1.2
Intended use
The GA 9010 Marking and GA 9010 Marking-MB automatic spray guns are designed
to be used exclusively for sprayable media, particularly:
•
Paints and lacquers
•
Greases, oils and corrosion protection agents
•
Adhesives
•
Ceramic glazes
•
Staining
Aggressive materials must not be sprayed. Please contact WALTHER Spritz- und
Lackiersysteme GmbH, Wuppertal if the materials you wish to spray are not listed
here.
The sprayable materials may only be applied to work pieces or objects. The GA 9010
Marking and GA 9010 Marking-MB models are not manual spray guns and must
therefore be mounted on a suitable holder.
The temperature of the spray material must never exceed 80°C.
Intended use also encompasses the reading and understanding of, as well as com-
pliance with, all instructions and information contained in the operating instructions.
The device meets the explosion protection requirements of Directive 2014/34/EU
(ATEX) for the explosion group, device category and temperature class specified on
the type plate.
The specifications in these operating instructions must be strictly complied with when
operating this device. The stipulated inspection and maintenance intervals must be
observed.
The information on the device signs or the details in the section on technical data
must be observed and may not be exceeded. Overloading the device must be ruled
out.
The device may only be used in potentially explosive areas in compliance with the
competent supervising agency.

The competent supervising agency or the operating company is responsible
for determining the explosion hazard (zone assignment).
The operating company must verify and ensure that all technical data and the iden-
tification complies with the required definitions according to ATEX. The operating
company must provide appropriate safety measures for applications where failure of
the device might present a hazard to persons.
If any noticeable issues arise during operation, the device must be shut down imme-
diately and WALTHER Spritz- und Lackiersysteme must be contacted.
Earthing/equipotential bonding
It is necessary to ensure that the spray gun is adequately earthed separately or in
connection with the equipment it is mounted on (maximum resistance 10

Technical description
The GA 9010 Marking and GA 9010 Marking-MB models work fully automatically via
a compressed air control system and are activated by means of a 3/2-way control
valve. Hand, foot or solenoid valves can also be deployed.
When the 3/2-way control valve is triggered, the compressed air required by the
control system enters into the cylinder chamber of the spray gun and opens the
atomiser air channel and finally the material supply.
If the control air through the 3/2-way valve is interrupted, the compressed air in the
cylinder will be released first. The spring pressure of the piston spring subsequently
pushes the material needle back to its original position and closes the material and
atomiser air supply.
