8 Set-up and Initial Commissioning
The machine may only be set up and commissioned by qualified personnel!
All of the relevant safety regulations must always be complied with in this
process!
If the machine was delivered without a table, then the stand and the table top
provided must safely support the weight of the machine and its motor.
Adequate stability of the stand must be guaranteed, even during the sewing
operations.

Suitable electrical supply connections must be provided at the erection site, see Chapter 3
Technical data. The erection site must also have a firm and level subsurface and adequate
lighting.
The table top is lowered for packaging purposes.
The adjustment of the table height is described below.
8.01.01 Setting the table height
Fig. 8 - 01
●Loosen the screws 1and 2.
●Move the table top to the desired working height by pulling it out and pushing it in and
align the table top horizontally.
Adjust the stand on both sides evenly to prevent it tilting.
●The stand must have all four feet firmly on the ground to make sure it is positioned
securely.
●Firmly tighten the screws 1.
●Adjust and tighten the desired pedal position on the screws 2.
