8.1 General notes on maintenance
Observe the safety-at-work regulations!
Disassembling the elevator machine can only be done with special devices!
Caution, strong magnetic force!
Never use a high-pressure cleaner (for example steam jet cleaner) for cleaning the elevator
machine!
Take note of abnormal operating noise.
The bearings have a lifetime lubrication. There is no possibility to relubricate. Maintenance is not
necessary for the bearings.
