Set-up and Initial Commissioning
8 Set-up and Initial Commissioning
The machine may only be set up and started up 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.
8.01 Set-up
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.
