Installation and commissioning

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 that will reliably support 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.

8.01 Installation

The site where the machine is installed must be provided with suitable connections for electric current and compressed air. It must be ensured that the standing surface of the machine site is firm and horizontal and that sufficient lighting is available.

For packing and transportation reasons the table top is in the lowered position.

The table height is adjusted as described below.
