presser feed in two steps, a needle feed feeds in the first step only.

total stitch length; in double needle machines it represents 30%.
•
Depending on subclass, the machine is either single needle or
double needle unit with automatic functions such as thread
trimming, automatic backtacking, automatic foot lifting, or without
them.

The class 888 is designated for sewing shoe, leather, and upholstery
sewing. In general, the material sewn 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.
The subclass with material trimming is designated especially for the
shoe lining trimming if the lining has the corresponding strength. The
cutting mechanism allows the lining trimming under the leather
surface layer. It is possible to trim also all sewn layers.
It is possible to sew dry material only which may not be thicker than 7
mm when pressed down with a roller presser. The material may not
contain hard objects, as the machine is not equipped with an eye
guard. This machine may be operated in dry rooms and by a trained
person only who is aware of the risks described in this instruction.
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).
