8 Installation and commisioning
The machine must only be installed and comissioned by qualified personnel! All
relevant safety regulations are to be observed!
If the machine is delivered without a table, it must be ensured that the stand
and the table top which you intend to use can hold the weight of the machine.
Adequate stability of the base must be guaranteed - during sewing too.
8.01 Installation
The necessary connections for electricity and compressed air, a level and stable surface and
sufficient lightning must be available at the machine’s location.
Due to reasons of packaging, the table top is lowered during transport.
The following is a description of how to adjust the height of the table top.
8.01.01 Adjusting the table-top height
●Loosen screws 1and 2and adjust the table top to the required height.
●Tighten screws 1.
●Adjust the pedals to the required setting and tighten screw 2.
