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 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 separate-
ly or in connection with the equipment with which it is being used (maximum resi-
stance 10 Ω).

Technical Description

The model PILOT WA 81 is operated automatically by compressed air and is con-
trolled 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 com-
pressed 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 cylin-
der 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.
The spray gun works with the equal pressure method. This means that the atomi-
sing air pressure and the material pressure must be almost the same.
All parts which are in contact with the material are made of corrosion-free stainless
steel.

General Safety Instructions

The spray gun must be used only by trained and qualified persons.
All applicable accident prevention rules and regulations as well as other recognised
industrial safety and health rules and regulations must be observed at all times.
Use the spray gun only in well-ventilated rooms. Fire, naked flames and smoking
are strictly prohibited within the working area. WARNING – during the spraying of
flammable materials (e.g. lacquers, adhesives, cleaning agents, etc.), there is an
increased risk to health as well as an increased risk of explosion and fire.
Measures must be taken to ensure that the spray gun is sufficiently grounded
(earthed) by means of a conductive air hose (maximum resistance 10
Before carrying out maintenance or servicing work, always ensure that the air and
material feed to the spray gun have been de-pressurised. Risk of injury!
When spraying materials, do not place your hands or other parts of the body in front
of the pressurised nozzle or the spray gun. Risk of injury!
Never point the spray gun at persons or animals. Risk of injury!
Always observe the spraying and safety instructions given by the manufacturers of
the spraying material and the cleaning agent. Aggressive and corrosive materials in
particular can be harmful to health.
Exhaust air containing particles (overspray) must be kept away from the working
area and personnel. In spite of these measures, always wear the regulation brea-
thing masks and protective overalls when using the gun. Airborne particles repre-
sent a serious health hazard!
Always wear hearing protection when using the gun or when in the vicinity of a gun
that is in use. The noise level generated by the spray gun is approx. 83 dB (A).
After carrying out assembly or maintenance work, always ensure that all nuts, bolts
and screw connections have been fully tightened before the gun is used.
Use only original replacement parts, since WALTHER can only guarantee safe and
fault-free operation for original parts.
