5.1.3
Cleaning of guide rails
Any dust or dirt on the guide rails can have influ-
ence to the friction between the guide rail and the
safety gear. This means that the guide rails must be
cleaned carefully whenever the dirt becomes visi-
ble on the guide rails or in minimum once per year.
As cleaning fluid a disc brake cleaner or a
similar fluid should be used.
Mechanical cleaning like filing, grinding is
not permitted.
5.2
Returning tests
The standard levels of returning tests should not
be higher than the standards of the tests before
installation.
These returning tests are not allowed to cause
wear or stresses that impair the operation reliabil-
ity of the elevator. The tests must be done with
empty car and reduced speed.
The reset of the safety gear must be done
by an expert person.
Each gripping test has to be documented and a
copy of the test report should remain in the eleva-
tor book.
For detailed adjustment dimensions and testing
procedures refer to chapter 4. Functions testing.
