4.2.1.2 Five yearly test
Pneumatic lifters (without compressed air bottle) are to be in-
spected if there is any doubt about safety or reliability but at
least every 5 years according to Section 4.2.3 by a specialist (see
preliminary remarks) having additional training or by an autho-
rized trainer or the manufacturer himself

4.2 Function test of the inflation device
4.2.1 Required test equipment
9 Test manometer 8 bar
4.2.2 Preparations for testing
Connect the air source, e.g. pressure regulator 200/300 bar, to the
input coupling of the controller. Adjust the output pressure on the
regulator to approximately 10 bar.
Connect inflation hose to the output of the controller and con-
nect the manometer 8 bar to the open end.
4.2.3 Operation
Open the shutoff valve on the pressure regulator. Carefully open
the piston valve or ball valve. Monitor and compare the pressure
increase on the manometer of the controller and the test mano-
meter. Increase the pressure until the safety valve activates (per-
missible tolerance according to GUV-G 9102, +/- 10 %). Close the
piston valve or ball valve and check to see if the safety valve per-
fectly closes.
4.2.4 Pressure test of the mini lifting bags 8 bar
Safety instructions
The pressure test must only be carried out after a function test has
been made without establishing any defects. Due to the fact that
with this test the bag could burst, a distance to persons, buildings
and objects must be maintained. Basically, the test should be car-
ried out in outside open spaces.
