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 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.
8.01 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
that sufficient lighting is provided for.
For packing and transportation reasons the table top is in the lowered position.
The table height is adjusted as described below.
8.01.01 Adjusting the table height
●Loosen screws 1and 2and set the table height as required.
●Firmly tighten screw 1.
●Set the required pedal position and tighten screw 2.
