5 Spray gun Mignon 3 ENGLISH 1 Function and identification 1.1 Function The spray gun Mignon 3 is used for the coating of surfaces with liquid to low-viscose coating materials. Typical coating materials are: Paints, dyes, adhesives, glazes, enamels, debonding agents, etc. The coating material is fed to the spray gun either under pressure (pumps or pressurised containers to process large quantities of coating material) or through attached gravity feed cups or suction cups (for smaller quantities). Begin spraying process by pulling the trigger. The spraying process is terminated by releasing the trigger. The coating material is atomised using compressed air. The geometry of the spray jet and the sprayed quantity of the coating material can be adjusted: Selection of various air and fluid nozzles Changing of the atomisation air pressure Changing of the coating material pressure Adjustment of the needle stroke on the regulator of the spray gun Adjustment of the flat jet regulator on the spray gun The spray gun Mignon 3 is available in different designs: Supply of coating material: via attached gravity feed cups or suction cups holding from 65 to 300 ml via hose lines on the gun handle via hose lines on the head section The spray gun consists of the following materials: Aluminium (head section), stainless steel (needle and nozzle) as well as brass and plastic (seals). Gravity feed cups and suction cups are made of aluminium, copper or plastic. Check the compatibility of the device materials with the coating materials that are used! 1.2 Identification Type Design Max. atomiser air pressure Max. fluid pressure Product number Mignon 3 Flow design 0.6 MPa / 6 bar 0.4 MPa / 4 bar Mignon 3 Fluid connection on the handle 0.6 MPa / 6 bar 0.4 MPa / 4 bar , , , GB 5

This combination of symbol and signal word indicates potential hazards for the environment , , , GB 7

8 Operating instructions T-Dok-198-GB-Rev Safety information in operating instructions Safety information can refer to specific individual operating instructions. Such safety information is embedded in the operating instructions so that they don't disrupt the reading flow during the execution of the action. The signal words described above are used. Example: 1. Loosen screw. 2. CAUTION! Pinching hazard at the cover! Carefully close cover. 3. Tighten screw. 2.3 Personnel requirements WARNING! Risk of injury in case of insufficient qualification of the personnel! The owner of the system/device is responsible for adhering to the qualifications. If unqualified personnel carries out work on the device or steps into the danger zone of the device, hazards arise which may cause severe injuries and significant material damage. All work must only be carried out by respectively qualified personnel. Unqualified personnel must be kept away from the hazard areas. This manual identifies the qualifications of the personnel for the different scopes of work as listed below: Operator The operator has been instructed by the system owner in an orientation session on the assigned tasks and possible dangers in case of improper behaviour. Tasks that go beyond the operation in standard mode must only be carried out by the operator if such is indicated in this manual and the operate has explicitly been tasked to do so. Qualified personnel Due to their specialised professional training, knowledge, and experience as well as knowledge of the industry-specific standards and regulations, qualified personnel are in a position to perform assigned tasks and to identify and avert potential risks on their own. Only persons who can be expected to perform their tasks reliably are permitted as personnel. Persons whose reaction capability is impaired, e.g. through drugs, alcohol or medication are not permitted. GB 8 mail@krautzberger.com,
