8 Mounting and commissioning the machine
The machine must only be mounted and commissioned by qualified personnel!
All relevant safety regulations are to be observed!
If the machine is delivered without a table, be sure that the frame and the table
top which you intend to use can hold the weight of the machine and the motor.
It must be ensured that the supporting structure is sufficiently sturdy, even
during sewing operations.
8.01 Mounting
The necessary electricity supply must be available at the machine’s location. Also, a stable
and horizontal surface as well as adequate lighting are required at the location.
Depending on the type of table, the method of packaging used may require
that the table top be lowered for 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 1 and 2 and set the desired table-top height
● Tighten screws 1 well.
● Adjust the pedal to the desired position and tighten screw 2.
