8 Installation and commissioning
The machine must only be installed and commissioned by qualified personnel!
All relevant safety regulations must be strictly adhered to!
If the machine is delivered without a table, be sure to use a stand and table top
that can hold the weight of the machine with its motor.
It is very important to ensure that the stand of the machine is firm and steady,
also during sewing.

.01
Installation
The site where the machine is installed must be provided with suitable connections for electric current.
It must be ensured that the standing surface of the machine site is firm and horizontal, and
