The spray jet is under pressure and can cause dangerous injuries. Avoid injection of
lacquer or ushing agents:
Never point the spray gun at people.
Never reach into the spray jet.
Before any work on the device, in the event of work interruptions and malfunctions:
– Switch o the energy/compressed air supply.
– Relieve the pressure from the spray gun and device.
– Secure the spray gun against actuation.
– Disconnect the control unit from the mains.
– In the event of functional faults: remedy the fault as described in the
"Troubleshooting" chapter.
If necessary or at least every 12 months, the liquid ejection devices must be checked
for safe working conditions by an expert (e.g. WAGNER Service Technician) in
accordance with the guidelines for liquid ejection devices (DGUV [German Statutory

ORDER NUMBER DOC 2312956
GA 4000ACIC
In the event of skin injuries caused by lacquer or ushing agents:
Note the lacquer or ushing agent that you have been using.
Consult a doctor immediately.
4.2.3 GROUNDING THE UNIT
Hazard due to electrostatic charge!
Explosion hazard and damage to the device.
Friction, owing liquids and air or electrostatic coating processes create charges. Flames
or sparks can form during discharge.
Correct grounding of the entire spraying system prevents electrostatic charges.
Ensure that all devices and tanks are grounded before each spraying process.
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g., that they are
wearing static dissipative shoes.
The spray substance supply (spray substance tank, pump, etc.) must be grounded.

VERSION 05/2018
4.2.4 PRODUCT HOSES
Hazard due to bursting of product hose!
The product hose is under pressure and may cause dangerous injuries.
Ensure that the hose material is chemically resistant to the sprayed products and
the ushing agents used.
Ensure that the product hose and the ttings are suitable for the pressure
generated.
Ensure that the following information can be seen on the high-pressure hose:
– manufacturer,
– permissible operating pressure,
– date of manufacture.
Make sure that the hoses are laid only in suitable places. Hoses should not be laid in
the following places under any circumstances:
– in high-traffic areas,
– on sharp edges,
– on moving parts or
– on hot surfaces.
Ensure that the hoses are never run over by vehicles (e.g., fork lift trucks), or that the
hoses are never put under pressure from the outside in any other way.
Ensure that the hoses are never kinked. Observe maximum bending radii.
Ensure that no work is ever performed with a damaged hose.
Make sure that the hoses are never used to pull or move the equipment.
The electrical resistance of the product hose, measured at both valves, must be less
than 1 M .
Suction hoses may not be subjected to pressure.

4.2.5 CLEANING AND FLUSHING
Hazard due to cleaning and ushing!
Explosion hazard and damage to the device.
Preference should be given to non-ignitable cleaning and ushing agents.
When carrying out cleaning work with ammable cleaning agents, make sure
that all equipment and resources (e.g., collection tank, funnel, transport cart) are
conductive or static dissipative and grounded.
Observe the specications of the lacquer manufacturer.
Ensure that the ash point of the cleaning agent is at least 15 K above the ambient
temperature or that cleaning is undertaken at a cleaning station with technical
ventilation.
Explosive gases are produced when aluminum comes into contact with
halogenated hydrocarbons. To clean aluminum, do not use liquids containing
halogenated hydrocarbons.
Take measures for workplace safety (see Chapter 4.1.2).
When commissioning or emptying the device, please note that:
– depending upon the coating product used,
– depending on the flushing agent (solvent) used.
an explosive mixture may temporarily exist inside the lines and components of
equipment.
Only electrically conductive tanks may be used for cleaning and ushing agents.
The tanks must be grounded.
An explosive gas/air mixture forms in closed tanks.
Never spray into a closed tank when using solvents for ushing.

GA 4000ACIC
External Cleaning
When cleaning the exterior of the device or its parts, also observe the following:
Relieve the pressure from the device.
De-energize the device electrically.
Disconnect the pneumatic supply line.
Use only moistened cloths and brushes. Never use abrasive agents or hard objects
and never spray cleaning agents with a gun. Cleaning the device must not damage
it in any way.
Ensure that no electrical component is cleaned with or even immersed in solvent.

The device consists of a gun head (A), gun body (B), drive (C) and base plate (D). The air cap
(G), appropriate nozzle (H) and various parts for sealing and fastening are attached to the
gun head (A). The product valve and packing are housed in the gun head (A). The clamping
mechanism for the packing is installed in the gun body (B). The gun body also serves as
a connecting piece between the drive (C) and the gun head (A). The drive (C) consists a
diaphragm and a pressure spring for the product valve. The base plate (D) contains all
connections (E, J, K) and a shaping air throttle (M). It can be used to connect the gun to the
corresponding reciprocator or gun holder.

GA 4000ACIC
Diagram:
SA = Shaping air
AA = Atomizing air
CA = Control air
M = Product
C = Circulation
Open:
The piston in the drive is charged with control air and moves toward the rear. This ensures
that the air valve which releases the shaping and atomizing air is opened rst. The product
valve is then opened with a mechanical delay. In this position, the pressurized coating
product is applied to the work piece.
Close:
The piston is relieved, and the product valve closes due to the pressure spring which
presses against the product valve tappet. The air valve is then closed, again with a spring
force and mechanical delay.

Additional functions:
The shaping air throttle is used to regulate the shaping air volume, while the atomizing air
is adjusted via an external pressure regulator. The two air streams do not ow separately
until they are downstream of the air valve, so that the pressure of the shaping air
corresponds roughly to that of the atomizing air and so that they inuence each other
during adjustment.
The product connections and the paint channels in the base plate are arranged so that
several guns can run in circulation mode.

In this mode of operation, the left or the right
product channel in the gun head (A) is locked by
the lock pin (M) and the product entrance (ME) is
always on the opposite side.
5.2.2.2 MODE "C" WITH PRODUCT CIRCULATION
In this mode of operation, the lock pin (M)
must be removed from the left or right product
channel in the gun head (A). Screw on additional
connection tting (J). The product entrance (ME)
