Generally Applicable Safety Precautions
• It is important that all applicable accident prevention directives as well as industri-
al safety and health rules and regulations are duly complied with.
• Use this spray gun in well ventilated rooms. Open fires, naked lights and smoking
are prohibited in the working area. Spraying of readily flammable media such as
paints, lacquers, cleaning agents, etc., causes a potential health, explosion and
fire risk.
• Prior to any servicing and repair work: Make sure that the spray gun is in unpres-
surized condition, i.e. all air and material inputs must be shut off - if not, imminent
risk of injury.
• Keep your hands and other extremities away from the front of the spray gun
- imminent risk of injury.
• The holder of the spraying unit must be grounded to prevent electrostatic charging.
• Never point the spray gun at persons or animals - imminent risk of injury.
• It is important that all processing specifications and safety warnings issued by the
manufacturers of spraying and cleaning media are duly complied with. Especially
aggressive and corrosive media can cause personal health problems.
• Wear suitable hearing protections while working with the spray gun. Spray guns
produce sound levels of up to 86 dB (A), which may cause hearing defects.
• Air-borne particles must be kept away from the working area and personnel. Wear
proper respiratory protection masks and protective overalls when working with
spraying media. Air-borne particles represent a health hazard.
• Check that nuts and screws are tightened properly after performing servicing and
repair work.
• Make sure you use original WALTHER Spritz- und Lackiersysteme GmbH replace-
ment parts designed for functional reliability and efficiency.
• Should you have any questions concerning the safe operation of the spray gun,
please contact WALTHER Spritz- und Lackiersysteme GmbH, Wuppertal.
