Foreword

This instruction manual is intended to help the user to become familiar

with the machine and take advantage of its application possibilities in

accordance with the recommendations.

The instruction manual contains important information on how to

operate the machine securely, properly and economically. Observation

of the instructions eliminates danger, reduces costs for repair and

down-times, and increases the reliability and life of the machine.

The instruction manual is intended to complement existing national

accident prevention and environment protection regulations.

The instruction manual must always be available at the machine/sewing

unit.

The instruction manual must be read and applied by any person that is

authorized to work on the machine/sewing unit. This means:

–Operation, including equipping, troubleshooting during the work

cycle, removing of fabric waste,

–Service (maintenance, inspection, repair) and/or

–Transport.

The user also has to assure that only authorized personnel work on the

machine.

The user is obliged to check the machine at least once per shift for

apparent damages and to immediatly report any changes (including the

performance in service), which impair the safety.

The user company must ensure that the machine is only operated in

perfect working order.

Never remove or disable any safety devices.

If safety devices need to be removed for equipping, repairing or

maintaining, the safety devices must be remounted directly after

completion of the maintenance and repair work.

Unauthorized modification of the machine rules out liability of the

manufacturer for damage resulting from this.

Observe all safety and danger recommendations on the machine/unit!

The yellow-and-black striped surfaces designate permanend danger

areas, eg danger of squashing, cutting, shearing or collision.

Besides the recommendations in this instruction manual also observe

the general safety and accident prevention regulations!

General safety instructions

The non-observance of the following safety instructions can cause

bodily injuries or damages to the machine.

1. The machine must only be commissioned in full knowledge of the

instruction book and operated by persons with appropriate training.

2. Before putting into service also read the safety rules and

instructions of the motor supplier.

3. The machine must be used only for the purpose intended. Use of

the machine without the safety devices is not permitted. Observe all

the relevant safety regulations.

4. When gauge parts are exchanged (e.g. needle, presser foot, needle

plate, feed dog and bobbin) when threading, when the workplace is

left, and during service work, the machine must be disconnected

from the mains by switching off the master switch or disconnecting

the mains plug.

5. Daily servicing work must be carried out only by appropriately

trained persons.

6. Repairs, conversion and special maintenance work must only be

carried out by technicians or persons with appropriate training.

7. For service or repair work on pneumatic systems, disconnect the

machine from the compressed air supply system (max. 7-10 bar).

Before disconnecting, reduce the pressure of the maintenance unit.

Exceptions to this are only adjustments and functions checks made

by appropriately trained technicians.

8. Work on the electrical equipment must be carried out only by

electricians or appropriately trained persons.

9. Work on parts and systems under electric current is not permitted,

except as specified in regulations DIN VDE 0105.

10. Conversion or changes to the machine must be authorized by us

and made only in adherence to all safety regulations.

11. For repairs, only replacement parts approved by us must be used.

12. Commissioning of the sewing head is prohibited until such time as

the entire sewing unit is found to comply with EC directives.

13. The line cord should be equipped with a country-specific mains

plug. This work must be carried out by appropriately trained

technicians (see paragraph 8).

It is absolutely necessary to respect the safety

instructions marked by these signs.

Danger of bodily injuries !

Please note also the general safety instructions.

1. Product description

Dürkopp Adler 887 is a special sewing machine for universal use.

•It is a flatbed double-lockstitch machine.

•The machine has a double intermittent feeding. A lower wheel

feeder and a driven roller presser feed in two steps, a needle feed

feeds in the first step only. The first step represents 50% of the total

stitch length.

•Depending on subclass, the machine may be equipped with a large

or oversized hook, with automatic functions such as thread

trimming, automatic backtacking, automatic foot lifting.

•Equipped with a two-piece vertical hook.

•With a maximum of 12 mm clearance when sewing feet are lifted.

•The residual thread length after thread trimming is about 15 mm.

•A safety clutch prevents a changing of the hook setting or a hook

damage in the case of a thread deflection into the shuttle track.

•The throat plate has replaceable inserts with the stitch hole

dimension difference, which are optional in dependence on the

needle number.

•Automatic wick lubricating with an inspection glass on the arm for

machine and hook lubrication.

•Integrated winder.

2. Designated use

The 887 is a sewing machine designated for shoe, leather, and

upholstery sewing. The usual material is leather (natural or artificial).

It is possible to use it for shoe fabrics too. The equipment for light,

medium or heavy sewing is mounted on the machine as an option.

This special sewing machine can also be used to produce so-called

technical seams. In this case, however, the operator must assess the

possible dangers which may arise (with which DÜRKOPP ADLER AG

would be happy to assist), since such applications are on the one hand

relatively unusual and, on the other, so varied that no single set of

criteria can cover them all. The outcome of this assessment may

require appropriate safety measures to be taken.

Generally only dry material may be sewn with this machine. The

material may be no thicker than 7 mm when compressed by the

lowered sewing feet. The material may not contain any hard objects,

since if it does the machine may not be operated without an

eye-protection device. No such device is currently available.

This special sewing machine may be set up and operated only

in dry, well-maintained premises. If the sewing machine is used in

premises which are not dry and well-maintained it may be

necessary to take further precautions (which should be agreed in

advance - see EN 60204-31:1999).

As manufacturers of industrial sewing machines we proceed on the

assumption that personnel who work on our products will have

received training at least sufficient to acquaint them with all normal

operations and with any hazards which these may involve.
