¶
On erection and during operation, ensure proper
operation of the safety systems and perform checks
regularly and after any malfunctioning.
¶
Only ever have the lifting platform maintained
and repaired by Beissbarth customer service or
an authorized service agent with appropriate
certification.
¶
Always use genuine replacement parts. The
installation of parts from other manufacturers
renders the type approval and any warranty claims
