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
Measures must be taken to ensure that the spray gun is sufficiently grounded
(earthed) by means of a conductive air hose (maximum resistance 10
6
Ω
).

Technical Description
Models PILOT IV and IV GM
When actuating the trigger (Item 24) the air valve (Item 18) is opened (preliminary
air); slightly hereafter the material needle (Item 9) is retracted. Closing is in reverse
order.
The material flow rate depends an the diameter of the nozzle.
In addition, the material flow rate can be adjusted by screwing in or out the adjusting
screw (Item 14).
Through the regulating screw (Item 21) the spraying pattern can be controlled, i. e.
left-hand turn = wide jet, right-hand turn = round jet.
Design versions:
Model versions PILOT IV/ IV GM are to be used with gravity-feed cup only.

General Safety Instructions
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 flam-
mable materials (e.g. lacquers, 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
6
Ω
).
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 represent
a serious health hazard!
