3.4 Mattress base frame
3.5 Chassis
WARNING
Proceed as follows to assemble the mattress base frame on the chassis:
1. Remove the safety side bars and the patient lifting pole from the storage aid and set
them aside for the time being.
2. Remove the two halves of the mattress base frame from the storage aid.
3. Place the head end half of the mattress base frame perpendicular to the floor. The two
patient lifting poles point downwards, while the 2 drive motors point upwards.
4. Now loosen the 4 knurled-thumb screws in the foot end half of the mattress base
frame. Do not completely unscrew the knurled-thumb screws, leave them about 2 turns
in the thread.
5. Now take the foot end half of the mattress base frame and lift it over the head end half
of the mattress base frame. Then fit the two halves of the mattress base frame togeth-
er.
6. Tighten the 4 knurled-thumb screws by hand only (do not use pliers!).
7. Connect the lifting bar of the drive motor to the holders on the mattress base frame at
the foot end. To do so, insert the locking pins through the holder and the lifting bar and
secure the pin by folding the locking lever back over.
8. Now lay the assembled mattress base frame flat on the floor.
Danger due to Trendelenburg position
Failure to comply could result in serious injury to the person lying in bed.
The two chassis should not be confused! A mix-up will lead to an unwanted Trendelenburg
position instead of a reverse-Trendelenburg position.
•
Take care not to confuse the two chassis when assembling the bed.
•
Observe the different labels for identification of the two chassis. These are located cen-
trally on the cross tubes, near the holder for the drive motor, and centrally on the cross
tubes of the mattress base frame.
