Introduction
The HM820 is a development of Habraken-Machines for stitching a wide range of decorative seams.
It is based either on an M-type DA-867 twin-needle, flat-bed, triple transport or an M-type Da-868, twinneedle, post-bed triple transport sewing head.
• Revolutionary concept
The HM820 is based on a revolutionary “rotating needlebar” concept develop by Habraken-Machines.
Because of this concept, high-speed and precise needlebar rotation is achieved.
State-of-the-art technology
•
Utilising state-of-the-art technology, the HM820 is offering a wide range of decorative stitch patterns.
Intuitive technology
•
Combining all benefits of the DA-867 M-type flat-bed triple transport machine with the latest user-friendly
technology, the HM820 is offering a low learning curve.

Description
The HM820 is based on either a DA867 flat-bed or DA-868 sewing head.
The sewing head is driven by an EFKA DA321 control unit in combination with an EFKA DC1550 motor.
By design, operation and functionality of the EFKA DA321 is respected as much as possible. This resulting
in a “standard machine” in case the rotating needle bar is switches off.
Control of the rotating needle bar, selection of decorative seams, options and safety in relation to this
decorative stitching is done by the so called Decorative Stitching Control Unit. This unit consist of a Nais
FP0-R plc in combination with a touch screen.

Safety
Operation of the machine is restricted to authorized personnel only.
Operators and maintenance staff have to be familiar with Dürkopp Adler 867 or 868 sewing

DA321 are integral part of the documentation of the HM820.
Read this and related manuals careful and keep it for future reference!
Detailed information on the DA 867 and Da 868 can be found in the operation instructions
and service manual.
General information on the Efka DA321G5321 can be found in the DA321 instruction manual
and parameter list.
Habraken Machines recommend to wear eye protection when operating the machine.
Habraken Machines recommend to wear ear protection when operating the machine.
Caution Risk of Injury !
When repairing, converting or doing maintenance work turn off the main switch and
disconnect the machine from the pneumatic supply.
Adjustments and function testing on the running machine are to be conducted only by strictest
adherence to all safety measures and extreme caution.

4.4.1 Reference position
The reference position is used to determine all relevant positions related to needle bar rotation and
transport.
After power up, two stitches are needed for the control to determine the exact position. In case the machine
hasn’t been in operation for at least two stitches after power up, the text “not set” is displayed. The
reference position will set automatically within 2 stitches.
Only in rare cases ( e.g.: new plc soft- or hardware) the reference position has to be set.
If you are not sure about the correct setting of the reference position, follow the steps indicated in & 4.5.1.1
Checking the reference position
4.4.1.1 Checking the reference position
