GM 2000 EAC - EN 1. INTRODUCTION This operating manual contains information and instruction for the operation, repair and maintenance of the spray gun. This equipment can be dangerous if it is not operated in accordance with this Operating manual! Compliance with these instructions constitutes an integral component of the guarantee agreement. 1.1 Using the manual "Caution" This heading is used wherever non-compliance with operating instructions, working instructions, specified working sequences etc.
GM 2000 EAC - EN 1.2 SAFETY REGULATIONS The safety requirements for electrostatic hand spraying equipement are laid down in the following documents: (Germany) 1) ZH 1/250 Electrostatic enamelling with hand-held spraying equipment 2) ZH 1/406 Guidelines for jet stream equipment (spraying devices) 3) EX-RL/ZH 1/10 Explosion protection guidelines - spraying equipment (Published by C. Heymanns-Verlag, Cologne) (Published by C. Heymanns-Verlag, Cologne) (Published by C.
GM 2000 EAC - EN 1.2.4 Protective breathing masks Although the E-Static AirCoat spraying procedure produces very little mist, it is not completely mist free. There are, in fact, few paint particles to be found in the air. Nevertheless, the operator must use a protective breathing mask, (see respiratory equipment instruction sheet ZH 1/134 and VGB 23 from the professional trade association) during spraying operations. 1.2.
GM 2000 EAC - EN 1.3 PTB Conformity certification 1.
GM 2000 EAC - EN 1.4 Product liability and guarantee Important notes on product liability As a result of an EC regulation being effective as from January 1, 1990, the manufacturer shall only be liable for his product if all parts come from him or are released by him, and if the devices are properly mounted and operated. If the user applies outside accessories and spare parts, the manufacturer's liability can fully or partially be inapplicable.
GM 2000 EAC - EN 1.5 CE Conformity 1.5.1 Short explanation CE = Communauté Européenne: Products identified with the CE mark have been manufactured and checked according to EU guidelines. This means that, in terms of materials used, manufacturing process and operation, they are in accordance with the EU safety and health requirements and therefore the EU regulations and standards. The regulations and standards applying to a particular product can be found in the CE Certificate of Conformity.
GM 2000 EAC - EN 2. DESCRIPTION 2.1 Scope of supply Part No. 0179 018 Quantity 1 or 0179 019 1 Description Electrostatic AirCoat spray gun GM 2000 EAC R, with round jet tip R 15 . Electrostatic Air coat spray gun GM 2000 EAC F, without flat jet tip. The standard equipment includes: 0179 901 Universal spanner 0128 901 Tip spanner 0034 041 Coupler fitting NPS1/4-M16x1.
GM 2000 EAC - EN ● The trigger can be used to activate, one after the other, the various functions of the spray gun. An increase in the tension needed to pull the trigger back will be felt at the position where the material valve opens. ● In order to overcome Faraday cages in corners, the high voltage can be switched off by flipping the HV switch (F) down.
GM 2000 EAC - EN 2.3.2 AirCoat round jet process In the AirCoat process, high pressure of 30 to 150 bar is used to atomize the material. The AirCoat air at 0 to 2.5 bar produces a soft jet, which largely eliminates the problem of overlapping boundaries. The spray jet can be adjusted by turning the nozzle nut. The multi-channel swirl nozzle produces fine paint particles, while at the same time reducing their forwards speed and swirling them to produce a rotating motion.
GM 2000 EAC - EN 2.3.4 Electrostatic effect The spray gun produces an electrostatic field by means of the high voltage electrode. As a result, the particles of paint, which have been atomized by the spray gun, are carried to the earthed object by kinetic and electrostatic energy where they adhere, finely distributed, to the object being sprayed.
GM 2000 EAC - EN 3. PREPARATION BEFORE STARTING WORK Caution The operating instructions and the safety regulations for the additional system components used must be read before starting-up . This spray gun must be used a part of an AirCoat-Electrostatic spraying system. The control units VM 200 EN, VM 2000 EN or EPP 200 EN and other various components are also needed (see Wagner-accesories). The spray gun and paint supply system must be flushed out with a suitable cleaning solvent before being used. 3.
