Troubleshooting
Vetter Mini-Lifting Bags
have no moving parts
which can wear or have to
be serviced.
Despite the greatest of care
and quality control meas-
ures faults can occur during
deflation of the bags.
Bag nipple iced over
Ice may form in the bag’s
nipple at temperatures
below zero or in cold, moist
air.
If this occurs use normal
antifreeze spray or warm
the nipple in your hands.
Foreign bodies in bag
nipple
Use a blunt wire to clean
the nipple.
Hoses and controllers
should only be serviced by
authorised dealers or the
manufacturer whenever
necessary.
Recurrent tests
See following pages for
tables.
The operator is responsible
for the correct performance
of the recurrent tests in
accordance with the
Pressure Vessel Legis-
lation. The TÜV authorities
(TÜV Rheinland) are
familiar with the special test
requirements since they
frequently carry out these
tests. The statutory tests by
TÜV safety experts are
performed a number of
times during the year on
the premises of Manfred
Vetter GmbH.
The Mini-Lifting Bags can
be economically tested in
collective tests.
The test pressure for
recurrent pressure tests
using water is 1.3 times the
permissible working
pressure.
