Improper Use; Technical Description; Safety Warnings; Safety Warning Symbols - WALTHER PILOT WA 30 Operating Instructions Manual

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 requirements.
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 equipment
must be put out of operation immediately and WALTHER Spritz- und Lackiersysteme
must be consulted.
Grounding / Equipotential Bonding
You must ensure that the spray gun is properly earthed (grounded) either separately
or in connection with the equipment with which it is being used (maximum resistance
10 Ω).

Improper Use

This spray gun shall not be used for purposes other than set forth in the above
Chapter 1.2 "Normal Use". Any other form of use and/or application is prohibited and
considered as improper use in contrast to the original engineering design concept.
The term "improper use" also includes such operations as may be:
• spraying of material onto persons and animals
• spraying of liquid nitrogen, etc.

Technical Description

The WALTHER PILOT WA 30 is a pneumatic-controlled automatic airless spray gun
of extreme mini-sized design. Its maximum operating pressure rates 350 bar.
The WALTHER PILOT WA 30 is also available as dosing valve with a maximum
operating pressure of 100 bar.
The gun body is made of aluminum with hard-coated surfaces inside and out. The
spraying medium is fed to the gun in pressurized condition by a piston or diaphragm
pump and atomized the moment it exits from the Airless spray tip.
The PILOT WA 30 spray gun is controlled across a 3/2-way solenoid valve which,
upon actuation, directs control air into the cylinder inside the gun body so as to open
- in sequence - the material input.
Closing of the 3/2-way valve is followed by the control air escaping
from the cylinder inside the gun body, upon which the spring-loaded
material control needle returns to its initial position, where it shuts
the material input off.
The control air pressure must rate at least 4 bar. This automatic spray gun is basi-
cally designed for operation in circulation systems, with one of the bores sealed with
a screw plug (Item 23) which, once removed, can be replaced with a Size
G 1/4" barrel nipple (Item 3) = the gun is now ready for connection to a circulation
system.
All commercial airless spray tips can be used in this PILOT WA 30 gun.

Generally Applicable Safety Precautions

It is important that any and all applicable national and local accident prevention
directives, industrial safety and health rules and regulations and, especially, the
safety provisions set forth for pressure-jet spraying equipment are duly observed and
met. The gun shall only be operated in properly ventilated spaces.
No open fires and naked lights as well as smoking are allowed in the work area - risk
of fire and explosion, particularly when spraying readily flammable media such as,
for example, paints, lacquers, cleaning solutions, etc.
Prior to any servicing and repair work: Make sure that the spray gun is in unpressu-
rized condition, i.e. all air and material inputs must be shut OFF - risk of injury.
Keep your hands and other extremities away from the front of the pressurized gun
during the spraying process -- risk of injury.
Never point the spray gun at anything living - risk of injury. The maximum operating
pressure rates 350 bar.
Piston or diaphragm pumps must always be operated in combination with a material
flow regulator valve in order to ensure that the allowable maximum operating over-
pressure of 350 bar is never exceeded.
It is important that all processing specifications and safety warnings issued by the
manufacturers of spraying and cleaning media are duly complied with. Remember:
Aggressive and corrosive media represent risks and hazards to personal health, and
may cause material damage.
Air-borne particles represent a health hazard and must therefore be kept away from
the working area, towards which end ventilation systems are used. Extra protection
is still needed and it is therefore important that anybody engaged with spraying
media wears proper respiratory protection masks and protective overalls.
Spray guns produce sound levels of up to about 82 dB (A). It is therefore important
to wear suitable hearing protectors.
