In case the lifting height of an Ultra Flat Bag S.Tec is not sufficient
then a maximum of 2 bags can be placed over each other. In this
mode, the lifting height is additive for both Ultra Flat Bags S.Tec.
However the lifting power only corresponds to that of the smaller
bag. Basically, the lower bag should always be inflated first.
Sequence: large bag below,
small bag on top!
Never place 3 or more bags over each other!
An Ultra Flat Bag S.Tec under load can be compared to a spring
under tension with respect to its behavour. As soon as the Ultra
Flat Bag S.Tec is suddenly released, e.g. by slipping, load break or
anything similar then there will be spontaneous catapulting out-
wards of the Ultra Flat Bag S.Tec.
Never stand in front of the Ultra Flat Bag S.Tec!
This is an area of danger!

2.5 Safety instructions
Pre-specified personal protective clothing is to be worn during
operation! For example: protective clothing, helmet, protective
gloves, protection for eyes and face, noise protection etc.
The national regulations in connection with lifting bag systems
and their use are to be observed. For example: DIN EN 13731, na-
tional regulations. The Ultra Flat Bags S.Tec are only to be used
with compressed air, under no circumstances are they to be used
with inflammable gases or aggressively acting gases. Vetter Ultra
Flat Bags S.Tec are only to be inflated with original Vetter inflation
fittings because these were subjected to an acceptance test by
the manufacturer. The lifting bag system is to be tested for perfect
condition before and after use (specifications from the manufac-
turer, national regulations).
The lifted load is to be continually supported during the proges-
sive lifting sequence. The stable condition of foundation support
material must always be observed during construction of the
foundation support.
