The site where the machine is installed must be provided with suitable connections for the
electric current, see Chapter 3 Specifications.
It must also be ensured that the standing surface of the machine site is firm and horizontal,
and that sufficient lighting is provided.
The method of packaging used requires that the table top be lowered for
transport. The following is a description of how to adjust the height of the table
top.

Installation and commissioning
8.03 Commissioning
● Clean the machine thoroughly and afterwards fill it with oil and oil the machine (see
Chapter 10, Care and maintenance).
● Check the machine, particularly its electrical wiring and pneumatic tube connections, for
any damage.
● Have skilled personnel check if the machine can be operated with the available mains
voltage.
Do not operate the machine if there is any discrepancy.
Before commissioning the machine, have specialized personnel check whether
the parameter 799 (machine class) is set at "2" and the parameter 800 (sewing
direction) is set at "1". If necessary, have the adjustment carried out (see
Chapter 8.05 Basic position of the machine drive unit).
The machine may only be connected to an earthed socket!
● Connect the machine to the compressed air supply. When it is connected, the gauge
should show a pressure of approx. 6 bar. If necessary, have this reading correctly set
(see Chapter 10.06, Checking/adjusting the air pressure).
8.04 Switching the machine on/off
● Switch the machine on (see Chapter 7.01, On/off switch).
