.
- Potential energy - Individual assemblies may need to be secured if necessary for repair work.
Delivery of the Machine/Packaging
Note any markings on the packaging, such as weights, lifting points and special information. Avoid
temperature fluctuations. Condensation may damage the machine.
Transport Damage
The packaging and machine must immediately be examined for signs of damage in transit. Such damage
must be reported to the shipper/transporter within the applicable time limits. Contact Atlanta Attachment
Company and/or your transport insurer immediately, if signs of damage are visible. Never operate a
damaged machine.
Interim Storage
If the machine has to be stored temporarily, it must be oiled or greased and stored in a dry place where it
is protected from the weather in order to avoid damage. A corrosion-inhibiting coating should be applied
if the machine has to be stored for a longer period of time and additional precautions taken to avoid
corrosion.
Transporting the Machine
Disconnect the machine from all external connections and secure any loose assemblies or parts. Never
step under a suspended load. When transporting the machine or assemblies in a crate, ensure that the
ropes or arms of a forklift truck are positioned as close to the edge of the crate as possible. The center of
gravity is not necessarily in the middle of the crate. Note the accident prevention regulations, safety
instructions and local regulations governing transport of the machine and its assemblies.
Only use suitable transport vehicles, hoisting gear and load suspension devices that are in perfect
working order and of adequate carrying capacity. Transport should only be entrusted to duly qualified
personnel.
Never allow the straps to rest against the machine enclosure and never push or pull sensitive parts of the
machine. Ensure that the load is always properly secured. Before or immediately after loading the
machine, secure it properly and affix corresponding warnings.
All transport guards and lifting devices must be removed before the machine is started up again. Any
parts that are to be removed for transport must be carefully refitted and secured before the machine is
started up again.
Workplace Environment
Our machines are designed for use in enclosed rooms: Permissible ambient temperature approx. 5 - 40
°C (40 - 104 °F). Malfunctions of the control systems and uncontrolled machine movements may occur
at temperatures outside this range.
Protect against climatic influences, such as electrostatic charges, lightning strikes, hail, storm damage,
high humidity, salinity of the air in coastal regions.
From the library of: Diamond Needle Corp

Technical Manual & Parts Lists
7
Protect against influences from the surroundings: no structure-borne vibrations, no grinding dust, or
chemical vapors.
Protect against unauthorized access.
Ensure that the machine and accessories are set up in a stable position.
Ensure easy access for operation and maintenance (Instruction Manual and layout diagram); also verify
that the floor is strong enough to carry the weight of the machine.
Local Regulations
Particular attention must be paid to local and statutory regulations, etc. when installing machines and the
plant (e.g. with regard to the specified escape routes). Note the safety zones in relation to adjacent
machines.
Maintenance
General Safety Instructions
The machine shall be switched off, come to a standstill and be secured so that it cannot be switched on
again inadvertently before starting any maintenance work whatsoever. Use proper lockout/tagout
procedures to secure the machine against inadvertent startup.
Remove any oil, grease, dirt and waste from the machine, particularly from the connections and screws,
when starting the maintenance and/or repair work. Do not use any corrosive-cleaning agents. Use lint-
free rags.
Retighten all screw connections that have to be loosened for the maintenance and repair work. Any
safety mechanisms that have to be dismantled for setting-up, maintenance or repair purposes must be
refitted and checked immediately after completing the work.
Maintenance, Care, Adjustment
The activities and intervals specified in the Instruction Manual for carrying out adjustments,
maintenance and inspections must be observed and parts replaced as specified.
All hydraulic and pneumatic lines should be examined for leaks, loose connections, rubbing and damage
whenever the machine is serviced. Any defects found must be remedied immediately.
Waste, Disassembly, Disposal
Waste products should be cleared from the machine as soon as possible as not to create a fire hazard.
Ensure that fuels and operating lubricants, as well as replacement parts are disposed of in a safe and
ecologically acceptable manner. Note the local regulations on pollution control.
When scrapping (disassembling) the machine and its assemblies, ensure that these materials are disposed
of safely. Either commission a specialist company familiar with the local regulations or note the local
regulations when disposing of these materials yourself. Materials should be sorted properly.

