5.1
Maintenance and inspection
The progressive type safety gear USG-25P is basi-
cally maintenance free. The whole installation is
designed so that no large maintenance operations
have to be carried out during damage free opera-
tion of the installation.
Inspection checks must be carried out at regular
intervals (minimum once a year with each service)
to guarantee safe operation.
Alterations, damage or other irregularities should
be reported, and repaired if possible. Frequent
servicing and control checks not only make oper-
ation of the installation safer, but also ensure
long and reliable service life.
It is recommended that control checks and ser-
vicing be carried out before legally prescribed
functional tests (e.g. before local authorities
tests).
The lift installation must be immediately
taken out of use should any damage or ir-
regularities arise which could possibly im-
pair operational safety.
Please contact us at WITTUR if you have
any problems or queries.
Maintenance work should be expertly car-
ried out with utmost care in order to
guarantee safe installation operation.
