Caution
The following points should receive special attention for the safe use of the
electrostatic spraying equipment:
1.2.1 Caution! Danger of injury by injection
The pressure should be released from the spray gun during breaks in
work or while assembling and dismantling the nozzle. It should be
secured, the control unit switched off, and the plug pulled out. Never
point the gun at yourself or any other person, the spray jet can cause
injury by injection.
Never put your finger or hand in the spray jet.
In case of injury to skin by paint or cleaning agents consult a doctor
immediately. Inform the doctor of the type of paint or cleaning agent
used.
1.2.2 Cleaning
The gun must be switched off when being cleaned and should never be
sprayed in "closed" containers (formation of a gas air/mixture which can
explode). The containers must be earthed.
1.2.3 Safety
Spraying can only be carried out safely, both for people and the environment, if
it is done in a spray booth or in front of a spraying wall with sufficient ventilation
(removal by suction).
In order to avoid occupational illness the safety regulations laid down by the
manufacturer of the paint or cleaning agent used must be adhered to during
preparation and application of the paint and while cleaning the equipment. In
particular, protective clothing, gloves, skin protection cream and breathing
equipment must be used to protect the skin and respiratory tracts.
1.2
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.
1.2.5 The spray gun and the high pressure hoses between the pump and the
spray gun must be of a sufficient quality for the pressure produced by the
pump.
A permanent marking on the high pressure hoses must indicate the maximum
permitted working pressure, the manufacturer and date of production.
Furthermore, it must be of a suitable quality so that the electric resistance
between the pump connection and the spray gun is less than 1 megaohm.
1.2.6 Earthing
Depending on the electrostatic charge and the flow speed of the spray an
electrostatic charge may, in certain cases, occur on the equipment. This could
cause a spark or flame on discharging. In order to avoid this the equipment
must always be earthed.
There must be a conductive connection (potential equalisation cable) between
the material container and the equipment.
All persons within the working area must wear shoes with electricallyconductive
soles (e.g. shoes with leather soles). Gloves must also be conductive, because
the operator is earthed through the handle of the spraygun. The floor of the
working area must be conductive, in accordance with VDE 0745, part 1,
paragraph 35: measurements according to DIN 51953.
1.2.7 Extraction systems
Paint mist extraction systems must be fitted on site according to the local
regulations.
1.2.8 Accessories and spare parts
The manufacturer's guarantee and product liability are only valid if original
Wagner accessories are used.
1.2.9 Safety information on harmless electrostatic discharges
If the plastic parts of the spray gun are touched with the hand this can result in
a harmless discharging (so-called brush discharge). The same occurs when
you electrostatically charge yourself by walking on a synthetic carpet and then
touch a metallic door handle, thus discharging the electrostatic charge. The
charge on the plastic parts is caused by the high-voltage field of the gun. The
discharging is completely safe for people and is not able to cause any ignition.
A corona glow may occur at the electrode end of the gun when it is in use (only
visible under dark conditions). A corona discharge can occur if the electrode
(spray gun) comes within a distance of 4 - 10 mm from the object being sprayed. The corona glow does not cause any ignition hazard.

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 manu-
facturer 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.
Only the usage of original WAGNER accessories and spare parts guarantees
that all safety regulations are observed.
Warranty
12 months / 6 months for multi-shift operation
This equipment is covered by the following manufacturing warranty:
All parts which prove unusable or the use of which is seriously impaired within
12 months or 6 months of receipt by the purchaser due to circumstances predating
receipt, such as faulty design, defective materials or poor workmanship, shall be
repaired or replaced at our discretion and free of charge.
No liability is assumed for damage attributable to the following factors:
Inappropriate or incorrect use, faulty installation or start-up by the purchaser or third
parties, natural wear and tear, as well as wear parts (marked * in the list of spare
parts), incorrect handling or maintenance.
The equipment must be checked immediately upon receipt. Obvious defects must be
reported to the supplier or to us in writing within 14 days of receipt in order to avoid
losing the right of complaint.
We reserve the right to assign warranty performances to a contractual partner.
Warranty performances shall only be rendered if the purchaser returns the warranty
card bearing the date of sale and seller's signature together with the equipment. The
repair costs will be charged to the purchaser if it is found that the warranty does not
apply.

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. This is enclosed
with the product or can be requested from the manufacturer. The CE identification
has been compulsory in Europe since 1st January 1995, and only products bearing
CE identification may be released into circulation.
EMC test:
The electromagnetic compatibility test forms an integral part of the CE conformity.
EMC tested products are built such that their interference radiation does not influence
other devices within the stipulated limits (noise on the radio, etc.). The EMC standard
differentiates between use in domestic, business and commercial or industrial areas.
Moreover, if required for comfort or safety reasons, products can be EMC tested for
their interference immunity. This means they are protected from the influence of
external interference.