Repair
Replacement Parts
We cannot accept any liability whatsoever for damage due to the use of parts made by other
manufacturers or due to unqualified repair or modification of the machine.
Repair, Electrical
The power supply must be switched off (master switch off) and secured so that it cannot be switched on
again inadvertently before starting any work on live parts.
Those parts of the machine and plant on which inspection, maintenance or repair work is to be carried
out must be isolated from the power supply, if specified. The isolated parts must first be checked to
determine that they are truly de-energized before being grounded and short-circuited. Adjacent live parts
must also be isolated.
The protective measures implemented (e.g. grounding resistance) must be tested before restarting the
machine after all assembly or repair work on electric parts.
Signal generators (limit switches) and other electrical parts on the safety mechanisms must not be
removed or bypassed. Only use original fuses or circuit overloads with the specified current rating. The
machine must be switched off immediately if a fault develops in the electrical power supply.
The electrical equipment of our machines must be checked at regular intervals and any defects found
must be remedied immediately.
If it is necessary to carry out work on live parts, a second person should be on hand to operate the
emergency OFF switch or master switch with voltage release in the event of an emergency. The working
area should be cordoned off and marked by a warning sign. Only use electrically insulated tools.
Ventilation/Hazardous Gases
It is the end users responsibility to ensure adequate ventilation is provided to exhaust any and all
noxious or hazardous gases that may be present in the working environment.
Hydraulic and Pneumatic Systems
Work on hydraulic or pneumatic equipment shall only be carried out by persons with training,
knowledge and experience of hydraulic systems. Pressure lines shall be depressurized before starting

frame. They operate both of the sewing heads at a slower
speed than automatic speed. They are used for maintenance
and for loading the machine.
Folder/Head Adjustment
The folders are mounted on the sewing head slides and
move with the heads. There are two separate head adjustment
cranks located on the right side of the machine. The front one
adjusts the right head. The rear one adjusts the left head. The
right head is adjusted to align the material with the rewinder
disc and should not normally need adjusting unless the folders
are changed to a different hem size. The left head is adjusted
to desired stitch margin between the hems. There is a scale
and pointer located on the back of the right head that indicates
the distance between the two needles as a reference for
adjusting the needle spacing.
The hems consume approximately 1" of material each,
so, for example, for a finished size of 8" you need to start with
a 10" wide roll. The hems can be sewn with or without
binding. Even if binding is not used, the binding material
sensors must be covered to run the machine automatically.
Sewing stitch length is dependent on the speed of the
puller. The head stitch length is adjusted to be consistent with
the puller speed setting. The more stretchy the material the
longer the stitch length, that can be sewn. Refer to the puller
programming instructions (page 20) for adjustment of the
puller speed drive ratio (parameter 272) in the Efka control
box.
Rewinder
The rewinder motor runs whenever the sewing heads are running. The
winding tension is controlled by a pneumatic clutch which has its own regulator
located inside the left side door. There are tension rods located between the
puller and the rewind spindle that can be adjusted to create more or less drag on
the material, allowing more or less tension to be applied as the material is rolled
up. The material coming out of the puller must go under the lower rod and over
the upper rod.
Caution: Too much tension will over-feed the sewing heads and may cause needle breaks.

Front Roll Holder
The front roll holder has a material out sensor mounted behind the disc. This
sensor can be adjusted up or down to set the amount of material left on the rod
when the machine stops. There should be enough material left to make a splice
when the next roll is loaded. Splices can be made by overlapping the material about
an inch or two and stapling together. Run the splice through the machine with the
manual sew pedals at reduced speed.
Troubleshooting
Machine doesn’t continue to run after the start button is pressed for the second time (Power on
LED will not go out).
1. The thread break detectors are threaded wrong or damaged. (See page 15 for thread sensor
instructions).
2. The fabric sensors are not properly aligned (not looking through the slot) or damaged.
Machine will not stop after fabric runs out
1. The fabric sensor is not properly aligned (not looking through the slot) or damaged.
2. Reflective tape on handwheel is worn or is not at least 1 inch long.
Sewing heads will not run
1. Check head on/off switches on control box.
2. Check that all plugs on motor are plugged in securely.
3. Check motor control boxes for error codes.
Heads sewing, but feed rollers not turning
1. Feed motor control box should be turned on (see power light on control box). Check box for
error codes.
2. Check belt going from motor to feed roller.
3. Check pulleys on motor and feed roller (set screws should be tight).
Heads sewing, feed rollers turning, but cloth not being pulled through
1. Check air pressure, should be 30-40 psi. Higher pressures may cause feed rollers to stall.
2. Check that feed roller switch is set for feed roller down.
3. Check that threads on edge of cloth are not wrapped around roll rod.
