NOTE! Do not operate the motors for more than one minute at a time (max. 1 min). Continuous

repetition of movements may overload and damage the motor.

Before moving the bed, the mattress base must be adjusted to its middle position (check visually).

When pushing the bed over a threshold or similar obstacle, always go with the head or foot of the bed first to

reduce the impact on castors or other mechanical parts.

Keep the mattress base of unattended beds in the lower position. (IEC 60601-2-38)

WARNING! When adjusting the bed, ensure that the patient’s fingers, hands or other parts of the body do

not get caught between the bed and accessories or the bed’s moving parts.
