2. Slide the first rotor segment between two T-sliding blocks, and up to the mechanical stop.
3. Tighten the fixing screws on the left-hand T-sliding block, but leave the fixing screws on
the right-hand sliding block loose.
4. Then slide the second rotor segment between the T-sliding blocks directly to the right of
the first rotor segment, and up to the mechanical stop.

WARNING
Danger of severe crushing injuries
Therefore, when the highly magnetic rotor segments are slid into the T-sliding blocks,
they are first drawn toward the mechanical stop. This movement of the rotor segment is
autonomous, and can be as much as about 1/3 of the length of the rotor segment.
If the rotor segments are not placed correctly under the sliding blocks, the rotor segment
which is to be mounted can suddenly fly onto the neighboring previously mounted rotor
segment, when it is is slid between the T-sliding blocks. This can cause severe injuries
to your fingers.
• Correctly place the rotor segments under the T-sliding blocks.
• When sliding the rotor segments between the T-sliding blocks, ensure that your
fingers cannot get trapped between two rotor segments.
