6.1 Setting the drive ratio (Classic)

The machine is equipped with a 2-step pulley, which can be used to adjust
the drive ratio between the drive motor and the machine, and increase
the penetration force of the needle.
In order to change the ratio, the drive belts must be disassembled and
the pulley changed to the opposite position. The drive belt is then refitted
and tensioned.
