6.1
Maintenance and inspection
The braking system EBRA20 is basically mainte-
nance free. The whole installation is designed so
that no large maintenance operations have to be
carried out during damage free operation of the
installation.
Inspection checks must be carried out at regular
intervals (minimum twice 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 operation of the installation
safer, but also ensure long and reliable service life.
It is recommended that control checks and servic-
ing be carried out before legally prescribed func-
tional tests (e.g. before TÜV tests).
The lift installation must be immediately
taken out of use should any damage or
irregularities arise which could possibly
impair 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 guar-
antee safe installation operation.
6.1.1
General
The EBRA20 can only be used with sliding
guides shoes. Therefore a thin coating of
the guide rail oil is to be applied to the
guide rails.
The lubrication oil may not include high
pressure additives.
6.1.2
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
braking system. This means that the guide rails
must be cleaned carefully whenever the dirt
becomes visible 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.
