Normal Use

The automatic spray guns of the series PILOT WA 700 are exclusively designed for
use with sprayable material types and grades such as:
• paints and lacquers
• greases, oils and corrosion preventives
• adhesive compounds
• Separating agent
• ceramic glazes
• pickling solutions
Should the materials which you want to spray not be listed above, please contact
WALTHER Spritz- und Lackiersysteme, Wuppertal for further and detailed
information.
Please note that sprayable material may only be applied to work pieces and/or
similar items. The temperature of the spraying materials shall never exceed 80
degrees Celsius. The models of the series PILOT WA 7XX are not designed for
manual operation, and must be installed in a suitable gun mounting device.
The term normal use also implies that any and all safety warnings, operational
handling details, etc., as stated in these operating instructions, must be carefully
read, understood and duly complied with.
This equipment complies with the explosion protection requirements of Directive
2014/34/EU (ATEX) for the explosion group, equipment category and temperature
class indicated 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
authorisation of the relevant supervisory authority.
The relevant supervisory authority or the operator of the equipment are
V 20 700
responsible for determining the explosion hazard (zone classification).
V 20 710
The operator must check and ensure that all technical data and the marking of the
V 20 720
equipment in accordance with ATEX are compliant with the necessary requirements.
V 20 730
V 20 740
The operator must provide corresponding safety measures for all applications in

The models PILOT WA 700 are an all-automatic air-controlled guns operating in
combination with a 3/2-way control valve in the form of hand-, foot- or solenoid
actuated valves.
Actuation of the 3/2-way control valve directs control air into the cylinder inside the
gun so as to open - in sequence - the atomizing air and the material input.
The shape of the spray (flat / wide / round) is set on the gun with the models PILOT
WA 7XX using regulating screws.
If the control air through the 3/2-way valve is interrupted, compressed air remaining
in the cylinder chamber will first escape. The spring pressure of the piston spring
subsequently pushes the material needle to its original position, closes the material
supply and finally the spray air.
The material flow volume is set with all models via the material pressure and by
limiting the orifice travel of the material needle on the cap (Item 26). The material flow
of the automatic spray gun series
PILOT WA 7XX can also be opened by hand using the pulling rod (Item 27) to clean,
for example, a clogged material nozzle.
