1. Important preliminary remarks
Only the knowledge and exact observance of these operating instructions guarantees correct and professional operation, produces the greatest possible use and ensures any claims made within
the scope of the Vetter guarantee.
The handling of the Vetter S.Tec Bag is only to be made by trained
persons using the operating instructions of the manufacturer and
the information from the user. The disposal of discarded lifting
bags is to be carried out according to disposal regulations valid
for the region.
The operating instructions given here are to be regarded as part
of the product and are to be kept for the complete life duration of
the product. In case the product should be passed on to a successive user then the operating instructions must also be included.
2. Product description
2.1 Description of the set
a. S.Tec Bag 10 bar
The selection of bag size must correspond to operation requirements. There are 15 sizes available from 1.1 t to 84.6 t.
b. Ination hoses
In order to inate S.Tec Bags from a safe position for the operator,
there are ination hoses available with lengths of 5 m and 10 m.
The hose colours in RED and YELLOW are used exclusively to assist
the operator in recognizing the correct side when controlling the
S.Tec Bag.
c. Air CU (Control Unit) 10 bar deadman
Connect the ination hoses on the output couplings on the rear
side of the controller. Connect the air suppply to the input coupling on the side. Move the switching lever to the front in order
to inate the S.Tec Bag. In doing this, observe the corresponding
manometer and the load.
When the required operating pressure for the lifting power or lift
height is reached, terminate the ination sequence by releasing
the lever. The switching lever automatically returns back to the
zero position (dead-man switching). The integrated safety valve
activates automatically as soon as the maximum operating pressure of 10 bar is exceeded when inating or when there is a sudden increase in bag pressure caused by an unintended loading of
the bag.
The activation tolerance for opening and closing of the
safety valve must only be a maximum of +/- 10%.
Press the switching lever in the opposite direction in order to deate the bag or to lower the load.

Additional information for illuminated control element
Air CU 10 bar Totmann lighting
The lighting of the control element illuminates all couplings,
switch levers and manometers. It is switched on and o with
switch (1) on the side.
The control element is supplied by a 9 V block battery. Since the
entire lifting bag system is designed for a temperature range of
-20 °C to +55 °C, only batteries with this temperature range are
allowed to be used. Based on the current state of the art, only lithium batteries meet this requirement.
To insert the battery, unscrew the battery compartment, replace
the old battery with a new one and screw the battery compartment back together.
Control elements with lighting come under the German Law on
electrical and electronic devices (ElektroG) of 24 March 2005 for
implementation of the EC Directive 2002/96/EC on electrical and
electronic waste – WEEE Directive.

The label attached to the battery compartment cover points
out that the electronic components in this product must not be
handled as domestic waste; they have to be returned to the manufacturer (return freight paid) for recycling.
d. Dual controller 10 bar with dead-man switching,
aluminium
Press the lower button (1) in order to inate the bag. After release,
the press-button returns again to the zero position and interrupts
the ination sequence. Press the upper button (2) in order to deate.
e. Single controller 10 bar with dead-man switching,
aluminium
If only one S.Tec Bag is used for operation then this can be controlled with a single controller.

Inventory check
On acceptance of the S.Tec Bag equipment a check is to be made
to see if the delivery is complete according to the delivery note.
In addition to this a visual check and function test is to be made
according to the operating instructions.

2.3 Vetter safety coupling system
a. Input coupling of the controller
Connect the air supply hose or the connection hose of the pressure regulator to the nipple of the input coupling (1) on the controller pushing the nipple solidly into the coupling until the ratchet
action can be felt. In order to ensure that it is correctly connected:
turn the brass sleeve (2) of the coupling opposite to the safety
pin (3).
b. Ination hoses
To connect the ination hoses to the corresponding controller or
to the S.Tec Bag, press the hoses or bag nipple solidly into the coupling until the ratchet action can be felt. The coupling sleeve must
be seated on the support ring without any gap (1). To release the
connection (only in the pressure-free condition) the nipple must
be solidly pressed against the spring pressure in the coupling. At
the same time the coupling sleeve must be pushed back. The coupling then releases.
c. Ination with an 8 bar ination device
The S.Tec safety coupling system cannot be used for ination with
other ination devices. However, should it be necessary, in exceptional cases, to inate with the Vetter 8 bar system then the
10 bar / 8 bar adapter must be used.
2.4 Product description
Vetter S.Tec Bags are made by hand from high quality raw materials so that after completion, a seamless bag is produced. The
semi-nished product is vulcanized under the inuence of pressure and temperature and by doing this the individual layers bond
to form an elastomer body. After production has been nalized,
each S.Tec Bag is subjected to a plant acceptance test within the
scope of quality assurance.
Material of the S.Tec Bag: CR/Aramide, hot vulcanized
