2 CORRECT USE
2.1 DEVICE TYPE
Electrostatic manual spray gun for manual coating of grounded work pieces
2.2 CORRECT USE
The GM 5000EAC electrostatic hand spray gun is suitable for spraying liquid products, particularly coating products, using the AirCoat method. Coating products containing solvents of explosion class II A may be used.
2.4 SAFETY PARAMETERS
The GM 5000EAC electrostatic manual spray gun is only suitable for spraying liquid products, particularly coating products. J. Wagner AG forbids any other use! The electrostatic manual spray gun may only be operated under the following conditions:
the operating sta have previously been trained on the basis of this operating manual, the safety regulations listed in this operating manual are observed, the operating, maintenance and repair information in this operating manual is
observed, and the statutory requirements and accident prevention regulations standards in the
country of use are observed.

9
OPERATING MANUAL
EDITION 07/2014 ORDER NUMBER DOC 2344500
2.5 PROCESSIBLE PRODUCTS
With the GM 5000EAC gun, paints can be applied which contain solvents of explosion class II A.
The spray gun basic version is suitable for processing sprayed substances with an electrical resistance of > 150 kΩ (according to the WAGNER scale).
Equipped with a special product hose for low-resistance sprayed substances (available as an accessory) you can also successfully process sprayed substances with an electrical resistance > 50 kΩ (according to the WAGNER scale).
The transfer e ciency is always dependant on the composition of the product being used, e.g. pigmentation or resin.
Conversion of Paint Resistance
There are paint resistance measuring devices available on the market that do not directly measure the speci c paint resistance.
Multiplying the result of the measurement with the device-speci c cell constant (K), we obtain the speci c resistance value of the product.
Example:
With Wagner’s paint resistance measuring device the cell constant is K =123. Measured value according to the WAGNER scale Speci c resistance (RS)
Notice
Using sprayed substances with too low an electrical resistance, the application of electrostatics does not show any e ect, i.e. there is no "paint wrap around" on the object to be sprayed.
The suitability of the sprayed product with regard to the charging ability can be read from the indicators showing the actual values for the high-voltage (kV) and for the spray current (μA) the actual values are shown either on the VM 5000 control unit or on the spray gun.
high kV value, low μA value = ok. low kV value, high μA value = excessive conductivity of the paint
-> no wrap-around
In the event of application problems, please contact your local WAGNER o ce and the paint manufacturer.

4.2.4 CLEANING
De-energize the device electrically. Disconnect the pneumatic supply line. Relieve the pressure from the device. Ensure that the  ash point of the cleaning agent is at least 15 K above the ambient
temperature or that cleaning is undertaken at a cleaning station with technical ventilation. To clean, use cloths and brushes moistened with solvent. Abrasive agents or objects
must not be used. Ensure that the spray gun is not damaged in any way while cleaning. Parts of the spray gun must not be sprayed with or immersed into cleaning agent. Preferably, non-combustible cleaning agents should be used. The choice of the appropriate cleaning agent depends on which parts of the spray
gun have to be cleaned and which product has to be removed. When cleaning the
spray gun only use non-polar cleaning agents to prevent conductive residues on the
surface of the spray gun. Should it however, be necessary to use a polar cleaning agent,
all residues of this cleaning agent have to be removed by using a non-conductive and
non-polar cleaning agent, once the cleaning is  nished. Ensure that no electrical component is cleaned with nor even immersed into solvent.
An explosive gas/air mixture forms in closed tanks.
When cleaning devices with solvents, never spray into a closed tank. Only use electrically conductive tanks for cleaning liquids. The tanks must be grounded.

Large application volume Low fogging tendency Good  nish High viscosity paints can easily be applied High endurance of the AC-nozzles Jet width adjustment
In the AirCoat process, the spray product is atomized under a pressure of 3-15 MPa; 30-150 bar; 435-2,176 psi. With the help of an air pressure of 0-0.25 MPa; 0-2.5 bar; 0-36 psi, a soft, spray jet is produced. The spray jet diameter can be adjusted by turning the nozzle nut.
5.4.1 AIRCOAT ROUND JET SPRAY PROCESS
In the AirCoat process, the spray product is atomized under a pressure of 3-15 MPa; 30-150 bar; 435-2,176psi. With the help of the AirCoat air, with a pressure of 0-0.25 MPa; 0-2.5 bar; 0-36 psi, a soft,  at spray jet is produced which largely eliminates the problem of overlapping in the peripheral zones. With shaping air, there is the possibility of reducing the width of the spray jet.
