High sew ing security and good sew ability are achieved w iththe
follow ing core threads:

–

Tw o-ply polyesterendless polyestercore-spun

–

Tw o-ply polyesterendless cotton core-spun
(e .g.Frikka,K oban,R asant,...)

Ifthese threads are notavailable,the polyesterfibre orcotton threads
listed inthe table can also be sew n.

Often two-plycorethreads are offered by the thread m anufacturers
withthe sam e designation as three-ply polyesterfibre threads
(3cyl.-spun).This causes uncertaintywith regard totwisting and thread
thickness.

W hen in doubt,unravelthe thread and check w hetheritistwisted 2-or

The labelno.120 on the thread reelofa core thread corresponds e.g.
tothe thread size N m 80/2(seetablevalues in brackets).

In case ofm onofilam entthreads you can use needlethreads and hook

For the operation of the pneum atic com ponents the sew ing unit has to
be provided with anhydrous com pressed air.

ATTEN TION!
For a trouble-free function of the pneum atic contro l processes the

com pressed air net has to be ra ted as follow s:
Even in the moment of maximum air consum ption the minimum

operating pressure must not drop below 6 bar.

In case of a too high air pressure decrease:
–

–

Increase the com pressor output.
Increase the diam eter of the com pressed air supply line.

Connecting th e com pressed air maintenance unit
–

C onnect the connecting hose 3 to the com pressed air net.

S e tting th e operating pressure
–

The operating pressure am ounts to 6 bar.
It can be read off at the m anom eter 1.

–

For setting the operating pressure pull up and turn the ro tary
handle 2.

- Turn in clockw ise dire c tion = increase the pressure

- Turn counte r-c lockw ise = reduce the pressure

ATTEN TION !
No oil-bearing com pressed air must be fed fro m the com pressed air

net.
Behind the filter cleaned com pressed air is withdraw n as blow ing air

for cleaning machine parts and for blow ing workpieces out.
Oil particles contained in the blow ing air lead to malfunction and stains
on the workpieces.
