2.2 Dangers arising from the equipment
This machine was designed and built in accordance with all safety guidelines.
It corresponds with the present standards of technical regulations and current
rules for accident prevention.
It left the factory in perfect condition and ensures a high level of safety.
However, the following dangers exist if operated incorrectly or used
inappropriately:
to life and limb of operator or third personsorr third persons
for the machine and other property belonging to owner of machine
for the efcient working of the machine
All personnel involved in the starting, operation and maintenance of the
machine must read the following notes carefully and observe them. It is a matter
of their safety! We recommend that the machine operation management have
this conrmed in writing.
Additionally, please pay attention to the following: We recommend adding
a copy of all guidelines and accident prevention regulations into the user‘s
manual.
2.3 Application of the machine
This injection unit is designed according to the requirements found in
German ZTV-Riss guidelines for pneumatically driven, single component, high-
pressure equipment.
It is recommended for use with low-viscosity injection materials made from
epoxy or polyurethane and for processing sealant gels.
This equipment is easy to transport and ideal for use on scaffoldings and in
narrow shafts. The stroke rate of the motor informs the operator how close
the injection work is to completion. When the motor stops, the bore hole being
injected is full. To drive the pump, a portable 220V compressor with an air out-
put of approx. 200/Nltr. should be sufcient.
Other usage is not in line with regulations. Before equipment is used
for other purposes or with other materials, and, therefore, not according to
the regulations, permission should be obtained from the manufacturer, as the
guarantee is otherwise invalid. The observation of technical documentation and
the compliance with specied operational, maintenance and starting guidelines
are manditory in accordance with the valid regulations.
2.4 Machine surroundings
2.4.1 Rebuilds and changes
For safety reasons, it is not allowed to carry out rebuilds or changes without
authorization.
Protective equipment may not be dismounted, changed or neglected.
If using components which are not produced or delivered by , warranty
coverage is negated as well as liability.

Safety
Original-Betriebsanleitung HD1+HD2 6
•HD1-2_BAoDB_en_1407•ski
The machine may only be operated within the prescribed limits and machine
parameters.
2.4.2 Danger caused by attachments and spare parts
If you use original attachments and original spare parts from , the
compatability with our equipment is guaranteed. It is, however, essential that
the safety regulations of the attachments and spare parts are observed. You
can nd these safety regulations in the User’s Handbook located with the spare
parts lists.
If you use attachments and spare parts from another source, cannot
guarantee the safety of the entire system. In this case, our guarantee does not
cover any damage or injury caused by such attachments and spare parts.
2.4.3 Emissions
It is possible for solvent vapours to occur, depending on the materials used.
Therefore, please ensure the workplace is sufciently ventilated in order
to avoid damage to health and property. Always observe the processing
information given by the material manufacturer.
The sound pressure level of the equipment is below 85 db(A).
Nevertheless, appropriate means of noise protection should be made available
to the operating staff.
The operator is responsible for compliance with the rules covering the
prevention of accidents due to „noise“ (VGB 121). Therefore, pay special
attention to the environmental conditions at the site, e. g. noise can be
increased if the machine is installed in or on hollow bodies.
Exact details regarding noise emission are mentioned in the Chapter 9.1
Technical specication.
2.5 Sources of danger
Remember that Injection Pumps work under extreme pressures
and that they can cause life-endangering injuries if used inappropriately.
Pay attention to the following notes:
Material hoses must conform to the prescribed maximum working pressure,
allowing for a suitable safety factor.
Material hoses are never to be „patched“!
Never point the injection lance towards yourself, other people or other living
creatures.
Never hold your nger or hand in front of the injection lance and never reach
into the injection stream.
Never try to seal leaks on joints and high pressure hoses with your hand
or by binding the spot. Should a leak occur, the whole system (injection
lance, hose, pressure lter, pump, etc.) is to be depressurized immediately.
Defective parts are to be replaced.
Shut off the injection lance at every pause in working, regardless how short.

Safety
7Original-Betriebsanleitung HD1+HD2
•HD1-2_BAoDB_en_1407•ski
The entire system is to be depressurized before maintenance and cleaning
work is carried out. The compressed air tap lock must be closed.
Never spray solvents or materials containing solvents into a narrow-necked
can or barrels with bung hole.DANGER OF EXPLOSION!
Always use an open container. When using metal containers, always ensure
that the injection lance maintains contact with the container wall to avoid the
build up of electrostatic charges.
If the material being used clogs or clumps within the pump, residual pressure
may still exist despite depressurization efforts. This must be kept in mind
when carrying out repairs! Special care must be taken when dismantling the
material hoses and injection lance to ensure that no accidents occur due to
escaping residual pressure.
We recommend covering the material hose ttings with a cloth during
unscrewing in order to capture any uid which might escape.
Never remove the sealed safety valve installed by and never adjust
its setting.
Should the safety valve need replacing, please see the machine card for its order
number (chapter 9.4).
Please ensure that new safety valves are set and sealed to the maximum
permitted air inlet pressure for the Injection Pumps (see nameplate/
machine card).
In closed or pressurised systems where aluminium or galvanised parts
come into contact with the solvent, dangerous chemical reactions can occur
if 1.1.1-Trichlorethylene, Methylene Chloride or other solvents containing
halogenated chlorinated hydrocarbons (CFCs) are used. If you wish to work
with the above solvents or with lacquers and paints which contain them,
we recommend you contact either customer services or
directly.
The maximum operating pressures given by us are to be adhered to in
principle for all parts (i.e. pump, hoses, injection gun / lance, safety
valve). By differing allowable operating pressures, the lowest
value is always the maximum allowable operating pressure for the entire
system.
Example:
Pump up to 420 ba
Material hose up to 600 bar
Injection Lance up to 350 bar
The maximum allowable operating pressure for this system would be 350
bar.
Smoking is prohibited in the entire area of operation!
2.6 Operating staff
Authorised Operators

