General notes on maintenance
"
Observe the safety-at-work regulations!
"
Disassembly of the elevator machine is not permissible.
"
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.
To check the brake wear the following instructions have to be referred:
It is not possible to adjust the brakes. The brakes cannot be readjusted. Replace the both brake rotors
when the maximum air gap has been reached.
The wear to the brake is checked with the brake closed, therefore:
"
Make sure that all moving parts have stopped, secure them mechanically if required!
"
Make sure that the elevator can not be moved from any other person than the one who does the
check!

using the prescribed tightening torque, the old locking varnish needs to be removed and marking has
to be made again.
