1.2 Normal
Use
The automatic spray gun must be used only for processing sprayable materials, in parti-
cular:
• lacquers and paints
• grease, oil and anti-corrosion agents
• adhesives, grease, oil and anti-corrosion agents
• ceramic glazes
• stains
If you intend to spray materials that are not listed here, please contact WALTHER
Spritz- und Lackiersysteme GmbH, Wuppertal.
The sprayable materials must be sprayed only on workpieces or objects.
The temperature of the material to be sprayed must not exceed 80°C.
The models PILOT WA 600, WA 610 and WA 625 are not a hand-held spray guns and
must therefore be mounted in a suitable bracket.
Proper use of the spray gun also includes the fact that you have read, understood and
observed all information, advice and safety requirements presented in this instruction
manual.
This equipment complies with the explosion protection requirements of Directive 94 / 9 /
EC (ATEX) for the explosion group, equipment category and temperature class indica-
ted on the type plate. When using the equipment, the requirements specified in these
Operating Instructions must be observed at all times.
The technical data indicated on the equipment rating plates and the specifications in the
chapter "Technical Data" must be complied with at all times and must not be exceeded.
An overloading of the equipment must be ruled out.
The equipment may be used in potentially explosive atmospheres only with the authori-
sation of the relevant supervisory authority.
The relevant supervisory authority or the operator of the equipment are respon-
sible for determining the explosion hazard (zone classification).
The operator must check and ensure that all technical data and the marking of the
equipment in accordance with ATEX are compliant with the necessary require-
ments.
The operator must provide corresponding safety measures for all applications in
which the breakdown of the equipment might lead to danger to persons.
If any irregularities are observed while the equipment is in operation, the equip-
ment must be put out of operation immediately and WALTHER Spritz- und

2 Technical
Description
The models PILOT WA 600, WA 610 and WA 625 are operated automatically by
compressed air and is controlled via 3/2-way control valves. Hand-operated, foot-
operated or solenoid-valve-operated valves can be used for this purpose.
First, the atomising air is introduced by a 3/2-way valve.
Then, the 3/2-way control valve required for the control air is actuated.
The compressed air flowing into the cylinder chamber moves the control piston
and opens the material feed.
If the control air is interrupted by the 3/2-way valve, the compressed air in the
cylinder chamber is allowed to escape. The spring pressure of the piston spring
shuts off the material feed to the material nozzle.
After this, the atomising air is switched off by the 3/2-way valve.
Nozzle and needle are made of corrosion-free stainless steel.
3 Safety
• The spray gun must be used only by trained and qualified persons.
• All relevant rules of safety and workers' safety regulations applicable in the coun-
try or area of use must be fully observed.
• Observe the instructions given by the manufacturers of the spraying material and
the cleaning agents with regard to safety and proper use.
• Use the spray gun only in well-ventilated rooms. Fire, naked flames and smoking
are prohibited within the working area.
