stability, unusual wobbling of mechanisms, looseness, etc. Perform the
following actions for the listed items:
 motors, lifting and sleeping surface adjustment movements, load testing
 the hand-held controller and its functions
 nurse control panel (optional), test the locking functionality
 rail functionality, locking in top position, space between the rails
 accessories, mounting and operation
 if there are unusual sounds, determine the source of the sound
 e.g. if there is an unusually loud creaking sound when adjusting the back
section, check the bearings and the motor fastening pins and clearance,
lubricate the pins/bearings and replace when necessary
Check the operation, locking and sturdiness of the following:
