6 Setting the drive
6.1 Setting the drive ratio
The machine is equipped with a 2-step pulley, by which the drive ratio be-
tween the drive motor and the machine can be changed, and the penetra-
tion force of the needle can be increased.
To change the ratio, the drive belt must be removed and the pulley
changed to the opposite position. The drive belt is then refitted and ten-
sioned.
