Page 5/39
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:
9Incorrect use, operation or maintenance of leak sealers.
9Use of the leak sealers with defective safety devices or inati-
on ttings which have been either incorrectly installed or are
non-functional.
9Non-observance of the instructions contained in the opera-
ting instructions with respect to storage, operation and main-
tenance of the leak sealers.
9Insucient monitoring of accessory parts which are subject
to wear.
9Incorrectly carried out maintenance work.
The following also belong to correct application:
9Observance of all information contained in these operating
instructions.
9Compliance 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. DGUV) 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 incre-
ased protection against acid spray.
Observe the pertinent regulations concerning handling with dan-
gerous liquids.
Protection equipment, such as protection clothing, gloves, hel-
met, face and eye protection, breathing protection and inherent
protection, are to be used onsite depending on the degree of
danger and the situation.

Vetter Leak Sealers
Page 6/39
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 ten-
sioned condition. Only ll the leak sealers until the leak is sealed
(max. operating pressure 1.5 bar and 12 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 ma-
ximum permissible operating pressure.
2.3 Warning information
The leak sealers and the accessories are to be inspected for per-
fect condition before and after use. Damaged seals or seals and
accessories which are functionally limited present a source of dan-
ger 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 pres-
sure 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 chan-
ged. 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 control-
ler 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.

Page 7/39
3. Operation of the Leak Sealers
This chapter gives you information about which sources of com-
pressed 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 rat-
chet”.

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 perti-
nent regulations for work protection and
safety, accident prevention regulations
(e.g. DGUV) 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.
9Route both tension belts through the belt bushing slots or
the swivel eyes.
9The bag is stored in the acid protection covering, possibly
with an upholstery plate underneath, and secured with a Vel-
cro fastener. Please note that the valve connection should lie
in the ap!
9The 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.
9Select and put on the personal protective equipment corres-
ponding to the degree of danger.
9Mark the work area.
9Ensure that only authorized persons are in the work area /
area of danger.
9Select the leak sealing bag/leak sealer according to the requi-
rements.
9In doing this observe the resistance chart and material resis-
tance chart.
9Check the leak sealing bag/the leak sealer and the accessories
to be used for completeness and for any forms of damage.
9Damaged leak sealing bags/leak sealers and accessories must
not be used!
9Ination hose and controller must already be connected to
the leak sealing bag/leak sealer.
9Place the tension belts around the tank/container.
9Loosely close the leak position with the sealing bag / leak sea-
ler.
The simplied illustrations show
only one tension belt!

Page 11/39
9Tension the leak sealer with the tension belts.
9Make certain that there is nobody within the area of danger.
9Inate 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 12 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 ma-
ximum 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.
The Vetter Leak Sealing Bags LD 50/30 come in two dierent versi-
ons each having dierent tensioning possibilities available.
Leak sealing bags with
guide slots

4.3 Handling the tension ratchet
Threading the belt
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.
Tensioning the belt
By moving the ratchet lever, ratchet until the required, or maxi-
mum, 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 rat-
chet, 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 un-
coiled and taken out.
The tie-down straps used in the Vetter systems do not have any
specications on the standard manual force (SHF) and standard
tension force (STF) because here they are only being used as strap-
ping lashes and not for lashing down the load (load restraints).

5.2 Safety valve blow-through
If a safety valve blows too early due to foreign body penetration,
open the blowing device (2) by turning counter-clockwise and
blow through.
If the foreign body is not removed by doing this, then the comple-
te upper part of the valve is to be unscrewed
9To do this, place the pipe pliers at the height (1).
9After unscrewing, carefully take out the valve ball and remove
the foreign body from the sealing plate.
9Screw on the upper part of the valve again and check for per-
fect operation.
9Changes to the set pressure must not be made.
9If the seal on the upper part of the valve is removed then per-
fect function can no longer be guaranteed. The safety valve is
then to be sent back to the manufacturer.
9With icing caused by high humidity and low temperatures, it
is possible to use a normal defrosting spray..
5.3 Visual test of the safety valve
Safety valves are sealed.
If the seal on the upper part of the valve is removed then
perfect function can no longer be guaranteed. The safe-
ty valve must be exchanged.
9Seal exists and is undamaged.
Old safety valves had customs seals
New safety valves have seal plates
