4 Servicing

4.1 General servicing information

IMPORTANT!

– The mattress support must be supported

during service inspections, to prevent
accidental lowering.

– Only personnel who have received the

necessary instructions or training may
perform service and maintenance of the bed.

– After reconditioning the bed, or if bed

according to the check list.

A service contract can be made in the countries, where