4.1 Set-up and Assembly
Task
You wish to erect the machine at the site and prepare it for operation.
Prerequisite
The material to be worked with is prepared.
All materials to be sprayed should be marked with information on viscosity,
processing temperatures, mixing proportions etc. If this is not the case,
please, acquire this data from the relevant manufacturer.
The material to be sprayed must be slowly but thoroughly stirred before
beginning to work.
When dealing with two-component materials, the potlife life must be
observed. The machine must be ushed and completely cleaned with the
specied cleaning agent within the potlife life as given by the manufacturer.
Please, observe that the hardening time shortens at higher temperatures.
It is recommendable to allow the solvent to circulate for a while. It must be
made certain that no particles of paint remain in either the pump or the lter.
Procedure
1. The machine is to be set up securely on a level and solid surface. All
operating elements must be easily accessible. In order that the necessary
volume of air is guaranteed, the compressor capacity must comply with the
amount of air needed by the machine and the diameter of the air supply
hoses must correspond to the joints.
2. Several components of the machine were dismounted and packed in a
separate carton for shipping (i.e. uid hose, injection lance, air pressure
regulator).
Assemble these components as described in chapter 3.
3. Inspect all turnable parts, nuts, screws and hose connections and pull on
them tightly to ensure that no material could leak out of these ttings which
could lead to injuries.
4. Please, check the permissible maximum air pressure for the material hose
and injection lance. It must be greater than or equal to the maximum
operational pressure for the system, which is shown on the nameplate on
the high pressure pump or on the machine card (chapter 9.4).
5. Compare the maximum operating pressure of the safety valve with the
information on the machine card (chapter 9.4) or the nameplate. This
information must correspond.

Maintenance Plan). We recommend using release agent, order
no.: 0163333.
Result
The machine is now ready for operation.
Continue with the rst cleaning (chapter 4.2).
4.2 Initial cleaning
Task
This machine was factory tested after assembly for perfect functioning with a
test-medium. The entire system should be ushed with cleaning solvent before
spray operation begins so that the material to be sprayed is not affected by the
test-medium.
Prerequisite
You will need:
1 open container with approx. 5 liters of solvent, hereafter called container „A“.
1 empty, open container for the mixture of cleaning material and test-medium,
hereafter called container „B“.
Do not use narrow-necked cans or barrels with bung hole.
Please, check whether the material hoses comply with the maximum working
pressure and the prescribed safety factor. They should not have any leaks,
kinks, signs of wear or bulges. The hose ttings must be securely attached and
also comply with maximum pressure.
Please wear protective clothing at all times, as solvent vapours and splashes of
solvent cannot be avoided completely.
Procedure
1. The air tap lock must be closed.
2. Connect the uid hose to the injection lance.
3. Connect the uid hose (with the injection lance) to the uid output on the

7. Open the air tap lock.
8. Adjust the air regulator to a maximum of 2 bar by slowly turning the control
screw to the right.
9. Hold the injection lance into the open container „B“ and spray for at least
10 secondes against the inside wall. When using a metal container, ensure
that contact is maintained between the injection lance and the container
wall (due to possible electrostatic charging).
We recommend a cleaning period of approx. one minute for a good
cleaning result. In order to avoid the danger of explosion caused by the
heating of cleaning material, it should not be pumped for longer periods
of time (a maximum of 5 minutes).
Result
The machine is now completely ushed. Continue with the pressure check
(found in chapter 4.3)
4.3 Checking pressure
Task
You want to inspect the seal on all system components.
Procedure
1. Close the injection lance.
2. Open the air tap lock and set the maximum allowable inlet pressure by
turning the control screw on the air pressure regulator to the right .
Observe the maximum allowable operational pressure for all accessory
components. By differing allowable operating pressures, the lowest value
is always the maximum allowable operating pressure for the entire system
(see example in chapter 2.5).
If the pressure is increased by approx 10% for a short length of time, the
safety valve must blow off.
3. Now check that all parts of the system are tight (uid hose, injection lance
and connections).
4. Now, adjust back the air inlet pressure by turning the control screw of the
air regulator to the left to approx. 1-2 bar.
