DANGER
Risks due to strong permanent-magnet field
The functions of implanted systems (such as pacemakers) can be influenced.
Metal objects can be attracted and in the event of impact may damage the permanent
magnet, for example.
▶ Anyone with an implanted system must maintain a safety clearance of 5 metres
from the rotor.
▶ Do not place the rotor in the vicinity of metal objects.
▶ Slide the ball bearing ③ onto the rotor ②.
▶ Place the threaded ring ④ on the rotor ②.
▶ Hold the rotor ② with a fork wrench (7 mm), and screw the threaded ring ④ tight
using the socket wrench (left-hand thread).
▶ Push the rotor ② into the stator ①.
▶ Place the ring ③ on the motor unit ② and push into place.
▶ Use the docking guide to push the motor unit ② into the sleeve ④. Push the
docking guide into the sleeve ④ from behind, thread the motor unit's contacts ②
into the docking guide and push the motor unit ② and the docking guide into the
sleeve ④ from the front.
▶ Screw the threaded ring ① into the sleeve ④ using the socket wrench.
▶ Insert the ball bearing ③ into the bearing housing ②, making sure that the ball
bearing ③ is positioned correctly.
▶ Place the bearing housing ② on the rotor ④ and screw into place on the sleeve
⑤ using an open-ended spanner (16 mm).
▶ Place the felt ring ① on the rotor ②.
