lation systems. Thus, several spray guns can be supplied with spraying material

3.2 Generally Applicable Safety Precautions
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, adhesives, cleaning agents, etc.), there is an
increased risk to health as well as an increased risk of explosion and fire.
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
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!
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. 85 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.
