1.2 Correct handling and usage
Depending on the application, Vetter leak sealers must only be
used with compressed air and only inated to the corresponding
pressure with original ination ttings.
They are exclusively used for sealing leaks on containers and
pipes.
Incorrect application of Vetter leak sealers includes the following:
9 Incorrect use, operation or maintenance of leak sealers.
9 Use of the leak sealers with defective safety devices or inati-
on ttings which have been either incorrectly installed or are
non-functional.
9 Non-observance of the instructions contained in the opera-
ting instructions with respect to storage, operation and maintenance of the leak sealers.

instructions.
9 Compliance to the periods for maintenance and care contai-
ned in the Chapter “Maintenance and Care”.
2. Safety instructions
The use of Vetter Leak Sealers is made under the precondition that
there is a knowledge of this application and that the operating
instructions are observed.
2.1 General information
The observance of all pertinent regulations with respect to work
protection, safety and accident prevention (e.g. GUV) as well as
generally recognized technological regulations is a precondition.
Leak sealers must be tested before application to see whether
they are resistant against hazardous materials. For this, refer to the
resistance chart!
The PVC acid protection cover for the leak sealing bag oers increased protection against acid spray.
Observe the pertinent regulations concerning handling with dangerous liquids.
Protection equipment, such as protection clothing, gloves, helmet, face and eye protection, breathing protection and inherent
protection, are to be used onsite depending on the degree of
danger and the situation.

2.2 Information concerning the dangers
Danger of explosion! If there are inammable liquid or gas leaks it
is imperative that sparks be avoided by xtures and ttings.
Vetter Leak Sealers must only be lled when in the correctly tensioned condition. Only ll the leak sealers until the leak is sealed
(max. operating pressure 1.5 bar and 10 bar). Any additional lling
of the leak sealer can damage the pipe or the tank by built up
pressures
A leak in a tank or container is a weak point. Therefore avoid any
additional damage by lling the leak sealer so that no more liquid
or gas escapes. This can be the case at a point lower than the maximum permissible operating pressure.
2.3 Warning information
The leak sealers and the accessories are to be inspected for perfect condition before and after use. Damaged seals or seals and
accessories which are functionally limited present a source of danger and must not be used!
All controllers are equipped with a safety valve that corresponds
to the maximum permitted operation pressure for leak sealers.
These safety valves will blow when the maximum operating pressure is exceeded.
The tolerance for the opening and closing of the safety valves
must be a maximum of + 10%. The set pressure must not be changed. Should the seal on the upper part of the valve be removed
then safe operation can no longer be guaranteed. The safety valve
must be exchanged. The permitted input pressure at the controller must not be exceeded (marked on the input coupling).
Before application of the leak sealer, cover sharp edges and/or
pointed positions in the area of the leak by using dimensioned
sealing plates. In doing this you avoid damage to the leak sealers
as well as the unintended escape of dangerous liquids and gases.

3. Operation of the Leak Sealers
This chapter gives you information about which sources of compressed air you are able to use with Vetter leak sealers.
When using leak sealers observe the
corresponding pressure stage.
3.1 Operation with controllers, ination hose and
compressed air bottle
As an example the following pictures present
the sequence of events for leak sealing
bags 1.5 bar. Corresponding leak sealers
and accessories must be used for other
pressures and other sources of air.
Before ination, the leak sealing bags
must be correctly and safely tensioned
with tension belts on the leak position.
To do this, refer to Chapter 4.3 “Handling the tension ratchet”.

4. Application of Leak Sealers
This chapter gives you information about how Vetter leak sealers
are used.
When using leak sealers, observe the safety
instructions in Chapter 2 as well as the pertinent regulations for work protection and
safety, accident prevention regulations
(e.g. GUV) and the general rules for technology.
4.1 Use of the acid protection covering
The special design of the acid protection covering permits storing
the ready-for-use leak sealing bag including the tension belts on
the emergency vehicle.
The simplied illustrations show
only one tension belt!
9 Route both tension belts through the belt bushing slots or
the swivel eyes.
9 The bag is stored in the acid protection covering, possibly
with an upholstery plate underneath, and secured with a Velcro fastener. Please note that the valve connection should lie
in the ap!
9 The tension belts are accommodated in the upper Velcro-fas-
tener pocket.
4.2 Preparing for operation
Wear the required protective gear and clothing suitable for the
task.
9 Select and put on the personal protective equipment corres-
ponding to the degree of danger.
9 Mark the work area.
9 Ensure that only authorized persons are in the work area /
area of danger.
9 Select the leak sealing bag/leak sealer according to the requi-
rements.
Page 10/39
9 In doing this observe the resistance chart and material resis-
tance chart.
9 Check the leak sealing bag/the leak sealer and the accessories
to be used for completeness and for any forms of damage.
9 Damaged leak sealing bags/leak sealers and accessories must
not be used!
9 Ination hose and controller must already be connected to
the leak sealing bag/leak sealer.
9 Place the tension belts around the tank/container.
9 Loosely close the leak position with the sealing bag / leak sea-
ler.
9 Tension the leak sealer with the tension belts.
9 Make certain that there is nobody within the area of danger.
9 Inate the leak sealer from a safe position until the leak is
sealed.
Danger of explosion! If there are inammable liquid or gas leaks it
is imperative that sparks be avoided by xtures and ttings.
Vetter sealing must only be lled when in the correctly tensioned
condition. Only ll the leak sealing until the leak is sealed (max.
operating pressure 1.5 bar and 10 bar). Any additional lling of
the leak sealer can damage the pipe or the tank by built up pressures.
A leak in a container or pipe is a weak point. Therefore avoid any
additional damage by lling the leak sealer so that no more liquid
or gas escapes. This can be the case at a point lower than the maximum permissible operating pressure.
Before application of the leak sealer, cover sharp edges and/or
pointed positions in the area of the leak by using dimensioned
sealing plates. In doing this you avoid damage to the leak sealers
as well as unintended escape of dangerous liquids and gases.

4.3 Handling the tension ratchet
Threading the belt
1
With the ratchet closed, quickly pull the locked function slide (1)
in order to move the ratchet lever (2). Thread the end of the belt
into an appropriate position in the slot shaft (3) and pull until the
belt is tensioned.
3
Tensioning the belt
By moving the ratchet lever, ratchet until the required, or maximum, belt tension is obtained. In doing this there must be at least
1.5 turns on the slot shaft.
Closing the ratchet
After this, pull the function slid and swing the ratchet lever into
the locking position until the slid is able to lock into the securing
groove.
Opening the ratchet
Before opening the ratchet it is imperative to ensure that the leak
sealing bag is not under pressure because when opening the ratchet, the belt is suddenly released.
When opening the ratchet, the function slid is to be pulled and
the ratchet lever is to be swung approximately 180° to the end
stop in order to let the slide lock into the last possible position.
The slot shaft is now no longer locked. The belt can now be uncoiled and taken out.
