Technical Description
The automatic spray guns PILOT WA 560 2-K is all automatic air-controlled gun
operating in combination with a 3/2-way control valve. Hand, foot or solenoid-actua-
ted valves can be used.
At first the atomizing air and the control air are opened together in both guns.
Actuation of the 3/2-way valve directs control air into the cylinder inside the gun of
componet A and B so as to open - in sequence - the atomizing air ducts and the
material inputs of both guns. Material emerges from the horns of air cap (Item 3;
Component A) as well as from nozzle (Item 37; Component B). Mixing takes place in
the spray jet itself.
Closing of the 3/2-way valve is followed by the control air escaping from the cylinder
inside both guns, upon which the spring-loaded material needle returns to its initial
position, where it shuts the material and atomizing air input off in both guns.
The material flow rate and the spray jet contour (flat / wide / round) are adjusted at
the gun by way of regulating screws.
The spray guns PILOT WA 560 2-K can be connected to material pressure tanks and
pumping systems.
The material inlet duct of PILOT WA 560 2-K can be opened manually so as to per-
mit, for example, cleaning of a clogged material outlet nozzle.

Generally Applicable Safety Precautions
•
It is important that all applicable accident prevention directives as well as industri-
al safety and health rules and regulations are duly complied with.
•
Use this spray gun in well ventilated rooms. Open fires, naked lights and smoking
are prohibited in the working area. Spraying of readily flammable media such as
paints, lacquers, cleaning agents, etc., causes a potential health, explosion and
fire risk.
•
You must ensure that the spray gun is properly earthed (grounded) either separa-
tely or in connection with the equipment with which it is being used (maximum
resistance 10
6
Ω
).
•
Prior to any servicing and repair work: Make sure that the spray gun is in unpres-
surized condition, i.e. all air and material inputs must be shut off
- if not, imminent risk of injury.
•
Keep your hands and other extremities away from the front of the spray gun
- imminent risk of injury.
•
Never point the spray gun at persons or animals - imminent risk of injury.
•
It is important that all processing specifications and safety warnings issued by the
manufacturers of spraying and cleaning media are duly complied with. Especially
aggressive and corrosive media can cause personal health problems.
•
Wear suitable hearing protections while working with the spray gun. Spray guns
produce sound levels of up to 86 dB (A), which may cause hearing defects.
•
Air-borne particles must be kept away from the working area and personnel. Wear
proper respiratory protection masks and protective overalls when working with
spraying media. Air-borne particles represent a health hazard.
•
Check that nuts and screws are tightened properly after performing servicing and
repair work.
•
Make sure you use original WALTHER replacement parts designed for functional
reliability and efficiency.
•
Should you have any questions concerning the safe operation of the spray gun,
please contact WALTHER Spritz- und Lackiersysteme GmbH, D-42327 Wuppertal.
